IBM announced on September 24 a beta connection between its Digital Asset Haven platform and SWIFT's shared ledger for tokenized deposits. The connection uses an ISO 20022 Messaging Adapter that allows participating banks to instruct ledger transactions through standard payment messages they already use.
The adapter maps ISO 20022 payment instructions to transactions on SWIFT's permissioned ledger, enabling institutions to test transfers of bank-issued tokenized deposits. Participating clients can move digital assets around the clock through the ledger, though final settlement continues to use existing mechanisms such as real-time gross settlement systems. This means tokenized-deposit transfers can move ahead of the final settlement step.
Digital Asset Haven provides wallets, key management, transaction signing, and policy controls for regulated organizations. The adapter works alongside Haven's digital-asset controls and Hyperledger Besu connectivity. According to IBM, institutions already participating in SWIFT's program have tested tokenized deposits on the shared ledger with Haven.
SWIFT announced in July that its ledger was ready for initial use, with 17 banks preparing to pilot live tokenized-deposit transactions. IBM's September announcement introduces Haven as a beta route into that pilot effort.
On-Premises Deployment Option
IBM also announced a separate on-premises beta for regulated institutions that want to run Haven entirely within their own data centers on IBM Z or LinuxONE infrastructure, without relying on public-cloud services. Both the solution layer and key-management layer remain within the client's environment.
IBM says the on-premises option uses the same architecture, APIs, and workflows as Haven's SaaS and hybrid deployments. This allows institutions to evaluate the deployment choice separately from the SWIFT connection, focusing on where keys and platform operate while testing whether the messaging adapter fits their payment processes.
