XRP Ledger Skips Its Own Amendment Vote for First Time to Patch Critical Bug

The XRP Ledger bypassed its amendment voting process for the first time in over a decade, shipping emergency patch xrpld 3.4.1 on September 25, three days after Veria AI researchers reported the flaw. A 64-bit integer overflow in the payment engine, present since 2015, could have let an attacker mint unlimited XRP. The 100 billion supply cap remains intact and the bug was never exploited.

• The 64-bit overflow flaw sat in production code since 2015
• Patch xrpld 3.4.1 shipped September 25, disclosed October 9
• XRP supply stays at roughly 99.986 billion, cap untouched
• Standard validator voting requires at least two weeks
