Introducing MetaMask Snapps: A New Way to Extend the Functionality of MetaMask πŸš€

With its code open Sourced and its SDKs available now it’s becoming an extensible platform for permissionless innovation with the introduction of MetaMask Snapps.

Snapps, or β€œsnaps,” are plugins that allow developers to extend the functionality of MetaMask, bringing new features and APIs to the wallet. πŸ”Œ

With Snapps, developers can go beyond Ethereum and integrate any blockchain protocol, scaling solution, or API into MetaMask. Snapps can also be used to enable authentication, privacy, and consent in ways that keep users in control. Additionally, developers can use Snapps to empower users with more ways to protect their data and employ anti-phishing solutions. πŸ”’

Snapps execute in a sandboxed environment based on Hardened JavaScript by Agoric and use a permissions model for protecting user data and respecting user consent. To try Snapps, developers can install MetaMask Flask, a canary distribution that provides access to upcoming features. 🐦

A snap is a JavaScript program that runs in an isolated environment and customizes the wallet experience. Snaps have access to a limited set of capabilities determined by the permissions granted by the user during installation. With a snap, developers can add new API methods to MetaMask, add support for different blockchain protocols, or modify existing functionalities using the Snaps JSON-RPC API. πŸ’»

Some of the features that can be added using Snapps include dialogs, notifications, encrypted storage, non-EVM chain support, transaction insights, cron jobs, custom UIs, and network access. πŸ””
