Pirate Chain said in an Oct. 15 X post that it had identified an exploit tied to Ironwood turnstile supply accounting and planned to roll the chain back to Oct. 14, 2026 at 1:00 PM Pacific Time. The project also said exchanges had been notified to temporarily suspend ARRR deposits and withdrawals, while the widely cited 39.8 million ARRR illicit-mint figure remains attributable to the current news report rather than a fully inspected primary incident accounting.

What Pirate Chain said happened on October 15

Pirate Chain's official X-account excerpt said it had identified an exploit in a new transparent layer related to Ironwood turnstile supply accounting and that developers would roll the chain back to Oct. 14, 2026 at 1:00 PM Pacific Time. In the same incident message, the project told users not to send or receive funds and to avoid using wallets while the issue was being resolved, adding that further details would follow after the rollback and investigation.

That makes the clearest current development an emergency rollback response, not a completed fix. The supplied current news report adds the broader allegation that about 39.8 million ARRR was illicitly minted through two transaction-validation vulnerabilities and moved into the shielded pool, but those details were not matched here by a fully inspected primary incident report or on-chain accounting.

What transfer suspensions are actually supported

Pirate Chain said exchanges had been notified to temporarily suspend ARRR deposits and withdrawals, and MEXC separately posted that it had suspended ARRR transfers at the project's request. That supports a real transfer-freeze response, but it does not establish that every exchange handling ARRR had already implemented the same action.

For users, the practical point is that ARRR transfer status should be treated as venue-specific until more named exchange notices or reopenings are published. The supplied material also says dPoW operators temporarily halted transaction validation, but no direct operator notice was provided here to show the scope of that halt or the condition for resumption.

How the exploit was framed and what comes next

The supplied official excerpts tie the exploit to a new transparent layer related to Ironwood turnstile supply accounting, and earlier Pirate Chain materials place the Ironwood rollout in 2026, with activation said to be live by Oct. 3. That context supports describing this as an Ironwood-era exploit response rather than a generic long-running ARRR chain issue.

What is still missing is a full technical postmortem. The available material does not establish block heights, affected software versions, transaction IDs, whether the reported 39.8 million ARRR figure is complete, or whether any allegedly illicitly minted coins can be reversed or neutralized beyond the stated rollback plan. The next concrete milestone is therefore a project update confirming whether the rollback was completed and when normal wallet and exchange activity can safely resume.
