Item 1.01 Entry into a Material Definitive Agreement.

On December 16, 2025, 21Shares Solana ETF (the “Trust”) entered into a new authorized participant agreement (the “Authorized Participant Agreement”) with Macquarie Capital (USA) Inc. (“Macquarie”), pursuant to which Macquarie has agreed to act as an authorized participant of the Trust. The Authorized Participant Agreement provides the procedures for the creation and redemption of blocks of 10,000 shares (“Baskets”) and for the delivery of the solana required for such creation and redemption. The Authorized Participant Agreement differs from the Trust’s agreements with other authorized participants in that it allows for in-kind creation and redemption orders. In connection with each order by Macquarie to create or redeem one or more Baskets, unless waived by the sponsor of the Trust, 21Shares US LLC (the “Sponsor”), the Sponsor shall charge a transaction fee. The Authorized Participant Agreement may be amended as mutually agreed by the parties, without the consent of any shareholder of the Trust (“Shareholder”). The procedures governing the order entry system may be amended by the Trust without the consent of Macquarie or any Shareholder. The Authorized Participant Agreement requires the Trust to indemnify Macquarie and certain of its affiliates in certain situations, including against certain losses arising or related to untrue or alleged untrue statements of material fact under the Registration Statement and Prospectus (as defined therein), breach of the Authorized Participant Agreement or violation of applicable law. The Authorized Participant Agreement continues indefinitely, unless earlier terminated in accordance with its terms.

The foregoing description is a summary, and does not purport to be a complete description, of the Authorized Participant Agreement, and is qualified in its entirety by reference to the Form of Master Authorized Participant Agreement, which is filed as Exhibit 10.1 hereto and is incorporated by reference herein.

Item 8.01 Other Events.

Beginning in 2026, the Trust intends to pay cash distributions at least quarterly to Shareholders to distribute staking rewards earned 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 solana held by the Trust, the percentage of the Trust’s solana 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 Trust will notify shareholders of the timing of any distributions via press release.

Item 9.01 Financial Statements and Exhibits.
