PRELIMINARY PROSPECTUS

Shares

Morgan Stanley Solana Trust

The Morgan Stanley Solana Trust (the “Trust”) is an exchange-traded fund that issues common shares of beneficial interest (the “Shares”) that are anticipated to be listed on NYSE Arca, Inc. (the “Exchange”). The Trust seeks to reflect generally the performance of the price of SOL and rewards from staking a portion of the Trust’s SOL, to the extent Morgan Stanley Investment Management Inc. (the “Delegated Sponsor”) in its sole discretion determines that the Trust may do so without incurring undue legal or regulatory risk, including, without limitation, any risk to the Trust’s qualification as a grantor trust for U.S. federal income tax purposes. The Trust is a passive investment vehicle that does not seek to generate returns beyond tracking the price of SOL tokens, the native digital asset of the Solana blockchain (“SOL”), and staking some portion of the SOL it holds (which may vary from time to time). This means the Delegated Sponsor does not speculatively sell SOL at times when its price is high or speculatively acquire SOL at low prices in the expectation of future price increases. It also means the Trust will not utilize leverage, derivatives or any similar arrangements in seeking to meet its investment objective. The Trust’s investment objective is to seek to track the performance of SOL, as measured by the performance of the CoinDesk Solana Benchmark 4PM NY Settlement Rate (the “Pricing Benchmark”), adjusted for the Trust’s expenses and other liabilities, and to reflect rewards from staking a portion of the Trust’s SOL. The Pricing Benchmark is calculated by CoinDesk Indices, Inc. (the “Benchmark Provider”) based on an aggregation of executed trade flow of major spot exchanges (“Constituent Exchanges”). The Pricing Benchmark is designed to reflect the performance of SOL in U.S. dollars. In seeking to achieve its investment objective, the Trust will hold SOL and will value its Shares daily based on the Pricing Benchmark.

The Delegated Sponsor intends to cause the Trust to engage in staking in connection with the commencement of this offering. To effectuate the staking of the Trust’s SOL one or more of the SOL Custodians (defined below) may enter into written agreements with one or more third-party staking services providers selected by the Delegated Sponsor (each, a “Staking Services Provider”), which may be either affiliates of the SOL Custodians or other approved third-party staking services providers, to stake the Trust’s SOL. Staking involves the SOL Custodians, each of which controls the private keys to the Trust’s SOL, delegating the Trust’s SOL that the Delegated Sponsor instructs such SOL Custodians to stake (“Staked Assets”) to validators on the Solana network. The SOL Custodians designate: (i) the Staking Services Provider as the validator for a specified amount of the Trust’s Staked Assets, allowing the Staking Services Provider to perform validation activities which maintain the security and integrity of the Solana network’s blockchain, verify transactions and add new blocks (“Validation Activities”), and (ii) the Trust’s own segregated custody account at each SOL Custodian, the private keys to which the SOL Custodians holds in offline storage, as the withdrawal address for both applicable staking rewards and the underlying staked assets themselves after they are un-staked by such SOL Custodian at the Delegated Sponsor’s instruction. The Staking Services Provider then uses its validator credentials to perform Validation Activities with the Trust’s Staked Assets that are staked with such Staking Services Provider. The Staking Services Provider does not control the cold storage private keys and thus cannot transfer, withdraw, or take possession or ownership of the Trust’s Staked Assets when staked with such Staking Services Provider. Instead, such Staked Assets remain in one or more on-chain stake accounts and remain delegated to the applicable validator until the SOL Custodian or the Staking Services Provider deactivates the delegation, at the Delegated Sponsor’s instruction, at which point the Trust’s Staked Assets are returned to the Trust’s Vault Account at the SOL Custodian. The Delegated Sponsor’s choice of third-party Staking Services Providers, and their decision to allocate SOL amongst chosen Staking Services Providers, will be based on a range of factors, including but not limited to the performance, reliability, and reputation of the Staking Services Provider, including monitoring their uptime.

Following the commencement of this Offering, and subject to the Delegated Sponsor's determination that the Trust may do so without undue legal, regulatory or tax risk, the Trust may instead seek to utilize alternative means to engage in Staking Activities. No such alternative means are contemplated to be utilized in connection with the commencement of this Offering and no determination has been made as of the date of this Prospectus as to which alternative means, if any, the Trust may utilize in the future. Should the Trust adopt any alternative means to engage Staking Activities, the Trust will notify the owners of beneficial interests of Shares in a prospectus supplement or its periodic Exchange Act reports, as applicable and on the Delegated Sponsor’s website.

Morgan Stanley Investment Management Inc. (the “Delegated Sponsor”) is the delegated sponsor of the Trust, CSC Delaware Trust Company (the “DE Trustee”), a Delaware trust company and AGS Trustees Limited, a company incorporated in the Cayman Islands with limited liability and registered with the Cayman Islands Monetary Authority (the “Cayman Trustee”) are the trustees of the Trust (the DE trustee and the Cayman Trustee, each individually a “Trustee” and together, the “Trustees”). The Cayman Trustee is a wholly owned controlled subsidiary of Appleby Global Services (Cayman) Limited, also a company incorporated in the Cayman Islands with limited liability, which holds a Full Mutual Fund Administrator and Trust license with the Cayman Islands Monetary Authority. Each of the Cayman Trustee and Appleby Global Services (Cayman) Limited is a regulated entity in the Cayman Islands. The Bank of New York Mellon (“BNY”) and Coinbase Custody Trust Company, LLC (the “Coinbase Custodian” and together with BNY, the “SOL Custodians”) have each been appointed as SOL custodians for the Trust. The Delegated Sponsor may determine, in its discretion, the allocation of the Trust’s SOL between the SOL Custodians from time to time. At any given time, one SOL Custodian may hold all, a portion of or none of the on the Trust’s SOL. The custodial services agreements with each of the SOL Custodians are collectively referred to herein as the “Custodial Services Agreements”). The Cayman Trustee has delegated substantially all day-to-day management and operational duties to the Delegated Sponsor pursuant to (i) a Trustee Services Agreement dated March 25, 2026 (the “Trustee Services Agreement”) and (ii) a Delegation of Trustee Duties Agreement dated March 25, 2026 (the “Delegation Agreement” and together with the Trustee Services Agreement, the “Appleby Agreements”), subject to certain limitations, as more fully described under “Duties of the Delegated Sponsor and the Trustees.”

The Trust is an exchange-traded fund. Barring a liquidation or extraordinary circumstances, the Trust does not intend on purchasing or selling SOL other than in connection with the creation and redemption of Shares and for distributions the Trust intends to make monthly (but at least quarterly) to distribute the staking rewards pursuant to current Internal Revenue Service (“IRS”) guidance. The Delegated Sponsor will also sell SOL to pay certain expenses and make staking-related distributions to Shareholders, which may be facilitated by the Prime Broker or any other prime brokers with whom the Trust contracts.

When the Trust sells or redeems its Shares, SOL will be transferred into or out of the Trust, as applicable, in exchange for blocks of 10,000 Shares (a “Basket”) that are based on the quantity of SOL attributable to each Share of the Trust (net of accrued but unpaid Delegated Sponsor Fees and any accrued but unpaid extraordinary expenses or liabilities).

Financial firms that are authorized to purchase Shares from or redeem Shares to the Trust (known as “Authorized Participants”) may purchase Shares in cash by depositing cash in the Trust’s account with the Cash Custodian. This will cause the Delegated Sponsor, on behalf of the Trust, to automatically instruct a designated third party, who is not an Authorized Participant but who may be an affiliate of an Authorized Participant and with whom the Delegated Sponsor has entered into an agreement on behalf of the Trust (each such third party, or the Prime Broker or the Lender, as applicable, a “SOL Counterparty”), to (i) purchase the amount of SOL equivalent in value to the cash deposit amount associated with the order and (ii) deposit the resulting SOL amount in the Trust’s account with the SOL Custodians, resulting in the Transfer Agent crediting the applicable amount of Shares to the Authorized Participant. Authorized Participants may also purchase Shares in-kind. To purchase Shares in-kind, an Authorized Participant delivers, or arranges for the delivery by the Authorized Participant’s designated agent of, SOL to the Trust’s account with the SOL Custodians in exchange for Shares.

When such an Authorized Participant redeems its Shares in cash, the Delegated Sponsor, on behalf of the Trust will direct the SOL Custodians to transfer SOL to a SOL Counterparty, who will sell the SOL to be executed, in the Delegated Sponsor’s reasonable efforts, at the Pricing Benchmark price used by the Trust to calculate the Trust’s net asset value (“NAV”), taking into account any spread, commissions, or other trading costs and deposit the cash proceeds of such sale in the Trust’s account with the Cash Custodian for settlement with the Authorized Participant. Any slippage incurred (including, but not limited to, any trading fees, spreads, or commissions), on a cash equivalent basis, will be the responsibility of the Authorized Participant and not of the Trust or Delegated Sponsor. Authorized Participants may also redeem Shares in-kind. When such an Authorized Participant redeems Shares in-kind, the Trust, through the SOL Custodians, will deliver SOL to the Authorized Participant, or a designated agent thereof, in exchange for its Shares.

The SOL Counterparty is a designated third party with whom the Delegated Sponsor has entered into an agreement on behalf of the Trust that will deliver, receive or convert to U.S. dollars the SOL related to the Authorized Participant’s cash creation or redemption orders. As part of this process, the Delegated Sponsor assesses SOL Counterparty candidates against various criteria, including those relating to candidates’ (1) financial standing, (2) reputation, (3) settlement history with the Delegated Sponsor, and (4) their regulatory oversight. The Trust will create Shares by receiving SOL from a SOL Counterparty that is not the Authorized Participant, and the Trust — not the Authorized Participant — is responsible for selecting the SOL Counterparty to deliver the SOL. Further, the SOL Counterparty will not be acting as an agent of the Authorized Participant with respect to the delivery of the SOL to the Trust or acting at the direction of the Authorized Participant with respect to the delivery of the SOL to the Trust.

Authorized Participants may then offer Shares to the public at prices that depend on various factors, including the supply and demand for Shares, the value of the Trust’s assets, and market conditions at the time of a transaction. Shareholders who buy or sell Shares during the day from their broker on the secondary market may do so at a premium or discount relative to the NAV of the Shares of the Trust.

Except when aggregated in Baskets, Shares are not redeemable securities. Baskets are only redeemable by Authorized Participants.

On July 8, 2026, the Pricing Benchmark was approximately $77.15.

The Delegated Sponsor served as the Audit Seed Investor to the Trust. On June 15, 2026, the Delegated Sponsor, in its capacity as Audit Seed Investor, subject to conditions, purchased Seed Creation Baskets comprising 5 Shares at a per-Share price of $20.00 as described in “Audit Seed/Initial Seed Creation Investor/Selling Shareholder.” Total proceeds to the Trust from the sale of these Seed Creation Baskets were $100.00. Delivery of the Seed Creation Baskets was made on June 15, 2026. These Seed Creation Baskets will be redeemed for cash prior to the effectiveness of the registration statement that this prospectus forms a part.

In connection with the initial listing of the Shares on the Exchange, we expect the Delegated Sponsor to purchase the initial seed creation baskets comprising 50,000 Shares (“Initial Seed Creation Baskets”). In this capacity, the Initial Seed Creation Investor will act as a statutory underwriter in connection with this purchase. The total proceeds to the Trust from the sale of the Initial Seed Creation Baskets are anticipated to be $1 million. Prior to the listing of the Shares on the Exchange, the Trust expects to purchase SOL with the proceeds of the Initial Seed Creation Baskets by transacting with a SOL Counterparty to acquire SOL on behalf of the Trust in exchange for cash provided by the Initial Seed Creation Investor. The SOL acquired in connection with the Initial Seed Creation Baskets will be held by the SOL Custodians. The price of the Shares comprising the Initial Seed Creation Baskets will be determined as of the effective date of the registration statement of which this Prospectus forms a part as described in this Prospectus, and such Shares could be sold at different prices if sold by the Initial Seed Creation Investor at different times. It is anticipated that the Initial Seed Creation Investor may redeem its Shares or sell its Shares to a third party in the weeks following the initial listing of Shares on the Exchange. The Initial Seed Creation Investor may sell some or all of its Shares pursuant to the registration statement of which this Prospectus forms a part (in such capacity, the "Selling Shareholder"), which Shares will have been registered to permit the resale from time to time after purchase. The Trust will not receive any of the proceeds from the resale or redemption by the Selling Shareholder of these Shares. The Delegated Sponsor will not receive from the Trust or any of its affiliates any fee or other compensation in connection with the resale of these Shares.

Shareholders who decide to buy or sell Shares of the Trust will place their trade orders through their brokers and will incur customary brokerage commissions and charges. Prior to this offering, there has been no public market for the Shares. The Shares are expected to be listed for trading, subject to notice of issuance, on the Exchange under the ticker symbol “MSOL.”

The offering of an indeterminate amount of the Trust’s Shares is registered with the Securities and Exchange Commission (the “SEC”) in accordance with the Securities Act of 1933, as amended (the “1933 Act”). The offering is intended to be a continuous offering and is not expected to terminate until three years from the date of the original offering, unless extended as permitted by applicable rules under the 1933 Act. The Trust is not an investment company registered under the Investment Company Act of 1940, as amended (the “1940 Act”), and is not subject to regulation under the 1940 Act. Investors in the Trust will not, therefore, receive the regulatory protections afforded by investment companies registered under the 1940 Act. The Delegated Sponsor is not acting in the capacity of an “Investment Adviser” (as defined in Section 202(a)(11) of the Investment Advisers Act of 1940, as amended (the “Advisers Act”)), the Delegated Sponsor’s provision of services to the Trust will not be governed by the Advisers Act, and the Delegated Sponsor is not subject to a fiduciary standard of care. The Trust is not a commodity pool for purposes of the Commodity Exchange Act of 1936, as amended (the “CEA”), and the Delegated Sponsor is not subject to regulation by the Commodity Futures Trading Commission (the “CFTC”) as a commodity pool operator or a commodity trading advisor. The Trust’s Shares are neither interests in nor obligations of the Delegated Sponsor or the Trustees. Shareholders in the Trust will not benefit from the protections afforded to investors in SOL futures contracts on regulated futures markets.

