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.

Australia’s involvement comes through ANZ, the Australia and New Zealand Banking Group, which has been one of the more aggressive traditional banks in experimenting with stablecoins and tokenized assets. ANZ’s demonstrations using Chainlink focused on settling tokenized assets across public blockchains.

The Bank of England entered the picture in February 2026, selecting Chainlink for its Synchronisation Lab. The lab’s mission is testing atomic settlement with onchain securities.

Rounding out the five-country footprint is Chainlink’s role in addressing interoperability challenges highlighted by mBridge, the multi-CBDC platform involving monetary authorities from China, Hong Kong, Thailand, and the UAE. Chainlink’s CCIP addresses the core technical problem: making different digital currencies talk to each other without a centralized intermediary acting as translator.

Why CCIP is the product that matters

Chainlink’s CCIP enables actual value transfer and message passing between entirely separate blockchain networks. Chainlink’s infrastructure handles secure data feeds, cross-chain connectivity, compliance checks, and automated transaction mechanisms like Delivery-vs-Payment and Payment-vs-Payment settlements.

What this means for investors

For LINK, Chainlink’s native token, the expanding use cases across both public DeFi and centralized finance create a dual demand profile. The Brazil-Hong Kong trade finance experiment completing successfully in late 2025 suggests at least some of these projects are moving beyond the science-fair stage.

The risk is that pilots remain pilots. Central bank technology projects have a long and storied history of impressive demonstrations that never reach production scale. The gap between a successful cross-border settlement test and a live system processing billions in daily volume is measured in years and political will, not just technical capability.
