Chainlink has introduced a framework that lets financial institutions connect to Swift’s blockchain ledger without handing over their transaction-signing keys. The Chainlink Swift integration uses the Chainlink Runtime Environment (CRE) to coordinate workflows between bank systems and Swift’s shared infrastructure.
Launched on September 28, the new system works on the principle of self-signature. The banks retain the key that is required for signing transactions, but CRE will deal with the processes required to both read and write into the ledger of Swift.
The Chainlink Swift integration maintains the established process of transaction authorization. Institutions can gain access to tokenized payments through the Chainlink Swift integration without transferring their transaction authority to any other platform.
What Does the Chainlink Swift Integration Do?
CRE serves as the workflow layer that connects the internal architecture of a financial institution to the ledger system in Swift. It manages data and smart contract operations, although each bank still uses their signature system for transactions.

The same applies in managing activity within the tokenized deposit ledgers of banks and the blockchain system architecture of Swift. The deposits stay in the ledger of the bank where they originate from, while Swift manages payment commitments in a blockchain infrastructure.
Settlement is still done outside the ledger of blockchain. The banks can use the RTGS system, correspondent banking, and any other method agreed upon by the participating institutions.
Who Controls Transactions Under the New Framework?
Financial institutions maintain control of authorization all the way. The Chainlink Swift integration does not mean that banks will have to transfer their private keys or change any internal governance procedures.
Swift continues to be responsible for running its own ledger. Chainlink provides the connecting layer via CRE but not the signing credentials.
Sergey Nazarov, CEO of Chainlink Labs, stated that the company was backing up Swift as the banks were considering using tokenized deposits and ledgers. No timeline or bank was disclosed by either party about piloting the technology.
Why Is Swift Using Tokenized Bank Deposits?
Swift’s ledger will facilitate the process of cross-border payments at any time around the clock through the use of tokens from commercial bank deposits.
The Chainlink Swift integration means that tokens issued by banks will be able to operate together with the coordination layer of Swift but still remain connected to bank-controlled systems. In this model, the represented funds will stay on the balance sheets of commercial banks as payment instructions flow across the ledger.
It should be noted that Swift says the ledger is not a replacement for the current Swift messaging network. This ledger is intended to coordinate payment operations before the execution of the process through the bank’s infrastructure.
The first version of the ledger uses an Ethereum Virtual Machine-compatible architecture. It is built on Hyperledger Besu.
Which Banks Are Preparing Initial Swift Ledger Pilots?
In July, Swift had stated that there would be 17 banks in six continents who are ready for initial live transactions with tokenized deposits. The list comprises ANZ, BNP Paribas, BNY, Citi, DBS, HSBC, Standard Chartered, UBS, UOB, and Wells Fargo.
The tests are expected to run pilot tests in the form of making payments at night and weekends followed by settlements via existing processes. Over 40 institutions helped in designing the ledger.
HSBC has revealed that they will use their tokenized deposit services on the shared platform. Similarly, Standard Chartered, UBS, and UOB have termed their participation in the process as a way of tokenized payments, interoperability, and continuous money flow.
For all these institutions, the integration with Chainlink Swift is another path to ledger via existing tech stacks. It does not necessarily mean that all financial institutions on the Swift platform are shifting towards the blockchain platform.
When Will Swift Expand Its Blockchain Ledger?
In 2026, Swift began implementing the initiative beyond its prototype phase. By July, the first cohort of banks were working on real-world tokenized-deposit transactions within the context of a staged release.
Potential use cases include corporate treasury payments, programmable payment flows, foreign exchange transactions, and cash transactions related to securities transactions. Swift has noted that functionality and availability will increase beyond the initial rollout phase.
The Chainlink Swift integration builds upon prior collaboration between Chainlink and Swift around the topic of blockchain interoperability for institutions. Prior initiatives focused on testing the connection of Swift’s infrastructure to blockchain networks and tokenized assets.
For those banks that participate, the solution provides access without altering where control over transactional approval resides. The Chainlink Swift integration retains control with the institution but uses CRE to orchestrate the process between institutions and Swift’s ledger.
