eth_coinbase

Returns the etherbase address (Ethereum compatibility; Tron has no native PoW coinbase concept).

• Source: framework/src/main/java/org/tron/core/services/jsonrpc/TronJsonRpcImpl.java#getCoinbase
• Ports: FullNode 8545 / Solidity 8555

Request parameters

None.

curl -X POST https://nile.trongrid.io/jsonrpc \
  -H 'Content-Type: application/json' \
  -d '{"jsonrpc":"2.0","method":"eth_coinbase","params":[],"id":1}'

Response

The string returned by wallet.getCoinbase(). Only returns a value when the node explicitly configures node.etherbase. With it configured, the response looks like:

{ "jsonrpc": "2.0", "id": 1, "result": "0x41a614f803b6fd780986a42c78ec9c7f77e6ded13c" }

Note: the 21 bytes here (0x41 + 20 bytes) is Tron's native address format, different from Ethereum's standard 20 bytes.

Error responses

Trigger	Code	message
Node has no etherbase configured	-32000	etherbase must be explicitly specified

The example below is the real response captured from the Nile testnet curl above (nile.trongrid.io has no etherbase configured, so it goes through the error branch):

{
  "jsonrpc": "2.0",
  "id": 1,
  "error": {
    "code": -32000,
    "message": "etherbase must be explicitly specified",
    "data": "{}"
  }
}
