What is the Coinbase Wallet Extension?
The Coinbase Wallet Extension is a browser companion that lets you securely interact with decentralized applications (dApps), manage crypto assets, and sign transactions without revealing private keys to websites. It provides a local, client-side wallet experience separate from centralized exchange accounts — putting you in control of your keys while making on-chain interactions smooth and fast.
Private keys and seed phrases remain stored locally and encrypted on your device. The extension requests signatures but never exposes your keys to websites.
Connect to marketplaces, games, DeFi platforms, and NFT galleries with a single click. The extension injects a secure provider into pages that request wallet access.
Switch networks and manage assets across supported chains. The extension lets you add custom networks for chains compatible with Ethereum standards.
Every transaction is surfaced in the extension with a clear summary — amounts, recipient, gas fees and permissions — so you can approve or reject confidently.
How to install and set up
Quick steps — compatible with Chrome, Edge, Brave, and other Chromium-based browsers.
- Open your browser’s web store (e.g., Chrome Web Store).
- Search for “Coinbase Wallet extension” and confirm the publisher/official listing.
- Click Add to browser and pin the extension for easy access.
- Open the extension, create a new wallet or restore an existing one using your seed phrase.
- Set a strong password for local access and securely store your recovery phrase offline.
Security best practices
Using a wallet extension comes with responsibilities. Keep your recovery phrase offline and never share it. Use hardware wallets for large balances and review every signature request carefully. Beware of phishing sites — always check the URL and never connect to unfamiliar dApps.
Common use-cases
- Buying, storing, and sending tokens.
- Connecting to NFT marketplaces and minting or trading digital art.
- Accessing DeFi protocols for lending, staking, or swapping tokens.
- Playing blockchain games or participating in DAO governance.
Design & UX highlights
The extension balances simplicity and power: clear language in transaction prompts, an easy asset overview with balances and recent activity, and quick network switching. These reduce friction for new users while keeping advanced controls available for experienced traders.
Privacy considerations
Wallet extensions must interact with websites to function, which can reveal public addresses and transaction history. If privacy is a priority, consider using new addresses per dApp and mixing strategies that comply with local laws. Remember that on-chain activity is public by design.
Troubleshooting tips
- If a dApp won't detect the extension, try refreshing the page or toggling the extension off/on.
- Clear site data or check for browser updates if connectivity issues persist.
- For transaction failures, check gas settings and the destination address carefully before retrying.
Accessibility
Many wallet extensions are improving keyboard navigation and screen reader support. If accessibility is critical for you, test the extension’s interface or consult the extension developer’s accessibility documentation.
