🔍 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.
