Chaince Digital Holdings Inc.

(a)Evaluation of Disclosure Controls and Procedures. We maintain disclosure controls and procedures designed to provide reasonable assurance that the information required to be disclosed by us in the reports that we file and furnish under the Exchange Act is recorded, processed, summarized and reported, within the time period specified in the SEC’s rules and forms, and that the information required to be disclosed by us in the reports that we file or submit under the Exchange Act is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, to allow timely decisions regarding required disclosure.

Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, has performed an evaluation of the effectiveness of our disclosure controls and procedures (as defined in Rule 13a-15(e)) under the Exchange Act) as of the end of the period covered by this report, as required by Rule 13a-15(b) under the Exchange Act. Based upon that evaluation, our management has concluded that, as of March 31, 2026, our disclosure controls and procedures were not effective, due to the material weaknesses identified by us, which are described under “Management’s Annual Report on Internal Control over Financial Reporting” of our Annual Report on Form 10-K.

(b)Changes in Internal Control Over Financial Reporting. There has been no change in our internal controls over financial reporting during the quarter ended March 31, 2026 that has materially affected, or is reasonably likely to materially affect, our internal controls over financial reporting.
