## Key takeaways

- A validation flaw tied to Pirate Chain's Ironwood upgrade allowed an attacker to mint around 39.8 million ARRR, roughly 20% of the token's total supply.
- Pirate Chain's team proposed rolling the network back to its state at 20:00 UTC on October 14, 2026, and asked users not to move funds.
- NonKYC flagged deposits tied to the exploit, restricted them and blocked withdrawals to limit further risk.

A validation flaw in [Pirate Chain](https://akta.pro/company-profiles/000gybg/pirate-chain)'s Ironwood upgrade allowed an attacker to mint around 39.8 million ARRR, roughly 20% of the privacy coin's total supply. [Crypto Briefing](https://cryptobriefing.com/pirate-chain-exploit-arrr-rollback/) reported that the network is still running while the team proposes rolling it back to October 14, 2026, 20:00 UTC. Users were told not to move funds.

## How the Pirate Chain Exploit Unfolded

The vulnerability surfaced on October 14, 2026, and traced back to two separate validation failures connected to Ironwood, a network upgrade Pirate Chain activated on October 3. The freshly minted tokens were moved quickly into the Sapling shielded pool, the part of the network where balances and transfers are hidden by cryptography. Pirate Chain's development team acknowledged that the shielded nature of these transactions could make it harder to trace where the illicit coins went next.

[NonKYC](https://akta.pro/company-profiles/002e3a5/nonkyc) flagged deposits tied to the exploit, restricted them and blocked withdrawals to limit further risk. Pirate Chain's instructions were blunt: users were asked not to move funds, and exchanges and mining pools were advised to voluntarily pause operations. The proposed fix is a blockchain rollback reverting the network to its state as of 20:00 UTC on October 14, with the goal of discarding every block produced after the exploit window. The team said there was no indication that Pirate Chain's notary keys or its zk-SNARKs cryptography had been compromised.

[Thedefiant](https://thedefiant.io/news/hacks/pirate-chain-says-exploit-created-39-8-million-arrr) reported that Pirate Chain said the exploit created 39.8 million ARRR, that the network remains operational, and that users have been asked not to move funds while developers work on recovery.

## Pirate Chain's Supply and Notarization Setup

According to akta.pro [company records](https://akta.pro/company-data), Pirate Chain has a circulating supply of approximately 196 million ARRR out of a total supply of just over 200 million tokens, with around 90% of total supply already mined. The project targets a maximum supply of 200 million ARRR, and 100% of its transactions use zk-SNARKs, making shielding mandatory rather than optional. Pirate Chain originated as a Komodo Platform asset chain and continues to use Komodo's Delayed Proof of Work service, now provided by Komodo Classic, which notarizes its transactions to Litecoin for 51% attack protection. The same records show block generation time of approximately 60 seconds and a block reward halving every 388,885 blocks, roughly every 270 days.

## What Comes Next for Pirate Chain

The rollback requires coordination among exchanges, miners and node operators. Pirate Chain's team has yet to state when exchanges and mining pools will resume normal operations, and it has not published a full breakdown of the two validation failures behind Ironwood. The Ironwood upgrade had been live for only 11 days when the flaw was found.
