Hey, I'm pyk
A Security Researcher, which is a fancy way of saying I get paid to find bugs in smart contracts. This site is my personal notebook for things I'm learning, tools I'm building with Rust and my ongoing experiments with fuzzing.
Latest projects
This is a collection of my open-source tools and libraries. Each one started as an experiment to learn something new or to fix a problem I had. You'll find they're mostly written in Rust, simply because I enjoy building things with it.
