MetaMask allows users to manage, store, and interact with Ethereum-based cryptocurrencies and applications directly from their web browser. It provides users with a secure way to create and manage Ethereum wallets, send and receive ETH and other tokens on the network, making it easier for users to engage with DeFi platforms, NFT marketplaces, and other web3 services. Users can install the MetaMask extension in their browser, set up a wallet, and then use it to interact with smart contracts and applications. Now that same frictionless setup experience is available for anyone who wishes to explore the Cosmos.
With that much power, MetaMask needed to ensure Snaps didn’t expose users to new vulnerabilities.
