Ethereum Development

Core Philosophy

General Principles

• 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

Solidity Best Practices

Code Standards

• 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

Security Patterns

• 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

OpenZeppelin Integration

• 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

Optimization

• 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

Testing & Analysis

• 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

Development Workflow

• Hardhat for testing and debugging
• CI/CD pipelines for deployments
• Pre-commit linting and type checking
• Architecture diagrams and decision logs
