Hi, my name is Zak Cole.

I am a blockchain protocol engineer, DeFi enthusiast, and angel investor.

You might know me through my Ethereum protocol research or general Internet hijinks.

Currently, I am the co-founder and CTO of Slingshot, a decentralized exchange.

I co-founded Code4rena, a smart contract auditing DAO, and contribute to Canto, a DeFi specific blockchain ecosystem.

Previously, I founded a company called Whiteblock, which specialized in blockchain protocol testing, research, and development.

I also worked at Google and founded the Testing Working Group at the Ethereum Enterprise Alliance.

I serve as advisor to several blockchain related companies, like Cryptex, DeFi Pulse and the Syscoin Foundation.
