Metamask Extension: the Crypto Wallet for Defi, Web3 Dapps and Nfts https://sites.google.com/uscoinlogin.com/metamaskextension/home/ MetaMask is an extension for accessing Ethereum enabled distributed applications, or "Dapps" in your browser! The extension injects the Ethereum web3 API into every website's javascript context, so that dapps can read from the blockchain. MetaMask Extension also lets the user create and manage their own identities (via private keys, local client wallet and hardware wallets like Trezor™)
