🎯 重构优势

1. 模块清晰：三大功能模块分离，易于维护
2. 扩展性强：新增功能只需在对应模块添加
3. 并发支持：Monad高并发优化，支持万级请求
4. 代码复用：通用功能抽离为工具函数
5. 易于测试：每个模块可独立测试
6. 团队协作：不同开发者可负责不同模块

📈 下一步开发建议

1. 优先实现核心功能：

   • NFT铸造（Monad集成）
   • Redis激活码管理
   • 基本身份验证

2. 逐步添加高级功能：

   • DOT质押系统
   • 二手书交易市场
   • Matrix集成

3. 优化和监控：

   • 添加Prometheus监控
   • 实现链路追踪
   • 性能测试和优化

这个重构方案为你的金库协议提供了良好的架构基础，未来可以轻松扩展新功能而不会让代码变得混乱。
