Coinbase Wallet — Browser Extension (Demo content)

Coinbase Wallet is a lightweight, user-first browser extension that puts you in control of your keys and your crypto experience. Install it in seconds, connect to a wide range of decentralized applications, and safely sign transactions without exposing private keys to remote services. This extension is designed to be intuitive for beginners while offering advanced controls for power users.

At its core, the extension provides a protected vault for private keys, a clean transaction confirmation flow, network visibility, token management, and NFT previews. Security features include encrypted local storage, optional hardware wallet integration, and a transaction detail view that helps you verify gas fees and contract interactions before approving anything.

The wallet supports multiple networks out of the box, with network switching in one click. Developers can connect via injected provider APIs, and the extension exposes clear permission prompts when a site requests access. For teams and builders, seamless testnet toggles and developer tools make it simple to work locally and on public test networks.

Everyday convenience features include in-extension token swaps, transaction history, customizable gas presets, and a fast QR scanner for mobile pairing. Onboarding helpers, tooltips, and safety nudges guide users through the most common pitfalls — such as double-checking URLs and avoiding phishing attempts.

Privacy-respecting design choices ensure that metadata does not leave the extension unnecessarily. Local-only key derivation, optional seed phrase export, and granular permission scopes create a predictable, auditable security model. For additional hardening, advanced users may enable two-factor confirmations, require password re-entry, or opt into hardware-backed signing.

The extension also includes a built-in token discovery mechanism, letting you add tokens by contract address, search by symbol, or import lists. For collectors, NFT thumbnails, metadata, and marketplace links are surfaced in a concise gallery view so you can inspect holdings quickly and safely.

Finally, the extension is designed for transparent updates: release notes are shown in the UI, and critical security patches are highlighted at first launch after update. We recommend always keeping the extension updated and verifying any unexpected UI changes with official release notes or the extension store's changelog.