STATEMENT REGARDING FORWARD-LOOKING STATEMENTS

This Prospectus includes “forward-looking statements” that generally relate to future events or future performance. In some cases, you can identify forward-looking statements by terminology such as “may,” “will,” “should,” “expect,” “intend,” “plan,” “anticipate,” “believe,” “estimate,” “predict,” “potential” or the negative of these terms or other comparable terminology. All statements (other than statements of historical fact) included in this Prospectus that address activities, events or developments that will or may occur in the future, including such matters as movements in the digital asset markets and indexes that track such movements, the Trust’s operations, the Delegated Sponsor’s plans and references to the Trust’s future success and other similar matters, are forward-looking statements. These statements are only predictions. Actual events or results may differ materially. These statements are based upon certain assumptions and analyses the Delegated Sponsor has made based on its perception of historical trends, current conditions and expected future developments, as well as other factors appropriate in the circumstances.

Whether or not actual results and developments will conform to the Delegated Sponsor’s expectations and predictions, however, is subject to a number of risks and uncertainties, including the special considerations discussed in this Prospectus, general economic, market and business conditions, changes in laws or regulations, including those concerning taxes, made by governmental authorities or regulatory bodies, and other world economic and political developments. Consequently, all the forward-looking statements made in this Prospectus are qualified by these cautionary statements, and there can be no assurance that actual results or developments the Delegated Sponsor anticipates to occur will be realized or, even if substantially realized, that they will result in the expected consequences to, or have the expected effects on, the Trust’s operations or the value of its Shares.

Should one or more of these risks discussed in “Risk Factors” or other uncertainties materialize, or should underlying assumptions prove incorrect, actual outcomes may vary materially from those described in forward-looking statements. Forward-looking statements are made based on the Delegated Sponsor’s beliefs, estimates and opinions on the date the statements are made, and neither the Trust nor the Delegated Sponsor is under a duty or undertakes an obligation to update forward-looking statements if these beliefs, estimates and opinions or other circumstances should change, other than as required by applicable laws. Investors are therefore cautioned against placing undue reliance on forward-looking statements.

PROSPECTUS SUMMARY

This is only a summary of the Prospectus and, while it contains material information about the Trust and its Shares, it does not contain or summarize all of the information about the Trust and the Shares contained in this Prospectus that is material and/or which may be important to you. You should read this entire Prospectus before making an investment decision about the Shares.

Overview of the Trust

The Morgan Stanley Solana Trust (the “Trust”) is an exchange-traded fund that issues common shares of beneficial interest (the “Shares”) that trade on NYSE Arca, Inc. (the “Exchange”). The Trust’s investment objective is to seek to track the performance of SOL, as measured by the performance of the CoinDesk Solana Benchmark 4PM NY Settlement Rate (the “Pricing Benchmark”), adjusted for the Trust’s expenses and other liabilities, and to reflect rewards from staking a portion of the Trust’s SOL, to the extent the Delegated Sponsor in its sole discretion determines that the Trust may do so without incurring undue legal or regulatory risk, including, without limitation, any risk to the Trust’s qualification as a grantor trust for U.S. federal income tax purposes. The Pricing Benchmark is calculated by CoinDesk Indices, Inc. (the “Benchmark Provider”). The Pricing Benchmark is designed to reflect the performance of SOL in U.S. dollars. The Shares of the Trust are valued daily based on the Pricing Benchmark.

In seeking to achieve its investment objective, the Trust will hold SOL. The Delegated Sponsor of the Trust is Morgan Stanley Investment Management Inc. (the “Delegated Sponsor”), a wholly-owned subsidiary of Morgan Stanley.

The Trust does not provide investors with direct exposure to SOL, and an investment in the Trust is not a direct investment in SOL. Rather, the Trust provides investors with the opportunity to indirectly access the market for SOL through a traditional brokerage account without the potential barriers to entry or risks involved with holding or transferring SOL directly or acquiring it from a SOL spot market.

The Trust will custody its SOL at regulated third-party custodians, The Bank of New York Mellon (“BNY”) and Coinbase Custody Trust Company, LLC (the “Coinbase Custodian” and together with BNY, the “SOL Custodians”). The SOL Custodians are chartered as a New York state bank, in the case of BNY, and as a New York state limited liability trust company, in the case of Coinbase Custodian. The Coinbase Custodian provides custody and trade execution services for digital assets, and BNY provides custody services for digital assets. The SOL Custodians are not Federal Deposit Insurance Corporation (“FDIC”)-insured but carry insurance provided by private insurance carriers. The Trust, the Delegated Sponsor and the service providers will not loan or pledge the Trust's assets, including staked assets, nor will the Trust's assets, including staked assets, serve as collateral for any loan or similar arrangement, other than in connection with the Trade Financing Agreement or any line of credit entered into by the Trust for the purpose of managing liquidity. As part of the Trust’s liquidity management program, the Trust may establish various liquidity sources, which it may use to finance temporarily the redemption requests of Shareholders or for other short-term liquidity requirements. These liquidity sources may include borrowing arrangements made via uncommitted and committed lines of credit, which may involve the Trust's assets serving as collateral solely in connection with such arrangement. The Trust’s access to and use of such liquidity sources are considered by the Delegated Sponsor in assessing, managing, and periodically reviewing the Trust’s liquidity risk level. As part of the Trust’s liquidity management program, the Trust expects to establish a line of credit to facilitate liquidity management, which may involve the Trust's assets serving as collateral solely in connection with such arrangement. The Trust’s access to and use of such liquidity sources are considered by the Delegated Sponsor in assessing, managing, and periodically reviewing the Trust’s liquidity risk level.

The Trust will not invest in derivatives. The Delegated Sponsor believes that the Shares are designed to provide investors with a cost-effective and convenient way to gain exposure to SOL without purchasing, holding and trading SOL directly.

The amount of SOL represented by the Shares is expected to decline over time because of the transfer of the Trust’s SOL to pay the Delegated Sponsor Fee and other liabilities, regardless of whether the trading price of the Shares rise or fall. The decrease in the amount of SOL represented by the Shares due to paying the Delegated Sponsor Fee and other liabilities may be offset by net staking rewards, if any.

SOL and the Solana Network

SOL is a digital asset which serves as the unit of account on the open-source, peer-to-peer Solana network (“Solana” or “Solana network”). SOL may be used to pay for goods and services, including computational power on the Solana network, stored for future use, or converted to a fiat currency. The value of SOL is not backed by any government, corporation, or other identified body.

The value of SOL is determined in part by the supply of and demand for SOL in the markets for exchange that have been organized to facilitate the trading of SOL. As of July 6, 2026, SOL had a total market capitalization of approximately $47.62 billion, per CoinMarketCap. SOL is maintained on the Solana network. No single entity controls or administers the operations of the Solana network, although some entities like Solana Labs and the Solana Foundation exert significant influence. The Solana network is accessed through software and governs SOL’s creation and movement. The source code for the Solana network is open-source, and anyone can contribute to its development.

The Solana software source code allows for the creation of DApps that are supported by a transaction protocol referred to as “smart contracts,” which includes the cryptographic operations that verify and secure SOL transactions. A smart contract operates by a predefined set of rules (i.e., “if/then statements”) that allows it to automatically execute code the same way on any Solana node on the network. Such actions taken by the predefined set of rules are not necessarily contractual in nature but are intended to eliminate the involvement of a third party for carrying out code execution on behalf of users, making the system more decentralized, while empowering developers to create a wide range of applications layering together different smart contracts. Smart contracts can be utilized across several different applications ranging from art to finance. Currently, one of the most popular applications is the use of smart contracts for underpinning the operability of DeFi, which consist of numerous highly interoperable protocols and applications. DeFi offers many opportunities for innovation and has the potential to create an open, transparent, and immutable financial infrastructure, with democratized access.

The release of updates to the network’s source code by developers does not guarantee that the updates will be automatically adopted by the other participants. Users and validators must accept any changes made to the source code by downloading the proposed modification and that modification is effective only with respect to those users and validators who choose to download it. As a practical matter, a modification to the source code becomes part of the Solana network only if it is accepted by participants that collectively have a majority of the processing power on the Solana network.

If a modification is accepted by only a percentage of users and validators, a division will occur such that one network will run the pre-modification source code and the other network will run the modified source code. Such a division is known as a “fork.”

New SOL is created as a result of “staking” of SOL by validators. In the Solana network, validators stake SOL to compete to be randomly selected to validate transactions. Validation activities include verifying transactions, storing data, and adding to the Solana blockchain. Validators are rewarded SOL in proportion to the amount of SOL staked. SOL holders do not have to stake a minimum amount of SOL to become a Solana validator. The Solana network provides the ability to execute peer-to-peer transactions to realize, via smart contracts, automatic, conditional transfer of value and information, including money, voting rights, and property.

More specifically, staking on the Solana network refers to using SOL, or permitting SOL to be used, directly or indirectly, through an agent or otherwise, in the Solana network’s proof-of-stake validation protocol, in exchange for the receipt of consideration, including, but not limited to, staking rewards paid in kind.

Assets in the Solana network are held in accounts. Each account, or “wallet,” is made up of at least two components: a public address and a private key. A Solana private key controls the transfer or “spending” of SOL from its associated public SOL address. This design allows only the owner of SOL to send SOL, the intended recipient of SOL to unlock it, and the validation of the transaction and ownership to be verified by any third party anywhere in the world.

The Solana network employs a two-tier fee system, combining a small, fixed base fee and an optional priority fee. Solana’s base fee for every transaction is currently set at 0.000005 SOL. Users can choose to pay an optional priority fee to speed-up their transaction processing during periods of high network traffic. Unlike some other blockchains, Solana does not collect transaction fees in a central vault. Rather, Solana pools transaction fees in a recipient’s account. Half of all transaction fees are burned to combat inflation. The other half of all transaction fees goes directly to the leader validator who proposed the specific block.

The Solana network introduced the proof-of-history (“PoH”) timestamping mechanism. PoH automatically orders on-chain transactions by creating a historical record that proves an event has occurred at a specific moment in time. PoH operates by affixing a timestamp to every action occurring within the blockchain. The timestamps are linked together, establishing consensus on the precise sequence of events. The PoH timestamping mechanism may subject the Solana network and SOL to new and unexpected vulnerabilities not applicable to proof-of-work and proof-of-stake consensus models. For example, unlike those more established consensus mechanisms, PoH introduces novel risks specific to its architecture, including potential clock manipulation and transaction reordering by malicious leader nodes, targeted denial-of-service attacks enabled by the predictability of the published leader schedule, and network synchronization failures that could result in instability, forks, or transaction finality failures.

The Trust’s Investment Objective

The Trust’s investment objective is to seek to track the performance of SOL, as measured by the Pricing Benchmark, adjusted for the Trust’s expenses and other liabilities, and to reflect rewards from staking a portion of the Trust’s SOL. In seeking to achieve its investment objective, the Trust will hold SOL and will value its Shares daily as of 4:00 p.m. ET based on the Pricing Benchmark.

Barring the liquidation of the Trust or extraordinary circumstances (including but not limited to, non-recurring expenses and costs of services performed by the Delegated Sponsor or a service provider on behalf of the Trust to protect the Trust or the interests of Shareholders, such as in connection with any fork of the Solana blockchain, any indemnification of agents, service providers or counterparties of the Trust and extraordinary legal fees and expenses, including any legal fees and expenses incurred in connection with litigation, regulatory enforcement or investigation matters), the Trust generally will not purchase or sell SOL, other than in connection with the creation or redemption of Shares. The Delegated Sponsor will also sell SOL to pay certain expenses and make staking-related distributions to Shareholders, which may be facilitated by the Prime Broker or any other prime brokers with whom the Trust contracts.

Staking

The Delegated Sponsor intends to cause the Trust to engage in staking in connection with the commencement of this offering. To effectuate the staking of the Trust’s SOL (“Staking Activities”), one or more of the SOL Custodians may enter into written agreements (the “Staking Services Agreements”) with one or more third-party staking services providers selected by the Delegated Sponsor (each, a “Staking Services Provider”), which may be either affiliates of the SOL Custodians or other approved third-party staking services providers, to stake the Trust’s SOL. The Delegated Sponsor’s choice of third-party Staking Services Providers, and their decision to allocate SOL amongst chosen Staking Services Providers, will be based on a range of factors, including but not limited to the performance, reliability, and reputation of the Staking Services Provider, including monitoring their uptime. The SOL Custodians designate: (i) the Staking Services Provider as the validator for a specified amount of the Trust’s Staked Assets, allowing the Staking Services Provider to perform validation activities which maintain the security and integrity of the Solana network’s blockchain, verify transactions and add new blocks (“Validation Activities”), and (ii) the Trust’s own segregated custody account at each SOL Custodian, the private keys to which the SOL Custodians holds in offline (“cold”) storage, as the withdrawal address for both applicable staking rewards and the underlying staked assets themselves after they are un-staked by such SOL Custodian at the Delegated Sponsor’s instruction. The Staking Services Provider then uses its validator credentials to perform Validation Activities with the Trust’s Staked Assets that are staked with such Staking Services Provider. The Staking Services Provider does not control the cold storage private keys and thus cannot transfer or take possession or ownership of the Trust’s Staked Assets when staked with such Staking Services Provider. Instead, such Staked Assets remain delegated on the Solana network until un-staked by a SOL Custodian or the Staking Services Provider, at the Delegated Sponsor’s instruction, at which point the Trust’s Staked Assets are returned to the Trust’s Vault Account at the SOL Custodian. The Delegated Sponsor’s choice of third-party Staking Services Providers, and their decision to allocate SOL amongst chosen Staking Services Providers, will be based on a range of factors, including but not limited to the performance, reliability, and reputation of the Staking Services Provider, including monitoring their uptime.

