I’m Asen, a blockchain security researcher focused on identifying vulnerabilities in smart contracts.
I actively participate in audit contests on platforms like Code4rena, Sherlock, CodeHawks, and Immunefi, where I’ve contributed to securing a wide range of DeFi protocols, bridges, and infrastructure projects.
Here's a quick overview of my track record in Web3 security research:
- 🧠 70+ accepted findings accross Code4rena, Sherlock, Codehawks, Immunefi
- 💰 $10,000+ earned in public contests
- 🥇 Top 5 and Top 10 placements in contests on Code4rena, Sherlock, and Immunefi
- 🧪 Audited protocols including bridges, launchpads, DEXes, and infrastructure
- ⚒️ Found bugs in different languages: Solidity, Cairo, Rust, Vyper,ChiaLisp
Below is a curated list of my public audit contest contributions.
Each entry reflects findings that were accepted and rewarded for identifying vulnerabilities across real-world protocols.
For a more detailed view of my audit history, see my profile here(couple of results missing due to not released reports by C4).
