# 集成RPC

{% hint style="info" %}
BlockRazor RPC面向所有用户开放，無需采购服务或申请Auth
{% endhint %}

### 端點

<table><thead><tr><th width="165.31640625">端點類型</th><th>URL</th></tr></thead><tbody><tr><td>通用RPC</td><td>https://bsc.blockrazor.xyz</td></tr><tr><td>項目默認RPC</td><td>https://bsc.blockrazor.xyz/&#x3C;rpc_id></td></tr><tr><td>項目自定義RPC</td><td>https://&#x3C;custom_domain>.bsc.blockrazor.xyz</td></tr></tbody></table>

### 如何將BSC RPC集成到項目中

#### 1. 配置RPC

1. 在[blockrazor.io](https://blockrazor.io/)完成註冊並登錄控制台
2. 在RPC模塊下點擊RPC配置頁，查看專屬RPC的配置信息
3. 點擊 **更新**，進入配置更新頁，根據需求調整參數，參數含義見如下表格

<table><thead><tr><th width="183">參數</th><th>含義</th></tr></thead><tbody><tr><td>默認RPC URL</td><td>每個賬號默認自動生成1個Ethereum RPC和1個BSC RPC。默認RPC由系統自動生成，URL無法修改</td></tr><tr><td>自定義RPC URL</td><td>自定義RPC URL支持修改三級域名，可用於向項目的終端用戶推廣，引導用戶在錢包中添加自定義RPC</td></tr><tr><td>披露</td><td>系統默認將交易的hash和logs分享給Searcher，分享字段越多獲得返利的可能性越大，請在評估交易隱私披露必要性後謹慎操作</td></tr><tr><td>返利地址</td><td>默認返利地址為tx.origin，即會將返利返給交易的發起者，可修改為固定返利地址（EOA）</td></tr><tr><td>Revert保護</td><td>默認開revert保護，如交易在實際執行中發現revert，則不會納入區塊。為確保快速納入區塊，建議在以太坊的交易中設置一定的priority fee。</td></tr></tbody></table>

4. 點擊  **確認**，系統將實時更新RPC配置

#### 2.集成RPC

1. 找到配置文件或代碼：打開項目工程，在DApp項目中找到配置RPC節點的文件或代碼段。這可能是一個配置文件，如.env、config.js、truffle-config.js等，或者是直接在代碼中硬編碼
2. 修改RPC URL：將配置文件或代碼中的RPC URL修改為项目默认RPC或项目自定义RPC
3. 測試連接：更改後，在本地運行DApp或相應的測試腳本來確保新的RPC URL可以正常工作，可以使用如`web3.eth.net.isListening()`或`ethers.provider.pollingInterval`等方法來檢查連接是否成功
4. 部署更新：如測試通過，可以將變更部署至生產環境

{% tabs %}
{% tab title="JavaScript" %}

```javascript
// 引入Web3
const Web3 = require('web3');

// 創建web3實例並連接到RPC URL
const web3 = new Web3('https://bsc.blockrazor.xyz'); // 可在此处将通用RPC URL替换为项目RPC URL

// 檢查連接
web3.eth.net.isListening()
  .then((listening) => {
    console.log('Web3 connected: ', listening);
  })
  .catch((err) => {
    console.error('Web3 connection error: ', err);
  });
```

{% endtab %}
{% endtabs %}

#### 3. 查詢交易

1. 登錄[blockrazor.io](https://blockrazor.io)
2. 在RPC模塊下點擊【返利】查看返利情況，點擊【交易】查看項目交易情況

## 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/bsc/ji-cheng-rpc.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.
