This beginner-friendly course dives into the core security concepts behind Web3 and Ethereum smart contracts, empowering ethical hackers and curious developers with the skills to analyze, test, and secure decentralized applications.
Through guided labs and real-world vulnerabilities, you’ll explore how smart contracts are built, deployed, and attacked — using tools like Remix, Hardhat, and Slither. No prior blockchain experience required.
🏅 CERTIFICATION
Upon completion, you’ll earn the CWSE – Certified Web3 & Smart Contract Expert (Entry) certification — proving your ability to identify and remediate common flaws in Web3 applications.
Optional challenges and labs simulate actual audit conditions and exploit chains.
