A checklist for things to check before merging a chain PR.
- If the PR contains explorers claim to adhere to EIP3091 - check if they really do.
- Check if a PR does not remove a chain - chains cannot be removed - only deprecated (to protect from replay attacks)
- Check if a PR does not assign a chainID to a newer chain (something like ethereum-lists#1750)
Please also make sure to go from oldest PR to newest.
If anyone has ideas on how to automate these things in CI - PRs welcome!
