Enterprise technology giants Oracle and Chainlink have unveiled separate integration frameworks that will allow financial institutions to connect their existing banking infrastructure to Swift’s new blockchain ledger, marking a significant step toward tokenized-deposit payments across the global financial system.
Oracle said its integration will use Oracle Blockchain Platform and Oracle Digital Assets Data Nexus as a pre-integrated technical foundation for the connection. The stack will host Swift commitment contracts, support event orchestration, and provide EVM-compatible blockchain infrastructure, wallet custody, transaction signing, integrations and smart contract functionality for tokenized deposit operations. Oracle Banking Payments will then connect those blockchain-based payment flows with existing ISO 20022 processing at institutions. The company said the approach allows financial institutions to operate their own tokenized deposit infrastructures while maintaining traditional payments and digital asset operations under a unified operating model.
Chainlink, meanwhile, announced a connection framework built around the Chainlink Runtime Environment (CRE). The CRE will sit between a bank’s infrastructure and the Swift ledger, coordinating workflows while institutions retain their transaction-signing keys. Under this self-signing model, banks can keep existing approval procedures, security controls and operating models while adopting tokenized payment services. Chainlink Labs CEO Sergey Nazarov said the company was “thrilled to be supporting the Swift ledger” as banks seek technology for tokenized deposits and ledger connectivity.
Swift’s ledger is designed to coordinate 24/7 cross-border payments using tokenized commercial-bank deposits that remain on each issuing bank’s balance sheet and ledger. Payment orchestration occurs before settlement, while final settlement continues through real-time gross settlement systems, correspondent banking arrangements or other mechanisms agreed between participants. Swift has stressed the blockchain ledger does not replace its role as a global financial messaging network.
The project has moved quickly since its announcement at Sibos in September 2025. By March 2026 Swift completed the design stage and moved into MVP implementation with more than 40 institutions contributing. In July, Swift said 17 banks across six continents were preparing initial live pilots, including 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. Swift’s existing network already connects more than 11,500 institutions and corporates across more than 200 markets, moving an amount equivalent to world GDP roughly every two to three days.
