# eth_sendRawTransaction | Optimism

> Optimism API method eth_sendRawTransaction allows for the submission of a pre-signed transaction to the Optimism network for broadcast.

Optimism API method `eth_sendRawTransaction` allows for the submission of a pre-signed transaction to the Optimism network for broadcast. This method is crucial for executing transactions from externally owned accounts without relying on Optimism node wallets for signing.

## Parameters

* `signedTransactionData` — the signed transaction data in hexadecimal format. This data includes the transaction details such as nonce, gas price, gas limit, to address, value, data, and the signature.

## Response

* `result` — the hash of the successfully submitted transaction.

## Use case

The `eth_sendRawTransaction` method is essential for:

* Wallets and other applications that sign transactions offline or in a secure environment and then submit them to the network.
* Services that batch or automate transaction submissions.
* Users and developers requiring control over the transaction signing process for security reasons.
