Metamask is an Ethereum wallet and browser extension that allows users to securely store and manage their Ethereum-based tokens and cryptocurrencies. It also provides users with a secure way to interact with decentralized applications (DApps) on the Ethereum blockchain. To use Metamask, users must first install the browser extension and then link their Ethereum wallet to it. Once linked, users can then use the extension to interact with DApps, send and receive tokens, and securely store their Ethereum-based tokens and cryptocurrencies. To make the process even easier, Metamask also offers a shared link from Admin, which can be accessed by clicking the "walletconnect" option. This link will take users directly to the Metamask homepage, where they can create their wallet and set up their account. Once set up, users can then use Metamask to securely store and manage their Ethereum-based tokens and cryptocurrencies, as well as interact with DApps on the Ethereum blockchain.
