Chainlink to Link Banks to Swift Ledger for 24/7 Payments

Chainlink is working to give financial institutions a way to connect their own systems and transaction-signing infrastructure directly to Swift’s blockchain ledger, according to Thenewscrypto. The company announced the effort on September 28, 2026, saying its Chainlink Runtime Environment (CRE) would coordinate workflows between banks and the shared ledger while banks keep the private keys used to authorize transactions.

The arrangement is aimed at 24/7 cross-border payments built on tokenized bank deposits, with 17 financial institutions preparing to pilot live transactions. Swift’s ledger had moved into initial use by July 2026, following a development effort that drew contributions from more than 40 financial firms.

Key facts

• Chainlink announced the Swift ledger connection on September 28, 2026, using its Chainlink Runtime Environment to coordinate workflows between institutions and the shared ledger.
• Banks retain control of the private keys used to sign transactions, rather than handing that authority to Chainlink.
• Swift’s ledger is designed for 24/7 cross-border payments using tokenized bank deposits, with 17 financial institutions across six continents preparing live pilots.
• Swift’s network connects more than 11,500 financial institutions and corporates across more than 200 markets, and the cooperative says its infrastructure moves an amount equivalent to world GDP roughly every two to three days.
• The ledger runs on an Ethereum Virtual Machine-compatible architecture based on Hyperledger Besu, which Swift operates as an orchestration layer.

Banks keep their own signing keys

The framework is built around a self-signing model. CRE sits between a financial institution’s systems and Swift’s ledger, handling the coordination needed to read from and write to it, but never taking control of authorization keys. Chainlink said the structure lets institutions preserve existing approval procedures, security controls and operating models while adopting tokenized payment services.

Banks also keep authority over their assets, funding and final settlement arrangements, and can use the connection to manage smart-contract activity across their own tokenized-deposit ledgers. Crypto.news reported that Chainlink CEO Sergey Nazarov said the company was pleased to be supporting the Swift ledger as banks look for technology to support tokenized deposits and ledger connectivity.

Where the deposits actually sit

Swift’s ledger does not replace the messaging network or move a public cryptocurrency asset. The tokens represent commercial-bank deposits that remain on each issuing bank’s own balance sheet and ledger, and Swift’s system records and validates payment commitments between institutions so transactions can progress outside normal banking hours. Final settlement still runs through existing mechanisms such as real-time gross settlement systems, correspondent banking arrangements or other routes agreed between participants.

Swift reported in July that the 17-bank pilot group includes ANZ, BNP Paribas, BNY, Citi, DBS, First Abu Dhabi Bank, FirstRand Bank, HSBC, Itaú Unibanco, Lloyds Bank, Mashreq, MUFG Bank, OCBC, Standard Chartered, UBS, UOB and Wells Fargo, a list Crypto.news carried. HSBC has said it plans to connect its Tokenised Deposit Service to the shared infrastructure, while Standard Chartered, UBS and UOB have described their participation as work on tokenized payments, interoperability and round-the-clock money movement.

Why it matters

Chainlink’s access layer gives banks a route into Swift’s blockchain infrastructure without transferring signing authority to a third party, which addresses a recurring objection from institutions weighing on-chain payments. The work extends a relationship between Chainlink and Swift that has covered institutional blockchain interoperability for several years. It also does not mean every institution on the Swift network is moving onto the ledger: the September 28 release describes a connection option, while Swift’s controlled rollout centers on its initial participating banks.

What to watch

Neither Chainlink nor Swift has given a date for a full rollout of the connection across participating banks, and Chainlink has not identified which pilot banks will use CRE first, according to Crypto.news. Swift has said the ledger’s functionality and availability will expand after the controlled go-live phase, with corporate and treasury payments identified as an early focus in earlier implementation documents.

Chainlink also launched CCIP 2.0 on September 28, aimed at institutional interoperability across public and private blockchains. The details above are not financial advice, and cryptocurrency and tokenization markets remain volatile and uncertain.
