Smart Contract Security & Ethical Hacking Course – Become a Professional Web3 Defender
Introduction
This course teaches you the ethical and professional techniques required to secure smart contracts against real-world threats. You’ll learn how vulnerabilities arise, how to identify and verify them in controlled environments, and how to apply secure design principles to remediate issues effectively. The focus is on defense, auditing excellence, and responsible disclosure—never malicious exploitation.
Course Overview
Beginning with blockchain fundamentals and core Solidity concepts, you’ll progress into deep security analysis of smart contracts. You’ll study the most common vulnerability classes, practice secure coding patterns, and learn how to validate contract behavior using local testnets, automated analysis, and formal review processes.
Throughout the course, you’ll build a complete auditor’s workflow—static analysis, fuzzing, invariants, testing frameworks, documentation, and industry-standard disclosure procedures—equipping you with the skills required for real audit work.
