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.
Blast has L2-specific yield and gas-revenue mechanics. Network setup pages should not be treated as financial guidance.
