Smart Contract Vulnerabilities In Solidity

This course aims to provide a comprehensive introduction to the key concepts and techniques of smart contract security. The content covers reentrancy attacks, access control, flash loan attacks, DOS attacks, transaction frontrunning, replay attacks, oracle issues, common attacks on ERC20, common attacks on NFTs, and other smart contract security issues. Through this series of courses, students will gain an in-depth understanding of various security vulnerabilities and their prevention methods, laying a solid foundation for future smart contract development and security audits.