The SOL Custodians and the Staking Services Providers will exercise no discretion as to the amount of the Trust's SOL to be staked or the timing of the Trust's Staking Activities. While the Trust may stake a maximum of 100% of its SOL holdings, the amount of SOL that remains unstaked will be determined based on the Trust’s Utilization Rate analysis, and accordingly may vary from time to time. The Staking Services Providers will exercise no discretion as to the amount of the Trust’s SOL to be staked or the timing of the Trust’s Staking Activities. Under normal market circumstances, and in accordance with the Trust’s liquidity risk management policy, the Delegated Sponsor intends to stake up to 100% of the Trust’s SOL, except that the Trust will occasionally maintain a portion of unstaked SOL to support liquidity (i) as necessary to pay the Delegated Sponsor Fee or any Trust expenses not assumed by the Delegated Sponsor, (ii) as necessary to satisfy existing and reasonably foreseen potential redemption orders, (iii) as necessary to make distributions of staking rewards earned by the Trust pursuant to current IRS guidance, (iv) if the Delegated Sponsor determines that Staking Activities raise significant governmental, policy or regulatory concerns or is subject or likely subject to a specialized regulatory regime, (v) if the Delegated Sponsor determines that any vulnerability exists in the source code, validator or client software, (vi) if the SOL Custodians or a Staking Services Provider discontinue their arrangements with the Trust (including any temporary suspension or un-staking instruction intended to protect the Trust’s assets against the risk of loss of ownership of the staked digital assets, but only with respect to the staked assets affected by the cessation or (vii) if the Delegated Sponsor otherwise determines that continued Staking Activities of such portion of the Trust’s assets would be inconsistent with the Trust’s purpose of protecting and conserving the value of the Trust. The Delegated Sponsor will determine such portion of unstaked SOL in accordance with the Trust’s SOL Liquidity Risk Policy.

All SOL received by the Trust in connection with the creation of new Shares, or as staking rewards, would also be staked upon receipt by the Trust, unless one or more of the exceptions described in clauses (i)-(vi) above applies. Moreover, any staked SOL which must be un-staked in order to fulfill a distribution in connection with a redemption (to the extent such distribution cannot be fulfilled utilizing the portion of the Trust’s SOL that has not been staked) will be un-staked only after the redemption order is approved by the Trust, the Delegated Sponsor executes an un-stake or withdrawal transaction through the SOL Custodian, and such transaction is processed by the Solana network. The Staking Services Provider will not be able to transfer un-staked SOL or staking rewards to another address on the Solana network.

Based on Utilization Rate analysis applied to historical data, the Trust generally intends to stake up to 100% of the SOL it holds, although the amount of SOL that is staked may be lesser or greater from time to time given that the Trust will periodically maintain a portion of unstaked SOL to support liquidity. The precise percentage to be staked will be based on the estimated liquidity needs of the Trust and other factors, as determined by the Delegated Sponsor in accordance with the Trust’s SOL Liquidity Risk Policy. In determining how to stake the SOL held by the Trust, and how much SOL to stake, the Trust’s model operates on the following key parameters:

· Unlocking period: The number of days required for unlocking staked assets as dictated by the protocol of the Solana Network;

· ETF Historical redemption patterns: The historical percentages of cumulative drawdowns in redemptions during the lock-up period for U.S. listed ETFs and other similar instruments listed abroad;

· Size of the Trust & Concentration: A trust with a high concentration of shareholders may have a higher percentage risk of redemption compared to a trust that has a diversified shareholder base and a large number of assets under management;

· Staking Services Provider performance: The model takes into account the performance, reliability, and reputation of Staking Services Providers. This includes adherence to certain minimum operating standards, including monitoring their uptime, and history of accruing penalties; and

· Market conditions monitoring: The model tracks market conditions, like regime shifts in momentum/liquidity, conditions of heightened demand or supply, network events, protocol changes, and other Staking Services Provider risks.

The Sponsor intends to make available on its website the current percentage of the Trust’s SOL being staked on a daily basis. None of the information on the Sponsor’s website is incorporated by reference into this Prospectus.

All SOL received by the Trust in connection with the creation of new Shares, or as staking rewards, would also be staked upon receipt by the Trust, unless permitted in accordance with the Trust’s liquidity risk management policy. Moreover, any staked SOL which must be un-staked in order to fulfill a distribution in connection with a redemption (to the extent such distribution cannot be fulfilled utilizing the portion of the Trust's SOL that has not been staked) will be un-staked only after the redemption order is approved by the Trust, the Delegated Sponsor executes an un-stake or withdrawal transaction through the SOL Custodian, and such transaction is processed by the Solana network. The Staking Services Provider will not be able to transfer un-staked SOL or staking rewards to another address on the Solana network.

Under the Trust's staking program, the Delegated Sponsor monitors and adjusts the amount of the Trust’s SOL to be staked in accordance with the Trust’s liquidity risk management policy. The Delegated Sponsor may instruct one or more SOL Custodians to stake the Trust's SOL. The SOL Custodians, which control the private keys to the Trust's SOL, create one or more stake accounts on the Solana network and delegate the Trust's Staked Assets from the Trust’s own segregated custody at each SOL Custodian (each, a “Cold Vault Balance”) to the Staking Services Provider's validator. The SOL Custodians designate (i) the Staking Services Provider as the validator in connection with a specified amount of the Trust's Staked Assets, and (ii) the Trust's own Cold Vault Balance as the withdrawal address for both staking rewards and the underlying staked assets themselves after they are un-staked by the SOL Custodians in accordance with the Trust’s liquidity risk management policy at the Delegated Sponsor's instruction. The Staking Services Provider then performs Validation Activities, operating validator software, including validator nodes, with the Trust's Staked Assets staked with such Staking Services Provider subject to slashing if the Staking Services Provider commits certain forms of misconduct when performing Validation Activities. The Staking Services Provider does not control the private keys to transfer or take possession or ownership of the Trust's Staked Assets when staked with such Staking Services Provider. Instead, the Staked Assets are held in stake accounts on the Solana network, over which the SOL Custodians retain the stake authority and withdraw authority, until un-staked by the SOL Custodians in accordance with the Trust’s liquidity risk management policy at the Delegated Sponsor's instruction, at which point the Trust's Staked Assets (and any related rewards) are transferred to the Cold Vault Balance at the SOL Custodians. The Staking Services Provider is the node operator and is obligated to perform Validation Activities with the Trust's Staked Assets consistent with the terms of the Trust's agreements with Staking Services Providers. The Trust retains control and ownership of the Trust's staked SOL because the SOL Custodians control the private keys to the Trust's Staked Assets. The Trust's Staked Assets are never transferred to a wallet address of the Staking Services Provider. The Trust also retains control given that the Delegated Sponsor (rather than the Staking Services Provider) will retain the ability through the SOL Custodians to un-stake its SOL at any time in accordance with the Trust’s liquidity risk management policy (subject to Solana network processes and delays). Moreover, the Trust's role will be limited to determining, from time to time, what portion of the Trust's SOL to stake and un-stake so as to maintain sufficient Trust assets to satisfy all outstanding redemption orders, and informing the Staking Services Provider(s) of those determinations. Under normal market circumstances, the Delegated Sponsor intends to stake up to 100% of the Trust's SOL, except that the Trust will occasionally maintain a portion of unstaked SOL to support liquidity.

The Trust expects to receive certain staking rewards from Staking Activities, which would be treated as giving rise to taxable income for U.S. federal income tax purposes under current Internal Revenue Service (“IRS”) guidance. See “U.S. Federal Income Tax Consequences” for further description of the tax implications of the receipt of staking rewards by the Trust. The Staking Services Providers shall exercise no discretion as to the amount of the Trust’s SOL to be staked or the timing of the Trust’s Staking Activities. The SOL Custodians will maintain exclusive possession and control of the Trust’s private keys associated with transferring any staked SOL at all times. Staking activity on the Solana network involves the delegation of SOL to validators and carries certain risks.

The Trust’s staking program aims to maximize the portion of the Trust’s SOL available for staking while controlling for liquidity and redemption risks. The model determines an optimal target range for the portion of assets staked, which is set by the Delegated Sponsor and which is based on factors including lock-up periods, historical and stressed redemption activity, Trust size, staking provider reliability, secondary market liquidity, and broader market conditions (the “Utilization Rate”) by balancing the factors relevant for evaluating liquidity and redemption risk.

The Staking Services Providers will exercise no discretion as to the amount of the Trust’s SOL to be staked or the timing of the Staking Activities. While the Trust seeks to stake a maximum of 100% of its SOL holdings, the amount of SOL that remains un-staked is determined based on the Trust’s Utilization Rate analysis, and accordingly may vary from time to time. Under normal market circumstances, and in accordance with the Trust’s liquidity risk management policy, the Delegated Sponsor intends to stake up to 100% of the Trust’s SOL, although the amount of SOL that is staked may be lesser or greater from time to time given that the Trust will periodically maintain a portion of unstaked SOL to support liquidity. The precise percentage to be staked will be based on the estimated liquidity needs of the Trust, as determined by the Delegated Sponsor based on a variety of factors. In determining how to stake the SOL held by the Trust, and how much SOL to stake, the Trust’s model operates on the following key parameters:

Unbonding period: The number of days/epochs required for unbonding staked assets as dictated by the Solana protocol;

ETF Historical redemption patterns: The historical percentages of cumulative drawdowns in redemptions during the bonding period for US listed ETFs and other similar instruments listed abroad;

Size of the Trust & Concentration: A trust with a high concentration of shareholders may have a higher percentage risk of redemption compared to a trust has a diversified shareholder base and a large number of assets under management;

Staking Services Provider performance: The model takes into account the performance, reliability, and reputation of staking services providers. This includes adherence to certain minimum operating standards, including monitoring their uptime, and slashing history; and

Market conditions monitoring: The model tracks market conditions, like regime shifts in momentum/liquidity, conditions of heightened demand or supply, network events and protocol changes, staking services provider risks.

The Trust intends to make available on its website the current percentage of the Trust’s SOL being staked on a daily basis.

The rewards owed or paid to the SOL Custodians as compensation for the Staking Services Providers reduce the amount of SOL rewards that are generated from the Trust’s Staking Activities that are available as the assets of the Trust. Each Staking Services Provider that generates staking rewards will be entitled to Staking Provider Consideration. The Staking Provider Consideration is paid directly to the Staking Services Provider from the staking rewards or indirectly through the SOL Custodians’ own accounts. The Staking Services Providers and SOL Custodians are expected to receive an aggregate of 5% of the staking rewards (the “Staking Fee”), with the remainder being retained by the Trust. The Delegated Sponsor will not receive or retain any portion of the staking rewards earned by the Trust. The expenses of staking the Trust’s SOL will be paid from the staking rewards generated by the Staking Activities. The staking rewards earned by the Trust will accrue to the Trust’s account with the SOL Custodians and will generally be staked in the same way as the Trust’s already staked SOL.

There is no guarantee as to the amount, if any, of staking rewards that may be earned by Staking Activities. Staking rewards will be added to the Trust’s assets and accrete to NAV, and NAV per share would be expected to increase until distributed. The Trust intends to distribute net staking rewards directly to Shareholders monthly (but at least quarterly) in accordance with current IRS guidance.

The Trust intends to pay cash distributions monthly (but at least quarterly) to Shareholders to distribute staking rewards earned by the Trust. Quarterly distributions are intended to represent all staking rewards accrued during the quarter. These rewards accrue in SOL, and at quarter-end, the Trust intends to sell an equivalent amount of SOL to fund the cash distribution. The Trust expects to fund the distribution solely from liquid (unbonded) SOL held by the Trust. The amount of any distribution, if any, will depend on the staking rewards actually earned by the Trust during each quarter and cannot be predicted with certainty. The amount of staking rewards earned will vary based on factors including, but not limited to, the amount of SOL held by the Trust, the percentage of the Trust’s SOL that is staked, network staking participation rates, protocol reward rates on the Solana network, and network conditions. Accordingly, there can be no assurance as to the amount of distributions that will be paid in any quarter, and it is possible that no distributions will be paid in a given quarter if insufficient staking rewards are earned.

The percentage of rewards to be paid to each such staking provider may vary. Rewards from staking will be shared, distributed and added to the assets of the Trust periodically. Specifically, staking rewards that accrue to the Trust on or before the calculation of the Trust’s end-of-day NAV will be added to the assets of the Trust, irrespective of whether the staked SOL has been unbonded at such time.

The historical average unbonding period for staked SOL was 2-4 days, with the epoch length decreasing over the last year to approximately 2 days for the one-year period ended on May 31, 2026. However, the unbonding period also may be longer than anticipated based on network activity.

Under normal network conditions, the bonding period for SOL is typically 2-3 days, i.e., one epoch. Note that the duration of the bonding period may depend on a range of factors including network load (the Solana protocol limits the amount of SOL that can be activated or deactivated in a single epoch to prevent major swings in staking distribution) and epoch timing (SOL that is delegated just before a new epoch begins may be subject to a shorter bonding period than SOL that is delegated just after a new epoch begins).

Due to the time involved in “exiting” the staking process, there is a risk that the Trust could become unable to timely meet excessive redemption requests in amounts that are greater than the portion of the Trust’s SOL that remains un-staked, leading to temporary delays in settlement and, in extreme scenarios, the temporary unavailability of the Trust’s redemption program. Moreover, any staked SOL which must be un-staked in order to fulfill a redemption (to the extent such redemption cannot be fulfilled utilizing the portion of the Trust’s SOL that has not been staked, or through another mechanism to manage liquidity in connection with Redemption Orders) will be un-staked only after the redemption request is approved by the Trust, the Delegated Sponsor executes an un-stake or withdrawal transaction through the SOL Custodians, and such transaction is processed by the Solana network. The Staking Provider will not be able to transfer un-staked SOL or Staking Provider Consideration to another address on the Solana network.

