 ## Overview
 
 MetaMask Snaps allow users to add features and functionality to their MetaMask wallet. Individual snaps are features created by third-party developers that MetaMask users can install directly into their wallet. MetaMask Snaps Open Beta is a first look at what's possible when extending the capabilities of the MetaMask wallet. Snaps run in a sandboxed environment and use a permissions model to protect your data and respect your consent. Snaps don’t have access to your MetaMask account data. When installing a Snap, you can always verify the permissions you are granting.

 ## Introduction
 
 The Astar Wallet Snap extends MetaMask's functionality, specifically for blockchains built with Substrate technology. The Astar Wallet Snap enables you to quickly generate a Substrate wallet with MetaMask for signing transactions and interacting with decentralized applications (dApps) that utilize the `@polkadot/extension-dapp package`. You can seamlessly interact with all dApps in the Astar ecosystem through MetaMask, thereby expanding MetaMask's utility beyond Ethereum and EVM-compatible networks.
