MetaMask Extension: The Self-Custodial Wallet for Your Browser

MetaMask is a popular cryptocurrency wallet and browser extension that allows users to interact with the Ethereum blockchain and decentralized applications (dapps). It is a non-custodial wallet, meaning that users have full control over their private keys and funds. MetaMask is easy to use and supports a wide range of features, making it a popular choice for both beginners and experienced crypto users alike.

What is MetaMask?

MetaMask is a browser extension that allows users to interact with the Ethereum blockchain. It functions as a cryptocurrency wallet, allowing users to send and receive ETH and ERC-20 tokens. MetaMask also allows users to connect to and interact with decentralized applications (dapps).

Dapps are applications that are built on the Ethereum blockchain. They allow users to perform a variety of tasks, such as trading tokens, playing games, and participating in decentralized finance (DeFi) protocols. MetaMask makes it easy to connect to and interact with dapps without having to leave your browser.

How does MetaMask work?

MetaMask works by creating a local copy of the Ethereum blockchain on your computer. This allows you to interact with the blockchain without having to rely on a third-party service. MetaMask also stores your private keys locally, giving you full control over your funds.

To use MetaMask, you first need to create an account. Once you have created an account, you can import an existing Ethereum wallet or create a new one. MetaMask will then generate a 12-word secret recovery phrase. This phrase is important because it allows you to recover your wallet if you lose your password or private keys.

Once you have created and funded your MetaMask wallet, you can start interacting with dapps. To do this, simply navigate to the dapp website in your browser and click the "Connect to Wallet" button. You will then be prompted to select your MetaMask wallet. Once you have selected your wallet, you will be able to interact with the dapp as if you were using a traditional wallet.
