December 2025 monthly summary for celo-org/op-geth focused on strengthening transaction signing robustness by adding a regression test for AccessListTx chain ID validation. The regression test ensures that an incorrect chain ID returns the expected error, reducing the risk of incorrect signing and improving reliability for wallets and validators. This delivery enhances test coverage and fault detection, setting the stage for broader AccessList and chain ID validation improvements. Key commit: 97ba7cc5a7162212a0ae3d988df04fbf9cc75b17.

Delivered comprehensive EigenDA v2 Node Operator Configuration Flags Documentation for celo-org/docs, covering required flags for Mainnet, Alfajores/Baklava, and Celo Sepolia, with concrete flag values and a Docker Compose reference to streamline setup.
