OP Labs announced the introduction of a proposed protocol upgrade to enhance the Superchain's security incident response capabilities. This upgrade is based on insights collected through comprehensive simulated event responses and industry expert opinions, and aims to enhance the resilience of the Superchain after its launch.

OP Labs stated that this is a security upgrade specifically for L1 smart contracts, which should not affect nodes or executing client software, and should not require node operators to upgrade their nodes or take any action in response to this upgrade. Users should not be affected either.
