MetaMask is a bridge that allows you to visit the distributed web of tomorrow in your browser today. It allows you to run Ethereum apps right in your browser without running a full Ethereum node.
MetaMask Mobile is Web3 in your pocket. It's your privacy-first, portable gateway to the decentralized world. Access, store, swap or manage digital assets, and browse the decentralized web with the world's most trusted, non-custodial Ethereum wallet.
The goal of Flask is to maximize developer control, so that we can learn the full extent of what developers want to do with MetaMask, and later incorporate those lessons into the main MetaMask distribution.
