1 October 27, 2025 Attention: Business Editors VERSABANK UNVEILS BRANDING FOR PROPREITARY DIGITAL DEPOSIT RECEIPTS: VERSABANK REAL BANK DEPOSIT TOKENS™ REFLECTS CRITICAL ADVANTAGE OF ISSUANCE BY A FEDERALLY LICENSED BANK LONDON, ON/CNW – VersaBank (TSX: VBNK; NASDAQ: VBNK), a North American leader in business-to-business digital banking, as well as technology solutions for cybersecurity, today unveiled branding for its proprietary Digital Deposit Receipts (DDRs): VersaBank Real Bank Deposit Tokens™ (RBDTs™). The brand reflects the critical advantage of the Bank’s RBDTs™ compared to stablecoins of being issued by a federally licensed bank (in both the United States and Canada), enabling legally permitted interest payments and deposit insurance1, which non-bank issued stablecoins are not allowed to provide. The brand also reinforces the critical functional foundation that RBDTs™ are actual cash deposits with the Bank that are reflected on the blockchain. “The branding of VersaBank Real Bank Deposit Tokens™ is an important step as we prepare for the anticipated commercialization of our proprietary in the coming months2,” said David Taylor, Founder and President, VersaBank. “VersaBank Real Bank Deposit Tokens™ combine the safety and soundness of traditional banking with the efficiency, cost savings, security, and programmability of blockchain technology. As the only dual-chartered national bank currently integrating and running cross-border pilot programs, we are proud to continue our track record of innovation and to demonstrate the many benefits of our RBDTs™ across both the US and Canada.” About VersaBank’s Real Bank Deposit Tokens VersaBank Real Bank Deposit Tokens™ (RBDTs™) (previously known as Digital Deposit Receipts, or “DDRs”) are VersaBank's proprietary tokenized deposits, functioning as digital representations of traditional bank deposits on a blockchain, offering enhanced efficiency, programmability, and security in financial transactions.
