# eth\_sendRawTransaction - Ethereum

This method submits a signed transaction to the network. The transaction must be a hex-encoded RLP-serialized signed payload — clients sign transactions locally with their private keys and send only the resulting bytes. Returns the transaction hash immediately if the transaction is well-formed and accepted into the mempool; final mining confirmation is checked separately via `eth_getTransactionReceipt`.

## Parameters

| Parameter           | Type   | Required | Description                                                      |
| ------------------- | ------ | -------- | ---------------------------------------------------------------- |
| `signedTransaction` | string | Yes      | Hex-encoded RLP-serialized signed transaction (with `0x` prefix) |

## Response Parameters

| Parameter | Type   | Description                                           |
| --------- | ------ | ----------------------------------------------------- |
| `jsonrpc` | string | JSON-RPC protocol version ("2.0")                     |
| `id`      | string | Request identifier matching the request               |
| `result`  | string | 32-byte transaction hash of the submitted transaction |

## Use Cases

* **Wallet Transaction Submission**: Submit locally-signed transactions from a wallet to the network
* **MEV Bundle Alternative**: Submit standalone transactions when not going through a private mempool relay
* **Backend Automation**: Systems using hot wallets sign and submit transactions programmatically
* **Bridge Relayer Submission**: Cross-chain bridge relayers submit signed messages as regular transactions

## Error Handling

| Error Code | Message                                    | Description                                                                           |
| ---------- | ------------------------------------------ | ------------------------------------------------------------------------------------- |
| -32602     | Invalid params                             | Signed transaction is not valid hex or the RLP structure is malformed                 |
| -32000     | Nonce too low                              | The transaction's nonce is lower than the sender's current on-chain nonce             |
| -32000     | Insufficient funds for gas × price + value | Sender doesn't have enough ETH to cover the maximum transaction cost                  |
| -32000     | Transaction underpriced                    | Transaction's gas price is below the mempool minimum or below a replacement threshold |
| -32000     | Already known                              | This transaction hash already exists in the mempool                                   |
| -32603     | Internal error                             | Node failed to process the submission                                                 |
