Chainlink has wormed its way into the plumbing of central bank digital currency projects and tokenized asset settlements across five countries. Brazil, Hong Kong, Australia, the United Kingdom, and participants in the multi-nation mBridge initiative are all running pilots that rely on Chainlink’s infrastructure to move government data and settle cross-border transactions.
The central bank roster
The highest-profile integration sits in Brazil, where the central bank’s Drex CBDC project has tapped Chainlink through a collaboration with Banco Inter. That partnership produced a cross-border trade settlement pilot connecting Brazil and Hong Kong, automating payments for tokenized assets in what amounted to a real-time proof of concept for programmable international commerce.
On the Hong Kong side, the Hong Kong Monetary Authority’s e-HKD project incorporated Chainlink’s Cross-Chain Interoperability Protocol, known as CCIP. The protocol handled cross-chain Payment-vs-Payment settlement between ANZ’s A$DC stablecoin and the e-HKD CBDC, essentially proving that a stablecoin issued by an Australian bank and a digital currency issued by Hong Kong’s monetary authority could swap value atomically across different ledgers.
