The Holocene Hard Fork will activate on the OP Superchains (Base and Optimism) for Sepolia testnet on Tue Nov 26 @ 15:00:00 UTC, and brings a number of improvements to the protocols. You can find the complete list of changes here:
Holocene block derivation: a set of changes that render the derivation pipeline stricter and simpler, improving worst-case scenarios for the Fault Proof System and Interoperability.
EIP-1559 configurability: The elasticity and denominator EIP-1559 parameters become configurable via the SystemConfig L1 contract, allowing the gas target and gas limit to be configured independently.
MIPS contract upgrade: Updates to support additional calls made by the new op-program version.
We do not expect any downtime as a result of the hard fork. If you have any questions, please contact your CSM (Customer Success Manager).
