Installation | 安裝

# Clone the repository | 克隆儲存庫
git clone https://github.com/your-username/scallop-deepbook-kit.git
cd scallop-deepbook-kit

# Install dependencies | 安裝依賴
pnpm install

# Setup environment variables | 設定環境變數
cp .env.example .env
# Edit .env and add your PRIVATE_KEY | 編輯 .env 並新增您的 PRIVATE_KEY

Quick Start | 快速開始

1. Configure Environment | 配置環境

Create a .env file in the project root: 在專案根目錄建立 .env 檔案：

# Required: Your wallet private key (hex format, without 0x prefix)
# 必需：您的錢包私鑰（hex 格式，不含 0x 前綴）
PRIVATE_KEY=your_private_key_here

# Optional: These will be auto-generated and saved
# 可選：這些會自動產生並儲存
# SUPPLIER_CAP_ID=
# SUI_REFERRAL_ID=
# DBUSDC_REFERRAL_ID=

2. Run the Demo | 執行示範

# Run the complete toolkit demo | 執行完整的 toolkit 示範
pnpm example:toolkit

The demo will: 示範程式將會：

• Create or load Supplier Cap | 創建或載入 Supplier Cap

3. Use the Toolkit in Your Code | 在程式碼中使用 Toolkit

import { DeepBookMarginToolkit } from './toolkit';

// Initialize the toolkit | 初始化 toolkit
const toolkit = new DeepBookMarginToolkit({
  network: 'testnet',
  privateKey: process.env.PRIVATE_KEY!,
  supplierCapId: process.env.SUPPLIER_CAP_ID, // Optional | 可選
});

// Initialize (creates Supplier Cap if needed) | 初始化（需要時創建 Supplier Cap）
await toolkit.initialize();

// Create a referral | 創建 referral
const referralId = await toolkit.createSupplyReferral('SUI');

// Supply to margin pool | 供應到 margin pool
await toolkit.supplyToMarginPool('SUI', 0.1, referralId);

// Get balance | 查詢餘額
const balance = await toolkit.getBalance('SUI');
console.log(`Supply amount: ${balance.userSupplyAmount}`);
console.log(`Wallet balance: ${balance.walletBalance}`);

// Withdraw from margin pool | 從 margin pool 提取
