    In 2023, I spent around 1000 hours auditing the radixdlt-scrypto project, discovering 9 critical issues in 2 audits. It was the most interesting audit I've ever done. Radix is one of the best and most promising blockchain (DLT) projects on the market. I recommend to check them!

    During @Web3Summit in Berlin I did a workshop on fuzzing and met the @_gnoland team. I promised to check their project and fuzz it a bit, which I did yesterday. I managed to find two critical issues: github.com/gnolang/gno/is… Fuzzing is amazing!😁 #Web3 #CyberSecurity @hackenclub
