core

The MetaMask Core monorepo is an open-source collection of reusable JavaScript packages that power multiple MetaMask clients, including the extension and mobile app. It is designed for developers building on or contributing to the MetaMask ecosystem, providing foundational modules for wallet functionality, key management, and blockchain interactions. This project is interesting because it centralizes and standardizes core logic, enabling faster development, easier maintenance, and greater transparency across MetaMask’s expanding product suite.
