# eth\_sendRawTransaction

`eth_sendRawTransaction` 是 BlockRazor 為 BSC 提供的 Fast 模式交易發送接口，兼容標準 `eth_sendRawTransaction` 調用方式，用於將已簽名交易以更低延遲發送到鏈上。

發往Fast 模式`eth_sendRawTransaction` 的交易不會通過公開 Mempool 廣播，因此在提升發送速度的同時，也能避免交易在公開傳播過程中暴露。

{% hint style="info" %}
`eth_sendRawTransaction`不和訂閱計劃綁定，但每筆交易中需要包含轉賬至0x9D70AC39166ca154307a93fa6b595CF7962fe8e5的tip，金額至少為0.000025 BNB 或 Transaction Fee 的5%
{% endhint %}

## 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/fast/bsc/eth_sendrawtransaction.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.
