## Response Message

`SmartContract`

| Field             | Type   | Description                      |
| ----------------- | ------ | -------------------------------- |
| contract\_address | bytes  | The contract address             |
| origin\_address   | bytes  | The deployer address             |
| abi               | ABI    | The contract ABI, when available |
| name              | string | The contract name                |
| bytecode          | bytes  | The contract's deployed bytecode |

## Use Cases

* **ABI Retrieval**: Read a contract's ABI to encode calls
* **Contract Inspection**: Read a contract's name and deployer
* **Bytecode Reads**: Retrieve deployed bytecode
* **Verification**: Confirm a contract exists at an address
