# eth\_sendRawTransaction

`eth_sendRawTransaction` 是 BlockRazor 為 Base 提供的 Fast 模式交易發送接口，用於將已簽名交易以更低延遲發送到鏈上。目前支持標準 JSON-RPC 風格請求，便於用戶在現有發送邏輯基礎上快速接入。

RPC模式和Fast模式下的`eth_sendRawTransaction` 能力定位存在差異：

* RPC模式的`eth_sendRawTransaction`更適合作為標準發送入口，強調全球多點部署和跨洲專線
* Fast 更適合重點追求單筆交易發送速度和更快進入鏈上執行路徑的場景

{% hint style="info" %}
Fast模式的`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，下限金額至少為0.000003 ETH 或 MaxPriorityFee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/base/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.
