A Web3 browser is a specialized web browser designed to interact with decentralized applications (dApps) and blockchain networks like Ethereum. Unlike traditional browsers, Web3 browsers integrate cryptocurrency wallets, support smart contract interactions, and prioritize privacy and security. Popular examples include MetaMask, Brave, and Trust Wallet.
