eth_chainId - Ethereum

Recalls the new configured chain id, which value will come in handy for replay-protected transaction realization as in EIP-155 suggestions

How to Use the eth_chainId Method

The received chain ID must fit the information in the actual known head block. It ensures that the user can apply the information for transactions’ assignment.

Parameters

No parameters.

What you receive

QUANTITY - large integer of the current chain id.

Sample

Here is a typical appliance example.

Call

curl https://eth-mainnet.rpcfast.com/?api_key=<key> \
    -X POST \
    -H "Content-Type: application/json" \
    -d '{"jsonrpc":"2.0","method":"eth_chainId","params":[],"id":1}'

Outcome

{"jsonrpc":"2.0","id":1,"result":"0x1"}
