Scheduled - The Isthmus upgrade will occur on Base Sepolia Testnet on Thursday, April 17th at 16:00:00 UTC. All Base Sepolia Testnet node operators must update to v0.12.0 (Geth) or v0.12.1 (Reth) before this activation timestamp or they will halt when the network activates Isthmus.

Geth: https://github.com/base/node/releases/tag/v0.12.0
Reth: https://github.com/base/node/releases/tag/v0.12.1

Scheduled - On April 14th, for approximately one hour at 15:30 UTC, the Optimism Collective will be conducting a canonical bridge withdrawal pause on testnets across the Superchain, including Base Sepolia testnet. Base mainnet, including canonical bridges on Base mainnet, will remain fully operational and completely unaffected during this pause. There is also no risk to user funds.

Testnet users will be completely unaffected unless actively attempting to withdraw using the canonical bridge on Base Sepolia testnet during the pause window. All other testnet activity will continue as usual.

For more information about the pause, see:

Scheduled - 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.
