Item 1.01. Entry into a Material Definitive Agreement.

Prime Broker Agreement

On October 3, 2025, Grayscale Investments Sponsors, LLC, the sponsor (the “Sponsor”), on behalf of itself and Grayscale Stellar Lumens Trust (XLM) (the “Trust”), and Coinbase, Inc., the prime broker of the Trust (“Coinbase” or the “Prime Broker”), on behalf of itself and as agent for Coinbase Custody Trust Company, LLC (“Coinbase Custody” or the “Custodian”) and Coinbase Credit, Inc. (“Coinbase Credit” and, collectively with Coinbase and Coinbase Custody, the “Coinbase Entities”), entered into the Coinbase Prime Broker Agreement, which includes the Coinbase Custody Custodial Services Agreement attached thereto as Exhibit A (the “CSA”), the Coinbase Settlement and Transfer Agreement attached thereto as Exhibit B (the “STA”) and all other exhibits, addenda and supplements attached thereto (collectively with the CSA and STA, the “Prime Broker Agreement”) governing the Trust’s and the Sponsor’s use of the custodial and prime broker services provided by the Custodian and the Prime Broker. The Prime Broker Agreement establishes the rights and responsibilities of the Custodian, the Prime Broker, the Sponsor and the Trust with respect to the Trust’s XLM which is held in accounts maintained and operated by the Custodian, as a fiduciary with respect to the Trust’s assets, and the Prime Broker (together with the Custodian, the “Custodial Entities”) on behalf of the Trust.

Although executed as of October 3, 2025, the Prime Broker Agreement shall not become effective with respect to the Trust until the date on which the shares of the Trust begin trading on NYSE Arca as shares of an exchange-traded product (the “Uplisting Date”).

Coinbase Custody is currently the custodian of the Trust and is party to the Previous Custodian Agreement (as defined in Item 1.02 below).

The foregoing description, together with the below description of certain terms of the Prime Broker Agreement, is a summary, does not purport to be a complete description of the Prime Broker Agreement, and is qualified in its entirety by reference to the full text of the Prime Broker Agreement, a copy of which is filed as Exhibit 10.1 hereto and is incorporated by reference herein. In addition, the risk factors related to the Prime Broker Agreement set forth in Exhibit 99.1 hereto update the Trust’s previously filed risk factors to the extent applicable and are incorporated by reference herein.

Accounts; Location of Digital Assets

All of the Trust’s XLM, other than that which is credited to a settlement balance maintained with the Prime Broker (the “Settlement Balance”), is held in custody accounts maintained on the books of the Custodian, as to which the Custodian controls the private keys which allow for the transfer of ownership or control of the Trust’s XLM on the Trust’s behalf (the “Vault Balance”). The Prime Broker Agreement provides that the Trust’s Vault Balance will be held by the Custodian in segregated wallets or accounts. The Custodian will keep all of the private keys associated with the Trust’s XLM held in the Vault Balance in an offline manner. The term “cold storage” refers to a safeguarding method where the storage of private keys may involve keeping such keys’ materials on a non-networked computer or electronic device or storing the private keys on a storage device. Cold storage is a safeguarding method with multiple layers of protections and protocols, by which the private keys corresponding to the Trust’s XLM are generated and stored in an offline manner. The term “hot storage” refers to the safeguarding method by which the private keys are held online, where they are more accessible, leading to more efficient transfers, though they are potentially more vulnerable to theft, loss or damage.

Additionally, at the Sponsor’s discretion, a portion of the Trust’s XLM holdings may be credited to the Settlement Balance, which will be reflected in a ledger maintained on the books of the Prime Broker. The Prime Broker Agreement provides that any XLM credited to the Trust’s Settlement Balance will be held (i) in omnibus cold storage wallets; (ii) in omnibus hot storage wallets; or (iii) in omnibus accounts with one of the third-party venues to which Coinbase has established connections (each, a “Coinbase Connected Venue”). The Settlement Balance shall be separate from the Vault Balance and any other account(s) the Trust or the Sponsor maintain with the Custodian. From time to time, the Prime Broker may temporarily keep a portion of the private keys associated with the XLM credited to the Trust’s Settlement Account in hot storage for purposes of facilitating the receipt and distribution of XLM in connection with the creation and redemption of Baskets.

