# BSC Block Builder Send Bundle API

瞭解 BlockRazor BSC Block Builder的Send Bundle API的接口說明、請求參數、請求示例和返回示例

### 接口說明

本接口用於接收用戶提交的bundle，方法名為`eth_sendBundle`。 

BlockRazor MEV服務的區塊構建算法傾向於向BlockRazor Builder EOA轉賬原生代幣（BNB）數量更多的bundle，當前BlockRazor Builder EOA地址為

```
0xc7d4187cBda07F4b5be04418B9723b5faF65dB5C
```

bundle中交易的gas price需不小於BSC Validator要求的最低標準（當前為0.05 gwei）。

### 請求參數

<table data-search="false"><thead><tr><th width="163">參數</th><th width="85.73046875">必選</th><th width="136">格式</th><th width="124">示例</th><th>描述</th></tr></thead><tbody><tr><td>txs</td><td>是</td><td>array[hex]</td><td>["0x…4b", "0x…5c"]</td><td>經過簽名的raw transaction列表</td></tr><tr><td>maxBlockNumber</td><td>否</td><td>uint64</td><td>39177941</td><td>該bundle有效的最大區塊號，默認為當前區塊號+100</td></tr><tr><td>minTimestamp</td><td>否</td><td>uint64</td><td>1710229370</td><td>期望bundle有效的最小Unix秒級時間戳</td></tr><tr><td>maxTimestamp</td><td>否</td><td>uint64</td><td>1710829390</td><td>期望bundle有效的最大Unix秒級時間戳</td></tr><tr><td>revertingTxHashes</td><td>否</td><td>array[hash]</td><td>["0x…c7", "0x…b7"]</td><td>允許revert的交易哈希列表</td></tr><tr><td>noMerge</td><td>否</td><td>bool</td><td>false</td><td>bundle merge可提升區塊價值，加快bundle上鏈速度，如不設置則默認為false（允許bundle merge）</td></tr><tr><td>positionFirst</td><td>否</td><td>bool</td><td>false</td><td>嚴格按優先費用對bundle排序。若該項设置为false（默認），則到達较晚的bundle可能被添加至區塊尾部区域，以保證其在當前區塊成功上鏈。</td></tr></tbody></table>

### 請求示例

```

{% endtab %}
{% endtabs %}

### 返回示例

```json
{
 "jsonrpc":"2.0",
 "id":"1",
 "result":"0xa06b……f7e8ec" //bundle哈希
}‍
```

```json
{
  "jsonrpc":"2.0",
  "id":"1",
  "error":{
    "code":-38000,
    "message":"the maxBlockNumber should not be smaller than currentBlockNum"
    }
}

# 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 by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.blockrazor.io/tc/transaction-submission/block-builder/send-bundle.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
