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://bsc-dataseed.bnbchain.org

# Expected chain ID: 56 / 0x38

Safety note

BNB Chain lists several public RPC endpoints. Treat public dataseed endpoints as convenience infrastructure and use dedicated providers for production traffic.

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