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.
Base states its public endpoints are rate-limited and not for production systems. Production apps should use a node provider or run dedicated infrastructure.
