Westpac and the Reserve Bank of Australia Initiate Tokenized Asset Settlement Initiative Utilizing Chainlink Technology

Westpac Institutional Bank has collaborated with Chainlink and Imperium Markets to establish blockchain-based tokenized asset settlement functionalities through Project Acacia.

The Chainlink Runtime Environment will facilitate secure Delivery vs. Payment (DvP) settlement of tokenized assets across blockchain markets and Australia’s existing PayTo domestic payments framework.

Australia’s central bank has projected that tokenization could lead to savings of up to AUD $12 billion annually for asset issuers in Australian markets.

This initiative builds upon the RBA’s broader six-month pilot program announced in July, which selected 24 industry participants to execute 19 real-money transactions and five proof-of-concept simulations across various asset classes.

Westpac Enhances PayTo Infrastructure for Tokenized Asset Transactions

Westpac’s proof of concept aims to illustrate that the current PayTo infrastructure can manage the settlement and clearing of substantial wholesale banking payments necessary for tokenized asset transactions.

PayTo, introduced by Westpac in 2024, functions as a digital-first alternative to direct debit payments, enabling real-time transactions with improved visibility and control for customers.

The system settles transactions utilizing banks’ existing exchange settlement accounts with the RBA while providing comprehensive transaction data, verified authorization, and secure storage capabilities.

Jeff Byrne, Managing Director of Global Transaction Services at Westpac Institutional Bank, stated that the bank is “assisting the RBA in exploring what digital currencies could resemble in practical applications, while offering our customers access to new payment options in a safe and secure manner.”

In addition to the immediate settlement capabilities, the project expands Westpac’s PayTo functionalities to emerging technologies such as asset tokenization, while showcasing methods to unlock new value while safeguarding customers.

The proof of concept also allows Westpac to evaluate post-quantum cryptography in financial systems, employing advanced encryption algorithms designed to withstand potential future quantum computer threats.

David Walker, Westpac’s Chief Technology Officer, characterized the initiative as “a practical opportunity to learn and develop something that will be significantly important in the future, and something we may need to implement at scale.”

Westpac holds a long-term equity investment in Australian cybersecurity firm QuintessenceLabs, which has created quantum-enhanced cryptography solutions already utilized in defense and large organizational applications.

Walker remarked that “developing the next generation of payments architecture necessitates the strategic collaboration of all banks, telecommunications companies, retailers, and governments working in unison.”

The Australian Securities and Investments Commission has provided regulatory relief to enable testing, with project results anticipated in the first quarter of 2026.

Global Financial Institutions Accelerate Blockchain Infrastructure Development

Chainlink has positioned itself at the core of a potential $260 trillion market opportunity through collaborations with major financial institutions to unlock the untokenized assets market via its Cross-Chain Interoperability Protocol.

Earlier this year, Chainlink partnered with Abu Dhabi Global Market to establish blockchain standards and investigate tokenization frameworks within regulated environments.

RedStone’s market analysis also indicates that the tokenized real-world assets market reached $24.31 billion by June 2025, propelled by a 260% increase from $8.6 billion at the beginning of the year, with private credit accounting for over half of the total market value at $14 billion.

Significantly, Australia’s approach contrasts with the restrictive measures some of its major banks have adopted towards crypto platforms, with the National Australia Bank blocking payments to specific crypto exchanges in 2023, citing concerns regarding scams.

Project Acacia’s emphasis on regulated institutional applications could yield AU$19 billion annually in economic benefits, as noted by Professor Talis Putnins from the Digital Finance Cooperative Research Centre.

Organizers have described Australia’s real-money settlement testing on third-party platforms as a world-first for the nation in the digital finance sector.
