🔍 Day 46 of #100DaysOfBlockchain: Fuzz Testing Unveils Hidden Vulnerabilities

Today, I dove deep into fuzz testing, invariants, and handler contracts in my smart contract security course. Focusing on stateful and stateless fuzz testing was both challenging and fascinating.

🛠 What I Learned: I discovered a sneaky issue—a malicious ERC20 token that steals 10% of transfers after the 10th transaction. It was a real eye-opener, showing just how crucial fuzz testing is for catching vulnerabilities that regular tests might miss.

🚀 Why It Matters: While I’m not aiming to become a security researcher, this course is helping me write more secure smart contracts. Today’s lesson highlighted the importance of making sure contracts can handle the unexpected.

🌱 Takeaways: Fuzz testing isn’t just about finding bugs; it’s about building resilient systems. Each challenge I tackle moves me closer to becoming a top-tier smart contract developer.

Great job on completing your first smart contract audit! Ensuring security and reliability in code is crucial in the blockchain space. Looking forward to seeing your progress as you delve deeper into smart contract security. Keep up the good work! 🚀🔐
