Core Monorepo

This monorepo is a collection of packages used across multiple MetaMask clients (e.g. metamask-extension, metamask-mobile).

Contributing

See the Contributor Guide for help on:

• Setting up your development environment
• Working with the monorepo
• Testing changes in clients
• Issuing new releases
• Creating a new package

Installation/Usage
