# 借贷配方

> 通过 LI.FI Composer 存入 Aave V3、HyperLend、Seamless、Maple 和 USDai 借贷协议的复制粘贴配方。

通过 Composer 存入支持的借贷协议的复制粘贴配方。

<Note>
  所有配方都使用 `GET /quote` 端点。相同的 `toToken` 地址适用于 `POST /advanced/routes` 和 LI.FI SDK。完整集成指南请参见 [API 集成](/composer/guides/api-integration) 或 [SDK 集成](/composer/guides/sdk-integration)。

### 跨链：Ethereum 上的 ETH → Arbitrum 上的 Aave V3

<CodeGroup>
  ```bash curl theme={"system"}
  curl -X GET 'https://li.quest/v1/quote?fromChain=1&toChain=42161&fromToken=0x0000000000000000000000000000000000000000&toToken=AAAVE_AUSDC_TOKEN_ADDRESS_ON_ARBITRUM&fromAddress=0xYOUR_WALLET_ADDRESS&toAddress=0xYOUR_WALLET_ADDRESS&fromAmount=100000000000000000'
  ```

  ```ts TypeScript theme={"system"}
  const quote = await axios.get('https://li.quest/v1/quote', {
    params: {
      fromChain: 1,                                                 // Ethereum
      toChain: 42161,                                                // Arbitrum
      fromToken: '0x0000000000000000000000000000000000000000',       // ETH (原生)
      toToken: 'AAAVE_AUSDC_TOKEN_ADDRESS_ON_ARBITRUM',             // Arbitrum 上的 Aave aUSDC
      fromAddress: '0xYOUR_WALLET_ADDRESS',
      toAddress: '0xYOUR_WALLET_ADDRESS',
      fromAmount: '100000000000000000',                             // 0.1 ETH
    },
  });
  ```
</CodeGroup>

<Tip>
  将 `AAAVE_AUSDC_TOKEN_ADDRESS_ON_BASE` 替换为您目标链上 Aave V3 市场的特定 aToken 地址。您可以在 [Aave 文档](https://docs.aave.com/developers/deployed-contracts) 上找到 aToken 地址。

    },
  });
  ```

## 通用模式

所有借贷配方都遵循相同的模式：

```
GET /quote
  fromChain  = 源链 ID
  toChain    = 目标链 ID（相同或不同）
  fromToken  = 您起始的代币
  toToken    = 借贷协议代币地址（这会触发 Composer）
  fromAmount = 最小单位的金额
  fromAddress = 您的钱包
  toAddress   = 您的钱包（接收借贷代币）
```

**唯一的 Composer 特定细节**是 `toToken` 必须是支持的借贷协议的代币地址（例如 Aave 的 aToken）。