In addition, depending on the anticipated length of the unbonding period, the staked SOL may be classified as illiquid under the Trust’s liquidity risk management program. In addition, if SOL is determined to be offered or sold as a security under the Securities Act of 1933, as amended, it could be subject to significant constraints in terms of any transfer or disposal of such SOL. In such event, the Trust may consider SOL to be an “illiquid security,” which it defines as a security that the Trust reasonably expects cannot be sold or disposed of in current market conditions in seven calendar days or less without the sale or disposition significantly changing the market value of the security.

Rewards for staked SOL may be accrued in an epoch even before the staked SOL is unbonded. Once accrued, such SOL rewards are considered part of the Trust’s assets, even if unbonding has not occurred. The Delegated Sponsor and the Trust will manage liquidity in accordance with the Trust’s liquidity risk policies and procedures and will monitor staking and bonding/unbonding activity closely on a daily basis. For more information on the Trust’s liquidity risk policies and procedures, see “Staking of the Trust’s Assets—Liquidity Risk Policies and Procedures.”

On the Solana network, in addition to staking rewards there are block rewards that are paid to private validators. Block rewards are not newly-minted SOL from inflation, but are composed of transaction fees, with half the fee being burned and the other half going to the validator who produces and validates the block. Validators also earn through inflation rewards for securing the network and may receive additional revenue from maximal extractable value (“MEV”). Validators are paid immediately upon block production, and delegators receive their share of rewards from the validator they stake with, usually at the end of an epoch. As such, block rewards and transaction fees are not considered staking rewards and will not accrete to the Trust.

Due to the time involved in “exiting” the staking process, there is a risk that the Trust could become unable to timely meet excessive redemption requests in amounts that are greater than the portion of the Trust’s SOL that remains un-staked, leading to temporary delays in settlement and, in extreme scenarios, the temporary unavailability of the Trust’s redemption program. Moreover, any staked SOL which must be un-staked in order to fulfill a redemption (to the extent such redemption cannot be fulfilled utilizing the portion of the Trust’s SOL that has not been staked, or through another mechanism to manage liquidity in connection with Redemption Orders) will be un-staked only after the redemption request is approved by the Delegated Sponsor, the Delegated Sponsor executes an un-stake or withdrawal transaction through the SOL Custodians, and such transaction is processed by the Solana network. The Staking Services Provider will not be able to transfer un-staked SOL or Staking Provider Consideration to another address on the Solana network.

There is no guarantee that the Trust will receive any rewards with respect to staked SOL. Past rewards are not indicative of future returns. The staking rewards that the Trust may receive from staking SOL, if any, may be affected by, among other factors:

the total amount of SOL staked by users of the Solana network;

the total amount of SOL staked by the Trust;

changes to the Solana network as a result of protocol governance decisions;

changes to validator fees or commission rates set by the validators, including the commission charged by the Staking Services Provider (if any);

halts, outages or other anticipated or unanticipated interruptions affecting the Solana network or third-party service providers involved in the staking of the Trust’s SOL;

anticipated or unanticipated downtime by the Staking Services Provider;

loss or deprivation of SOL as a result of a violation of the Solana network’s rules by the Staking Services Provider;

validators ceasing to be eligible to participate in the Solana network’s proof-of-stake protocol and earn rewards;

“bonding,” “unbonding” or other SOL lock-up periods specified by the Solana network; and

delays or other operational factors related to or otherwise impacting the Trust’s Staking Activities.

Selling or Redeeming Shares

When the Trust sells or redeems its Shares, SOL will be transferred into or out of the Trust, as applicable, in exchange for a Basket that is based on the quantity of SOL attributable to each Share of the Trust (net of accrued but unpaid Delegated Sponsor Fees and any accrued but unpaid extraordinary expenses or liabilities).

Financial firms that are authorized to purchase Shares from or redeem Shares to the Trust (known as “Authorized Participants”) may purchase Shares in cash by depositing cash in the Trust’s account with the Cash Custodian. This will cause the Delegated Sponsor, on behalf of the Trust, to automatically instruct a designated third party, who is not an Authorized Participant but who may be an affiliate of an Authorized Participant and with whom the Delegated Sponsor has entered into an agreement on behalf of the Trust (each such third party, or the Prime Broker or Lender, as applicable, a “SOL Counterparty”), to (i) purchase the amount of SOL equivalent in value to the cash deposit amount associated with the order and (ii) deposit the resulting SOL amount in the Trust’s account with the SOL Custodians, resulting in the Transfer Agent crediting the applicable amount of Shares to the Authorized Participant. Authorized Participants may also purchase Shares in-kind. To purchase Shares in-kind, an Authorized Participant delivers, or arranges for the delivery by the Authorized Participant’s designated agent of, SOL to the Trust’s account with the SOL Custodians in exchange for Shares.

When such an Authorized Participant redeems its Shares in cash, the Delegated Sponsor, on behalf of the Trust will direct the SOL Custodians to transfer SOL to the SOL Counterparty, who will sell the SOL to be executed, in the Delegated Sponsor’s reasonable efforts, at the Pricing Benchmark price used by the Trust to calculate the Trust’s net asset value (“NAV”), taking into account any spread, commissions, or other trading costs and deposit the cash proceeds of such sale in the Trust’s account with the Cash Custodian for settlement with the Authorized Participant. Any slippage incurred (including, but not limited to, any trading fees, spreads, or commissions), on a cash equivalent basis, will be the responsibility of the Authorized Participant and not of the Trust or Delegated Sponsor. Authorized Participants may also redeem Shares in-kind. When such an Authorized Participant redeems Shares in-kind, the Trust, through the SOL Custodians, will deliver SOL to the Authorized Participant, or a designated agent thereof, in exchange for its Shares.

The SOL Counterparty is a designated third party with whom the Delegated Sponsor has entered into an agreement on behalf of the Trust that will deliver, receive or convert to U.S. dollars the SOL related to the Authorized Participant’s cash creation or redemption orders. In connection with cash creation orders, the Trust will create Shares by receiving SOL from a SOL Counterparty that is not the Authorized Participant, and the Trust — not the Authorized Participant — is responsible for selecting the SOL Counterparty to deliver the SOL. Further, the SOL Counterparty will not be acting as an agent of the Authorized Participant with respect to the delivery of the SOL to the Trust or acting at the direction of the Authorized Participant with respect to the delivery of the SOL to the Trust.

In connection with SOL cash redemption orders, the Trust will redeem Shares by delivering SOL to a SOL Counterparty that is not the Authorized Participant, and the Trust––not the Authorized Participant––is responsible for selecting the SOL Counterparty to receive the SOL. Further, the SOL Counterparty will not be acting as an agent of the Authorized Participant with respect to the receipt of the SOL from the Trust.

As of the date of this Prospectus, the Authorized Participants are Virtu Americas LLC, Jane Street Capital, LLC, Macquarie Capital (USA) Inc. and Goldman Sachs & Co. LLC. As of the date of this Prospectus, the Prime Broker, Coinbase, Inc., and the Lender, Coinbase Credit, Inc., serve as SOL Counterparties, among others. The Trust and/or Delegated Sponsor will bear the expense and risk of delivery and ownership of SOL once such SOL has been received by the SOL Custodians on behalf of the Trust and until transferred by the SOL Custodians on behalf of the Trust to the SOL Counterparty for conversion to cash.

All of the Trust’s SOL will be held by the SOL Custodians. The Transfer Agent will facilitate the processing of purchase and sale orders in Baskets to and from the Trust.

The CoinDesk Solana Benchmark 4PM NY Settlement Rate

The Pricing Benchmark was introduced on February 28, 2022. The Benchmark Provider is the administrator of the Pricing Benchmark. The Pricing Benchmark is calculated daily.

The Delegated Sponsor believes that the use of the Pricing Benchmark is reflective of a reasonable valuation of the average spot price of SOL. The Pricing Benchmark is derived from the CoinDesk Benchmark Rates, a set of reference rates used by the Benchmark Provider, that generally support the largest and most liquid digital assets and provide constituent pricing for the CoinDesk 20 family of indices and other multi- and single-asset products as needed.

CoinDesk Benchmark Rates source prices from a minimum of three exchanges and use USD and USD Coin denominated trading pairs. Volume data from the applicable exchanges is used as an input alongside the CoinDesk Benchmark Rates to produce a volume-weighted average price for the relevant digital asset. The Pricing Benchmark reflects a one-hour volume-weighted average price of the spot CoinDesk Benchmark Rates for single digital assets denominated in U.S. dollars.

The Pricing Benchmark is calculated at the top of each hour, with intermediate values published once every five seconds. The Pricing Benchmark utilizes an averaging look-back period, which resets at the beginning of each hour and accumulates on a rolling basis throughout the course of that hour. At the conclusion of each hour, the look-back period reflects a full 60-minute window of trading activity. Daily settlement rates are also published at 4:00 p.m. London time, 4:00 p.m. ET and other times as needed.

Reference prices used in calculating the Pricing Benchmark are sourced from the Benchmark Provider, which applies a defined exchange eligibility methodology to determine which digital asset exchanges may contribute to price data. Under this framework, only centralized spot exchanges that receive a minimum grade of BB or higher in the Benchmark Provider’s Exchange Benchmark (the “CoinDesk Exchange Benchmark”) are deemed eligible. The CoinDesk Exchange Benchmark is an independent assessment of exchanges based on categories and metrics as described below. The grading scale is from AA (best) through A, BB, B, C, D, E, to F (worst).

The categories and metrics the Benchmark Provider uses to select eligible digital trading platforms are the following:

· Market Quality. This includes composition liquidity scores, volume scores, and index scores. It also assesses market maker incentives and frequency of flash crashes.

· Security. This assesses formal security certificates, SSL ratings (a security protocol), offline storage, the cold wallet ratio, key distribution, two-factor authentication, custody provider metrics, off-exchange settlement, OTC services, exchange hack metrics, and bug bounty metrics.

· Legal/Regulation. This assesses license types, VASP (virtual asset service provider) license quality scores, legal entities, industry/regulatory group membership, insurance provision (fiat and crypto), sanction compliance statements, and politically exposed persons statements.

· KYC/Transaction Risk. This includes strict KYC (know your customer)/AML (anti-money laundering)assessments, maximum KYC requirements, withdrawal limit assessments, transaction monitoring capabilities, and market surveillance capabilities.

· Data Provision. This assesses API response times, API rate limit; protocols such as Websocket or FIX, API status page, downtime, historical candlestick data, candlestick granularity, historical trade querying, API trading capabilities, API ease of use assessments, API data quality, orderbook provisions, max orderbook levels; and API documentation quality.

· Transparency. This assesses available proof of reserves, available proof of liabilities, auditor attestations of proof of reserves and proof of liabilities, audited financial statements, management/ownership assessments, communication transparency, asset listing procedures, and due diligence submissions.

· Team & Exchange. This assesses identity of chief executive officer, chief technology officer, chief compliance officer, chief information security officer (and equivalents); educational level per C-suite, years of relevant experience per C-suite, customer service offerings, and institutional/corporate/retail offerings.

· Negative Events. This assesses data breaches, major/minor fines, withdrawal freezes, awarded penalties, and others.

The Pricing Benchmark further requires exchanges to satisfy specified U.S. or global licensure criteria based on authorization to operate in major regulatory jurisdictions.

The Benchmark Provider reviews eligible digital trading platforms on a semi-annual basis. Exchange eligibility is subject to ongoing monitoring and periodic review, and the Benchmark Provider’s governance bodies retain discretion to exclude exchanges where necessary. The Pricing Benchmark and its inputs are reviewed monthly and on an ad hoc basis as needed, and the Benchmark Provider may discontinue the calculation and publication of the Pricing Benchmark based on its assessment of applicable underlying digital asset requirements.

In addition to the semi-annual review of eligible exchanges, the Benchmark Provider performs a monthly evaluation of eligible trading pairs that may contribute to the Pricing Benchmark. As of the date of this prospectus, the Pricing Benchmark incorporates SOL/U.S. dollar (“SOL/USD”) and SOL/USD Coin (“SOL/USDC”) trading pairs. Each trading pair is assessed against three criteria: (i) its liquidity; (ii) its price deviation relative to all other eligible trading pairs; and (iii) its price impact on the Pricing Benchmark, as determined by reference to its liquidity and deviation.

The Pricing Benchmark and its inputs are reviewed monthly and on an ad hoc basis as needed. The Benchmark Provider may discontinue the calculation and publication of the Pricing Benchmark if the underlying digital asset (in the case of the Pricing Benchmark, SOL) (i) is no longer used to support a multi-asset index or other single asset financial product; or (ii) fails to meet certain listing and liquidity requirements.

Pricing Benchmark data and the description of the Pricing Benchmark are based on information made publicly available by the Benchmark Provider on its website at https://indices.coindesk.com/documentation-and-governance. None of the information on the Benchmark Provider’s website is incorporated by reference into this Prospectus.

The Delegated Sponsor has entered into a licensing agreement with the Benchmark Provider to use the Pricing Benchmark. The Trust is entitled to use the Pricing Benchmark pursuant to a sub-licensing arrangement with the Delegated Sponsor. As the Pricing Benchmark is calculated as a price return, it currently does not track airdrops clones, or forks involving SOL. Accordingly, the Trust will not participate in airdrops, as further described below in “Risk factors — The inability to recognize the economic benefit of a ‘fork’ or an ‘airdrop’ could adversely impact an investment in the Trust.”

Pricing Information Available on the Exchange and Other Sources

The current market price per Share (symbol: “MSOL”) will be published continuously as trades occur throughout each trading day on the consolidated tape by market data vendors.

The intra-day indicative value per Share will be published by the Exchange once every 15 seconds throughout each trading day on the consolidated tape by market data vendors.

