Minimal JSON-RPC identity check. This verifies the endpoint-reported chain ID only, not uptime or production suitability.

curl -s -X POST \
  -H 'content-type: application/json' \
  --data '{"jsonrpc":"2.0","id":1,"method":"eth_chainId","params":[]}' \

Safety note

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

Main.net is an independent reference site. It does not operate this chain, custody assets, execute transactions, or provide investment advice.
