Dynamite Blockchain Provides Corporate and Disclosure Updates

As a result of a review by the British Columbia Securities Commission, we are issuing the following press release to retract and clarify our disclosure.

Vancouver, B.C., September 17, 2025 Dynamite Blockchain Corp. (the "Company" or "Dynamite") (CSE: KAS) wishes to provide clarification regarding certain disclosures made in prior Company filings and news releases relating to Kaspa Secure Technologies Inc. ("Kaspa Secure") and Kaspa Secure's IMME Wallet technology.

At the time of Dynamite's acquisition of Kaspa Secure in May 2025, the IMME Wallet application was fully developed and functionally operational from a technical standpoint. However, before launching the wallet commercially, the Company intends to complete the following:

dot integration of the Kaspa blockchain into the IMME Wallet;

dot rebranding of the product under the Company's go-to-market strategy; and

dot undertaking testing, compliance review, and user-experience refinements.

This work is estimated to require approximately 2 3 months of development and quality assurance and the anticipated costs are estimated at CAD $50,000 $60,000. These activities represent the "development milestones" referenced in the Company's news release dated July 24, 2025.

The Company retracts prior statements that the IMME Wallet or Kaspa Secure's solutions were "industry-leading," "market-leading," and provided a "best in-class crypto experience." As the wallet is not yet in commercial use, these claims are unproven. The Company confirms it will refrain from using such statements going forward.

The Company also confirms that Kaspa Secure is not currently providing "security, compliance, and digital identity solutions" and is not currently "providing businesses with seamless compliance tools." These capabilities represent intended future functionality, subject to further development and integration.

The IMME Wallet is considered proprietary, as it was internally developed by Kaspa Secure in 2022, with the source code and technical architecture owned by Kaspa Secure. No third-party licensing agreements govern its operation.

Although originally developed in 2022, management considers that the IMME Wallet remains current and commercially viable because, among other things: Dynamite Blockchain Corp.

dot the codebase is modular and designed for blockchain-agnostic integrations;

dot core security and relevant modules remain applicable; and

dot planned updates (Kaspa blockchain integration, UX refinements) are expected to align with 2025 commercial requirements.

The audited financial statements of Kaspa Secure, included in the Company's business acquisition report filed on www.sedarplus.com respecting Kaspa Secure, referenced "copyrights" and "trademarks." Upon further review, Kaspa Secure does not hold any registered copyrights. This disclosure was incorrect and is hereby retracted. Kaspa Secure holds one registered trademark, covering the "IMME" brand name in Canada, with an expiry date of September 2032. Kaspa Secure does not have any other registered trademarks.

The Company retracts prior disclosure that the IMME Wallet was the "world's first regulated and compliant digital identity and crypto wallet." The Company has not obtained a regulatory designation or licensing for the wallet. No regulator currently oversees the IMME Wallet.

On behalf of the Company,
