Important

This is a required upgrade if you are operating a node for an OP Chain that will be activating Jovian

• Jovian activates on the Sepolia Superchain Wed 12 Nov 2025 16:00:01 UTC (1762963201)
• Jovian will optimistically activate on the Mainnet Superchain Tue 25 Nov 2025 16:00:01 UTC (1764086401)

as it contains the Jovian activation on these dates.

This PR enumerates the chains which will activate Jovian at the timestamps above. It is mandatory to upgrade nodes for those chains before the corresponding dates above.

🤝 The corresponding mandatory op-geth release is v1.101603.3.

Chain operators also need to upgrade op-conductor to op-conductor/v0.9.0.

Warning

Any chain currently using the operator fee feature should adjust their scalars before Jovian activates.
