Kakarot is a zkEVM (zero-knowledge Ethereum Virtual Machine) implemented in Cairo, a language associated with the CairoVM. It enables the deployment of Ethereum smart contracts on Starknet, a layer 2 scaling solution for Ethereum, while providing provable transactions and blocks. Developers can utilize Kakarot to build and deploy EVM apps, maintaining compatibility with the Ethereum ecosystem and offering interoperability with native Starknet protocols.
