Description of Web3 Penetration Testing and Smart Contract Auditing
This comprehensive training guides you step by step through Web3 penetration testing and smart contract auditing. You'll start by exploring blockchain fundamentals and understanding how decentralized applications operate. Then, you'll learn to set up your lab environment with tools like Remix IDE, Metamask, and Hardhat, gaining hands-on experience auditing and exploiting smart contracts.
Through real-world examples such as the Parity Wallet hack, youβll uncover critical vulnerabilities, develop proof of concept exploits, and learn how to write professional audit reports. The course also dives into bug bounty programs, empowering you to identify security risks, perform manual reviews, and secure decentralized ecosystems against malicious actors.
- Analyze smart contracts for common vulnerabilities and smart contract security audit
- Deploy and test contracts in controlled environments and web penetration testing
- Perform exploitation using Ethernaut challengesΒ
- Document findings in clear, actionable reportsΒ
- Understand the audit process and mitigate potential risks in network security
- Build expertise in blockchain security and Web3 penetration testing
- Learn the basics of Solidity, including data types, functions, modifiers, constructors, and mappings.
- Solve hands-on security labs with real-world Web3 exploits, including Token, Vault, Fallout, and Force challenges.
By completing this course, youβll gain the skills needed to uncover internal vulnerabilities, identify common vulnerabilities in smart contracts deployed across decentralized applications, and protect against external threat actors. Youβll be equipped to improve security posture and respond to security incidents.

Julian A.
The first section explains the basics of smart contract development in solidity. But for me the second section was more useful, the part that explains the important exploits.

Piyush J.
This is one of the best courses I've come across for learning the fundamentals of blockchain. The course is designed by the best teacher/mentor of mine. Learning blockchain and how to test for its vulnerabilities with such great practical resources are limited on the internet. Feeling very happy that I purchase this course and learn from it.

Maur D.
The course is great for starters. I think it should be upgraded with all challenges from the Ethernaut. It really helped me understand decentralized applications and the comprehensive process of identifying weaknesses and improving my overall security posture.
