# eth\_sendRawTransaction - BSC

This method submits a pre-signed transaction to the BNB Smart Chain network for execution. This is the primary method for broadcasting transactions and is essential for any application that needs to send BNB or interact with smart contracts.

## Parameters

| Parameter    | Type   | Required | Description                       |
| ------------ | ------ | -------- | --------------------------------- |
| signedTxData | string | Yes      | The signed transaction data (hex) |
