A note to canonical bridge providers: There will be a contract upgrade on Base Mainnet on April 9th between 11am-12pm EDT, which will invalidate pending withdrawals.
As seen in previous upgrades, users will need to submit a second proof transaction post-upgrade to complete withdrawals if they are still pending at the time of the upgrade on April 9th.
This is a standard and scheduled upgrade, and no funds are at risk alongside this change.
All funds will be available at the end of the maintenance period.
