Description

The world's most trusted crypto wallet MetaMask Flask is a distribution channel of the MetaMask Extension for developers, which gives them access to additional unstable APIs. 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 these lessons into the main MetaMask distribution.