The intra-day indicative value per Share is calculated based on the Pricing Benchmark. The most recent end-of-day NAV will be published as of the close of business by market data vendors and will be available on the Delegated Sponsor’s website at www.morganstanley.com/im or any successor thereto, and will be published on the consolidated tape. None of the information on the Delegated Sponsor’s website is incorporated by reference into this Prospectus.

Any adjustments made to the Pricing Benchmark will be published on the Benchmark Provider’s website at https://indices.coindesk.com/documentation-and-governance or any successor thereto. None of the information on the Benchmark Provider’s website is incorporated by reference into this Prospectus.

The selection of exchanges for use in the Pricing Benchmark is based on the accessible venues where execution transactions for SOL will occur. The exchanges on which market participants primarily execute transactions for SOL may evolve from time to time, and the Benchmark Provider may make changes to the Constituent Exchanges comprising the Pricing Benchmark from time to time for this or other reasons. To the extent the Trust executes transactions for SOL, the exchanges on which the Trust executes transactions do not impact the Constituent Exchanges comprising the Pricing Benchmark. Although Constituent Exchanges are selected for inclusion within the Pricing Benchmark in accordance with specified criteria and eligibility standards, changes to the Constituent Exchanges may result in an impact on the pricing information reflected in the Pricing Benchmark. Once it has actual knowledge of material changes to the Constituent Exchanges used to calculate the Pricing Benchmark, the Trust will notify the owners of the beneficial interests of Shares in a prospectus supplement or in its periodic Exchange Act reports, as applicable, and on the Delegated Sponsor’s website.

The Delegated Sponsor may, in its sole discretion, as a delegate of the Cayman Trustee, change either the Pricing Benchmark or Benchmark Provider without Shareholder approval. Should such a change take place, the Trust will notify the owners of the beneficial interests of Shares through disclosure on the Delegated Sponsor’s website and in a Form 8-K filing.

The intra-day levels and closing levels of the Pricing Benchmark are published by the Benchmark Provider, and the closing NAV is published by the Administrator.

The Shares are not issued, sponsored, endorsed, sold or promoted by the Exchange, and the Exchange makes no representation regarding the advisability of investing in the Shares.

The Benchmark Provider makes no warranty, express or implied, as to the results to be obtained by any person or entity from the use of the Pricing Benchmark for any purpose. Pricing Benchmark information and any other data calculated and/or disseminated, in whole or part, by the Benchmark Provider is for informational purposes only, not intended for trading purposes, and provided on an “as is” basis. The Benchmark Provider does not warrant that the Pricing Benchmark information will be uninterrupted or error-free, or that defects will be corrected. The Benchmark Provider also does not recommend or make any representation as to possible benefits from any securities or investments, or third-party products or services. Shareholders should undertake their own due diligence regarding securities and investment practices.

For more information on the Pricing Benchmark and the Benchmark Provider, see “The Trust and SOL Prices” below.

The Trust’s Legal Structure

The Trust is a Delaware statutory trust, formed on December 16, 2025 pursuant to the Delaware Statutory Trust Act (“DSTA”). The Trust continuously issues Shares representing fractional undivided beneficial interest in, and ownership of, the Trust that may be purchased and sold on the Exchange. The Trust will operate pursuant to an Amended and Restated Trust Agreement (the “Trust Agreement”). CSC Delaware Trust Company, a Delaware trust company, is the Delaware trustee of the Trust (the “DE Trustee”). AGS Trustees Limited, a Cayman Islands limited liability company, also serves as a trustee to the Trust (the “Cayman Trustee”). The Cayman Trustee has delegated substantially all day-to-day management and operational duties to the Delegated Sponsor pursuant to a Delegation of Trustee Duties Agreement dated March 25, 2026 and the Cayman Trustee has otherwise entered into a Trustee Services Agreement dated March 25, 2026 (the “Trustee Services Agreement”) (the “Delegation Agreement” and together with the Trustee Services Agreement, the “Appleby Agreements”), subject to certain limitations. For a complete description of the delegation structure, including the scope of the Delegated Duties, the Cayman Trustee's reserved powers and approval rights, and the non-delegable responsibilities of the Cayman Trustee, see “Duties of the Delegated Sponsor and the Trustees” below. The Delegated Sponsor is a corporation formed in the state of Delaware on September 19, 1980.

The Trust’s Service Providers

The Delegated Sponsor

As a result of the delegation of duties from the Cayman Trustee pursuant to the Appleby Agreements, the Delegated Sponsor has operational authority over the Trust and is responsible for the management and administration of the Trust, including arranging for the creation of the Trust, ongoing registration of the Shares for their public offering in the United States and the listing of Shares on the Exchange. The delegated duties include, but are not limited to: entering into and maintaining contracts and agreements; establishing and maintaining accounts; causing legal title to Trust property to be held in the name of the Delegated Sponsor; appointing custodians and other service providers (subject to Cayman Trustee approval for custodians); maintaining control over custody accounts; depositing, withdrawing, paying, retaining and distributing Trust assets; supervising preparation of offering materials and amendments; paying or authorizing distributions and Trust expenses; arranging for and managing exchange listing of Shares; administering any staking program; admitting additional sponsors; delegating duties to service providers; effecting provisions regarding forks and airdrops; and exercising sole discretion over issuance of Shares, share divisions and combinations, and related matters (collectively, the “Delegated Duties”). The Cayman Trustee retains oversight responsibilities, the duty to monitor the Delegated Sponsor’s performance, approval rights over certain material transactions (including custodian appointments and changes to Trust preferences and powers), and ultimate fiduciary responsibility as set forth under the Trust Agreement.

The Trustees

The Trustees of the Trust are CSC Delaware Trust Company, a Delaware trust company (the “DE Trustee”), and AGS Trustees Limited, a Cayman Islands limited liability company (the “Cayman Trustee”) and act as the trustees of the Trust as required to, among other things, create a Delaware statutory trust in accordance with the Trust’s Declaration of Trust and the DSTA. The Cayman Trustee has delegated substantially all day-to-day management and operational duties to the Delegated Sponsor pursuant to the Appleby Agreements.

The Administrator

The Bank of New York Mellon serves as the Trust’s administrator (the “Administrator”). The Administrator’s principal address is 240 Greenwich Street, New York, New York 10286. Under the Fund Administration and Accounting Agreement, the Administrator provides necessary fund administration, tax and accounting services, including valuation and computation accounting services, and financial reporting for the maintenance and operations of the Trust. In addition, the Administrator makes available the office space, facilities, equipment and personnel required to provide such services.

The Transfer Agent

The Bank of New York Mellon serves as the transfer agent for the Trust (the “Transfer Agent”). The Transfer Agent: (1) performs and facilitates the purchases and redemption of Shares of the Trust and prepares and transmits information with respect to such purchases and redemptions; (2) prepares and transmits payments for dividends and distributions, if any, declared by the Trust; (3) maintains Shareholder accounts; (4) responds to correspondence by Trust Shareholders and others relating to its duties and (5) makes periodic reports to the Trust.

The Cash Custodian

The Bank of New York Mellon acts as custodian of the Trust’s cash and cash equivalents (the “Cash Custodian”). Pursuant to a cash custody agreement entered into with the Trust (the “Cash Custody Agreement”), the Cash Custodian will establish and maintain cash account(s) for the Trust, and, upon instructions from the Delegated Sponsor acting on behalf of the Trust, facilitate cash transfers and cash payments from the Trust’s account(s).

The SOL Custodians

The Bank of New York Mellon and Coinbase Custody Trust Company, LLC are expected to serve as the Trust’s SOL custodians (the “SOL Custodians”), The Trust may commence operations with its SOL held by one SOL Custodian and the allocation of the Trust’s SOL among the SOL Custodians may change from time to time at the Delegated Sponsor’s discretion. There can be no assurance as to the timing by which each SOL Custodian will begin holding SOL on behalf of the Trust, and one or more SOL Custodians may hold no SOL for an indefinite period following launch.

The SOL Custodians are authorized to serve as the Trust’s custodians under the Trust Agreement and pursuant to the terms and provisions of the Custodial Services Agreements. Under the Custodial Services Agreements with the SOL Custodians, the SOL Custodians are responsible for safekeeping all of the SOL owned by the Trust. The SOL Custodians were selected by the Delegated Sponsor. The SOL Custodians are responsible for opening accounts that hold the Trust’s SOL (such accounts, collectively, the “SOL Accounts”), as well as facilitating the transfer of SOL required for the operation of the Trust.

After diligent investigation, the Delegated Sponsor believes that the SOL Custodians’ policies, procedures, and controls for safekeeping, exclusively possessing, and controlling the Trust’s SOL holdings are consistent with industry best practices to protect against theft, loss, and unauthorized and accidental use of the private keys.

Although the SOL Custodians carry insurance, the SOL Custodians’ insurance does not cover any loss in value to SOL and only covers losses caused by certain events such as fraud or theft and, in such covered events, it is unlikely the insurance would cover the full amount of any losses incurred by the Trust. The insurance maintained by each SOL Custodian is shared among all of the respective SOL Custodians’ customers, is not specific to the Trust or to customers holding SOL with the SOL Custodians, and may not be available or sufficient to protect the Trust from all possible losses or sources of losses.

For more information on the SOL Custodians, see “Custody of the Trust’s Assets” below.

The Staking Services Providers

Figment Inc., Galaxy Blockchain Infrastructure LLC and Coinbase Canada, Inc., each a party unrelated to the Delegated Sponsor and Trustees, serve as the Staking Services Providers.

The Marketing Agent

Foreside Fund Services, LLC (the “Marketing Agent”) is responsible for reviewing and approving the marketing materials prepared by the Delegated Sponsor for compliance with applicable SEC and Financial Industry Regulatory Authority (“FINRA”) advertising laws, rules, and regulations.

The Trust’s Fees and Expenses

The Trust will pay the unitary Delegated Sponsor Fee which is accrued daily at an annualized rate of 0.14% of the net asset value of the Trust (the “Delegated Sponsor Fee”) and the amount of SOL payable in respect of each daily accrual shall be determined by reference to the Pricing Benchmark. The Delegated Sponsor Fee is paid by the Trust to the Delegated Sponsor as compensation for services performed under the Trust Agreement.

The Delegated Sponsor Fee shall be paid in cash and not less than monthly in arrears by the Trust. The Delegated Sponsor has agreed to pay all operating expenses (except for litigation expenses and other extraordinary expenses) out of the Delegated Sponsor Fee. Operating expenses assumed by the Delegated Sponsor include (i) the fee payable to the Marketing Agent for services it provides to the Trust, if applicable (the “Marketing Fee”), (ii) fees to the Administrator, if any, (iii) fees to the SOL Custodians, (iv) fees to the Transfer Agent, (v) fees to the Trust’s DE Trustee and Cayman Trustee, (vi) the fees and expenses related to the initial listing of Shares on the Exchange, (vii) the fees and expenses related to any future listing, trading or quotation of the Shares on any listing exchange or quotation system (including legal, marketing and audit fees and expenses), (viii) ordinary course legal fees and expenses but not litigation-related expenses, (ix) audit fees, (x) regulatory fees, including, if applicable, any fees relating to the registration of the Shares under the Securities Act of 1933, as amended (the “1933 Act”), or the Exchange Act, (xi) printing and mailing costs, (xii) costs of maintaining the Delegated Sponsor’s website and (xiii) applicable license fees (each, a “Sponsor-paid Expense,” and together, the “Sponsor-paid Expenses”), provided that any expense that qualifies as an Additional Trust Expense will be deemed to be an Additional Trust Expense and not a Sponsor-paid Expense. The Trust will be responsible for SOL-related on-chain transaction fees associated with creation and redemption transactions, and the Delegated Sponsor will assume such expenses of the Trust in consideration for the Delegated Sponsor Fee. There is currently no predetermined cap on the aggregate amount of Sponsor-paid expenses. Should the Trust implement a predetermined cap on aggregate Sponsor-paid expenses, the Trust will notify the owners of the beneficial interests of Shares in a prospectus supplement or in its periodic Exchange Act reports, as applicable, and on the Delegated Sponsor’s website.

The Delegated Sponsor will not, however, assume certain extraordinary, non-recurring expenses that are not Sponsor-paid Expenses, including, but not limited to, taxes and governmental charges, expenses and costs of any extraordinary services performed by the Delegated Sponsor (or any other service provider) on behalf of the Trust to protect the Trust or the interests of Shareholders, any indemnification of the SOL Custodians, Administrator or other agents, service providers or counter-parties of the Trust, and extraordinary legal fees and expenses, including any legal fees and expenses incurred in connection with litigation, regulatory enforcement or investigation matters (collectively, “Additional Trust Expenses”). The Delegated Sponsor will consider re-designating a Sponsor-paid Expense as an Additional Trust Expense, in its sole discretion as a delegate of the Cayman Trustee, if the Delegated Sponsor determines that (i) the expense is extraordinary, non-recurring, or unusual in nature or amount; (ii) the expense was not reasonably anticipated at the time the Delegated Sponsor agreed to assume such category of expenses; (iii) the expense results from changes in applicable law, regulation, or regulatory guidance that impose new or additional obligations on the Trust; (iv) the expense arises from circumstances outside the ordinary course of the Trust's operations; or (v) bearing such expense would be materially adverse to the Delegated Sponsor’s ability to continue performing its obligations under the Trust Agreement. Should such a change take place, the Trust will notify the owners of the beneficial interests of Shares in a prospectus supplement or in its periodic Exchange Act reports, as applicable, and on the Delegated Sponsor’s website. Pursuant to the Trust Agreement, the Delegated Sponsor or its delegates will direct the SOL Custodians to transfer SOL from the Trust’s Cold Vault Balance as needed to pay the Delegated Sponsor Fee and Additional Trust Expenses, if any. The Delegated Sponsor or its delegates will endeavor to transfer the smallest amount of SOL needed to pay applicable expenses. The Trust shall not be responsible for paying any fees or expenses associated with the transfer of SOL as needed to pay the Delegated Sponsor Fee or Additional Trust Expenses.