Private key shards associated with the Trust’s XLM are distributed geographically by the Custodial Entities in secure vaults around the world, including in the United States. The locations of the secure vaults may change and are kept confidential by the Custodian for security purposes.

The Prime Broker Agreement states that the Custodian serves as a fiduciary and custodian on the Trust’s behalf with respect to the Trust’s XLM held in the Vault Balance and the XLM in the Vault Balance are considered fiduciary assets that remain the Trust’s property at all times and are not treated as general assets of the Custodian. Under the Prime Broker Agreement, the Custodian represents and warrants that it has no right, interest, or title in the XLM in the Trust’s Vault Balance, and agrees that it will not, directly or indirectly, lend, pledge, hypothecate or rehypothecate such digital assets. The Custodian does not reflect such digital assets as assets on the balance sheet of the Custodian, but does reflect the obligation to safeguard such digital assets with a corresponding asset measured at fair value for such obligation. With respect to the Trust’s XLM credited to the Settlement Balance, the Prime Broker maintains an internal ledger

that specifies the XLM credited to the Trust’s Settlement Balance. The Prime Broker Agreement states that the Prime Broker treats such XLM as custodial assets held for the benefit of the Trust, and shall not be considered the property of the Prime Broker. Additionally, under the Prime Broker Agreement, the Prime Broker represents and warrants that it will not, directly or indirectly, sell, transfer, loan, rehypothecate or otherwise alienate the Trust’s XLM credited to the Settlement Balance.

The Custody Agreement also contains an agreement by the parties to treat the digital assets credited to the Trust’s Vault Balance and Settlement Balance as “financial assets” under Article 8 of the New York Uniform Commercial Code (“Article 8”) and to treat the Vault Balance and Settlement Balance as “securities accounts” with respect to which the Trust is the “entitlement holder” within the meaning of Article 8. The Custodial Entities’ ultimate parent, Coinbase Global, Inc. (“Coinbase Global”), has stated in its public securities filings that in light of the inclusion in its custody agreements of provisions relating to Article 8 it believes that a court would not treat custodied digital assets as part of its general estate, although due to the novelty of digital assets courts have not yet considered this type of treatment for custodied digital assets. See “Risk Factors—The Trust relies on third-party service providers to perform certain functions essential to the affairs of the Trust and the replacement of such service providers could pose challenges to the safekeeping of the Trust’s XLM and to the operations of the Trust” in Exhibit 99.1 hereto for more information.

Safekeeping of XLM

The Custodian will use commercially reasonable efforts to keep in safe custody on behalf of the Trust all XLM received by the Custodian. All XLM credited to the Vault Balance will (i) be held in the Vault Balance at all times, and the Vault Balance will be controlled by the Custodian; (ii) be labeled or otherwise appropriately identified as being held for the Trust; (iii) be held on a non-fungible basis; (iv) not be commingled with other digital assets held by the Custodian, whether held for the Custodian’s own account or the account of other clients other than the Trust; and (v) not without the prior written consent of the Trust be deposited or held with any third-party depositary, custodian, clearance system or wallet. Additionally, the Custodian will use commercially reasonable efforts to keep the private key or keys for the Vault Balance secure, and will not disclose such keys to the Trust, the Sponsor or to any other individual or entity except to the extent that any keys are disclosed consistent with a standard of commercially reasonable efforts and as part of a multiple signature solution that would not result in the Trust or the Sponsor “storing, holding, or maintaining custody or control of” the XLM “on behalf of others” within the meaning of the New York BitLicense Rule (23 NYCRR Part 200) as in effect as of June 24, 2015 such that it would require the Trust or the Sponsor to become licensed under such law.

XLM credited to the Trust’s Settlement Balance may be held in omnibus wallets maintained by the Prime Broker and/or at Coinbase Connected Venues. While the XLM credited to the Trust’s Settlement Balance could be commingled with other assets, the XLM in the Trust’s Settlement Balance will represent entitlement to a pro-rata share of the XLM held in such omnibus wallets and/or at Coinbase Connected Venues. In all circumstances the Prime Broker will keep an internal ledger that specifies the assets credited to the Settlement Balance such that the Trust, its auditors and regulators can identify the Trust’s pro-rata share of the XLM held in omnibus wallets and/or at Coinbase Connected Venues. Neither the Trust nor the Sponsor have a contractual relationship with the Coinbase Connected Venues utilized by the Custodial Entities.

