Iron Fish withdraws network support after 2019 inflation bug enabled repeated double-spending and bridge outflows
first published 2026-10-31T10:00:00Z
Iron Fish said it is ending all remaining network support after finding an inflation bug from early 2019 that allowed an attacker to repeatedly spend the same shielded notes and move funds out through the ChainPort bridge. The team said the flaw came from its Merkle tree and nullifier logic, audits missed it, and it has issued a patch and postmortem. It did not disclose the amount created or any compensation plan, while traders reported a sharp collapse in the wIRON pair on Base.
