Introduction to MetaMask
MetaMask is a widely used Ethereum wallet and browser extension that allows users to manage their crypto assets securely. It acts as a bridge between your browser and the Ethereum blockchain, enabling interaction with decentralized applications (dApps) seamlessly.
With MetaMask, you can store ETH and ERC-20 tokens, participate in DeFi, and interact with NFT platforms without the need for a full Ethereum node. Learn more about Ethereum wallets in our Features section.
