"What a game-changer! I just completed Part 1 of Johnny's Smart Contract Hacking Course. Over 20 hours of video and hands-on coding exercises. As someone just starting into Solidity Security, I found the course to be a godsend. The hands-on approach is fantastic – detailed code walk-throughs and real-world testing with Hardhat. Highly recommend!"

"Bunch of new users today from the video – we got 42 users and counting! Usage was so good this week that our servers went down for a bit, which in my view is amazing. Thank you again for the fantastic work!"
