# eth_sendRawTransaction: parameters, returns and CU

> Original page: https://docs.blockvectra.com/en/api/json-rpc/methods/eth_sendRawTransaction/

## Summary

Submit a signed raw transaction.

## Compute Units (CU) and Pricing

CU weight, price and per-chain availability are shown on the method page: https://docs.blockvectra.com/en/api/json-rpc/methods/eth_sendRawTransaction/

## Parameters

| Parameter | Type | Description |
| --- | --- | --- |
| `signedTransactionData` | `DATA` | Signed transaction data as 0x-prefixed hex (the RLP-encoded raw transaction). |

## Returns

- **Type**: `DATA`
- **Description**: Transaction hash as a 32-byte, 0x-prefixed hex string.

## Notes

Receiving a hash only means the node accepted the transaction, not that it is on-chain; confirm success through the receipt.
