XRP Ledger maintainers disclosed and patched a critical integer overflow in the payment engine that could have let an attacker mint counterfeit XRP far beyond the token's total supply. A researcher reported the bug through the bug bounty program in September; it had existed since the payment engine was written in 2015, unnoticed because no ordinary payment triggers it, and the ledger's safety check used the same flawed arithmetic. The fix shipped in version 3.4.1 on Sept. 25, with over 80% of trusted validators running it that day, bypassing the usual two-week amendment process. The team says there is no evidence the bug was exploited. XRP traded at $1.38 on Monday, down 1.6% over 24 hours, the worst performance among major cryptocurrencies, and down 9.4% over seven days.
