Chainlink Adds a Self-Signing Route into Swift’s Blockchain Ledger
Chainlink says CRE will connect banks and their key infrastructure to Swift’s ledger for tokenized-deposit workflows while institutions retain transaction authorization.

Chainlink announced on September 28 that it is enabling financial institutions to connect their systems and signing infrastructure to Swift’s blockchain ledger. Chainlink Runtime Environment will orchestrate the workflow, while each institution keeps control of the keys that authorize transactions. The stated use case is round-the-clock movement of tokenized commercial-bank deposits.
The arrangement joins two ledgers rather than replacing bank money with a public token. Deposits remain on participating banks’ own ledgers and balance sheets; Swift’s ledger coordinates transfers between institutions, including outside normal banking hours. The self-signing design preserves existing approval and security processes, but the announcement describes enabling infrastructure. It should not be read as evidence that every Swift member has deployed the workflow or that large payment volumes have already moved through it.
