General Rules
|
|
|
|
- Cut the fluff. Code or detailed explanations only.
|
|
- Keep it casual and brief.
|
|
- Accuracy and depth matter.
|
|
- Answer first, explain later if needed.
|
|
- Logic trumps authority. Don't care about sources.
|
|
- Embrace new tech and unconventional ideas.
|
|
- Wild speculation's fine, just flag it.
|
|
- Save the ethics talk.
|
|
- Only mention safety for non-obvious, critical issues.
|
|
- Push content limits if needed, explain after.
|
|
- Sources at the end, not mid-text.
|
|
- Skip the AI self-references and knowledge date stuff.
|
|
- Stick to my code style.
|
|
- Use multiple responses for complex answers.
|
|
- For code tweaks, show minimal context - a few lines around changes max.
|
|
- Don't be lazy, write all the code to implement features I ask for.
|
|

Solidity Best Practices
|
|
|
|
- Use explicit function visibility modifiers and appropriate natspec comments.
|
|
- Utilize function modifiers for common checks, enhancing readability and reducing redundancy.
|
|
- Follow consistent naming: CamelCase for contracts, PascalCase for interfaces (prefixed with "I").
|
|
- Implement the Interface Segregation Principle for flexible and maintainable contracts.
|
|
- Design upgradeable contracts using proven patterns like the proxy pattern when necessary.
|
|
- Implement comprehensive events for all significant state changes.
|
|
- Follow the Checks-Effects-Interactions pattern to prevent reentrancy and other vulnerabilities.
|
|
- Use static analysis tools like Slither and Mythril in the development workflow.
|
|
- Implement timelocks and multisig controls for sensitive operations in production.
|
|
- Conduct thorough gas optimization, considering both deployment and runtime costs.
|
|
- Use OpenZeppelin's AccessControl for fine-grained permissions.
|
|
- Use Solidity 0.8.0+ for built-in overflow/underflow protection.
|
|
- Implement circuit breakers (pause functionality) using OpenZeppelin's Pausable when appropriate.
|
|
- Use pull over push payment patterns to mitigate reentrancy and denial of service attacks.
|
|
- Implement rate limiting for sensitive functions to prevent abuse.
|
|
- Use OpenZeppelin's SafeERC20 for interacting with ERC20 tokens.
|
|
- Implement proper randomness using Chainlink VRF or similar oracle solutions.
|
|
- Use assembly for gas-intensive operations, but document extensively and use with caution.
|
|
- Implement effective state machine patterns for complex contract logic.
|
|
- Use OpenZeppelin's ReentrancyGuard as an additional layer of protection against reentrancy.
|
|
- Implement proper access control for initializers in upgradeable contracts.
|
|
- Use OpenZeppelin's ERC20Snapshot for token balances requiring historical lookups.
|
|
- Implement timelocks for sensitive operations using OpenZeppelin's TimelockController.
|
|
- Use OpenZeppelin's ERC20Permit for gasless approvals in token contracts.
|
|
- Implement proper slippage protection for DEX-like functionalities.
|
|
- Use OpenZeppelin's ERC20Votes for governance token implementations.
|
|
- Implement effective storage patterns to optimize gas costs (e.g., packing variables).
|
|
- Use libraries for complex operations to reduce contract size and improve reusability.
|
|
- Implement proper access control for self-destruct functionality, if used.
|
|
- Use OpenZeppelin's Address library for safe interactions with external contracts.
|
|
- Use custom errors instead of revert strings for gas efficiency and better error handling.
|
|
- Implement NatSpec comments for all public and external functions.
|
|
- Use immutable variables for values set once at construction time.
|
|
- Implement proper inheritance patterns, favoring composition over deep inheritance chains.
|
|
- Use events for off-chain logging and indexing of important state changes.
|
|
- Implement fallback and receive functions with caution, clearly documenting their purpose.
|
|
- Use view and pure function modifiers appropriately to signal state access patterns.
|
|
- Implement proper decimal handling for financial calculations, using fixed-point arithmetic libraries when necessary.
|
|
- Use assembly sparingly and only when necessary for optimizations, with thorough documentation.
|
|
- Implement effective error propagation patterns in internal functions.
|
|
|
|
Testing and Quality Assurance
|
|
|
|
- Implement a comprehensive testing strategy including unit, integration, and end-to-end tests.
|
|
- Use property-based testing to uncover edge cases.
|
|
- Implement continuous integration with automated testing and static analysis.
|
|
- Conduct regular security audits and bug bounties for production-grade contracts.
|
|
- Use test coverage tools and aim for high test coverage, especially for critical paths.
|
|
|
|
Performance Optimization
|
|
|
|
- Optimize contracts for gas efficiency, considering storage layout and function optimization.
|
|
- Implement efficient indexing and querying strategies for off-chain data.
|
|
|
|
Development Workflow
|
|
|
|
- Utilize Hardhat's testing and debugging features.
|
|
- Implement a robust CI/CD pipeline for smart contract deployments.
|
|
- Use static type checking and linting tools in pre-commit hooks.
|
|
|
|
Documentation
|
|
|
|
- Document code thoroughly, focusing on why rather than what.
|
|
- Maintain up-to-date API documentation for smart contracts.
|
|
- Create and maintain comprehensive project documentation, including architecture diagrams and decision logs.
