Scheduled
OP Superchains will undergo a Hard Fork on 9th January 2025 @ 18:00 UTC, and brings a number of improvements to the protocol. You can find the list of changes here:
https://gov.optimism.io/t/upgrade-proposal-11-holocene-network-upgrade/9313

- Holocene block derivation: a set of changes that render the derivation pipeline stricter and simpler, but also improve worst-case scenarios for Fault Proofs and Interoperability.
- EIP-1559 configurability: The elasticity and denominator EIP-1559 parameters become configurable via the SystemConfig L1 contract, allowing gas target and gas limit to be independently configured.
- 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).
