Core Principles
核心原则
- Cut the fluff. Code or detailed explanations only
- Maintain brevity while prioritizing accuracy and depth
- Answer first, explain later when needed
- 摒弃无用内容,仅提供代码或详细解释
- 保持简洁,同时优先保证准确性与深度
- 先给出答案,必要时再做后续解释
Code Structure & Security
代码结构与安全
- Use explicit visibility modifiers and NatSpec documentation
- Apply function modifiers to reduce redundancy
- Follow naming conventions:
- CamelCase for contracts
- PascalCase for interfaces (prefix with "I")
- Implement Interface Segregation Principle
- Use proxy patterns for upgradeable contracts
- Emit comprehensive events for state changes
- Follow Checks-Effects-Interactions pattern against reentrancy
- 使用显式可见性修饰符和NatSpec文档
- 应用函数修饰符减少冗余
- 遵循命名规范:
- 合约使用CamelCase命名
- 接口使用PascalCase命名(以"I"为前缀)
- 实现接口隔离原则
- 可升级合约使用代理模式
- 针对状态变更触发完整的事件
- 遵循检查-生效-交互模式防范重入攻击
Security Best Practices
安全最佳实践
- Use OpenZeppelin's AccessControl for permissions
- Require Solidity 0.8.0+ for overflow/underflow protection
- Use Pausable pattern for circuit breakers
- Implement ReentrancyGuard for additional protection
- Use SafeERC20 for token interactions
- Employ pull-over-push payment patterns
- Implement timelocks and multisig controls for sensitive operations
- 权限管理使用OpenZeppelin的AccessControl
- 要求使用Solidity 0.8.0及以上版本以获得溢出/下溢保护
- 断路器功能使用Pausable模式
- 实现ReentrancyGuard提供额外防护
- 代币交互使用SafeERC20
- 支付模式采用拉取优先于推送的策略
- 敏感操作实现时间锁和多签控制
Gas Optimization
Gas优化
- Optimize gas consumption (deployment and runtime)
- Use immutable variables for constructor-set values
- Use custom errors instead of revert strings
- Pack storage variables efficiently
- Use appropriate data types
- 优化Gas消耗(部署阶段与运行时)
- 构造函数赋值的变量使用immutable修饰
- 使用自定义错误而非revert字符串
- 高效打包存储变量
- 选用合适的数据类型
Tools & Analysis
工具与分析
- Integrate Slither and Mythril for static analysis
- Leverage Hardhat's testing and development environment
- Implement robust CI/CD pipelines
- Use pre-commit linting tools
- 集成Slither和Mythril做静态分析
- 使用Hardhat测试与开发环境
- 实现健壮的CI/CD流水线
- 使用pre-commit linting工具
Advanced Patterns
高级模式
- Chainlink VRF for randomness
- Strategic assembly use with extensive documentation
- State machine patterns for complex logic
- ERC20Snapshot, ERC20Permit, and ERC20Votes for specialized tokens
- 随机数生成使用Chainlink VRF
- 有策略地使用assembly并附带详尽文档
- 复杂逻辑使用状态机模式
- 特殊代币实现使用ERC20Snapshot、ERC20Permit和ERC20Votes
Testing & Quality
测试与质量
- Comprehensive unit, integration, and end-to-end testing
- Property-based testing approaches
- High coverage targets
- Regular security audits
- 完整的单元测试、集成测试与端到端测试
- 基于属性的测试方法
- 高覆盖率目标
- 定期安全审计
