IBM has connected Digital Asset Haven to Swift's blockchain-based shared ledger through a beta ISO 20022 messaging adapter, allowing banks and other regulated institutions to instruct tokenized-deposit transfers using existing payment formats and compliance processes. Swift developed the ledger with more than 40 financial institutions and launched it in July; 17 banks joined the initial pilot, including HSBC, Citi, BNP Paribas, UBS and Standard Chartered. HSBC and Standard Chartered completed the first live cross-border transaction on the ledger in August. IBM has also introduced a beta on-premises deployment running entirely on IBM Z and LinuxONE hardware, enabling clients to keep the platform and key-management layer inside their own data centers, with IBM Crypto Express hardware security modules protecting keys. Digital Asset Haven launched in October 2025 through IBM's collaboration with wallet infrastructure provider Dfns. Separately, Circle said on July 27 that it acquired nearly 1,000 blockchain patents from IBM.
