Coinbase Wallet is a self-custody cryptocurrency wallet that allows users to securely store, manage, and trade a wide range of digital assets, including cryptocurrencies like Bitcoin, Ethereum, and ERC-20 tokens. Unlike the main Coinbase app, which is a centralized exchange, Coinbase Wallet is a non-custodial wallet, meaning users have full control over their private keys and digital assets. The wallet also supports decentralized applications (dApps) and NFTs, providing a gateway to the decentralized web. It is available as a mobile app and browser extension, ensuring accessibility and ease of use for both beginners and experienced crypto enthusiasts.
