The information furnished under this Item 7.01, including Exhibit 99.1, shall not be deemed “filed” for purposes of Section 18 of the Exchange Act, or otherwise subject to the liabilities of that section, and shall not be deemed incorporated by reference into any of the Company’s filings under the Securities Act of 1933, as amended, or the Securities Act, or the Exchange Act, whether made before or after the date hereof, regardless of any general incorporation language in such filing, except as shall be expressly set forth by specific reference in such filing.

Item 8.01 - Other Events.

Reliance on Generic Listing Standards and Index Constituents

In reliance on the new generic listing rules adopted by The Nasdaq Stock Market LLC (the “Exchange”) and approved by the U.S. Securities and Exchange Commission (the “SEC”) (SR-NASDAQ-2025-056) (the “generic listing standards”), the Trust will be permitted to hold additional crypto assets that are constituents of the Nasdaq Crypto US Settlement Price™ Index (“NCIUSS” or the “Index”), rather than being limited to bitcoin and ether. Accordingly, the Trust will track Bitcoin (“BTC”), Ethereum (“ETH”), Solana (“SOL”), Stellar Lumens (“XLM”) and XRP (“XRP”), as of this date, subject to quarterly rebalancing and any additional Index Constituents added from time to time in accordance with the Index methodology and eligibility under the generic listing standards.

In connection with this change, the Trust is also filing a prospectus supplement to update and supplement certain information contained in the Registration Statement on Form S-1 (No. 333-280990).

The Sponsor will continue to monitor the Index composition and will adjust the Trust’s holdings in order to replicate the Index, subject to the restrictions set forth on the generic listing standards.
