About me

Hello, I'm Klaus. I am a highly skilled security researcher, ranked 11th in code4rena in 2024.
I work primarily with Solidity, and I can also handle Rust-based contracts or Cairo. I'm specialized in DeFi, bridges, and multi-chain protocols.

If you want an audit or security consulting, feel free to contact me on X(@klaus_dev) or Discord(@klaus_).
