Browser Wallet
Web3 Infrastructure
Browser Wallet is a type of cryptocurrency wallet that functions as a browser extension, allowing users to manage digital assets and interact directly with decentralized applications (dApps). It securely stores private keys on the user’s device and enables quick access to Web3 features like token swaps, NFT minting, and DeFi protocols. Examples include MetaMask, Rabby, and Phantom.
Use Case: A trader connects their browser wallet to a DeFi exchange to swap tokens quickly, while also using it for NFT minting without relying on centralized exchanges, keeping silver profits liquid.
