Pirate Chain reported that a validation flaw allowed the creation of around 39.8 million ARRR, roughly 20% of the token's total supply at the time. The vulnerability surfaced on October 14, 2026. It was tied to the Ironwood upgrade. The team attributed the issue to validation errors and said it had no indication that zk-SNARK cryptography or notary keys were compromised. Exchanges and network participants restricted activity while the team investigated. The team proposed a rollback to 20:00 UTC on October 14.

Key points

  1. Pirate Chain developers disclosed that a validation flaw created approximately 39.8 million unauthorized ARRR.
  2. The unauthorized tokens were substantial relative to Pirate Chain's existing supply.
  3. Privacy features made it difficult to trace the affected funds once they entered shielded transaction pools.
  4. Developers attributed the issue to implementation and validation errors, not a defeat of zero-knowledge cryptography.
  5. Exchanges and network participants imposed precautionary restrictions while the team investigated.

Why it matters

The exploit raises immediate questions about Pirate Chain's recorded supply and trading access, because shielded transactions limit outsiders' ability to trace the unauthorized ARRR. Exchanges and network participants restricted activity while the team investigated.

What's unclear

It is not clear where the unauthorized ARRR moved after entering shielded transaction pools.
Whether the proposed rollback to 20:00 UTC on October 14 will be executed cleanly is not yet known.