Insurance

Pursuant to the terms of the Prime Broker Agreement, the Custodian is required to maintain insurance in such types and amounts as are commercially reasonable for the custodial services it provides. The Custodian has advised the Sponsor that it has insurance coverage pursuant to policies held by Coinbase Global, which procures fidelity (or crime) insurance coverage at commercially reasonable amounts for the custodial services provided. This insurance coverage is limited to losses of the digital assets the Custodian custodies on behalf of its clients, including the Trust’s XLM, resulting from theft, including internal theft by employees of Coinbase and its subsidiaries and theft or fraud by a director of Coinbase if the director is acting in the capacity of an employee of Coinbase or its subsidiaries.

Although the Prime Broker is not required to maintain insurance under the terms of the Prime Broker Agreement, the Custodial Entities have also advised the Sponsor that they maintain insurance coverage pursuant to such policies held by Coinbase Global.

Moreover, while the Custodian maintains certain capital reserve requirements depending on the assets under custody and to the extent required by applicable law, and such capital reserves may provide additional means to cover client asset losses, the Sponsor does not know the amount of such capital reserves, and neither the Trust nor the Sponsor have access to such information. The Trust cannot be assured that the Custodian will maintain capital reserves sufficient to cover losses with respect to the Trust’s digital assets. Furthermore, Coinbase has represented in securities filings that the total value of crypto assets in its possession and control is significantly greater than the total value of insurance coverage that would compensate Coinbase in the event of theft or other loss of funds.

Deposits, Withdrawals and Storage

The Custodian and the Prime Broker provide for: (i) holding of the Trust’s XLM in the Vault Balance and the Settlement Balance; (ii) transfer of the Trust’s XLM between the relevant Vault Balance and the Settlement Balance; (iii) the deposit of XLM from a public blockchain address into the respective account or accounts in which the Vault Balance or the Settlement Balance are maintained; and (iv) the withdrawal of XLM from the Vault Balance to a public blockchain address the Trust controls (each such transaction is a “Custody Transaction”) (collectively, the “Custodial and Prime Broker Services”).

The Custodian reserves the right to refuse to process or to cancel any pending Custody Transaction as required by law or in response to a subpoena, court order, or other binding government order or to enforce transaction, threshold, and condition limits, in each case as communicated to the Trust as soon as reasonably practicable where the Custodian is permitted to do so, or if the Custodian reasonably believes that the Custody Transaction may violate or facilitate the violation of an applicable law, regulation or applicable rule of a governmental authority or self-regulatory organization. The Custodial Entities may suspend, restrict or terminate the Trust’s and the Sponsor’s access to the Custodial and Prime Broker Services, and/or suspend, restrict or close the accounts associated with the Trust’s Vault Balance and Settlement Balance (the “Accounts”) if the Trust or Sponsor has taken certain actions, including any prohibited use or prohibited business as set forth in the Prime Broker Agreement or if either or both of the Custodial Entities are required to do so by a subpoena, court order, or other binding government order.

From the time the Custodian has verified the authorization of a complete set of instructions to withdraw XLM from the Vault Balance, the Custodian will have a limited amount of time to process and complete such withdrawal. The Custodian will ensure that initiated deposits are processed in a timely manner but the Custodian makes no representations or warranties regarding the amount of time needed to complete processing which is dependent upon many factors outside of the Custodian’s control. Transactions relating to XLM held in the Settlement Balance occur on the relevant digital asset protocols.

The Custodial Entities make no other representations or warranties with respect to the availability and/or accessibility of XLM or the availability and/or accessibility of the Vault Balance, the Settlement Balance or the Custodial and Prime Broker Services.

Security of the Accounts

The Custodial Entities securely store all digital asset private keys held by the Custodian on secure servers or offline, in cold storage. Under the Prime Broker Agreement, the Custodian must use commercially reasonable efforts to keep the private key or keys to the Vault Balance secure, and may not disclose such private keys to the Sponsor, Trust or any other individual or entity.