Custody of the Trust’s Assets

The SOL Custodians will maintain custody of all of the Trust’s SOL. The SOL Custodians provide insured safekeeping of digital assets using a multi-layer offline (“cold”) storage security platform designed to provide offline security of the digital assets held by the SOL Custodians. The SOL Custodians have insurance coverage as subsidiaries under their parent companies, which procure fidelity (e.g., crime) insurance to protect the organizations from risks such as theft of funds. Specifically, the fidelity program provides coverage for the theft of funds held in hot or cold storage. The insurance program is provided by a syndicate of industry-leading insurers. The insurance program does not cover, insure or guarantee the performance of the Trust. The SOL Custodians are not FDIC-insured. The insurance maintained by the SOL Custodians is shared among all of the SOL Custodians’ customers, is not specific to the Trust or to customers holding SOL with the SOL Custodians, and may not be available or sufficient to protect the Trust from all possible losses or sources of losses.

SOL may be held across multiple wallets, any of which will feature the following safety and security measures to be implemented by the SOL Custodians:

Cold Storage: Cold storage is a widely-used security precaution, especially when dealing with large amounts of SOL. SOL held under custodianship with the SOL Custodians will be kept in high-security, offline, multi-layer cold storage vaults. This means that the private keys, the cryptographic component that allows a user to access SOL, are stored offline on hardware that is not connected to the internet. Storing the private keys offline significantly reduces the risk of the SOL being stolen. All of the Trust’s assets and private keys will be held in cold storage of the SOL Custodians on an ongoing basis, but a portion of the Trust’s assets may be held in hot trading wallets, from time to time, in connection with the settlement, creation or redemption of a transaction (note, however, that not all SOL Custodians may maintain hot wallets for the holding and storage of digital assets). In connection with creations or redemptions, the Trust will, under most circumstances, process creations and redemptions by transferring SOL from its Cold Vault Balance to and/or from a SOL Counterparty. From time to time, portions of the Trust’s SOL temporarily may be held outside of cold storage in the Trading Balance maintained by Coinbase, Inc. (the “Prime Broker”) or a SOL Counterparty, including in circumstances in which it is necessary in connection with creations or redemptions of Baskets, to sell SOL to pay Trust expenses or make staking-related distributions to Shareholders.

Multiple Private Keys: All private keys are securely stored using multiple layers of high-quality encryption and in Custodian-controlled offline hardware vaults in secure environments. No customers or third parties are given access to the SOL Custodians’ private keys. The use of multiple private keys makes retrieving SOL from the wallet more difficult, and aims to further reduce the risk of hacking, theft and/or robbery.

Whitelisting: Transactions are only sent to vetted, known addresses. The SOL Custodians’ platform supports pre-approval and test transactions. The SOL Custodians require authentication when adding or removing addresses for whitelisting. All instructions to initiate a whitelist addition or removal must be submitted via the Coinbase Custodian’s platform. When a whitelist addition or removal request is initiated, the initiating user will be prompted to authenticate their request using a two-factor authentication key. A consensus mechanism on the Coinbase Custodian’s platform dictates how many approvals are required in order for the consensus to be achieved to add or remove a whitelisted address. Only when the consensus is met is the underlying transaction considered officially approved. An account’s roster and user roles are maintained by the SOL Custodians in a separate log, an Authorized User List (“AUL”). Any changes to the account’s roster must be reflected on an updated AUL first and executed by an authorized signatory.

Audit Trails: Audit trails exist for all movement of SOL within SOL Custodian-controlled SOL wallets and are audited annually for accuracy and completeness by an independent external audit firm.

In addition to the above measures, in accordance with the Custodial Services Agreements, SOL held in custody with the SOL Custodians will be segregated from both the proprietary property of the SOL Custodians and the assets of any other customer in accounts that clearly identify the Trust as the owner of the accounts. Therefore, in the event of an insolvency of the SOL Custodians, assets held in the segregated accounts would not become property of the SOL Custodians’ estate and would not be available to satisfy claims of creditors of the SOL Custodians.

The SOL Custodians maintain internal audit teams that perform periodic internal audits over custody operations. Systems and Organizational Control (“SOC”) attestations are also performed on the SOL Custodians’ services. BNY currently produces a SOC 1 Type 1 report and the Coinbase Custodian currently produces SOC 1 Type 2 and SOC 2 Type 2 reports.

The Transfer Agent will facilitate the settlement of Shares in response to the placement of creation orders and redemption orders from Authorized Participants. The Trust generally does not intend to hold cash or cash equivalents. However, there may be situations where the Trust will hold cash on a temporary basis, including in connection with the creation and redemption process.

The Trust has entered into the Cash Custody Agreement, pursuant to which the Cash Custodian will establish and maintain cash account(s) for the Trust and, upon instructions from the Delegated Sponsor acting on behalf of the Trust, facilitate cash transfers and cash payments from the Trust’s account(s).

For more information on the Trust’s custody arrangements with the SOL Custodians and the Prime Broker, see “Custody of the Trust’s Assets” and “Prime Broker” below.

NAV Determinations

As described in more detail below in “NAV Determinations,” the Administrator daily calculates NAV and NAV per Share on each day that the Exchange is open for regular trading, as promptly as practicable after 4:00 p.m. ET, based on the Pricing Benchmark. In determining the Trust’s NAV, the Administrator values the SOL held by the Trust based on the price set by the Pricing Benchmark as of 4:00 p.m. ET. The Delegated Sponsor believes that use of the Pricing Benchmark mitigates against idiosyncratic market risk, as the failure of any individual spot market will not materially impact pricing for the Trust. It also allows the Administrator to calculate the NAV in a manner that significantly deters manipulation.

However, determining the value of the Trust’s SOL using the Pricing Benchmark is not in accordance with U.S. generally accepted accounting principles (“GAAP”), and therefore, the Pricing Benchmark is not used in the Trust’s financial statements. The Trust’s SOL are carried, for financial statement purposes, at fair value, as required by GAAP. The Trust determines the fair value of SOL based on the price provided by the SOL market that the Trust considers its “principal market” as of 11:59:59 p.m. ET on the valuation date. The NAV of the Trust determined on a GAAP basis is referred to in this Prospectus as a “Principal Market NAV,” and the NAV of the Trust per Share determined on a GAAP basis is referred to as “Principal Market NAV per Share.”

NAV and NAV per Share are not measures calculated in accordance with GAAP and are not intended as a substitute for the Principal Market NAV and Principal Market NAV per Share, respectively.

Plan of Distribution; Selling Shareholder

Barring the liquidation of the Trust or extraordinary circumstances (including but not limited to, non-recurring expenses and costs of services performed by the Delegated Sponsor or a service provider on behalf of the Trust to protect the Trust or the interests of Shareholders, such as in connection with any fork of the SOL blockchain, any indemnification of agents, service providers or counterparties of the Trust and extraordinary legal fees and expenses, including any legal fees and expenses incurred in connection with litigation, regulatory enforcement or investigation matters), the Trust will not purchase or sell SOL other than in connection with the creation and redemption of Shares and for distributions to be made at least quarterly to distribute the staking rewards earned by the Trust pursuant to current IRS guidance. The Delegated Sponsor will also sell SOL to pay certain expenses and make staking-related distributions to Shareholders, which may be facilitated by the Prime Broker or any other prime brokers with whom the Trust contracts.

When the Trust sells or redeems its Shares, SOL will be transferred into or out of the Trust, as applicable, in exchange for Baskets that are based on the quantity of SOL attributable to each Share of the Trust (net of accrued but unpaid Delegated Sponsor Fees and any accrued but unpaid extraordinary expenses or liabilities).

Authorized Participants may purchase Shares in cash by depositing cash in the Trust’s account with the Cash Custodian. This will cause the Delegated Sponsor, on behalf of the Trust, to automatically instruct a SOL Counterparty to (i) purchase the amount of SOL equivalent in value to the cash deposit amount associated with the order and (ii) deposit the resulting SOL amount in the Trust’s account with the SOL Custodians, resulting in the Transfer Agent crediting the applicable amount of Shares to the Authorized Participant. Authorized Participants may also purchase Shares in-kind. To purchase Shares in-kind, an Authorized Participant delivers, or arranges for the delivery by an Authorized Participant’s designated agent of, SOL to the Trust’s account with the SOL Custodians in exchange for Shares.

When such an Authorized Participant redeems its Shares in cash, the Delegated Sponsor, on behalf of the Trust will direct the SOL Custodians to transfer SOL to the SOL Counterparty, who will sell the SOL to be executed, in the Delegated Sponsor’s reasonable efforts, at the Pricing Benchmark price used by the Trust to calculate NAV, taking into account any spread, commissions, or other trading costs and deposit the cash proceeds of such sale in the Trust’s account with the Cash Custodian for settlement with the Authorized Participant. Any slippage incurred (including, but not limited to, any trading fees, spreads, or commissions), on a cash equivalent basis, will be the responsibility of the Authorized Participant and not of the Trust or Delegated Sponsor. Authorized Participants may also redeem Shares in-kind. When such an Authorized Participant redeems Shares in-kind, the Trust, through the SOL Custodians, will deliver SOL to the Authorized Participant, or a designated agent thereof, in exchange for its Shares.

The Initial Seed Creation Investor may sell some or all of its Shares pursuant to the registration statement of which this Prospectus forms a part (in such capacity, the "Selling Shareholder"), which Shares will have been registered to permit the resale from time to time after purchase. The Shares offered by the Selling Shareholder were acquired by the Selling Shareholder as described in the registration statement and could be sold at different times and at different offering prices. The Trust will not receive any of the proceeds from the resale or redemption by the Selling Shareholder of these Shares. The Selling Shareholder will not receive from the Trust or any of its affiliates any fee or other compensation in connection with the resale of these Shares.

The Trust and/or Delegated Sponsor will bear the expense and risk of delivery and ownership of SOL once such SOL has been received by the SOL Custodians on behalf of the Trust and until transferred by the SOL Custodians on behalf of the Trust to the SOL Counterparty for conversion to cash.

Only Authorized Participants may purchase Shares from or redeem Shares to the Trust. Authorized Participants may then offer Shares to the public at prices that depend on various factors, including the supply and demand for Shares, the value of the Trust’s assets, and market conditions at the time of a transaction. Shareholders who buy or sell Shares during the day from their broker may do so at a premium or discount relative to the NAV of the Shares of the Trust.

The Delegated Sponsor may enter into marketing support arrangements with respect to the Trust, to which the Trust would not be party. Any fees under such agreements would be payable by the Delegated Sponsor, as applicable, and not by the Trust.

Federal Income Tax Considerations

It is expected that an owner of Shares will be treated, for U.S. federal income tax purposes, as if they owned a proportionate share of the assets of the Trust. A Shareholder will accordingly include in the computation of their taxable income their proportionate share of the income (including staking income, as applicable) and expenses realized by the Trust. Each sale or other disposition of SOL by the Trust (including, under current Internal Revenue Service “IRS” guidance, the use or sale of SOL to pay expenses of the Trust or to make distributions) will give rise to gain or loss and will therefore constitute a taxable event for Shareholders. See “United States Federal Income Tax Consequences—Taxation of U.S. Shareholders.”

Use of Proceeds

Proceeds received by the Trust from the issuance of Baskets consist of SOL. Such deposits are held by the SOL Custodians on behalf of the Trust, during which time they may be employed in Staking Activities, until (i) delivered out in connection with redemptions of Baskets; or (ii) transferred or sold by the Delegated Sponsor, which may be facilitated by the SOL Custodians, to pay fees due to the Delegated Sponsor and Trust expenses and liabilities not assumed by the Delegated Sponsor.

Staking rewards received by the Trust from staking, net of the Staking Fee, are intended to be distributed monthly (but at least quarterly) by the Trust. The Delegated Sponsor intends to arrange for the conversion of all such staking rewards received by the Trust and available for distribution prior to the intended distribution date, net of the Staking Fee, to U.S. dollars shortly before the intended distribution, at the price available through SOL Counterparties which the Delegated Sponsor is able to obtain using commercially reasonable efforts. If no staking rewards from staking have been received by the Trust and is available for distribution prior to the intended distribution date, such as during the activation process for staking (when the Trust's assets will be staked, but no rewards will be earned yet), or during stressed conditions in which, consistent with the Trust's liquidity risk policies, the Delegated Sponsor chooses to prioritize using un-staked SOL to meet redemptions over distribution of staking rewards, or due to failures, delays, or defaults by the Trust's service providers, no distribution of staking rewards will be made at that time. See "Risk Factors- Risks Associated with SOL and the Solana network."

Emerging Growth Company

The Trust is an “emerging growth company” as defined in the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”). For as long as the Trust is an emerging growth company, unlike other public companies, it will not be required to, among other things: (i) provide an auditor’s attestation report on management’s assessment of the effectiveness of our system of internal control over financial reporting pursuant to Section 404(b) of the Sarbanes-Oxley Act of 2002; or (ii) comply with any new audit rules adopted by the Public Company Accounting Oversight Board (“PCAOB”) after April 5, 2012, unless the SEC determines otherwise.

The Trust will cease to be an “emerging growth company” upon the earliest of (i) it having $1.235 billion or more in gross annual revenues, (ii) at least $700 million in market value of Shares being held by non-affiliates, (iii) it issuing more than $1.0 billion of non-convertible debt over a three-year period or (iv) the last day of the fiscal year following the fifth anniversary of its initial public offering.

In addition, Section 107 of the JOBS Act also provides that an emerging growth company can take advantage of the extended transition period provided in Section 7(a)(2)(B) of the 1933 Act for complying with new or revised accounting standards. In other words, an emerging growth company can delay the adoption of certain accounting standards until those standards would otherwise apply to private companies. The Trust intends to take advantage of the benefits of the extended transition period.

Principal Investment Risks of an Investment in the Trust

An investment in the Trust involves a high degree of risk. Any investment made in the Trust may result in a total loss of the investment. There is no assurance that the Trust will generate a profit for investors. Some of the risks you may face are summarized below. A more extensive discussion of these risks appears beginning on page 22.

