solidity-security

Comprehensive smart contract security patterns, vulnerability prevention, and secure Solidity development practices.

- Covers critical vulnerabilities including reentrancy, integer overflow/underflow, access control failures, and front-running with vulnerable code examples and secure patterns

- Teaches Checks-Effects-Interactions pattern, pull-over-push payment design, input validation, and emergency stop mechanisms for production-ready contracts

- Includes gas optimization techniques such as storage packing, calldata usage, and event-based data storage

- Provides security checklist, Hardhat testing examples for vulnerability detection, and audit preparation guidelines with proper documentation standards
