# debug\_batchSendRawTransaction - Ethereum

Example code for the debug\_batchSendRawTransaction JSON RPC method. Сomplete guide on how to use debug\_batchSendRawTransaction JSON RPC in GetBlock Web3 documentation.

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

| ---------- | ---------------------------------- | -------------------------------------------------------------------------------- |
| -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 |
