# Send Bundle

### 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0x1266C6bE60392A8Ff346E8d5ECCd3E69dD9c5F20。\
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）。

# 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.blockrazor.io/tc/transaction-submission/block-builder/send-bundle.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.
