🚀 What is MetaMask Wallet Extension?

MetaMask is a browser extension that turns your Chrome, Firefox, Brave, or Edge browser into a powerful crypto wallet. Think of it as your digital keychain for blockchain-based assets:

  • Digital asset storage: Keep ETH, ERC-20, ERC-721 (NFTs), plus tokens from custom networks.
  • DApp access: Use decentralized apps like Uniswap, OpenSea, Aave, Chainlink, and more.
  • Seamless transactions: Send, receive, and swap tokens with ease.
  • Network flexibility: Connect to Ethereum Mainnet, testnets (Goerli, Sepolia), Layer-2s (Arbitrum, Optimism), and even custom RPC networks.

It's the perfect bridge between traditional browsing and the decentralized future. 🏗️
