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 June 30, 2026, our disclosure controls and procedures were not effective, due to the material weaknesses identified by us, including (i) insufficient formal documentation of internal control policies and procedures relating to financial reporting processes; (ii) limited segregation of duties due to the relatively small size of the Company’s accounting and finance staff, which results in certain individuals performing multiple roles in accounting, financial reporting, and operational functions; and (iii) insufficient number of personnel with appropriate knowledge of U.S. GAAP and SEC reporting requirements, and lack of a fully developed internal accounting and financial reporting infrastructure. These material weaknessesare 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 control over financial reporting during the three months ended June 30, 2026 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.
