Item 1.01. Entry into a Material Definitive Agreement.

On March 13, 2026, Hashdex Asset Management Ltd., a Cayman Islands limited company (the “Sponsor”), and the Hashdex Nasdaq CME Crypto Index ETF, a Delaware statutory trust (the “Trust”), entered into the Second Amendment to the Sponsor Agreement (the “Second Amendment”). The Sponsor Agreement was originally dated January 27, 2025, and was previously amended by the Amendment to Sponsor Agreement, dated November 12, 2025. The Second Amendment reduces the Sponsor’s management fee (the “Sponsor Fee”) from 0.50% to 0.25% per annum of the Trust’s net asset value, effective as of March 16, 2026.

The foregoing description of the Second Amendment does not purport to be complete and is qualified in its entirety by reference to the full text of the Second Amendment, a copy of which is filed as Exhibit 10.1 to this Current Report on Form 8-K and incorporated herein by reference.

Item 7.01. Regulation FD Disclosure.

On March 16, 2026, the Trust issued a press release announcing the reduction of the Sponsor Fee. A copy of the press release is furnished as Exhibit 99.1 to this Current Report on Form 8-K.

The information in this Item 7.01, including Exhibit 99.1, shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended, or otherwise subject to the liabilities of that section, nor shall it be deemed incorporated by reference in any filing under the Securities Act of 1933, as amended, or the Securities Exchange Act of 1934, as amended, except as expressly set forth by specific reference in such a filing.

Item 8.01. Other Events.

As disclosed in Item 1.01 above, the Sponsor Fee has been reduced from 0.50% to 0.25% per annum. Prior to the Second Amendment, the Sponsor had been waiving a portion of the Sponsor Fee pursuant to the Amendment to Sponsor Agreement, dated November 12, 2025, resulting in an effective fee of 0.25% per annum through December 31, 2026. As a result of the fee reduction, the fee waiver provision is no longer in effect.

An updated prospectus supplement reflecting the reduced Sponsor Fee will be filed under Rule 424(b)(3) of the Securities Act of 1933.
