# eth\_sendRawTransaction - Blast

Example code for the eth\_sendRawTransaction JSON-RPC method. Complete guide on how to use eth\_sendRawTransaction JSON-RPC in GetBlock Web3 documentation.

This method submits a signed, serialized transaction to the network for inclusion. It is the only write method on a public endpoint: the transaction must be signed client-side before submission.

## Parameters

| Parameter             | Type   | Required | Description                                |
| --------------------- | ------ | -------- | ------------------------------------------ |
| signedTransactionData | string | Yes      | 0x-prefixed RLP-encoded signed transaction |
