About

Kakarot is an (zk)-Ethereum Virtual Machine implementation written in Cairo. Kakarot is Ethereum compatible, i.e. all existing smart contracts, developer tools and wallets work out-of-the-box on Kakarot. It's been open source from day one. Soon available on Starknet L2 and Appchains.

🚧 It is a work in progress, and it is not ready for production.