The Custodial Entities have implemented and will maintain reasonable information security programs that include policies and procedures that are reasonably designed to safeguard the Custodial Entities’ electronic systems and the Trust’s and the Sponsor’s confidential information from, among other things, unauthorized access or misuse. In the event of a Data Security Event (as defined in the Prime Broker Agreement), the Custodial Entities will promptly (subject to any legal or regulatory requirements) notify the Trust and the Sponsor.

Key Generation

Public addresses and their corresponding private keys are generated by the Custodian, as applicable in secret key generation ceremonies at secure locations inside faraday cages, which are enclosures used to block electromagnetic fields and thus mitigate against attacks. The Custodian uses quantum random number generators to generate the public and private key pairs.

Once generated, private keys are encrypted, separated into “shards”, and then further encrypted. After the key generation ceremony, all materials used to generate private keys, including computers, are destroyed. All key generation ceremonies are performed offline. No party other than the Custodian has access to the private key shards of the Trust.

Key Storage

Private key shards are distributed geographically by the Custodial Entities in secure vaults around the world, including in the United States. The locations of the secure vaults may change and are kept confidential by the Custodian and the Prime Broker for security purposes.

The Vault Balance primarily uses “cold” storage mechanisms to secure a substantial portion of the Trust’s private keys. A substantial portion of the Trust’s XLM holdings will be held in cold storage at all times, with a portion of the Settlement Balance held temporarily in hot storage from time to time, for purposes of facilitating the receipt and distribution of XLM in connection with the creation and redemption of Baskets. Any XLM credited to the Trust’s Settlement Balance is stored in omnibus accounts, either on the Prime Broker’s systems or at Coinbase Connected Venues, using a combination of cold and hot storage mechanisms to secure the private keys representing the assets credited to the Trust’s Settlement Balance.

The term cold storage refers to a safeguarding method where the storage of private keys may involve keeping such keys’ materials on a non-networked computer or electronic device or storing the private keys on a storage device. Cold storage is a safeguarding method with multiple layers of protections and protocols, by which the private keys corresponding to the Trust’s XLM are generated and stored in an offline manner. A digital wallet may receive deposits of digital assets but may not send digital assets without use of the digital assets’ corresponding private keys. In order to send digital assets from a digital wallet in which the private keys are kept in cold storage, either the private keys must be retrieved from cold storage and entered into an online, or hot, digital asset software program to sign the transaction, or the unsigned transaction must be transferred to the cold server in which the private keys are held for signature by the private keys and then transferred back to the online digital asset software program. At that point, the user of the digital wallet can transfer its digital assets. While private keys held in hot storage are more accessible and therefore enable more efficient transfers, such assets are more vulnerable to theft, loss or damage.

Security Procedures

The Custodian and the Prime Broker hold the Trust’s private keys in custody in accordance with the terms and provisions of the Prime Broker Agreement. Transfers to and from the Vault Balance and, where held in cold storage, the Trust’s Settlement Balance, require certain security procedures, including but not limited to, multiple encrypted private key shards, usernames, passwords and 2-step verification. Multiple private key shards held by the applicable Custodial Entity or Entities must be combined to reconstitute the private key to sign any transaction in order to transfer the Trust’s assets. Private key shards are distributed geographically by the Custodial Entities in secure vaults around the world, including in the United States.

As a result, if any one secure vault is ever compromised, this event will have no impact on the ability of the Trust to access its assets, other than a possible delay in operations, while one or more of the other secure vaults is used instead. These security procedures are intended to remove single points of failure in the protection of the Trust’s assets.

Transfers of XLM to the Vault Balance from the Settlement Balance will be available to the Trust once processed on the relevant digital asset protocols, subject to the availability of the Prime Broker’s online platform. When XLM is credited to the Settlement Balance, certain movements to allocate the balance among (i) omnibus cold storage wallets and omnibus hot storage wallets on the Prime Broker’s platform; or (ii) omnibus accounts at Coinbase Connected Venues may not be viewable by the Trust via the Prime Broker’s online portal. In addition, on a monthly basis the Custodial Entities will provide the Sponsor with an account statement identifying the amount of cash and XLM in the Trust’s Accounts at the end of the period and listing all account activity during that period.

