AI Saves XRP: Decade-Old Bug Nearly Unleashed Trillions in Counterfeit Crypto

A serious flaw hidden for over a decade in the XRP Ledger payment system could have allowed hackers to print an astounding 18.45 trillion XRP, an amount 184 times the cryptocurrency's entire current supply, threatening its $94 billion market value. This 'inflation bug' was recently discovered by security researcher Cayden Liao and his AI system, Veria AI, highlighting how advanced tools are now critical in finding deep-seated vulnerabilities in digital asset. Luckily, the bug was caught before any real-world exploitation, with Ripple's development team acting fast. The vulnerability, known as an 'integer overflow' error, meant that the system could miscalculate transaction totals, effectively creating new, unauthorized XRP out of thin air if a complex series of hundreds of trading offers were made in a single payment. This incident joins a growing list of crypto 'money-printing' bugs unearthed by AI since July 2026, including issues in Zcash and Liquid Network, underscoring a wider industry challenge. RippleX, Ripple's engineering division, quickly reproduced the bug, rated it critical, and deployed an emergency fix, 'xrpld 3.4.1', on September 25, 2026, bypassing the usual two-week validator voting process to ensure rapid protection. While RippleX confirmed no actual unauthorized XRP was created or lost on public networks, the close call has intensified scrutiny on blockchain security. The company is now boosting its AI-assisted testing and mathematical checks to find other hidden weaknesses. For investors, the immediate concern has eased, but the event caused XRP price to drop by 7.7% in five days. This episode is a stark reminder that even well-established digital asset face complex, long-standing threats that demand constant vigilance and innovative security solutions.
