Iron Fish ends network support after uncovering 2019 inflation bug allowing repeated fund spending.

Iron Fish has ceased all remaining network support after discovering a critical inflation bug dating back to 2019. The flaw in its Merkle tree implementation allowed an attacker to repeatedly spend the same shielded funds and withdraw them through the ChainPort bridge. Despite internal and external audits, the vulnerability was missed until unusual activity involving wIRON and ChainPort triggered an investigation. The team patched the bug, published a postmortem, and archived the repository, but did not disclose the total loss or compensation plans. The incident caused a sharp collapse in wIRON's market value, although exact stolen amounts remain undisclosed.

Iron Fish network support cessation is the subject, with Pluang market data providing context. As of Oct 31, 2026 15:51 WIB, 29 of 50 major cryptocurrencies rose and 19 fell. Notable movers include BAL at Rp16.297 (+11.14%), EOS at Rp12.649 (+8.13%), and ENJ at Rp434 (+5.32%) with a 65% sell order activity.
