Core Philosophy
核心理念
Cut the fluff. Code or detailed explanations only. Keep it casual and brief. Accuracy and depth matter.
摒弃冗余内容。仅保留代码或详细解释。风格随意简洁,准确性和深度至关重要。
General Principles
通用原则
- Prioritize logic over citations
- Embrace emerging technologies and unconventional solutions
- Flag speculative content clearly
- Omit ethical disclaimers unless critical for security
- Place sources at conclusion, not mid-text
- Provide complete code implementations without shortcuts
- 优先关注逻辑而非引用
- 接纳新兴技术和非常规解决方案
- 明确标记推测性内容
- 除非对安全至关重要,否则省略道德声明
- 将来源放在文末,而非文中
- 提供完整的代码实现,不偷工减料
Solidity Best Practices
Solidity最佳实践
Code Standards
代码规范
- Explicit visibility modifiers and NatSpec documentation
- Function modifiers for recurring checks and validation
- CamelCase for contracts, PascalCase for interfaces (prefix "I")
- Interface Segregation Principle for maintainability
- Proxy patterns for upgradeability
- 显式可见性修饰符和NatSpec文档
- 使用函数修饰符处理重复的检查和验证
- 合约使用驼峰命名法(CamelCase),接口使用帕斯卡命名法(PascalCase,前缀为“I”)
- 遵循接口隔离原则以提升可维护性
- 使用代理模式实现可升级性
Security Patterns
安全模式
- Comprehensive event logging for state modifications
- Checks-Effects-Interactions pattern for reentrancy prevention
- Pull-over-push payment mechanisms
- Rate limiting on sensitive operations
- ReentrancyGuard for additional protection
- Custom errors instead of revert strings
- 对状态修改进行全面的事件日志记录
- 使用Checks-Effects-Interactions模式防止重入攻击
- 采用拉取式而非推送式的支付机制
- 对敏感操作进行速率限制
- 使用ReentrancyGuard提供额外保护
- 使用自定义错误替代回退字符串
OpenZeppelin Integration
OpenZeppelin集成
- AccessControl for granular permissions
- SafeERC20 for token interactions
- Pausable for circuit breakers
- ERC20Snapshot, ERC20Permit, ERC20Votes for specialized tokens
- TimelockController for sensitive operations
- Address library for safe external calls
- 使用AccessControl实现细粒度权限控制
- 使用SafeERC20处理代币交互
- 使用Pausable实现断路器功能
- 为特殊代币使用ERC20Snapshot、ERC20Permit、ERC20Votes
- 使用TimelockController处理敏感操作
- 使用Address库进行安全的外部调用
Optimization
优化建议
- Solidity 0.8.0+ for built-in overflow/underflow protection
- Gas-efficient storage packing
- Assembly for performance-critical sections (with documentation)
- Immutable variables for compile-time constants
- Libraries for reducing contract size
- 使用Solidity 0.8.0+版本以获得内置的溢出/下溢保护
- 采用节省Gas的存储打包方式
- 对性能关键部分使用汇编(需附带文档)
- 使用不可变变量存储编译时常量
- 使用库来减小合约大小
Testing & Analysis
测试与分析
- Unit, integration, and end-to-end test coverage
- Property-based testing for edge cases
- Slither and Mythril static analysis
- High coverage on critical paths
- Security audits and bug bounties
- 单元测试、集成测试和端到端测试全覆盖
- 使用基于属性的测试覆盖边缘场景
- 使用Slither和Mythril进行静态分析
- 确保关键路径的高测试覆盖率
- 进行安全审计和漏洞悬赏
Development Workflow
开发工作流
- Hardhat for testing and debugging
- CI/CD pipelines for deployments
- Pre-commit linting and type checking
- Architecture diagrams and decision logs
- 使用Hardhat进行测试和调试
- 使用CI/CD流水线进行部署
- 提交前进行代码检查和类型校验
- 绘制架构图并记录决策日志
