IBM connects Digital Asset Haven to Swift ledger for tokenized deposits

IBM said Digital Asset Haven clients can now connect to Swift's blockchain-based shared ledger for tokenized deposit transactions. A new beta ISO 20022 messaging adapter lets institutions instruct transactions through the ledger using standard payment messages. Financial institutions participating in Swift's program have tested tokenized deposits on the ledger. The ledger supports bank-issued tokenized deposits. The ledger allows participating IBM clients to move digital assets 24/7. Final settlement takes place through existing systems. The adapter lets banks use existing payment message formats and operational processes instead of blockchain-specific workflows. Swift announced the ledger at Sibos 2025. More than 40 financial institutions worked with Swift on its design. Seventeen institutions are participating in a tokenized deposit pilot. Swift connects more than 12,500 financial institutions across over 200 markets. IBM is offering an on-premises beta deployment of Digital Asset Haven. Clients can install it on IBM Z and IBM LinuxONE in their own data centers. The deployment manages assets such as stablecoins and tokenized deposits without relying on public cloud infrastructure. The platform and its key management layer remain inside the client's environment. IBM Crypto Express hardware security modules protect the keys. Digital Asset Haven launched in October 2025 with software-as-a-service and hybrid deployment options. IBM built the platform with wallet infrastructure provider Dfns for banks, governments, and other regulated organizations. The on-premises version uses the same architecture, application programming interfaces, and workflows as Haven's software-as-a-service and hybrid options.
