It would take a change to the chain's own rules. A member of Polygon Labs' validator support team posted a proposal on November 4 for a coordinated hard fork of Polygon PoS that would move about 70.49 million POL, roughly $6.5 million at October 29 prices, out of five attacker-controlled addresses and into recovery wallets controlled by the victims, crypto.news reported. Of that, 46.63 million POL sits at one address tied to the Binance theft and 23.86 million POL at four addresses tied to a separate Polymarket incident, where a third-party provider was compromised the same week. Block producers have already restricted transfers from those addresses, but a block list does not return funds, and without the private keys the only route is rewriting the ledger. The proposal itself calls this an "extreme action that should not be reproduced commonly" and rejects building a standing recovery mechanism, citing worries about permanent authority over user funds. It also alleges the attacker offered validators cash to help move the coins. Discussion was set for Polygon's governance call on November 5 at 14:30 UTC; if approved, testing on the Amoy testnet could take about two weeks, and nodes that fail to upgrade could end up on a split chain. No activation block has been chosen.
