What is the Coinbase Chrome extension?
The Coinbase Wallet browser extension (often called the Coinbase Wallet extension) is a self-custody wallet that runs in Chromium-based browsers. It lets you interact with decentralized applications (dApps), manage NFTs, perform token swaps, and connect directly to on-chain services — all from your browser while keeping your private keys locally stored in the extension.
Why use the extension?
- Convenience: Access dApps and NFTs directly from your browser without switching to mobile.
- Self-custody control: You hold the keys (recovery phrase) — not a centralized exchange account.
- Hardware wallet support: The extension can integrate with hardware wallets for higher security when signing transactions.
Step-by-step: Install and set up the Coinbase Chrome extension
- Open the Chrome Web Store and search for Coinbase Wallet. Click Add to Chrome and confirm. (Only install official extensions from the store.)
- Pin the extension to your toolbar for easy access.
- Open the extension and choose either Create new wallet or Import existing wallet. If creating, write down the recovery phrase on paper and store it offline.
- Set a strong local password (this protects the extension UI on your device).
- Optional but recommended: connect a hardware wallet (Ledger) for signing high-value transactions.
Security best practices for the Coinbase extension
Browser wallet extensions are powerful — but they can also be a target. Adopt layered protections:
- Never share your recovery phrase — anyone with it can control your funds.
- Use a hardware wallet (e.g., Ledger) for large balances or when interacting with untrusted dApps; the extension supports external signing.
- Enable a strong extension password and use a reputable password manager for long passphrases.
- Use browser profiles: keep your crypto activities in a separate browser profile with minimal extensions installed.
- Avoid public Wi-Fi: when performing sensitive actions always use a trusted network or VPN.
Using the extension safely with dApps and NFTs
When you connect your wallet to a site, the extension will prompt you to approve the connection and any transaction. Follow these rules:
- Confirm the website domain — phishing sites often mimic popular dApps.
- Review transaction details carefully before signing (amount, recipient, gas fees).
- Use token approval tools (or revoke approvals regularly) to limit unlimited spend approvals.
Troubleshooting common extension issues
- Extension not responding: restart the browser, update Chrome, and if needed reinstall the extension after backing up your recovery phrase.
- Unable to connect to a dApp: ensure the site is compatible with Coinbase Wallet and that the extension is allowed to access the page.
- Missing funds after import: check network selection (Ethereum vs. Layer 2), and re-import your wallet using the correct recovery phrase only from the official extension.
What about mobile vs extension?
Coinbase Wallet also has mobile apps. The extension and mobile app can interoperate: you can import a mobile wallet into the extension or vice versa. Mobile apps may offer biometric locks and secure enclave protections that complement the desktop experience.
Recent safety considerations
Extensions and centralized platforms occasionally face incidents. Keep software updated, watch official announcements, and avoid giving sensitive info to anyone claiming to be support. It’s good hygiene to periodically review account and extension permissions and to follow Coinbase’s published wallet security guidance.
When to prefer a hardware wallet or cold storage
For long-term holdings or very large balances, a hardware wallet (or other offline storage) remains the most secure option. Use the browser extension only for everyday interactions and pair it with a hardware signer when possible.
Quick checklist before you transact
- Is the extension up to date?
- Are you on the correct website/domain?
- Have you reviewed the transaction request in full?
- Is your recovery phrase stored offline and secure?
