Research & Publications
Petrichor is an advanced writing app that fuels a deeper understanding of your interests. It’s designed for anyone who loves diving deep into research and making unexpected connections between ideas. By merging an intuitive editor, automatic semantic linking, and AI-powered assistance, Petrichor helps you stay organized and uncover new insights as you write.
In this experimental paper, we will dive into EVM bytecode and examine distinct patterns and markers left by different major EVM compilers. We'll also explore the potential for using these patterns to identify the compiler used to generate a given contract's bytecode.
The heimdall-rs 0.8.0 release is our largest update to date with 34 merged PRs, hundreds of closed issues, countless hours of work, and six new contributors! Due to the sheer size of this release, we've decided to make a blog post to highlight the most significant changes.

Talks & Presentations
On Scraping Bits, I talk about building my EVM toolkit and bytecode analyzer, Heimdall, and how it can be used to reverse engineer smart contracts.
At OpenSense, I present an introduction to the EVM and dive into the internals of smart contracts.
At Paradigm's Rust x Ethereum Day in San Francisco, I talk briefly about Heimdall, a bytecode analysis toolkit for the EVM.
