# Robinhood Chain Transaction Sending in Plain Text

`Send in Plain Text` 用於在 Robinhood 上發送已簽名的交易，與 [eth\_sendRawTransaction](/tc/transaction-submission/transaction-sending/robinhood-chain/eth_sendrawtransaction.md) 方式相比，它提供了一種更精簡、更迅速的交易提交途徑。

* 繞過 CORS 預檢： 它消除了通常由 OPTIONS 預檢請求所引起的延遲。
* 純文本而非 JSON： 採用簡單的純文本傳輸，避免了與解析 JSON 相關的計算負擔。此外，由此產生的較小數據包尺寸有助於縮短網路傳輸時間並降低成本。

`Send in Plain Text` 的以上特性更適合擁有全球用戶的前端交易應用項目。

## 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/transaction-sending/robinhood-chain/eth_sendrawtransaction/send-in-plain-text.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.
