# Dedicate Connection

Dedicate Connection 是一項面向低時延交易提交場景的專用連接服務，支持將客戶端與服務端部署在同機房，並向客戶開放 Block Builder 的 `ip:port` 進行裸調。相比通過 HTTP 域名入口提交交易，Dedicate Connection 提供的是一條更直接、更底層的 Builder 接入方式，盡可能減少共享入口、代理層和額外封裝帶來的開銷，縮短客戶端到 Builder 的實際網絡路徑，從而提升提交鏈路的穩定性、確定性和可控性。

### 和 Fast Submit 的區別

Dedicate Connection 和 Fast Submit 都用於提升向 BSC Block Builder 提交交易的效率與穩定性，但定位不同。Fast Submit 是優化後的標準接入方案，開發者通常只需要使用專屬 HTTP 域名，即可通過更直接的網絡路徑、優化後的跨區域鏈路以及服務端請求處理優化，獲得更快、更穩的提交體驗，適合希望在較低接入成本下提升提交鏈路質量的場景。

Dedicate Connection 則更強調最短路徑和鏈路控制，開放 Builder 的 ip:port，支持客戶端與服務端同機房部署，適合對時延極度敏感、希望自行控制底層連接策略、並具備較強基礎設施能力的團隊。

### 價格

$1500 / 月，請前往[訂閱](https://blockrazor.io/#/pricing)頁面採購，訂閱完成後請[聯繫](https://discord.com/invite/qqJuwRb8Nh)我們開始接入

### 接入方式

1. 前往[訂閱](https://blockrazor.io/#/pricing)頁面採購，訂閱完成後請[聯繫](https://discord.com/invite/qqJuwRb8Nh)我們
2. 獲取 Block Builder ip:port，並按要求完成機房部署或網絡連通準備。
3. 完成後，客戶端即可直接連接對應地址進行請求發送，並在實際部署環境中測試時延、穩定性和提交效果。

### 注意事项

Dedicate Connection 提升的是客戶端到 Builder 的連接質量，不保證交易一定會被打包。最終結果仍然會受到市場競爭、Builder 處理策略、區塊空間、鏈上擁堵以及交易本身質量等因素影響。此外，Dedicate Connection 更適合對網絡路徑和連接控制有明確要求的場景，接入前建議結合自身部署條件、請求模式和運維能力進行評估。

## 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/block-builder/dedicate-connection.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.
