All fault proof enabled chains (both permisionless and fault proof system) need to update their `op-challenger` binary to [`op-challenger/v1.3.1`](https://github.com/ethereum-optimism/optimism/releases/tag/op-challenger%2Fv1.3.1).

The following steps are to update your absolute prestate with new dispute game contracts. **This is absolutely necessary for chains running permissionless fault proofs.** For chains running the Fault Proof System with permissioned games you can skip this section because games will not be played out and the absolute prestate is not used.

The Pectra upgrade changes the derivation rules, permissionless fault proof chains need to upgrade the `op-program` version used in the fault proof system to support these changes. The `op-program` version used is specified via the `faultGameAbsolutePrestate` setting, deployed as part of `FaultDisputeGame` and `PermissionedDisputeGame` contracts.

<Steps>

### Update your `op-challenger`

Update your `op-challenger` binary to [`op-challenger/v1.3.1`](https://github.com/ethereum-optimism/optimism/releases/tag/op-challenger%2Fv1.3.1).

### Verify the new absolute prestate

The absolute prestate is generated with the [op-program/v1.5.0-rc.2](https://github.com/ethereum-optimism/optimism/tree/op-program/v1.5.0-rc.2). You can use this new absolute prestate (`0x035ac388b5cb22acf52a2063cfde108d09b1888655d21f02f595f9c3ea6cbdcd`) for the following chains:
