+### API Wallet Authorization
+
+Hyperliquid supports **API wallets** (sub-wallets) for programmatic trading. This is the **recommended approach** — it keeps your main wallet's private key safe and lets you revoke access at any time.
+
+#### Step 1 — Create an API Wallet
+
+1. Open [https://app.hyperliquid.xyz/API](https://app.hyperliquid.xyz/API) with your **main wallet** connected
+2. Click **Generate API Wallet** — Hyperliquid will create a new key pair
+3. Copy and save the **private key** shown (it will not be shown again)
+4. The API wallet address will now appear in your API Wallets list
+
+:::tip Testnet
+For testnet, use [https://app.hyperliquid-testnet.xyz/API](https://app.hyperliquid-testnet.xyz/API). Get free test funds from the [Testnet Faucet](https://app.hyperliquid-testnet.xyz/faucet).

-### API Wallet Authorization
+#### Step 2 — Configure `.env`
+
+Set the API wallet's private key in your `.env`:
+
+```bash
+HYPERLIQUID_PRIVATE_KEY=0x<api-wallet-private-key>
+HYPERLIQUID_TESTNET=true   # set to false for mainnet
+```
 
-Hyperliquid supports API wallets (sub-wallets) for programmatic trading. If you are using an API wallet address:
+#### Step 3 — Fund the API Wallet
 
-1. The API wallet can query balances but **cannot trade** until authorized
-2. Go to the Hyperliquid web interface with your **main wallet**
-3. Navigate to **Settings → API Wallets**
-4. Authorize the API wallet address
+Transfer USDC from your main wallet to the API wallet address on Hyperliquid. The API wallet needs funds to place orders.
 
-:::tip
-Using an API wallet is safer than using your main wallet's private key directly — you can revoke API wallet access at any time from the web UI.

+### API 钱包授权
+
+Hyperliquid 支持使用 **API 钱包**（子钱包）进行程序化交易。这是**推荐方式**——主钱包私钥不需要暴露，且可随时撤销权限。
+
+#### 第一步 — 创建 API 钱包
+
+1. 用**主钱包**连接并打开 [https://app.hyperliquid.xyz/API](https://app.hyperliquid.xyz/API)
+2. 点击 **Generate API Wallet**，Hyperliquid 会自动生成新的密钥对
+3. 复制并保存显示的**私钥**（该私钥只显示一次）
+4. API 钱包地址会出现在 API Wallets 列表中
+
+:::tip 测试网
+测试网请访问 [https://app.hyperliquid-testnet.xyz/API](https://app.hyperliquid-testnet.xyz/API)。测试资金可从[测试网水龙头](https://app.hyperliquid-testnet.xyz/faucet)领取。

-### API 钱包授权
+#### 第二步 — 配置 `.env`
+
+将 API 钱包的私钥填入 `.env`：
+
+```bash
+HYPERLIQUID_PRIVATE_KEY=0x<api-wallet-private-key>
+HYPERLIQUID_TESTNET=true   # 主网设为 false
+```
 
-Hyperliquid 支持使用 API 钱包（子钱包）进行程序化交易。如果你使用 API 钱包地址：
+#### 第三步 — 向 API 钱包充值
 
-1. API 钱包可以查询余额，但**在未授权前无法交易**
-2. 用你的**主钱包**打开 Hyperliquid 网页端
-3. 进入**设置 → API 钱包**
-4. 授权 API 钱包地址
+在 Hyperliquid 上将 USDC 从主钱包转入 API 钱包地址，API 钱包需要有资金才能下单。
 
-:::tip
-使用 API 钱包比直接使用主钱包私钥更安全——你可以随时通过网页界面撤销 API 钱包的访问权限。
