Coinbase Chrome Extension — Official Guide to Setup & Use

On first launch, you'll be guided through a short onboarding: permissions explanation, account linking, and notification preferences. Choose conservative notification settings if you prefer privacy.

Enable 2FA if not already enabled 🔐

Coinbase recommends enabling two-factor authentication (2FA) — SMS, authenticator app, or hardware key. Hardware keys are best for strong security.

Permissions & least privilege

Extensions request permissions. Coinbase extension should request only the permissions necessary to operate — typically "activeTab" or specific host permissions for dApp interactions. If the extension asks for broad access (e.g., read all data on websites), double-check the official listing and reviews. 🕵️‍♀️

Private keys & phrases

Never enter private keys or seed phrases into your browser except into a verified, offline wallet restoration flow. Coinbase extension is typically custodial-friendly; it may not require seed phrase entry. If you see a request for your seed phrase, treat it as suspicious. 🚨

Extension not visible after install

Go to chrome://extensions and ensure the extension is enabled. Pin it via the extensions menu if necessary. 🔍

dApp won't connect

Ensure the site is trusted. Refresh the page, click the extension, and approve the connection prompt. Also confirm network selection matches (e.g., Ethereum mainnet vs testnet). 🌐

Transactions failing or stuck

Check network status. Gas or fee settings may be inadequate; increase the fee or retry. Verify recipient address and chain compatibility.

Coinbase, as a licensed financial services company, adheres to privacy and regulatory requirements. The extension is a client of Coinbase APIs. Sensitive actions (signing, transfers) will require explicit confirmation.

Always consult Coinbase’s official privacy policy and the extension's listing details for up-to-date info.

• Use semantic HTML and ARIA where appropriate.
• Provide keyboard navigation for all interaction flows (tab focus, button activation via Enter/Space).
• Ensure color contrast meets WCAG guidelines — this template uses orange on dark backgrounds with high contrast for readability.
• Internationalization: store strings externally and provide RTL support if necessary.

Is the extension official?

Always verify the publisher on the Chrome Web Store. Official Coinbase extensions will list Coinbase, Inc. as the publisher and link to official Coinbase domains.

Will Coinbase ever ask for my password or seed phrase inside the extension?

Coinbase may request sign-in but will not ask for private seed phrases via unsolicited prompts. Treat any unexpected seed phrase request as a phishing attempt. 🔒

Can I use the extension with hardware wallets?

Some features may integrate with hardware wallets; check the extension documentation and Coinbase's help center for the latest hardware wallet support details.

How to report suspicious activity?

Contact Coinbase support and use the reporting link in the Chrome Web Store listing. Document the suspicious flows and, if possible, take screenshots (without sharing sensitive data).📝

1) Installing from the Chrome Web Store

Open the Chrome Web Store: https://chrome.google.com/webstore. Search for "Coinbase". Confirm publisher and version details. Click Add to Chrome. On the permission prompt, inspect requested permissions. A safe extension will ask only for things it needs — avoid extensions requesting unnecessary access to all websites, or to read and modify data on all websites unless explicitly required and justified.

2) Pinning & initial sign-in

After the extension installs, click the extensions icon (puzzle piece) in the toolbar and pin Coinbase for easy access. Click the Coinbase extension icon and choose "Sign in". Complete email verification and any required 2FA. If you see a request for a recovery phrase, treat with extreme suspicion.

3) Interface tour

The extension should present a tidy dashboard: balances, recent transactions, a "Connect" button for dApps, and a settings gear. Click each area and note available actions. If the extension provides a "Learn more" or help link, use it to check official documentation.

4) Connecting to dApps

When you connect to a dApp, the extension will present a popup asking which account/address to share. Review the request carefully. Only approve the minimal set of permissions required. If a dApp requests token approvals (spend allowances), be aware that approving unrestricted allowances can expose funds — prefer specific allowances when possible.

5) Sending funds

Initiate sending by selecting an asset and clicking "Send". Enter the recipient address, amount, and (if available) the network. Review fee estimates and total cost before confirming. Double-check long addresses by copying them to a secure text editor and verifying prefix/suffix, or by using address book features if available.

6) Receiving funds

Generate a receive address from the extension. Some assets have unique chain addresses; ensure the sender uses the correct chain. Display a QR code if provided for quick mobile scanning.

7) Settings & preferences

Open settings to adjust notification preferences, network options, default accounts, and security choices. Lock the extension after X minutes if you are in a shared environment. Enable additional prompts for every send if you want stronger safety checks.

8) Lock & logout

Use the lock or logout feature when you step away. Pin the extension only on personal devices. Do not leave the extension logged in on public or untrusted machines.

9) Backups & account recovery

If Coinbase provides a recovery method or suggests linking to verified email/phone, follow those practices. For wallets that expose seed phrases, store them offline in a secure location — hardware devices, encrypted vaults, or physical backups like steel plates for long-term resilience.

10) Updates & release notes

Keep the extension updated. Check release notes on the store listing or GitHub (if open source). Updates may include security patches, new features, and deprecations.

The above steps form a long, repeated, detailed pattern that ensures you understand every aspect of the extension from install to everyday operations. Keep practicing in small amounts and use sandbox/testnet modes if you are trying new dApps or unfamiliar flows.

1. Verify extension publisher and reviews before installing. 🕵️‍♂️
2. Enable 2FA and use hardware keys where possible. 🔐
3. Use a separate browser profile for crypto activities. 👤
4. Pin the extension and keep your browser updated. 🔄
5. Keep small test transactions when trying new dApps. 🧪
6. Use ledger or hardware wallets for large holdings. 💼
7. Regularly review connected websites and revoke access for unused dApps. 🔗
8. Backup recovery phrases offline in multiple secure places. 🗝️

Crypto regulations vary across jurisdictions. Coinbase operates under compliance frameworks in regions it supports. Users should understand tax obligations, reporting requirements, and local laws. For formal advice, consult a qualified legal or tax professional.

• Address: A public string used to receive crypto. 🎯
• Gas: Fee paid to miners/validators to process transactions. ⛽
• Seed phrase: A human-readable backup for private keys. 🗝️
• dApp: Decentralized application connecting via wallet extensions. 🌐

Open Chrome DevTools and inspect background scripts, service workers, or extension pages. Use console logs and network traces to identify issues. When reporting bugs, include console traces and steps to reproduce.

Lost device

Log into Coinbase on another trusted device and revoke sessions for the lost device. Rotate passwords and review account activity. If you used a hardware wallet, recover onto a new hardware device using your seed phrase if needed.

Compromised account

Contact Coinbase support immediately. Freeze or withdraw funds to a cold wallet if possible. Change passwords and revoke third-party app access.

Workflow A — Paying with crypto on a web checkout

1. Choose the crypto payment option on checkout. 💳
2. The checkout site prompts the extension to prepare a payment request. 🔗
3. Open the extension, confirm details (amount, recipient, memo) and approve the transaction. ✅
4. Monitor the transaction status on the extension history and on-chain explorer. 🔍

Workflow B — Connecting to a DeFi dApp

1. Open the dApp and click "Connect Wallet". 🌐
2. Choose Coinbase extension; approve the requested account and permissions. 🔐
