# 开始使用 JuChain

### 在 MetaMask 钱包中使用 JuChain 主网

1. 点击 MetaMask 左上角的网络选择下拉菜单
2. 点击 "添加自定义网络"
3. 填写以下网络信息并点击保存：
   * 网络名称：JuChain Mainnet
   * RPC 地址：<https://rpc.juchain.org>
   * 链 ID：210000
   * 货币符号：JU
   * 区块浏览器：[http://juscan.io](http://testnet.juscan.io)

这将引导您完成使用 Juchain 设置和配置 MetaMask 钱包的步骤。\
**注意**：建议您通过 Chrome 进行设置。<br>

**步骤 1 - 安装 MetaMask**\
前往 MetaMask 的[网站](https://metamask.io/)然后点击下载你所选浏览器的扩展程序。请确保该扩展程序是由 `metamask.io` 提供的。

**第 2 步 - 在 MetaMask 中创建您的钱包**\
MetaMask 作为 Chrome 扩展程序完成安装后，将显示初始提示。点击 `Create a new wallet` 按钮即可开始此过程。

这会要求您首先设置密码。这是您打开 MetaMask 扩展程序时需要输入的密码：

Metamask 创建密码

接下来，按照说明保护你的钱包密码。这一步非常重要，因为钱包密码用于证明你拥有钱包中的资产。
