Query a contract's runtime bytecode.

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

Request parameters

Position	Type	Required	Description
params[0]	string	yes	Contract address (20-byte hex or base58check)
params[1]	string	yes	Block tag, only latest is supported

curl -X POST https://nile.trongrid.io/jsonrpc \
  -H 'Content-Type: application/json' \
  -d '{"jsonrpc":"2.0","method":"eth_getCode","params":["0x9ff8fc48fb114ccd5bbdc24a86f0c73082f08825","latest"],"id":1}'

Response

Hex-encoded SmartContractDataWrapper.runtimecode (with 0x prefix). Returns 0x if the address is not a contract or the contract does not exist.

The example below is the real response captured from the Nile testnet curl above (this address is an ERC-1167 minimal proxy clone with the implementation contract embedded mid-bytecode):

{
  "jsonrpc": "2.0",
  "id": 1,
  "result": "0x363d3d373d3d3d363d73337d2c535241e1bc38e9c1fc2181843aef31dfaa5af43d82803e903d91602b57fd5bf30000000000000000000000003804c9c36c304d3d3d40bcc1a7c8d47591eda1b0"
}

Error responses

Trigger	Code	message

params[1] is a valid hex number	-32602	QUANTITY not supported, just support TAG as latest
