TREE NEWS update: The XRP Ledger has patched a decade-old overflow bug in its payment engine that could have allowed an attacker to mint roughly 18 trillion spendable XRP in a single transaction. The flaw has been fixed, closing a vulnerability that threatened the ledger’s supply integrity.
XRP Ledger Patches Bug That Could Have Minted 18 Trillion XRP
The striking part is the scale: the flaw sat in the payment engine for a decade, and the theoretical exploit would have dwarfed the ledger's actual supply — a reminder that supply-integrity assumptions rest on code that can stay latent for years. That matters most for XRPL validators, issuers and anyone valuing tokens whose scarcity is enforced purely at the protocol level. The open question is disclosure: whether other long-dormant code paths receive comparable scrutiny now that this one has surfaced.
