Andreas Bigger
Engineer. Investor. Writer.
About
I build the Base chain in Rust at Base. Outside of that, I'm a deep value investor — I write about fallen angels, temporarily disliked companies, and businesses the market has written off. I also angel invest; reach out on X.
You can find my writing at substack and my code at github.com/refcell.

All postsA routine version bump. A database that wouldn't open. And a bug that had been hiding in plain sight for years.
Papers
EVMBench: Benchmarking AI Agents on EVM Smart Contract Security
An open evaluation framework that tests AI agents across detecting, patching, and exploiting vulnerabilities in EVM smart contracts. Uses real vulnerabilities from public code audits and custom tasks from unreleased contracts, with each task containerized for realistic testing environments.
