Important note

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

Main.net is an independent reference site and is not affiliated with Coinbase or Base. Always verify important details in the source documentation before moving funds.

Treat the public RPC endpoint as a setup reference, not as a production reliability promise. Teams running apps on Base should compare monitored provider endpoints, request limits, archive access, alerting, and fallback behavior before shipping user-facing flows.

Use the status page copy path for the current reviewed config: /status/base/#copy-ready-config.
