# debug\_batchSendRawTransaction - Ethereum

This method submits an array of signed raw transactions to the network in a single call. Higher throughput than N separate `eth_sendRawTransaction` calls — the node batches mempool insertion. Returns an array of results per transaction. Useful for high-frequency workflows and MEV searchers submitting multiple related transactions.

## Parameters

| Parameter            | Type            | Required | Description                                             |
| -------------------- | --------------- | -------- | ------------------------------------------------------- |
| `signedTransactions` | array of string | Yes      | Array of hex-encoded RLP-serialized signed transactions |

## Response Parameters

| Parameter | Type            | Description                                                                          |
| --------- | --------------- | ------------------------------------------------------------------------------------ |
| `jsonrpc` | string          | JSON-RPC protocol version ("2.0")                                                    |
| `id`      | string          | Request identifier matching the request                                              |
| `result`  | array of string | Array of 32-byte transaction hashes, in the same order as the submitted transactions |

## Use Cases

* **MEV Bundle Submission**: Submit multiple related transactions in one call for lower total latency
* **Batched Hot-Wallet Flows**: Automated systems drain-empty and refill wallets with sequential nonces atomically
* **High-Throughput Sequencer Feeds**: Bridge relayers submitting batches of L2 → L1 messages

## Error Handling

| Error Code | Message                            | Description                                                                      |
| ---------- | ---------------------------------- | -------------------------------------------------------------------------------- |
| -32601     | Method not found                   | `debug` module not enabled — Dedicated Node tier required                        |
| -32602     | Invalid params                     | One or more transactions have malformed hex or invalid RLP structure             |
| -32000     | Nonce too low / Insufficient funds | One or more transactions fail mempool checks — check per-tx errors in error data |

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.getblock.io/api-reference/ethereum-eth/debug_batchsendrawtransaction-ethereum.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