Record Keeping; Inspection and Auditing

The Custodian will keep timely and accurate records as to the deposit, disbursement, investment and reinvestment of the XLM in the Vault Balance, and such records must be retained by the Custodian for no less than seven years. The Prime Broker Agreement also provides that each Custodial Entity will permit, to the extent it may legally do so, the Trust or the Trust’s third-party representatives, upon thirty days’ notice, to inspect, take extracts from and audit the records that it maintains, take such steps as necessary to verify that satisfactory internal control systems and procedures are in place, as the Trust may reasonably request. The Prime Broker is obligated to notify the Trust of any audit report prepared by its internal or independent auditors if such report reveals any material deficiencies or makes any material objections.

The Trust and the Sponsor obtain and perform a comprehensive review of the Services Organization Controls (“SOC”) 1 report and SOC 2 each year. In addition to the review of SOC 1 and SOC 2 reports, the Trust, the Sponsor and/or their respective auditors may inspect or audit the Custodian’s records in a variety of manners if considered necessary. Such processes, may include validating the existing balances as reflected on the Custodian’s user interface to nodes of the underlying blockchain and confirming that such digital assets are associated with its public keys to validate the existence and exclusive ownership of the digital assets. To validate software functionality of the private keys, the Trust may transfer a portion of its digital assets from one public key to another public key of the Trust.

The Trust, the Sponsor and their independent auditors may evaluate the Custodian’s protection of private keys and other customer information, including review of supporting documentation related to the processes surrounding key lifecycle management, the key generation process (hardware, software, and algorithms associated with generation) the infrastructure used to generate and store private keys, how private keys are stored (for example, cold wallets), the segregation of duties in the authorization of digital asset transactions, and the number of users required to process a transaction and the monitoring of addresses for any unauthorized activity.

Once each calendar year, the Trust and the Sponsor are entitled to request that the Custodial Entities provide a copy of the SOC 1 report and SOC 2 report once per calendar year. Such reports are required to be dated within one year prior to such request. The Custodial Entities reserve the right to combine the SOC 1 and SOC 2 reports into a comprehensive report. In the event that the Custodial Entities do not deliver a SOC 1 Report or SOC 2 Report, as applicable, the Sponsor and the Trust will be entitled to terminate the Prime Broker Agreement. In addition to the review of SOC 1 and SOC 2 reports, the Trust may also request letters of representation on a quarterly basis between SOC reports regarding any known changes or conclusions to the SOC 1 and SOC 2 reports.

Standard of Care; Limitations of Liability

The Custodian will use commercially reasonable efforts to keep in safe custody on behalf of the Trust all XLM received by the Custodian. The Custodial Entities are liable to the Sponsor and the Trust for the loss of any XLM to the extent such loss resulted from the negligence, fraud or willful misconduct of the Custodial Entities. To the extent any loss is caused by a Custodial Entity’s negligence, fraud or willful misconduct, the Custodial Entities are required to return to the Trust a quantity of XLM equal to the quantity of any such lost XLM.

The Custodial Entities’ or Trust’s total liability under the Prime Broker Agreement will not exceed the greater of: (i) the value of the XLM or cash involved in the event, including but not limited to transaction(s) or deliveries(s), giving rise to such liability at the time of the event giving rise to such liability; (ii) the aggregate amount of fees paid by the Trust to the Custodial Entities in respect of the Custody and Prime Broker Services in the 12-month period prior to the event giving rise to such liability; or (iii) five million U.S. dollars. The Custodian’s total liability under the Prime Broker Agreement will not exceed the greater of: (i) the aggregate amount of fees paid by the Trust to the Custodian in respect of the custodial services in the 12-month period prior to the event giving rise to such liability; or (ii) the value of the XLM on deposit in the Vault Balance at the time of the events giving rise to the liability occurred, the value of which will be determined in accordance with the Prime Broker Agreement. In addition, the Custodian’s maximum liability in respect of each cold storage address that holds XLM shall be limited to $100 million (the “Cold Storage Threshold”). The Sponsor monitors the value of XLM deposited in cold storage addresses for whether the Cold Storage Threshold has been met by determining the U.S. dollar value of XLM deposited in each cold storage address on business days. Although the Cold Storage Threshold has to date not been met for a given cold storage address, to the extent it is met the Trust would not have a claim against the Custodian with respect to the digital assets held in such address to the extent the value exceeds the Cold Storage Threshold.