Risks Associated with SOL and the Solana network

Digital assets such as SOL were only introduced within the past decade, and the medium-to-long term value of the Shares is subject to a number of factors relating to the capabilities and development of blockchain technologies and to the fundamental investment characteristics of digital assets that are uncertain and difficult to evaluate.

The value of the Shares relates directly to the value of SOL, the value of which may be highly volatile and subject to fluctuations due to a number of factors.

The value of the Shares depends on the development and acceptance of the Solana network. The slowing or stopping of the development or acceptance of the Solana network may adversely affect an investment in the Trust.

Due to the nature of private keys, SOL transactions are irrevocable and stolen or incorrectly transferred SOL may be irretrievable. As a result, any incorrectly executed SOL transactions could adversely affect an investment in the Trust.

Security threats to the Trust’s account with the SOL Custodians could result in the halting of Trust operations and a loss of Trust assets or damage to the reputation of the Trust, each of which could result in a reduction in the price of the Shares.

Potential amendments to the Solana network’s protocols and software could, if accepted and authorized by the Solana network community, adversely affect an investment in the Trust

The Solana network is still in the process of developing and making significant decisions that will affect policies that govern the supply and issuance of SOL as well as other Solana network protocols.

Many digital asset networks, including Solana, face significant scaling challenges and are being upgraded with various features to increase the speed and throughput of digital asset transactions. These attempts to increase the volume of transactions may not be effective.

A temporary or permanent “fork” or a “clone” of the Solana blockchain could adversely affect an investment in the Trust.

The price of SOL on the SOL market has exhibited periods of extreme volatility, which could have a negative impact on the performance of the Trust. For example, between January 1, 2025 and December 31, 2025, the price of SOL ranged from $294.33 to $96.59, marking a drawdown of 61.54%. Likewise, during the first six months of calendar year 2026, the price of SOL ranged from $60.12 to $148.22.

A determination that SOL or any other digital asset is offered and sold as a “security” may adversely affect the price of SOL and the value of the Shares, and result in potentially extraordinary, nonrecurring expenses to, or termination of, the Trust.

SOL exchanges on which SOL trades are relatively new and, in some cases, unregulated, and, therefore, may be more exposed to fraud and security breaches than established, regulated exchanges for other financial assets or instruments, which could have a negative impact on the performance of the Trust.

New competing digital assets may pose a challenge to SOL’s current market position, resulting in a reduction in demand for SOL, which could have a negative impact on the price of SOL and may have a negative impact on the performance of the Trust.

Risks Associated with Investing in the Trust

The value of the Shares may be influenced by a variety of factors unrelated to the value of SOL.

The NAV or Principal Market NAV may not always correspond to the market price of SOL and, as a result, Creation Baskets may be created or redeemed at a value that is different from the market price of the Shares.

The inability of Authorized Participants and market makers to hedge their SOL exposure may adversely affect the liquidity of Shares and the value of an investment in the Shares.

The Trust is subject to risks due to its concentration of investments in a single asset.

Possible illiquid markets may exacerbate losses or increase the variability between the Trust’s NAV or the Principal Market NAV and its market price.

The amount of SOL represented by the Shares is expected to decline over time.

The Administrator is solely responsible for determining the value of the SOL holdings and SOL holdings per Share, and any errors, discontinuance or changes in such valuation calculations may have an adverse effect on the value of the Shares.

The use of cash creations and redemptions, as opposed to in-kind creations and redemptions, may adversely affect the arbitrage transactions by Authorized Participants intended to keep the price of the Shares closely linked to the price of SOL and, as a result, the price of the Shares may fall or otherwise diverge from NAV.

If the process of creation and redemption of Baskets encounters any unanticipated difficulties, the possibility for arbitrage transactions by Authorized Participants intended to keep the price of the Shares closely linked to the price of SOL may not exist and, as a result, the price of the Shares may fall or otherwise diverge from NAV.

Risks Associated with the Regulatory Environment of Solana

Future and current regulations by a United States or foreign government or quasi-governmental agency could have an adverse effect on an investment in the Trust, and SOL’s status as being offered and sold as a “security” under U.S. federal securities laws remains unsettled.

Shareholders do not have the protections associated with ownership of Shares in an investment company registered under the Investment Company Act of 1940 (the “1940 Act”) or the protections afforded by the Commodity Exchange Act, as amended (the “CEA”).

Future legal or regulatory developments may negatively affect the value of SOL or require the Trust or the Delegated Sponsor to become registered with the Securities and Exchange Commission (“SEC”) or Commodity Futures Trading Commission (“CFTC”), which may cause the Trust to incur unforeseen expenses or liquidate.

Risks Associated with the Tax Treatment of SOL

The ongoing activities of the Trust may generate tax liabilities for Shareholders.

The tax treatment of SOL and transactions involving SOL for state and local tax purposes is not settled.

A hard “fork” of the Solana blockchain or airdrop could result in Shareholders incurring a tax liability.

The tax treatment of SOL and transactions involving SOL, including staking, for U.S. federal income tax purposes may change.

SOL staking may result in adverse tax consequences for Shareholders.

The treatment of staking in a grantor trust for U.S. federal income tax purposes is still developing.

The intended tax treatment of the Trust will limit the flexibility of the Trust’s investment decisions.

Other Risks

The Exchange on which the Shares are listed may halt trading in the Trust’s Shares, which would adversely impact a Shareholder’s ability to sell Shares.

The market infrastructure of the SOL spot market could result in the absence of active Authorized Participants able to support the trading activity of the Trust, which would affect the liquidity of the Shares in the secondary market and make it difficult to dispose of Shares.

Shareholders that are not Authorized Participants may only purchase or sell their Shares in secondary trading markets, and the conditions associated with trading in secondary markets may adversely affect Shareholders’ investment in the Shares.

Shareholders do not have the rights enjoyed by investors in certain other vehicles and may be adversely affected by a lack of statutory rights and by limited voting and distribution rights. In certain circumstances, Shareholders may vote to appoint a successor Delegated Sponsor following the Voluntary Withdrawal of the Delegated Sponsor, or to continue the Trust in certain instances of dissolution of the Trust. Shareholders shall otherwise have no voting rights with respect to the Trust.

The Trust Agreement includes a provision restricting Shareholders’ right to bring a derivative action.

The liability of the Delegated Sponsor and the Trustees is limited, and the value of the Shares will be adversely affected if the Trust is required to indemnify the Trustees or the Delegated Sponsor.

Due to the increased use of technologies, intentional and unintentional cyber-attacks pose operational and information security risks, the occurrence of which can negatively impact an investment in the Trust.

RISK FACTORS

You should consider carefully the risks described below before making an investment decision. You should also refer to the other information included in this Prospectus, as well as information found in documents incorporated by reference in this Prospectus, before you decide to purchase any Shares. These risk factors may be amended, supplemented or superseded from time to time by risk factors contained in any periodic report, prospectus supplement, post-effective amendment or in other reports filed with the SEC in the future. See “Glossary of Defined Terms” for an explanation of certain industry and technical terms used in this Prospectus.

Risks Associated with SOL and the Solana Network

The value of the Shares relates directly to the price of SOL, which may be highly volatile and subject to fluctuations due to a number of factors.

The value of the Shares relates directly to the value of the SOL held by the Trust and fluctuations in the price of SOL could adversely affect the value of the Shares. The market price of SOL may be highly volatile, and subject to a number of factors, including:

an increase in the SOL supply that is publicly available for trading;

manipulative trading activity on digital asset trading platforms, which, in many cases, are largely unregulated or may not be complying with existing regulations;

the adoption of SOL as a medium of exchange, store-of-value or other consumptive asset and the maintenance and development of the open-source software protocol of the Solana blockchain;

forks or clones in the Solana blockchain;

falling demand for SOL, or demand that does not keep pace with gradual unlocking of SOL;

delays or flaws in the execution of the Solana blockchain expansion or adoption plans for SOL;

the failure of one or more of SOL strategic partnerships with one or more institutional players;

the failure of, or perceptions of risk or negative publicity around one or more of the protocols based on the Solana blockchain or that make use of SOL;

investors’ expectations with respect to interest rates and rates of inflation experienced by fiat currencies or digital assets (including, in particular, SOL);

consumer preferences and perceptions of SOL specifically and digital assets generally;

fiat currency withdrawal and deposit policies on digital asset trading platforms;

the liquidity of digital asset trading platforms and any increase or decrease in trading volume on digital asset trading platforms;

investment and trading activities of large investors that invest directly or indirectly in SOL;

a “short squeeze” resulting from speculation on the price of SOL, if aggregate short exposure exceeds the number of Shares available for purchase;

a final determination that SOL is offered or sold as a security or changes in SOL’s status under the federal securities laws;

monetary policies of governments, trade restrictions, currency devaluations and revaluations and regulatory measures or enforcement actions, if any, that restrict the use of SOL or the purchase of SOL on digital asset trading platforms;

global or regional political, economic or financial conditions, events and situations;

fees associated with processing a SOL transaction and the speed at which transactions are settled on the Solana blockchain;

interruptions in service from or closures or failures of major digital asset trading platforms;

decreased confidence in digital asset trading platforms due to the unregulated nature and lack of transparency surrounding the operations of digital asset trading platforms;

smart contracts are new and their ongoing development and operation may result in problems or be subject to errors or hacks;

increased competition from other digital assets or other forms of blockchain-based services; and

the Trust’s own acquisitions or dispositions of SOL, since there is no limit on the number of SOL that the Trust may acquire.

In addition, there is no assurance that SOL will maintain its value in the long or intermediate term. In the event that the price of SOL declines, the Delegated Sponsor expects the value of the Shares to decline proportionately. The value of SOL as represented by the Pricing Benchmark or by the Trust’s principal market may also be subject to momentum pricing due to speculation regarding future appreciation in value, leading to greater volatility that could adversely affect the value of the Shares. Momentum pricing typically is associated with growth stocks and other assets whose valuation, as determined by the investing public, accounts for future appreciation in value, if any. The Delegated Sponsor believes that momentum pricing of SOL has resulted, and may continue to result, in speculation regarding future appreciation in the price of SOL, inflating and making the price of SOL more volatile. As a result, SOL may be more likely to fluctuate in value due to changing investor confidence, which could impact future appreciation or depreciation in the Pricing Benchmark and could adversely affect the value of the Shares.

SOL is a relatively new technological innovation with a limited operating history.

SOL has a relatively limited history of existence and operations compared to traditional commodities. There is a limited established performance record for the price of SOL and, in turn, a limited basis for evaluating an investment in SOL. Although past performance is not necessarily indicative of future results, if SOL had a more established history, such history might (or might not) provide investors with more information on which to evaluate an investment in the Trust.

SOL and Solana generally.

SOL is the native digital asset and unit of account on the Solana network. The market value of SOL is not related to any specific company, government or asset. The valuation of SOL depends on a number of factors, including future expectations for the value of the Solana network, the number of SOL transactions, and the overall usage of SOL as an asset. This means that a significant amount of the value of SOL is speculative, which could lead to increased volatility. Investors could experience significant gains, losses and/or volatility in the Trust’s holdings, depending on the valuation of SOL.

Several factors may affect the price of SOL, including, but not limited to: supply and demand, investors’ expectations with respect to the rate of inflation, interest rates, currency exchange rates or future regulatory measures (if any) that restrict the trading of SOL or the use of SOL as a form of payment. The issuance of SOL is determined by a computer code, not by a central bank, and prices can be extremely volatile. For example, between January 1, 2025 and December 31, 2025, the price of SOL ranged from $294.33 to $113.19, marking a drawdown of 61.54%. Likewise, during the first six months of calendar year 2026, the price of SOL ranged from $60.12 to $148.22.There is no assurance that SOL will maintain its long-term value in terms of purchasing power in the future, or that acceptance of SOL payments by mainstream retail merchants and commercial businesses will continue to grow. The value of the Trust’s investments in SOL could decline rapidly, including to zero.

The Solana network is an open-source project without a controlling issuer or administrator of software development. Development of the Solana network is largely overseen by the Solana Foundation, a Swiss non-profit organization, and Solana Labs, Inc., a Delaware corporation, which administered the original network launch and digital asset distribution. Solana Labs and the Solana Foundation continue to exert significant influence over the direction of the development of Solana, however, since the source code for the Solana network is open-source, anyone can contribute to its development. Further, the Solana network does not require governmental authorities or financial institution intermediaries to create, transmit or determine the value of SOL.

As a result, core developers contribute their time and propose upgrades and improvements to the Solana network protocols and various software implementations thereof, often on the Solana repository on the website Github. Core developers’ roles evolve over time, largely based on self-determined participation. Although some market participants such as the Solana Foundation sponsor some developers, core developers are not generally compensated for their work on the Solana network, and such developers may cease to provide services or migrate to alternate digital asset networks. In addition, a lack of resources may result in an inability of the Solana network community to address novel technical issues or to achieve consensus around solutions therefor. As with other digital asset networks, the Solana network faces significant scaling challenges due to the fact that public blockchains generally face a tradeoff between security and scalability. One means through which public blockchains achieve security is decentralization, meaning that no intermediary is responsible for securing and maintaining these systems. For example, a greater degree of decentralization generally means a given digital asset network is less susceptible to manipulation or capture. A digital asset network may be limited in the number of transactions it can process by the capabilities of the participating nodes.

Moreover, in the past, flaws in the source code for digital assets have been exposed and exploited, including flaws that disabled some functionality for users, exposed users’ personal information and/or resulted in the theft of users’ digital assets. The cryptography underlying Solana could prove to be flawed or ineffective, or developments in mathematics and/or technology, including advances in digital computing, algebraic geometry and quantum computing, could result in such cryptography becoming ineffective. In any of these circumstances, a malicious actor may be able to take the Trust’s SOL, which would adversely impact the value of the Shares. Moreover, the functionality of the Solana network may be negatively affected such that it is no longer attractive to users, thereby dampening demand for SOL and the Solana network. Even if another digital asset other than SOL were affected by similar circumstances, any reduction in confidence in the source code or cryptography underlying digital assets generally could negatively affect the demand for digital assets and therefore adversely affect the value of the Shares.

