## `broadcastRawTransaction`

### Signature

```solidity
function broadcastRawTransaction(bytes calldata data) external;
```

### Description

Takes an RLP-encoded signed transaction, executes it against the current EVM state, and, when a broadcast is active, queues the exact signed payload for on-chain submission.

The signer is recovered from the transaction signature and used as the sender for execution. This makes it possible to replay transactions that were signed elsewhere, for example pre-signed permits, transactions signed by hardware wallets, or presigned emergency transactions.

The cheatcode reverts if the bytes cannot be decoded into a valid signed transaction or the signer cannot be recovered.

### Parameters

| Parameter | Type    | Description                          |
|-----------|---------|--------------------------------------|
| `data`    | `bytes` | The RLP-encoded signed transaction   |

### Examples

```solidity [script/BroadcastRaw.s.sol]
function run() external {
    // A transaction signed offline, e.g. exported from another tool.
    bytes memory signedTx = vm.envBytes("SIGNED_TX");

    vm.startBroadcast();
    vm.broadcastRawTransaction(signedTx);
    vm.stopBroadcast();
}
```

### Gotchas

:::note
The transaction is executed against the current state, so the recovered sender must have a matching nonce and a sufficient balance, exactly as if the transaction were submitted to a node.
