# realtime\_sendRawTransaction

Submits a signed transaction and returns the receipt directly once the transaction is executed — no polling required. This is a drop-in replacement for `eth_sendRawTransaction` that eliminates the need to poll `eth_getTransactionReceipt`. The method times out after 10 seconds if the transaction has not been executed.

## Parameters

| Position | Type   | Required | Notes                          |
| -------- | ------ | -------- | ------------------------------ |
| `0`      | `Data` | Yes      | Hex-encoded signed transaction |

## Returns

A transaction receipt object on success:

| ----------------- | ----------------- | ------------------------------------------------ |

| `from`            | `Data` (20 bytes) | Sender address                                   |
| `to`              | `Data` (20 bytes) | Recipient address (`null` for contract creation) |
| `gasUsed`         | `Quantity`        | Gas consumed by the transaction                  |
| `status`          | `Quantity`        | `0x1` for success, `0x0` for revert              |
| `logs`            | `Log[]`           | Event logs emitted during execution              |

## Errors

| Code     | Cause                                                                       | Fix                                              |
| -------- | --------------------------------------------------------------------------- | ------------------------------------------------ |
| `-32000` | `realtime transaction expired` — transaction not executed within 10 seconds | Fall back to polling `eth_getTransactionReceipt` |
