IBM Links Digital Asset Haven to Swift Blockchain Ledger

IBM announced Thursday that clients of its Digital Asset Haven platform can now connect to permissioned blockchain networks, including Swift's blockchain-based shared ledger, as reported by The Block. The new beta ISO 20022 messaging adapter allows financial institutions to instruct tokenized deposit transactions through the ledger using standard payment messages.

The ledger supports bank-issued tokenized deposits and enables participating clients to move digital assets 24/7, with final settlement taking place through existing systems. According to a release shared with The Block, the adapter allows banks to build on existing payment message formats and operational processes rather than adopting blockchain-specific workflows. IBM noted that financial institutions participating in Swift's program have already tested tokenized deposits on the ledger using Digital Asset Haven.

Swift first announced the ledger at Sibos 2025, based on a prototype developed with Consensys. The platform’s design involved collaboration with more than 40 financial institutions, while 17 are currently participating in a tokenized deposit pilot. Globally, Swift connects over 12,500 financial institutions across 200 markets. The new option is deployable on IBM Z and IBM LinuxONE inside a client’s own data center, handling stablecoins and tokenized deposits on private infrastructure. IBM stated that the platform and its key management layer stay within the client's environment, protected by IBM Crypto Express hardware security modules. Digital Asset Haven began operations in October 2025, offering SaaS and hybrid deployment options built with wallet infrastructure provider Dfns.

"The financial services industry is entering a new era where tokenized and traditional assets will need to move side by side," Tom McPherson, general manager, IBM Z and LinuxONE, said. "By connecting to Swift's shared ledger and extending IBM Digital Asset Haven to on-premises environments, IBM is helping clients participate in emerging digital asset networks while prioritizing control of their most critical financial operations."