The Custodial Entities and the Trust are not liable to each other for any special, incidental, indirect, punitive, or consequential damages, whether or not the other party had been advised of such losses or knew or should have known of the possibility of such damages. In addition, the Custodial Entities are not liable to the Trust for circumstances resulting from certain force majeure events.

Indemnity

The Trust and the Custodial Entities have agreed to indemnify one another from and against certain claims or losses, subject to customary exceptions and limitations.

Fees and Expenses

The Sponsor will pay an annualized fee to the Coinbase Entities, covering the Trust’s use of the Custodial and Prime Broker Services, that is accrued on a monthly basis as a percentage of the Trust’s monthly assets under custody. The Sponsor will also pay a monthly fee to the Prime Broker, covering withdrawals and deposits to or from the Settlement Balance in connection with the creation and redemption of Shares.

Term; Termination and Suspension

The Prime Broker Agreement will remain in effect until either party terminates the Prime Broker Agreement; provided, however, that the Coinbase Entities shall not restrict, suspend, or modify any Prime Broker Services following termination of the Prime Broker Agreement by a Custodial Entity without Cause (as defined in the Prime Broker Agreement) or by the Trust until the end of the applicable notice period and neither party’s termination of the Prime Broker Agreement will be effective until the Trust and/or the Custodial Entities, as the case may be, have fully satisfied their obligations thereunder.

The Trust may terminate the Prime Broker Agreement in whole or in part upon thirty days’ prior written notice to the applicable Custodial Entity; and (ii) for Custodian Cause (as defined in the Prime Broker Agreement) at any time by written notice to the Prime Broker, effective immediately, or on such later date as may be specified in such notice. The Trust will also be entitled to terminate the Prime Broker Agreement in the event that the Custodial Entities do not deliver a SOC 1 Report or SOC 2 Report, as applicable. See “-Record Keeping; Inspection and Auditing.”

The Custodial Entities may terminate the Prime Broker Agreement (i) upon one hundred eighty days’ prior written notice to the Trust; and (ii) for Cause at any time by written notice to the Trust, effective immediately, or on such later date as may be specified in the notice.

In the event that either the Trust or the Custodial Entities terminate the Prime Broker Agreement without Cause, the Custodial Entities shall use reasonable efforts to assist the Trust with transferring any digital assets, fiat currency or funds associated with the Trust’s Accounts to another custodial services provider within ninety days of receipt of the applicable termination notice.

Governing Law

The Prime Broker Agreement is governed by New York law.

Fund Administration and Accounting Agreement

The Sponsor has engaged BNY Mellon Asset Servicing, a division of The Bank of New York Mellon, a New York corporation authorized to do a banking business (“BNY”), to provide the Trust with certain administrative and accounting services pursuant to the Fund Administration and Accounting Agreement with BNY, which became effective on October 9, 2025 (the “Fund Administration and Accounting Agreement”).

The foregoing description is a summary, does not purport to be a complete description of the Fund Administration and Accounting Agreement, and is qualified in its entirety by reference to the full text of the Fund Administration and Accounting Agreement, a copy of which is filed as Exhibit 10.2 hereto and is incorporated by reference herein.

Item 1.02. Termination of a Material Definitive Agreement.

Previous Custodian Agreement

In connection with the entry into the Prime Broker Agreement, the Sponsor and the Custodian agreed to terminate, as of the Uplisting Date, the Amended and Restated Custodian Agreement, dated June 29, 2022, between the Sponsor and the Custodian (the “Previous Custodian Agreement”).

Under the Previous Custodian Agreement, the Custodian controlled and secured the Trust’s “Digital Asset Account,” a segregated custody account to store private keys, which allow for the transfer of ownership or control of the Trust’s XLM, on the Trust’s behalf. The Custodian’s services (i) allowed XLM to be deposited from a public blockchain address to the Trust’s Digital Asset Account and (ii) allowed the Trust or Sponsor to withdraw XLM from the Trust’s Digital Asset Account to a public blockchain address the Trust or Sponsor controls.
