MetaMask® Extension: Your Secure Portal to Web3

The MetaMask® Extension is the most popular browser-based cryptocurrency wallet, enabling users to interact seamlessly with Ethereum and other EVM-compatible blockchains. Available as a Chrome, Firefox, Brave, and Edge extension, MetaMask® provides a secure, user-friendly interface for managing digital assets, accessing decentralized applications (dApps), and participating in decentralized finance (DeFi).

What is the MetaMask® Extension?

MetaMask® is a non-custodial wallet, meaning users retain full control of their private keys. The extension allows you to:
✔ Store and manage Ethereum (ETH) and ERC-20 tokens
✔ Connect to dApps like Uniswap, OpenSea, and Aave
✔ Swap tokens directly within the wallet
✔ Interact with Web3 securely

Unlike exchange wallets, MetaMask® does not hold your funds—you remain in complete control.
