This is an important feature in MetaMask because it allows you to be in control of what you approve of. MetaMask manages this by allowing you to permit the DApp to retrieve your address to interact with it. One of the use cases for a tool like MetaMask is to allow its users to interact with decentralized applications, such as DeFi platforms, decentralized exchanges, NFT marketplaces, game applications on a blockchain, and more.

But in this case you are the holder of the keys, as opposed to the traditional system where the website holds your login information somewhere on a server under their control. In short, we can compare the public and private keys to login information for a website, where the public key is your username, and the private key is the password. If you lose your private key, you lose access to the account and the funds in it. Note that whoever controls the private key controls the account funds. When an account receives a transaction, it uses the private key to decode it and access the funds, and because the private key is unique to that account, other accounts cannot access it. The private key is also an alphanumeric string of data, but MetaMask associates it to a single account in a wallet. In Ethereum-based environments, the address begins with 0x.įor example: 0x06A85356DCb5b307096726FB86A78c59D38e08ee The public key, also known as an address in the Web3 environment, is an alphanumeric character string used to encrypt the transactions that the account makes and it is available to anyone to see. An example is a hardware wallet that separates the wallet from the Web3 environment and keeps it safer. These keys are essential to guarantee that the transactions executed are legitimately done by the account’s owner, and the user can manage the keys in a variety of ways. When you create a new account on MetaMask, it generates a new pair consisting of a private and a public key. You can consider it a cryptographic account manager that uses cryptography to keep the keys of your account secure.
Most people know MetaMask as a crypto wallet, but it is much more than just that. It was created to help users have a secure, reliable, and easy connection to Ethereum-based blockchains.
MetaMask is available as a browser extension and as a mobile app on iOS and Android. MetaMask is a tool that allows you to store tokens, interact with decentralized applications (DApps), and experience Web3.
