A wallet browser refers to a type of browser extension or application that allows users to access and manage their cryptocurrency wallets directly within their web browser. It enables users to view their digital asset balances, send and receive cryptocurrencies, and interact with decentralized applications (dApps) seamlessly without needing to switch between different platforms or applications. Wallet browsers provide a convenient and user-friendly interface for individuals to manage their digital assets and engage in cryptocurrency transactions while browsing the internet.
