Today’s guest is Vex, a software engineer, smart contract developer, and major contributor to Huff - a low level assembly language for the Ethereum Virtual machine.

Vex knows a ton about the EVM at the low level, and we go deep into why Huff is a great language to learn for building incredibly gas efficient contracts. Huff is also being used more and more as an educational tool, as it allows you to build programs that are, as Josh says, equivalent to ‘bare metal ethereum.’

If you’re interested in low level smart contract languages, and developing a deeper understanding of how the EVM works, you’ll love this episode.
