The MetaMask contains a one-of-a-kind Ethereum address for sending and receiving Ether and ERC-20 tokens. For wallet recovery, the 12-word seed phrase is critical. Private keys, which are kept secure, are used to sign transactions and provide access to cash. The balances of Ether (ETH) and ERC-20 tokens, as well as transaction histories, are presented. The browser extension allows users to customise settings, administer networks, and connect with decentralised applications. MetaMask Chrome Extension|Metamask Wallet | Metamask Login
