While global interest in central bank digital currencies (CBDC) is in slight decline, Hong Kong is actively pursuing its e-HKD project. The Hong Kong Monetary Authority (HKMA) has integrated Chainlink CCIP (Cross-Chain Interoperability Protocol) into the pilot phase of its CBDC to facilitate cross-border settlements between public and private blockchains.

Hong Kong chooses Chainlink to test e-HKD
Hong Kong Monetary Authority (HKMA) has integrated the inter-chain interoperability protocol (CCIP) of Chainlink in the second phase of its CBDC program, launched on September 23, 2024. The project involves 11 business groups exploring different use cases for e-HKD, Hong Kong’s future digital currency.
The experiment focuses on a specific use case involving Australian and Hong Kong financial players. It requires therefore test the ability to orchestrate the exchange of digital assets between several jurisdictions using various forms of electronic currencies and tokenized financial instruments. These technical tests assess settlement times, transaction security and the integrity of exchanged data.
To achieve this, Chainlink’s Cross-Chain Interoperability Protocol (CCIP) plays a central role. Designed to connect blockchains with different architectures, both authorized and unauthorized, CCIP facilitates communication between networks that are usually technologically isolated. As part of this experiment, it is being deployed on the Ethereum Sepolia test network, a secure environment serving as a laboratory before any real deployment.
The partners in this initiative include major players in the financial sector:Visa as a technology provider, Australia and New Zealand Banking Group (ANZ) for banking expertise, and asset managers ChinaAMC and Fidelity International.
CBDCs and the realities of the global marketplace
Paradoxically, the Hong Kong project is emerging against a backdrop of a global cooling of enthusiasm for digital currencies. A recent survey reveals a significant decline in initial enthusiasm, with the number of central banks actively engaged in these developments halving since 2022. This significant drop underscores the technical, regulatory and political challenges facing these projects.
Yet Hong Kong persists with its vision, joining a select club of territories determined to bring their CBDC projects to fruition. The European Union is stepping up its efforts to develop its platform, while Israel published a preliminary draft digital shekel last March.
In short, Hong Kong’s CBDC project adopts a unique strategy combining two types of blockchain technology. On the one hand, it uses closed, secure networks, monitored by financial authorities to ensure regulatory compliance. On the other, it operates networks that are open and accessible to all, encouraging innovation and participation by as many people as possible. The conclusions of this experiment, scheduled for the end of this year, could potentially guide other countries in designing their own digital currencies in the future.
As a journalist at Coinpri, I’ve been captivated by the world of bitcoin and blockchain since 2020. The decentralized aspect of Bitcoin particularly piqued my interest. Since then, I’ve been working constantly to spread my knowledge, hoping one day to see a world where everyone fully enjoys their financial freedom.
