  • Mainnet Superchain withdrawal pause test will happen May 14th 2025.
The Optimism Collective will be testing improved incident response features on the Sepolia Superchain.

​
What’s happening

  1. During this exercise, the privileged GUARDIAN address will call the pause function on the SuperchainConfig.
  2. Members of the Optimism Collective’s security team will ensure that the pause is executed correctly and the incident response improvements worked as intended.
  3. Then the unpause function will be called to resume normal operations.
To learn more about this functionality, please refer to this documentation. This functionality is important for the security of the Superchain and should be understood by Chain Operators, users, and especially for centralized exchanges and third-party bridge operators. Please note that this will not effect any L1-to-L2 deposit transactions or L2 transactions. No action is required from users or operators.
