Base

Fault proofs are coming to Base mainnet on October 30th, marking a key milestone on the path to decentralization

This means anyone can monitor and permissionlessly challenge invalid withdrawals, removing the need for a trusted third party

The Base team has been collaborating closely with @Optimism to bring fault proofs to Base and ensure a safe upgrade

Withdrawals on Base that are pending when the upgrade occurs will need to be re-proven
