The XRP Ledger Foundation has addressed questions surrounding a recently patched critical vulnerability, confirming that no additional XRP was created through the flaw. In a statement published on October 12, 2026, the foundation explained how the bug could have bypassed the network’s supply safeguards, why developers deployed an emergency fix and how validators coordinated the response.
The vulnerability involved an integer overflow in payment processing that could have allowed deliberately constructed transactions to credit sellers with more XRP than buyers paid. Although the potential consequences raised concerns about the ledger’s fixed supply, the foundation said its monitoring and independent community checks found no evidence of newly created XRP.
The issue was addressed in xrpld version 3.4.1, released on September 25. The foundation said the fix closed a route around the XRP Ledger’s supply protections, while emphasizing that all account balances and transactions remain publicly verifiable on the network.
XRP Supply Remains Publicly Verifiable After Security Fix
The XRP Ledger launched with a fixed supply of 100 billion XRP, and its protocol does not provide a normal mechanism for creating additional tokens. According to the foundation, the vulnerability could have circumvented that rule under specific transaction conditions, but it was not used to increase the supply on the public network.
The foundation estimates that approximately 99.986 billion XRP currently exist. The difference from the original supply reflects transaction fees that have been permanently destroyed over the ledger’s history. This makes XRP’s supply gradually deflationary, although the amount removed through fees is small relative to the total supply.
The foundation also stressed that XRP balances cannot be hidden in an undisclosed account on the public ledger. Anyone can examine transaction records and account balances using blockchain explorers and other data services, providing a way for researchers to independently check supply claims rather than relying solely on statements from developers.
The vulnerability reportedly required hundreds of deliberately constructed operations and was not triggered by ordinary payments. That complexity helps explain why the flaw remained undetected for years, but it also highlights the difficulty of identifying rare interactions between arithmetic operations and transaction-processing rules.
The foundation credited Cayden Liao and Veria AI with discovering and responsibly reporting the issue. It said the incident reinforced the need for closer collaboration between independent security researchers, RippleX, core developers and the wider XRP Ledger community.
Emergency Patch Highlights Decentralized Governance and AI Security
The foundation said developers faced a difficult decision about how to distribute the fix. Under the conventional amendment process, technical details about the vulnerability could have become public weeks before the change took effect, potentially giving attackers time to develop an exploit. The team therefore coordinated a direct software release intended to reduce that exposure.
According to the statement, the foundation, RippleX, core developers and validators reached a shared agreement on the response. The patched software was provided to validators on the default Unique Node List using contact information published in their xrp-ledger.toml files, and public binaries followed on September 25.
The foundation emphasized that no single organization could impose the software change on the entire network. Validators and node operators independently choose which software to run, while protocol changes continue to use the amendment process. The foundation said version 3.4.1 became required through a normal amendment vote after receiving more than 80% validator support over two weeks.
Looking ahead, the foundation plans to expand formal verification, introduce AI-assisted adversarial testing and strengthen its bug bounty program. Formal verification can help prove that software satisfies specified properties, while adversarial testing can search for unexpected transaction combinations and edge cases. Neither approach guarantees that every vulnerability will be found.
The statement also acknowledged that artificial intelligence can accelerate vulnerability discovery for both attackers and defenders. The foundation’s challenge will be to use those capabilities to identify flaws earlier, coordinate fixes safely and maintain transparent verification without unnecessarily exposing the network to exploitation.
For XRP holders, the central takeaway is that the foundation reported no supply inflation from the vulnerability, and the ledger’s public data allows that claim to be independently examined. The episode nevertheless demonstrates that a fixed token supply depends on correct software implementation, continuous security research and effective coordination among independent network participants.
