Australia and XRP Ledger Made History With the Country's First Licensed Digital Dollar

Australia has granted a financial services license for AUDD, a regulated Australian dollar stablecoin, allowing banks and financial institutions to legally issue, hold, and transact in digital Australian dollars on the XRP Ledger (XRPL) and several other blockchain networks.

What Is the AUDD Stablecoin and Who Issued It?

AUDD is an Australian dollar-backed stablecoin issued by AUDC Pty Ltd. The Australian Securities and Investments Commission (ASIC), the country's primary financial regulator, granted AUDC an Australian Financial Services Licence (AFSL), authorizing it to provide non-cash payment facilities using the digital token.

A stablecoin is a digital token designed to hold a fixed value by being backed one-for-one with a traditional currency held in reserve. In AUDD's case, each token is backed by Australian dollars. The AFSL classification means AUDD is treated as a regulated financial product under Australian law, not an unregistered digital asset.

Importantly, AUDD is not a central bank digital currency (CBDC). The Reserve Bank of Australia (RBA) has its own separate eAUD research project, which remains experimental. AUDD is a privately issued, regulated stablecoin designed for corporate and institutional use.

Why Does the AFSL License Matter for Banks?

The AFSL removes legal uncertainty that previously made it difficult for Australian banks and businesses to interact with digital dollar instruments on blockchain networks. Without a license, holding or transacting in a stablecoin carries compliance risk for regulated institutions, particularly around anti-money laundering (AML) and know-your-customer (KYC) obligations.

With the AFSL in place, banks can now legally hold, trade, and settle in AUDD without stepping outside Australian financial law. This matters because regulated institutions cannot simply adopt new payment tools without a clear legal framework behind them.

Which Blockchains Does AUDD Support?

According to ASX filings, AUDD operates across multiple blockchain networks, giving institutions flexibility when it comes to liquidity management and settlement:

• XRP Ledger (XRPL)
• Ethereum
• Stellar
• Solana
• Hedera

Multi-chain support means that institutions are not locked into a single network and can use whichever chain best fits their operational needs.

Why Is the XRP Ledger Being Used for This?

The XRP Ledger is a public blockchain originally developed by Ripple that is designed for fast, low-cost payments and settlements. Transactions on XRPL typically settle in three to five seconds, and fees are a fraction of a cent, making it practical for high-volume payment flows that slower or more expensive blockchains cannot handle as efficiently.

XRPL has also recently launched a permissioned decentralized exchange (DEX), which allows regulated institutions to conduct on-chain trading while meeting KYC and AML requirements. A permissioned DEX differs from a standard decentralized exchange in that it restricts participation to verified users, making it compatible with institutional compliance frameworks.

What This Means for Australian Fintech

The AFSL license positions AUDD as an institutional-grade payment tool rather than a retail crypto product. For Australian fintech companies and banks exploring blockchain-based payment infrastructure, it provides a compliant entry point without the legal ambiguity that has slowed similar initiatives elsewhere.

That said, the license does not mean Australia's banking sector has fully adopted XRPL as a settlement network. Whether individual banks integrate AUDD into their systems depends entirely on their own implementation decisions.

A Recent Security Flaw on the XRP Ledger Adds Context

The AUDD announcement comes shortly after a serious security vulnerability was discovered in a proposed update to the XRP Ledger. A critical flaw in the Batch amendment for Rippled version 3.1.0, the core software that runs XRPL nodes, was caught by security engineer Pranamya Keshkamat from blockchain security firm Cantina on February 19, before the amendment went live on mainnet.

The bug lived inside the signature-validation process for batch transactions. A logic error in the validation loop created an early-exit condition that could have allowed attackers to execute unauthorized transactions from victim accounts without needing their private keys. 

If exploited, it could have enabled attackers to drain accounts to their reserve balance, alter ledger states, and potentially delete accounts entirely. Cantina CEO Hari Mulackal described it as a potential contender for the largest security hack by dollar value in blockchain history, given XRP's market cap of around $80 billion at the time.

The flaw was caught through a combination of static code analysis and Cantina's AI-powered auditing tool called Apex. From discovery to public disclosure took one week:

• February 19: Cantina reported the flaw; UNL validators were advised to vote against the Batch amendment
• February 23: Ripple released an emergency patch with Rippled version 3.1.1, marking the Batch amendment as unsupported
• February 26: XRPL Labs published the full public vulnerability disclosure

No funds were compromised. The incident demonstrates both the risks of deploying new blockchain amendments at scale and the value of independent security auditing before activation.

Conclusion

Australia's AFSL license gives AUDC a clear legal foundation to operate AUDD as a regulated digital dollar across multiple blockchains, including the XRP Ledger. Banks now have a compliant way to settle in digital Australian dollars without stepping outside financial law. The multi-chain design and XRPL's permissioned DEX add practical flexibility for institutional users. Full adoption across the banking sector is not guaranteed and will depend on individual implementation decisions. The recent XRP Ledger security flaw, caught and patched before any funds were at risk, is a useful reminder that regulated infrastructure still requires constant independent scrutiny.
