Biography

Hey! Zigtur here!

I'm a Lead Security Researcher at Spearbit & Cantina. I'm also a Rust instructor at Rareskills.

Rust, Go, Solidity, even Java: I find bugs in any language!

Ethereum, Solana, Cosmos, even Bitcoin: I find bugs in any stack!

More of my work can be found on Github at zigtur/audits.
