XRP Ledger overflow bug could have minted 18 trillion XRP

A bug in the XRP Ledger's payment engine sat undetected for 11 years and could have minted roughly 18 trillion XRP — about 180 times the token's 100 billion supply — in a single transaction. The XRP Ledger Foundation disclosed the flaw on October 9; the fix shipped September 25 in xrpld 3.4.1, and no evidence of exploitation on a live network was found.
