Hi, I'm Veselin Vachkov, a smart contract security researcher with a solid Web2 foundation. What started as a suggestion from my cousin quickly turned into a deep passion for vulnerability research. Ratio changing bugs don't get past me, and I thrive on auditing non-standard, innovative protocol designs (something that you don't see every other day). I have been auditing since Dec 2024.
