Hong Kong’s monetary authority has partnered with blockchain oracle provider Chainlink to facilitate cross-border settlements using its Cross-Chain Interoperability Protocol (CCIP) in the second phase of its e-HKD+ Central Bank Digital Currency (CBDC) pilot. This initiative enables secure exchanges between Hong Kong’s digital currency and an Australian dollar-denominated stablecoin issued by ANZ Bank, marking a significant advancement in blockchain-based financial infrastructure.
The collaboration involves major financial institutions including Visa, Fidelity International, and China Asset Management Company. Chainlink’s CCIP protocol serves as the technical backbone for atomic settlement of transactions across different blockchain networks, eliminating counterparty risk in cross-border exchanges.
This development follows Hong Kong Monetary Authority’s (HKMA) Fintech 2025 strategy that prioritizes CBDC research. Phase 1 of the e-HKD+ pilot focused on domestic retail payments, while Phase 2 expands to complex cross-jurisdictional use cases.

Chainlink’s Technical Implementation
Chainlink’s role centers on enabling secure messaging and transaction finality between the Hong Kong CBDC system and Australia’s stablecoin network. The CCIP protocol creates cryptographic proofs for asset movements across chains while maintaining regulatory compliance through built-in identity verification layers.
Key technical features include:
– Atomic swap functionality for simultaneous asset exchange
– Real-time forex rate oracles
– Regulatory reporting modules for both jurisdictions
e-HKD+ Pilot Program Structure
The HKMA-designed pilot tests three core capabilities:
1. Cross-border merchant payments
2. Foreign exchange hedging
3. Securities settlement
Participants can convert e-HKD to ASDC (Australian Stablecoin) through licensed exchanges at near-instant settlement speeds. The table below shows transaction benchmarks:
| Metric | Traditional System | Blockchain Solution |
|---|---|---|
| Settlement Time | 2-5 Days | Under 2 Minutes |
| Transaction Cost | $25-50 | $0.15-0.30 |
ANZ Bank’s Stablecoin Integration
Australia and New Zealand Banking Group (ANZ) issues the ASDC stablecoin collateralized 1:1 with AUD reserves. This marks the bank’s first blockchain-based currency instrument since its 2024 stablecoin framework approval. ANZ’s participation extends Australia’s Project Dunbar CBDC research into practical implementations.
The bank’s blockchain lead stated: “Our partnership with Chainlink and HKMA demonstrates how legacy financial institutions can leverage Web3 infrastructure without compromising regulatory standards” through the HKMA’s sandbox environment.
Market analysts note increased institutional interest in Chainlink’s oracle networks following this announcement. LINK token trading volume surged 40% on major exchanges within 24 hours of the news, though specific price movements remain excluded per editorial guidelines.
Industry experts predict this pilot could accelerate CBDC adoption across Asia-Pacific markets. The Bank for International Settlements (BIS) has endorsed the project as a model for multi-jurisdictional digital currency interoperability.
Future phases will explore:
– Integration with China’s digital yuan
– Tokenized securities settlements
– AI-powered liquidity management
