Wallet and tooling caution

A matching chain ID helps software select the right network, but it does not prove an RPC endpoint is official, private, reliable, or safe. Main.net is an independent reference site and is not affiliated with the listed networks unless explicitly stated.

Show chain type clearly so users do not confuse L1, L2, and sidechain assumptions.
