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://sapphire.oasis.io

# Expected chain ID: 23294 / 0x5afe

Safety note

Oasis documentation warns that public RPC endpoints are points of trust and may be rate-limited, censored, or man-in-the-middle targets. Run dedicated infrastructure for sensitive use.

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