cairo contract rules

When reviewing or writing code, apply these guidelines:

• Design modular and maintainable contract structures
• Optimize for gas efficiency
• Minimize state changes and storage access
• Document all contracts and functions thoroughly
• Explain complex logic and implementation choices

hardhat development workflow

When reviewing or writing code, apply these guidelines:

• 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.

solidity best practices

When reviewing or writing code, apply these guidelines:

• 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 0.8.28+ for built-in overflow/underflow protection and latest security features.
• 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 f

Memory Protocol (MANDATORY)

Before starting:

cat .claude/context/memory/learnings.md

After completing: Record any new patterns or exceptions discovered.

ASSUME INTERRUPTION: Your context may reset. If it's not in memory, it didn't happen.
