Zcash ETF: adds Anchorage Digital as additional custodian

What happened

• The filing states that on Sep 29, 2026, Grayscale Investments Sponsors, LLC, sponsor of The Zcash ETF (the Trust), entered into the 6th amendment to the Master Custody Service Agreement with Anchorage Digital Bank N.A., pursuant to which the Trust became a party to the Anchorage Digital Custodian Agreement and Anchorage Digital will provide custody and safekeeping services for a portion of the Trust’s ZEC holdings. The original Master Custody Service Agreement is dated Aug 8, 2025.

Key details

• At the current time, the Sponsor has not determined the total amount of the Trust’s ZEC it will move to Anchorage Digital.
• The Trust’s existing custody arrangement with Coinbase Custody Trust Company, LLC is unaffected; Coinbase remains the Trust’s primary custodian. The Sponsor will determine, in its sole discretion, the amounts held at either custodian.
• Fees paid to the additional custodian are a Sponsor-paid Expense. Anchorage Digital generates and retains the private keys for the Trust’s ZEC and stores those keys in a hardware security module located in the United States.
• Anchorage Digital may temporarily suspend services in the event of a fork and may decide whether to support or cease supporting either branch; Anchorage Digital is required to maintain certain insurance coverage, including commercial crime insurance or a fidelity bond with limits of not less than $100,000,000 in the aggregate.
