How to read this RPC listing
Treat this as a source-cited reference for configuring wallets, local tooling, or documentation examples. Main.net does not operate this RPC endpoint and does not make uptime, latency, privacy, or support guarantees for it.
Optimism labels public RPC URLs as rate-limited. Use them for development or light checks, not production-grade app reliability.
