Setup caution

Avalanche distinguishes C-Chain chain ID from other Avalanche network identifiers. Confirm the RPC path includes /ext/bc/C/rpc before configuring EVM tooling.

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/avalanche-c-chain/#copy-ready-config.
