EVM RPC Endpoints

Below is a list of EVM-RPC endpoints provided by default on a Sei RPC node. Your RPC provider may offer slightly different/extended specifications.

All endpoints are in the form of JSON-RPC and share the following request/response structure:

  • Request
    • HTTP method: always "GET".
    • header: accept: application/json
    • header: content-type: application/json
    • body (JSON):
    • id: an arbitrary string identifier.
    • jsonrpc: always "2.0".
    • method: endpoint name (e.g. "eth_sendRawTransaction").
    • params: an array that differs from endpoint to endpoint.
  • Response
    • body (JSON):
    • id: the same identifier in request.
    • jsonrpc: always "2.0".
    • result: an object that differs from endpoint to endpoint.

Send Transactions
