## Response Parameters

| Field  | Type   | Description                                                                     |
| ------ | ------ | ------------------------------------------------------------------------------- |
| result | string | The 32-byte transaction hash, or zero hash if transaction is not yet available. |

## Use Case

The `eth_sendRawTransaction` method is essential for:

* Submitting signed transactions to the network
