Chain operators should upgrade their nodes ahead of the activation times to a release that contains the Holocene changes and has the activation times for their chains baked in, or set the activation times manually via overrides.

Besides this, several L1 contract updates must be performed, some before and some after Holocene activation. We have prepared an [upgrade script](https://github.com/ethereum-optimism/optimism/tree/develop/packages/contracts-bedrock/scripts/upgrades/holocene) to automate most of the deployments and superchain-ops task generation or Safe multi-sig input bundle generation.
Besides this, several L1 contract updates must be performed, the fault proof contracts should be updated before the Holocene activation. The `SystemConfig` should be upgraded after the Holocene activation.

Chain operators must upgrade their chain's `SystemConfig` to the latest OP Contracts [v1.8.0-rc.2 release](https://github.com/ethereum-optimism/optimism/releases/tag/op-contracts%2Fv1.8.0-rc.2) to utilize the EIP-1559 configurability.

Chain operators need to update their proxy contracts to point to these new implementations. The upgrade script in the monorepo can be used to facilitate the upgrade, please follow the instructions in this [README](https://github.com/ethereum-optimism/optimism/tree/develop/packages/contracts-bedrock/scripts/upgrades/holocene/README.md). Note that it is recommended to upgrade the `SystemConfig` after the Holocene activation. You need to upgrade if you want to reconfigure your EIP-1559 parameters.

### For fault proof enabled chains

Since the Holocene upgrade changes the execution and derivation rules, the version of `op-program` used in the fault proof system has to be upgraded to a version that includes the Holocene activation date for the chain. The `op-program` version used is specified via the `faultGameAbsolutePrestate` setting, deployed as part of `FaultDisputeGame` and `PermissionedDisputeGame` contracts. Additionally, the `MIPS` contract must be upgraded to support additional calls made by the new `op-program`.

The `FaultDisputeGame` and `PermissionedDisputeGame` contracts must be deployed separately for each chain. The `MIPS` contract implementation can be shared by all chains and is deployed at:

* Sepolia: `0x62254B31DBC258aD27472aB08A7920B410734791`
* Mainnet: TBD

Chain operators need to update the `DisputeGameFactory` to use the new `FaultDisputeGame` and `PermissionedDisputeGame` contracts by calling `DisputeGameFactory.setImplementation`. The same upgrade script in the monorepo can be used to facilitate the upgrade, please follow the instructions in this [README](https://github.com/ethereum-optimism/optimism/tree/develop/packages/contracts-bedrock/scripts/upgrades/holocene/README.md).
