Swift said on March 30 that it has completed the design phase of its blockchain-based shared ledger and is now building the first MVP iteration. The system is intended to support interoperability between banks' tokenized deposits for round-the-clock cross-border payments, according to the company's announcement. Participating banks in the MVP will begin live transactions in 2026. The initial use case is real time international payments, not securities issuance or fund distribution.
How it works
Swift said it will run the ledger while banks keep control of their own environments, keys, assets, funding, and settlement, using RTGS systems, correspondent banking, or other agreed mechanisms. The system is being built on an EVM-compatible architecture based on Hyperledger Besu, according to Swift's product page. It is designed to provide a shared, real time record of interbank commitments while fitting into existing compliance processes.
From experiments to an MVP
Swift has been running digital asset trials for some time now, and the March 30 update moves that work closer to production. In September 2025, Swift said it would add a blockchain-based shared ledger to its infrastructure with more than 30 financial institutions. In January 2026, the company said it had completed a separate interoperability trial involving tokenized bonds. The new announcement is narrower than a market-wide rollout: Swift's public materials describe staged development, and the March 30 update does not identify a final participant list, a precise go-live date, or any jurisdiction-specific approvals for the first live transactions.
Oversight and scope
Swift states that it is overseen by the G-10 central banks and the European Central Bank, with the National Bank of Belgium as lead overseer. No new rulemaking is involved. The ledger can support tokenized deposit payments as well as related cash movements for securities transactions, but the public documentation does not create new access rights for issuers or investors and does not announce a broader production launch beyond the MVP.
Who this affects
The immediate effect is on participating banks and financial institutions, and on digital asset platforms that may interface with those banks. For everyone else, this is a step forward in Swift's infrastructure roadmap, not a product launch.
