Before You Start ⚠️
Before you can build and test a Snap, you should have our experimental version of MetaMask installed. You will want to create a new browser profile or use a different browser than their regular MetaMask. Or disable "MetaMask proper" while MetaMask Flask is running.
This fork of MetaMask for developers (Flask) does everything a proper MetaMask wallet can do, with the addition of running Snaps.
From our webpage, you can link to the chrome extension for Flask.
*Flask only exists as a Chrome & Firefox extension. There is no fork or experimental version of MetaMask Mobile.
Start Here 🎯
To start building a Snap, follow this 5-minute tutorial teaching the basics tools, working with permissions, and adding an external API: Gas Fee Snap.

Hackathon Tips 🪄
We seek new and exciting use cases made possible only via the Snaps platform.
Beyond innovation, practicality, functionality, and proper usage of MetaMask Snaps, which are all very important, communication of your idea and its features and explaining what your project does that you can't do without MetaMask Snaps is just as important.

Truffle Suite Integration 🔗
If you are building with Truffle, this starter repo can help you start with TypeScript, a Template Snap, and a Truffle Box for developing and testing snaps that interact with smart contracts.
