MetaMask Extension® | Your Gateway to Web3

MetaMask Extension is a powerful, user-friendly crypto wallet and gateway to blockchain-based applications, widely used to interact with the Ethereum blockchain and other EVM-compatible networks. Whether you're a beginner diving into the world of decentralized finance (DeFi) or a seasoned crypto trader, the MetaMask browser extension offers a secure and seamless experience in managing your digital assets directly from your browser.

What is MetaMask Extension?

The MetaMask Extension is a browser-based cryptocurrency wallet that allows users to store, send, and receive Ethereum and ERC-20 tokens. More than just a wallet, it serves as a bridge to decentralized apps (dApps), allowing users to access DeFi platforms, NFT marketplaces, blockchain games, and more.

With MetaMask, you retain full control of your private keys, and the wallet operates as a non-custodial solution—meaning you and only you own your crypto.
