# eth\_sendRawTransaction - ARC

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 broadcasts a signed transaction to the Arc network for execution. It is the primary method for submitting any state-changing operation — USDC transfers, smart contract calls, contract deployments, and FX engine swaps. Gas is paid in USDC.

## Parameters

| Parameter    | Type   | Required | Description                                                                                         |
| ------------ | ------ | -------- | --------------------------------------------------------------------------------------------------- |
| signedTxData | string | Yes      | The signed transaction data (hex), produced offline by a signer such as ethers.js, viem, or web3.py |
