Cookbook
A search engine for EVM smart contracts and open source.

What is Cookbook?
The Cookbook is a community-sourced collection of smart contracts for developers to download code and use to their liking. Users can browse a growing number of smart contracts by searching use cases or blockchains. Developers can offer new smart contracts, contribute to quality-checking existing contracts and add support for more chains through a discord community. Cookbook also supports Metis, Cronos, Ethereum Classic, Aurora, Fantom, Fuse, Milkomeda, Boba, Moonbeam, and Moonriver.