Finally, there can be no assurance that the community as a whole will not implement changes to the Solana network protocols that have an adverse impact on the Trust or an investment in the Shares.

Proof-of-History (PoH) and Proof-of-Stake (PoS) Consensus Mechanisms.

The Solana protocol introduced the PoH timestamping mechanism. PoH automatically orders on-chain transactions by creating a historical record that proves an event has occurred at a specific moment in time. PoH is intended to provide a transaction processing speed and capacity advantage over other blockchain networks like Bitcoin and Ethereum, which rely on sequential production of blocks and can lead to delays caused by validator confirmations. PoH is a new blockchain technology that is not widely used. PoH may not function as intended. For example, it may require more specialized equipment to participate in the network and fail to attract a significant number of users. In addition, there may be flaws in the cryptography underlying PoH, including flaws that affect functionality of the Solana network or make the network vulnerable to attack.

In addition to the PoH mechanism described above, the Solana network uses a proof-of-stake consensus mechanism to incentivize SOL holders to validate transactions. Unlike proof-of-work, in which validators expend computational resources to compete to validate transactions and are rewarded coins in proportion to the amount of computational resources expended, in proof-of-stake, validators “stake” coins to compete to be randomly selected to validate transactions and are rewarded coins in proportion to the amount of coins staked. Any malicious activity, such as disagreeing with the eventual consensus or otherwise violating protocol rules, may result in a reduction of staking rewards for the malicious actor and the “blacklisting” of such malicious actor. Should any of the Trust’s Staking Services Providers engage in malicious activity or perform poorly, then such Staking Services Providers may be blacklisted which could negatively impact the Trust’s abilities to engage in Staking Activities and/or otherwise result in the Trust earning reduced staking rewards. Proof-of-stake is viewed as more energy efficient and scalable than proof-of-work and is sometimes referred to as “virtual mining.”

Staking introduces a risk of loss of SOL, which could adversely affect the value of the Shares.

Staking introduces a risk of loss of SOL. None of the Trust’s assets, including potentially staked assets, are subject to the protections enjoyed by depositors or customers of institutions with FDIC or Securities Investor Protection Corporation membership. Staking requires parties to stake accounts on the Solana network and delegate the SOL to the validator, and un-staking requires the parties to deactivate those stake accounts and transfer the staked assets back. These transfers and delegations could be executed incorrectly or be subject to errors, hacks, cybersecurity vulnerabilities, software defects, outages, bugs, or other failures, any of which could cause the loss of the Trust's staked assets.

A validator may face penalties if it fails to take certain actions, such as providing timely votes during an epoch. Under normal network conditions, inactivity penalties result in a reduction of the validator's staking rewards in an amount generally similar to the rewards the validator would have earned had it performed those duties. If a validator is offline or otherwise fails to participate in consensus for an extended period, the Solana network may reduce the rewards attributable to that validator and the delegators staking with it. Should any of the Trust's Staking Services Providers experience extended downtime or otherwise fail to perform required protocol duties, the Trust's staking rewards may be reduced or eliminated for the affected period.

A more severe sanction (i.e., “slashing”) is imposed if a validator commits malicious acts related to the proposal or attestation of blocks with invalid transactions. On the Solana network, slashing generally operates by social consensus, rather than being automatically hardwired into the protocol’s code. The Solana community generally aspires to slash 100% of staked assets in cases where a Solana node is maliciously trying to violate safety rules and 0% during routine operation. However, to date, no validators on Solana have been subject to such communitarian slashing, although there has been at least one occasion when the Solana Foundation voluntarily burned millions of SOL from its own allocation in response to community concerns about undisclosed token loans to market makers. While not a formal slashing event, the burn functioned as a self-imposed penalty aimed at restoring trust. It is expected that the Solana network will, in future, implement a more programmatic form of slashing, enforced directly on-chain following the generation and submission of a cryptographic proof of the infraction. Such programmatic slashing is not yet a feature of the Solana network. If and when programmatic slashing is introduced, the economic impact of large-scale or coordinated slashing events could be significantly greater than that of isolated incidents, reflecting the greater risk such events pose to network security. There can be no guarantee that slashing, inactivity penalties, and resulting losses will not occur as a result of the Staking Activities, if they are undertaken.

There can be no guarantee that penalties, and the resulting losses will not occur as a result of the Staking Activities, if they are undertaken. Furthermore, a Staking Services Provider's liability to the Trust is limited, and a Staking Services Provider may lack the assets or insurance in order to support the recovery of any losses incurred. There can be no guarantee that the Trust would recover any of its staked assets, or the value thereof, if it is subject to sanctions imposed by the Solana network. In addition, even where a Staking Services Provider is contractually obligated to compensate the Trust for losses resulting from slashing events attributable to the validator's failure to perform its obligations, such compensation is subject to conditions, exclusions, evidentiary requirements, and timing delays, may not apply to protocol-wide events or software failures, and may not fully offset the Trust's losses.

Staked SOL will be inaccessible for a variable period of time, determined by a range of factors, which could result in certain liquidity risk to the Trust.

The Delegated Sponsor may, from time to time, stake a portion of the Trust’s SOL on behalf of the Trust through one or more Staking Services Providers. Under current Solana network protocols, staked SOL tokens are permitted to be un-staked by the holder of such SOL tokens. However, as part of the “activating” and “exiting” processes of staking, staked SOL tokens will be inaccessible for a variable period of time determined by a range of factors, including network congestion, resulting in certain liquidity risks that the Delegated Sponsor plans to manage.

“Activation” is the funding of a validator to be included in the active set, thereby allowing the validator to participate in the Solana network’s proof-of-stake consensus protocol. “Exit” is the request to exit from the active set and no longer participate in the Solana network’s proof-of-stake consensus protocol. As part of these “activating” and “exiting” processes of staking on the Solana network, any staked SOL will be inaccessible for a period of time. The duration of activating and exiting periods are dependent on a range of factors, including network conditions. However, depending on demand, un-staking can take between hours or days to complete. This can result in certain liquidity risk to the Trust, which the Delegated Sponsor will seek to manage through a range of risk management methods.

There is a risk that the Trust could become unable to timely meet excessive redemption requests in amounts that are greater than the portion of the Trust’s SOL that remains un-staked, leading to temporary delays in settlement and, in extreme scenarios, the temporary unavailability of the Trust’s redemption program. Moreover, any staked SOL which must be un-staked in order to fulfill a redemption (to the extent such redemption cannot be fulfilled utilizing the portion of the Trust’s SOL that has not been staked) will be un-staked only after the redemption request is approved by the Trust, the Staking Services Provider executes an un-stake or withdrawal transaction, and such transaction is processed by the Solana network. The Staking Services Provider will not be able to change the addresses on the Solana network to which staked SOL is to be withdrawn or to which SOL rewards shall be sent.

The Trust will be dependent on third parties to effectively execute the Trust’s Staking Activities.

The amount of staking rewards that the Trust’s staking activity will generate will be dependent on the performance of the Staking Services Providers, including the adequacy and reliability of the hardware and software utilized by the Staking Services Providers. If the Staking Services Providers experience service outages or otherwise are unable to optimally execute the staking of the Trust’s SOL, the Trust’s staking rewards may be adversely affected.

The Trust will not stake its SOL if the Delegated Sponsor has determined in its sole discretion that the Trust may not do so without undue legal or regulatory risk, such as, without limitation, the risk of jeopardizing the Trust’s ability to qualify as a grantor trust for tax purposes, which could harm the value of the Shares.

The Trust’s investment objective is to seek to track the performance of SOL, as measured by the performance of the Pricing Benchmark adjusted for the Trust’s expenses and other liabilities, and to reflect rewards from staking a portion of the Trust’s SOL. If the Delegated Sponsor determines that the Trust is not able to so carry out Staking Activities, the Trust may cease some or all of its Staking Activities. Staking on the Solana network involves delegating SOL to validators and carries risks discussed further below. Staked SOL may be subject to community-determined penalties for validator misbehavior, or slashing. If a Staking Service Provider causes the Trust’s staked SOL to be subject to such slashing losses, the Trust could suffer losses of the staked SOL. Additionally, the staking process includes protocol-defined warm-up, activation and withdrawal periods, during which staked SOL is temporarily locked and inaccessible. These phases affect when SOL begins earning rewards, participates in consensus and becomes available for transfer or redelegation.

The Staking Services Providers will stake the Trust’s SOL as the node operator and will operate a validator node to stake the Trust’s SOL. The Staking Services Providers will perform their staking services in collaboration with the SOL Custodians, as the SOL will be staked directly from the Trust’s SOL Accounts with the SOL Custodians. The Trust will maintain control of the SOL while it is staked because it will remain in the Trust’s account with the SOL Custodians (i.e., it will be kept in a separate account for which the Trust is the beneficial and record owner and will not be commingled with other parties’ accounts with the SOL Custodians). Staking will be a passive activity for the Trust, as it will not operate its own Staking Activities. The Delegated Sponsor’s role with respect to staking will be limited to evaluating and approving one or more Staking Services Providers and instructing the relevant SOL Custodian on when to stake and/or un-stake the Trust’s SOL; the Trust will not contract directly with any Staking Services Provider, and all staking arrangements with Staking Services Providers will be entered into by the SOL Custodian.

The Trust may be negatively impacted by Staking Activities.

The Solana network uses a proof-of-stake consensus mechanism, enhanced by proof-of-history, to secure and operate the network, meaning that the voting power of a validator in the network is determined by the amount of stake delegated to them by SOL token holders. The more stake delegated to a validator, the more voting power they have, the higher the likelihood is that the validator will be selected to propose and validate blocks and the higher the associated reward will be. This, in turn, leads to higher SOL earnings for the SOL tokenholders who chose to stake with the validator in question.

If a SOL tokenholder chooses to engage in staking, they must either choose a specific validator to stake with or have sufficient SOL to be selected as a validator by the Solana network themselves and also have the necessary hardware to run the validator. The choice of validator can potentially impact the amount of staking rewards the tokenholder receives. The factors determining this amount include, but are not limited to:

Validator commission rate: a validator can choose to set a non-zero commission rate specifying the percentage of staking rewards they are taking from the stakers. For example, if a validator has a commission rate of 10%, then 10% of such staker’s staking rewards are given to the validator.

Validator performance: a validator with bad performance during an epoch will receive reduced staking rewards for the applicable epoch, and SOL tokenholders who have delegated their stake to such validator will also receive reduced rewards for such epoch when they withdraw their stake from such validator.

If any Staking Services Provider experiences operational or other difficulties, terminates their services, fails to comply with regulations, raises their prices or disputes key intellectual property rights sold or licensed to, the Trust, the Trust could suffer losses. The Trust may also suffer the consequences of such Staking Services Provider’s mistakes. For example, if the Trust’s SOL Custodians or Staking Services Provider selected to act as validators fail to behave as expected, default, fail to perform, suffer cybersecurity attacks, experience security issues or encounter other problems, the assets of the Trust may be irretrievably lost. The failure or capacity restraints of vendors and services, a cybersecurity breach involving any service providers or the termination or change in terms or price or commission rate of a vendor, third-party software license or service agreement on which the Trust relies, could disrupt the Trust’s Staking Activities or cause losses. Replacing any Staking Services Provider or addressing other issues with vendors and service providers could entail significant delay, expense and disruption for the Trust. As a result, if these vendors and service providers experience difficulties, are subject to cybersecurity breaches, terminate their services, dispute the terms of intellectual property agreements or raise their prices, and the Delegated Sponsor is unable to replace them with other vendors and service providers, particularly on a timely basis, the Trust’s Staking Activities could be interrupted or disrupted, and the Trust could suffer a loss.

The Solana network dictates requirements for participation in the network’s protocols and may reduce rewards if the relevant activities are not performed correctly. Malicious or poorly performing validators may also be “blacklisted,” meaning that SOL tokenholders may decide to no longer delegate stake to such actors thereby resulting in such actors not being selected to validate and they would therefore be unable to receive staking rewards therefrom. Should any of the Trust’s Staking Services Providers engage in malicious activity or perform poorly, then such Staking Services Providers may be blacklisted which could negatively impact the Trust’s abilities to engage in Staking Activities and/or otherwise result in the Trust earning reduced staking rewards.

Staking requires that the Trust lock up the staked SOL and become subject to an unbonding period to un-stake the staked SOL, meaning that the Trust cannot transfer the staked SOL during the time that the SOL is staked and during which it is being unbonded. The historical average unbonding period for staked SOL was 2-4 days, with the epoch length decreasing over the last year to approximately 2 days for the one-year period ended May 31, 2026. However, the unbonding period also may be longer than anticipated based on network activity.

Due to the time involved in “exiting” the staking process, there is a risk that the Trust could become unable to timely meet excessive redemption requests in amounts that are greater than the portion of the Trust’s SOL that remains un-staked, leading to temporary delays in settlement and, in extreme scenarios, the temporary unavailability of the Trust’s redemption program. Moreover, any staked SOL which must be un-staked in order to fulfill a redemption (to the extent such redemption cannot be fulfilled utilizing the portion of the Trust’s SOL that has not been staked, or through another mechanism to manage liquidity in connection with Redemption Orders) will be un-staked only after the redemption request is approved by the Delegated Sponsor, the Delegated Sponsor executes an un-stake or withdrawal transaction through the SOL Custodians, and such transaction is processed by the Solana network. The Staking Services Provider will not be able to transfer un-staked SOL or Staking Provider Consideration to another address on the Solana network.

There is no guarantee that the Trust will receive any rewards with respect to staked SOL. Past rewards are not indicative of future rewards. The staking rewards that the Trust may receive from staking SOL, if any, may be affected by, among other factors:
