# eth\_sendRawTransaction

{% hint style="info" %}

`eth_sendRawTransaction`  是BlockRazor 為 Robinhood Chain 提供的交易發送接口，用户可通过该方法將已簽名的原始交易低延迟發送到鏈上，目前支持HTTPS协议。

### Robinhood Chain是什么 <a href="#what-is-robinhood-chain" id="what-is-robinhood-chain"></a>

Robinhood Chain 是一個以太坊 Layer 2 網絡，基於 Arbitrum 構建，專為 RWA 優化，包括股票和 ETF 等資產。它支持全天候的鏈上交易以及用戶自主托管，讓用戶無需依賴傳統金融中介即可直接在區塊鏈上持有、交易和管理資產。

### Benchmark

我們將測試客戶端部署於AWS的法蘭克福、俄亥俄和日本地區，向對應地區的 BlockRazor 端點和官方 RPC 端點發送 50 組 nonce 相同的交易。每組交易除接收地址（用於區分發送通道）外，其餘所有參數均保持完全一致。

我們通過比較兩種通道最終成功上鏈交易的佔比來評估性能，上鏈佔比越高，代表交易傳播和執行速度越快。基準測試結果如下。

<table><thead><tr><th width="157.453125">地區</th><th>BlockRazor上鍊率</th><th>Robinhood上鏈率</th></tr></thead><tbody><tr><td>法蘭克福</td><td>88%</td><td>12%</td></tr><tr><td>俄亥俄</td><td>50%</td><td>50%</td></tr><tr><td>日本</td><td>96%</td><td>4%</td></tr></tbody></table>

## 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/rpc/robinhood-chain/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.
