Introduction
Coinbase Wallet extension brings secure crypto wallet functionality directly into your Chrome browser. It allows users to manage private keys, interact with decentralized applications (dApps), sign transactions, and seamlessly connect web-based apps to their on-device wallet — all from a lightweight browser extension. This presentation covers the product overview, setup flow, UX patterns, security considerations, Chrome Web Store listing best practices, and supporting resources.
Why a browser extension?
- Conveniently connect to web dApps without exposing private keys to websites.
- Streamlined user experience for frequent traders, NFT collectors, and DeFi users.
- Faster interaction and transaction signing compared to mobile workflows when working on desktop.
Key Features
- Account Management: Create, import, and manage multiple wallet accounts within the extension.
- Secure Key Storage: Private keys are encrypted locally; recovery phrases are shown only once during setup.
- dApp Connect: Connect to websites using WalletConnect or native provider injection for seamless interactions.
- Transaction Signing: Approve or reject transactions with clear breakdowns of gas fees and destination addresses.
- Token & NFT Management: View, send, and receive tokens and collectibles across supported networks.
- Network Support: Ethereum mainnet and major EVM-compatible networks with switchable RPC endpoints.
- Privacy & Permissions: Granular controls over which websites can connect to the wallet and when.
- Onboarding Flow: Guided seed phrase backup, password protection, and optional biometric unlock where supported by the OS/browser.
Chrome Web Store Listing Highlights
- Clear extension title and short description emphasizing security and convenience.
- High-quality screenshots demonstrating the connect experience, transaction flow, and token list.
- Concise bullets describing permissions, privacy, and what users can expect during install.
- Up-to-date support URL and privacy policy links.
Installation & First-Time Setup
Step 1 — Download from Chrome Web Store
Search for "Coinbase Wallet" in the Chrome Web Store or use the direct listing link. Verify publisher name and number of users/reviews to reduce the chance of installing impersonators.
Step 2 — Add to Chrome
Click "Add to Chrome" and review the permissions popup. Confirm that you want to add the extension and pin it to the toolbar for quick access.
Step 3 — Create or Import Wallet
- Create a new wallet: Choose a strong password and write down the recovery phrase shown on-screen. Store it offline and never share it.
- Import an existing wallet: Use your recovery phrase to import wallets created elsewhere (ensure you’re importing to the official extension).
Step 4 — Backup and Verification
After creating/importing, users are guided to back up their seed phrase. The UI should display clear warnings that anyone with the seed phrase can access funds, and recommend multiple backup locations (hardware wallet, paper, secure vault).
User Interface & Interaction Patterns
Toolbar Popup
The primary UI is a compact popup opened from the Chrome toolbar. It shows account balance, quick-send buttons, and recent transaction history. Use progressive disclosure to avoid clutter — show the most important actions prominently.
Transaction Modals
When a dApp requests a signature or transaction, a modal details the request: from address, to address, value, network fees, and any contract data. Provide an expandable "Advanced details" section for power users and a clear "Reject" button to abort suspicious requests.
Connected Sites Page
A settings panel lists connected websites with the ability to remove access, set per-site permissions, and view historical interactions. Showing timestamps and the exact permissions granted increases user transparency and trust.
Visual Design
Use an accessible color palette with high contrast for text and controls. Icons and microcopy should reduce ambiguity — e.g., "Approve" vs "Sign" vs "Send" should have consistent meanings across the UI.
Security Model & Best Practices
Local Encryption
Private keys and seed phrases are encrypted locally using the user’s password. The extension should never transmit unencrypted private keys or recovery phrases over the network.
Phishing Protection
- Implement domain whitelisting and warning banners when interacting with unknown domains.
- Display the exact domain requesting the connection and block if mismatch or redirection occurs.
- Provide in-extension educational content about phishing and scams.
Permissions Minimization
Ask for the minimum permissions required. If the extension needs to inject a provider into the page, limit it to active tabs only and allow the user to opt-in per-site.
Hardware Wallet Support
Offer integration with hardware wallets (Ledger, Trezor) so users can sign transactions externally. This reduces exposure of private keys on the host machine even if the extension is compromised.
Chrome Permissions & Privacy Considerations
Chrome extensions request permissions that affect user trust. The extension manifest must list only the necessary permissions and provide clear, plain-language explanations on the listing and during install.
Common Permissions
| Permission | Why it's needed |
|---|---|
| ActiveTab | To allow the extension to interact with the current page when the user initiates a connection. |
| Storage | To securely store encrypted keys, settings, and preferences. |
| Notifications | To inform users about completed transactions or security alerts. |
Privacy Policy & Data Handling
Provide a transparent privacy policy that explains which data is kept locally, which is transmitted (e.g., analytics, optional crash reports), and how users can opt out. Prefer anonymized analytics if any telemetry is collected and allow users to disable it during onboarding.
Best Practices for Chrome Web Store Listing
Title & Short Description
Use a clear title like "Coinbase Wallet — Secure Browser Extension" and a short description emphasizing security, dApp connectivity, and ease of use.
Screenshots & Video
- Include high-resolution screenshots for the toolbar popup, connect flow, transaction modal, token list, and settings page.
- Add a short 30–60 second explainer video showing a secure connect and a simple token send.
Support & Documentation
List a support URL, clear help articles, and links to community resources. Quick troubleshooting guides reduce support volume and increase user satisfaction.
Changelog & Release Notes
Keep an up-to-date changelog in the store listing for transparency. Highlight security fixes and compatibility updates prominently.
Frequently Asked Questions
Is the extension safe?
Yes — when obtained from the official Chrome Web Store listing by the verified publisher. Keys are encrypted locally and never shared. Users should validate the publisher and check reviews to avoid fake extensions.
Can I import a wallet from mobile?
Yes — using the 12/24-word recovery phrase you can import wallets created on the Coinbase Wallet mobile app or elsewhere.
How do I disconnect a dApp?
Open the extension, go to Connected Sites, and remove the site. This revokes future access until the user connects again.
What should I do if my extension is compromised?
- Immediately move funds to a secure wallet (ideally hardware) you control.
- Revoke connected sites and change passwords for associated accounts.
- Contact support and follow their incident response guidance.
