Hgraph Develops Interoperability Solution in Collaboration with AP+ for Project Acacia
As digital payments and tokenised finance evolve, the question is no longer if, it’s how they integrate securely and seamlessly with today’s financial systems.
That’s what Project Acacia is designed to explore: a national initiative led by the Reserve Bank of Australia (RBA) and the Digital Finance Cooperative Research Centre (DFCRC), supported by ASIC, APRA, and the Australian Treasury. The program brings together financial institutions, technology partners, and infrastructure providers to test how regulated digital money, including stablecoins, bank deposit tokens, and a potential wholesale CBDC, can operate across networks, platforms, and use cases.
Under the Project Acacia initiative, Australian Payments Plus (AP+) is demonstrating how regulated Australian stablecoins can function safely across different systems and payment environments. AP+ has partnered with Hgraph to build the bridging and interoperability layer that makes this possible.
“I’ve had the utmost pleasure of working with the Hgraph team on this crucial, bridging component of the AP+ Project Acacia solution architecture. Not only do they deliver software development quickly, but they also understand the overall vision and bring a confident, steady hand to AP+ to ensure that the best possible experience for our stakeholders is realized.”
What Project Acacia Is Exploring
Project Acacia isn’t about creating new speculative crypto-assets. It’s about testing the infrastructure that can support the next generation of digital value; regulated, auditable, and interoperable by design.
By running coordinated experiments across multiple ledgers and participants, the initiative is helping shape how digital money could integrate into Australia’s trusted financial ecosystem.
Key highlights:
Initiated by the RBA and the DFCRC in late 2024 as a national research collaboration.
24 industry use cases are being tested across tokenised asset markets, settlement systems, and payment innovations.
The goal: build a practical, regulated foundation for digital-money interoperability in wholesale and enterprise finance.
Hgraph’s Role: Building the Bridge
For AP+’s participation in Project Acacia, the challenge is interoperability; enabling a regulated stablecoin to move between networks and systems without friction or loss of trust.
That’s where Hgraph comes in.
We’ve built a secure, scalable interoperability layer that allows digital value to flow safely between ledgers, wallets, and financial networks. Our design principles focus on:
Security and auditability, ensuring every transaction can be verified end-to-end.
Permission awareness, supporting regulated issuance and redemption flows.
Composability, allowing new systems and participants to be added easily.
Performance, ensuring reliable, real-time operation suitable for payment-grade environments.
This infrastructure connects the dots between systems, enabling real interoperability within regulated digital-money experiments like AP+’s stablecoin initiative.
“When looking for a trusted technology partner to assist the AP+ team in delivering the core bridging component underpinning the Project Acacia platform, we turned to Hgraph with their track record for fast, high-quality development and expertise in cross-chain infrastructure for tokenized assets.”
Why It Matters
Digital money has the potential to redefine how value moves, but only if it can work seamlessly across today’s diverse systems. Interoperability is what makes that possible.
By powering AP+’s interoperability layer, Hgraph is helping demonstrate how a regulated Australian stablecoin could coexist with, and enhance, existing payment rails. It’s a glimpse of how digital currencies can enable faster, transparent, and more efficient financial interactions across the economy.
For institutions, regulators, and innovators, this is a real-world step toward scalable, compliant digital finance.
Shaping What’s Next
Project Acacia is more than a research exercise, it’s a blueprint for Australia’s digital-finance future. Each participant is helping test different layers of that future system, from issuance and tokenisation to interoperability and settlement.
At Hgraph, we’re focused on the connective tissue that makes it all work, bridging networks, assets, and participants into one cohesive digital economy.
Together with AP+ and other industry leaders, we’re building the infrastructure that will enable value to move as easily as information.
