### 介紹

Ethereum Private Mempool推送Ethereum的隱私交易流數據。數據流基於SSE協議構建，數據流中的交易統一經脫敏處理，僅披露經授權允許披露的交易數據。

Private Mempool可應用於Backrun、跟單、狙擊等多種場景。

為避免由於網絡波動導致的數據斷流，建議建立重連機制。



### RPC端點

{% hint style="info" %}
請將訂閱bundle的域名與發送bundle的域名保持一致。如訂閱https://jp-ethscutum.blockrazor.xyz/stream，則將bundle發送至https://jp-ethscutum.blockrazor.xyz
{% endhint %}

{% hint style="info" %}
不同地區推送的隱私數據流不同，建議同時訂閱2個端點
{% endhint %}

<table><thead><tr><th width="107.42578125">地區</th><th>端點</th></tr></thead><tbody><tr><td>東京</td><td>https://jp-ethscutum.blockrazor.xyz/stream</td></tr><tr><td>紐約</td><td>https://us-ethscutum.blockrazor.xyz/stream</td></tr></tbody></table>



### Authentication

{% hint style="info" %}
為保護隱私交易，Ethereum Private Mempool採用准入制，如需訂閱請於我們[聯繫](https://discord.com/invite/qqJuwRb8Nh)。
{% endhint %}

```json
curl -X GET \
    -H "Content-Type: application/json" \
    -H "Authorization: Bearer <token>" \
    --data '{}' \
    https://eth.blockrazor.xyz/stream
```

```
https://eth.blockrazor.xyz/stream?token=<token>
```

示例中的\<token>需在註冊BlockRazor後獲取，步驟如下：

1. 前往[https://www.blockrazor.io](https://www.blockrazor.io)，在網頁右上角點擊【註冊】，系統跳轉至註冊頁
2. 在註冊頁輸入郵箱和密碼，點擊【註冊】，系統會向郵箱發送賬戶激活郵件
3. 前往郵箱，查看賬戶激活郵件，點擊賬戶激活鏈接
4. 成賬戶激活，前往登錄，查看賬戶信息，複製auth token
