curl eth_chainId check

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":[]}' \
  https://andromeda.metis.io/?owner=1088

# Expected chain ID: 1088 / 0x440

Safety note

Metis documentation distinguishes public RPCs, private providers, and self-hosted nodes. Use public endpoints for light use and dedicated infrastructure for production.

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