Chainlink Builds Access Layer for Swift Ledger

Chainlink is developing a connection layer that would let financial institutions access Swift’s blockchain ledger while retaining control of the keys used to authorize transactions.

The planned integration will use the Chainlink Runtime Environment, or CRE, to coordinate workflows between banks’ internal systems and Swift’s ledger. It is designed for institutions moving tokenized deposits across borders without handing transaction signing to an external operator.

CRE Lets Banks Retain Control Of Transaction-Signing Keys

CRE uses a self-signing model in which each institution keeps control of its own transaction keys. Chainlink would coordinate the workflow linking bank systems to Swift while existing security controls, approval processes and governance remain with the bank.

The setup is designed to let institutions use smart contracts across their own deposit ledgers and Swift’s shared infrastructure without replacing the signing systems already used for regulated payment operations.

Swift Ledger Coordinates Tokenized Deposit Payments Before Final Settlement

Swift’s ledger coordinates tokenized-deposit payments between participating banks before final settlement occurs through existing payment systems.

Tokenized commercial bank deposits remain on each institution’s own ledger and balance sheet, while Swift’s shared ledger coordinates the payment workflow. Final settlement can continue through existing arrangements, including real-time gross settlement systems.

That structure is intended to extend payment availability across nights and weekends without requiring banks to rebuild their underlying settlement infrastructure.

Banks Have Begun Live Transactions On Swift’s Blockchain Infrastructure

Swift said in July that its ledger was ready for initial use after nine months of development involving more than 40 financial institutions and initially named 17 banks across six continents for live tokenized-deposit activity.

Several institutions have since completed live transactions on the ledger, moving the project beyond its initial testing phase.

Chainlink’s planned integration would give banks another route into that infrastructure without requiring them to build a direct connection from scratch. Swift connects more than 11,500 financial institutions and corporates across more than 200 markets.

The next step is whether financial institutions begin adopting Chainlink’s CRE-based connection as Swift expands live use of its ledger for tokenized deposit payments.
