XRP Ledger Patches Decade-Old Bug That Could Have Minted Trillions of XRP

What happened: The XRP Ledger team patched a critical integer overflow bug in its payment engine that could have allowed an attacker to mint up to 18 trillion XRP—184 times the intended supply—via a single transaction. The flaw, present since 2015, was discovered by AI security startup Veria Labs and fixed on September 25, bypassing the usual validator-vote process due to its severity. No evidence of exploitation was found, and a $250,000 bounty was awarded for the AI-led discovery.

Why it matters: The incident underscores both the long-term risks of legacy code in major blockchains and the growing role of AI in vulnerability discovery. The decision to bypass standard governance for an emergency patch sets a notable precedent for protocol security versus decentralization. RippleX engineers have separately warned that AI could expose critical bugs faster than human developers can respond, highlighting a new frontier in blockchain security dynamics.
