}Official docs and source links
Main.net links to source documentation for verification. It does not rank RPC providers or make uptime, latency, privacy, or production reliability claims about public endpoints.
Setup caution
Monad public RPC access is rate-limited. Use official docs and dedicated provider endpoints before deploying production systems.
Always verify important details in official documentation before configuring software that may sign transactions. Use the status page copy path for the current reviewed config:/status/monad/#copy-ready-config.
