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
