Getting started with the Coinbase Extension
This article-style presentation walks you through everything you need to know to install, set up, and use the Coinbase Extension (also referenced as Coinbase Wallet extension or Coinbase browser extension throughout the content).
Overview — What is the Coinbase Extension?
The Coinbase Extension is a browser add-on that acts as a secure wallet and connection bridge between your browser and decentralized applications (dApps). It allows you to store, send, and receive supported assets, manage multiple accounts, connect to dApps via the injected web3 provider, and sign transactions securely. Many people call it the Coinbase Wallet extension — this guide will use both terms interchangeably to make searching easier.
The extension is built for convenience and security: it isolates your private keys locally (encrypted), uses password and optional hardware security, and supports network switching and token management. It is suitable for both casual users who want to swap tokens and developers who need to test dApp integrations.
Why use the Coinbase Extension?
- Easy dApp connection: connect to web apps directly from the browser without exposing private keys on remote servers.
- Local key control: private keys remain on your device and are encrypted with your password or hardware key.
- Backup options: restore using a recovery phrase if you switch devices.
- Integrations: works alongside Coinbase accounts and wallet services for a smoother on/off-ramp experience.
- Developer friendly: injects web3 APIs for testing smart contract interactions and meta transactions.
Prerequisites — what you need before installing
Before you install Coinbase extension, prepare the following:
- A modern browser — Chrome, Edge, Brave, or Firefox are recommended.
- A device you control — installation on shared or public devices is discouraged.
- A secure password manager or secure place to store your recovery phrase.
- Optional: a hardware wallet (Ledger/Trezor) if you plan to use highest-security flows.
Step-by-step: Install the Coinbase Extension
This step-by-step install guide helps you install Coinbase extension and create or restore a wallet.
1. Download from the official source
Open your browser's extension store (Chrome Web Store, Firefox Add-ons, or Edge Add-ons) and search for Coinbase Wallet or Coinbase Extension. Always check the publisher and reviews to confirm authenticity. Click Install or Add to browser.
2. Pin the extension
After installing, pin the extension icon in the toolbar for easy access: click the puzzle icon (extensions) and choose pin next to Coinbase Wallet extension.
3. Create or restore a wallet
Open the extension and choose either Create a new wallet or Restore an existing wallet. When creating a new wallet you'll set a strong password and receive a recovery phrase (a series of words). Write the recovery phrase down offline and store it safely — this is the only method to recover your wallet if you forget your password.
4. Secure your wallet
Enable optional features such as biometric unlock (on supported devices) or guard the recovery phrase with a reliable password manager or physical safe. If hardware wallet support is needed, pair the hardware device per the extension's flow.
5. Add assets & networks
The extension lets you add commonly used assets to the home screen, display token balances, and switch networks (e.g., Ethereum mainnet, testnets, or EVM-compatible networks). You can also add custom RPC endpoints for specialized networks.
How to use the Coinbase Extension with dApps
After setup, connect to a dApp by navigating to the dApp website and choosing Connect Wallet. Select the Coinbase Extension option in the dApp's modal. The extension will pop up, asking you to confirm the connection and choose an account to share. You control which accounts are exposed to the dApp.
When a dApp initiates a transaction, the extension will show a transaction confirmation UI with gas estimates, amount, recipient address, and other metadata. Review carefully. Always inspect recipient addresses and gas fees before confirming.
Security best practices for the Coinbase Wallet extension
Security is critical. Follow these practical safeguards:
- Never share your recovery phrase: support teams never ask for it.
- Use hardware wallets: for high-value holdings, use a hardware wallet that integrates with the extension.
- Verify websites: confirm the dApp domain and avoid unfamiliar or suspicious sites.
- Lock the extension when idle: enable auto-lock and set a short timeout.
- Update regularly: keep extension and browser up-to-date to receive security fixes.
Troubleshooting common issues
Problems occasionally happen — here are common issues and fixes:
- Extension not appearing: restart the browser, re-pin the extension, and check for browser updates.
- Can't connect to dApp: ensure the dApp supports Coinbase Wallet, try clearing site cache or toggling network settings in the extension.
- Missing funds or balances: check the selected network (e.g., you might be on a testnet instead of mainnet) and verify the token's contract address if added manually.
- Forgot password: use your recovery phrase to restore the wallet to a new device.
Advanced: Developer & integration notes
Developers building dApps should detect and support the injected provider from browser wallet extensions. Typical actions include requesting account access, reading chain ID, prompting for transactions, and listening for account/network changes. Always request minimal permissions and provide clear UX for users so they understand what the dApp will access.

Quick FAQs
Is the Coinbase Extension the same as a Coinbase account?
No. The Coinbase Extension (Coinbase Wallet extension) is a client-side wallet for holding keys and connecting to dApps. A separate Coinbase account is an exchange-based account for fiat on/off ramps — you can link them, but they remain different services.
Can I recover my Coinbase Extension wallet if I lose my device?
Yes — restore with the recovery phrase (seed phrase) on a new installation. If you lose both device and recovery phrase, recovery is not possible.
Is the extension safe to use on public Wi-Fi?
While the extension encrypts keys locally, avoid using public Wi-Fi for high-value transactions. Use a secure network or a VPN and enable additional safeguards like hardware wallets.
Frequently Asked Questions — Coinbase Extension
1. How do I install the Coinbase Extension safely?
To install the Coinbase Extension safely: visit your browser's official extension store (Chrome Web Store, Firefox Add-ons, or Edge Add-ons), search exactly for "Coinbase Wallet" or "Coinbase Extension", and verify the publisher information and ratings. Avoid third-party download links. After installing, verify the extension ID or publisher if you want extra assurance, and always keep the extension updated.
2. What should I do if I forget my password?
If you forget your password for the Coinbase Extension, you cannot recover the password itself — but if you have the recovery phrase (seed phrase) you can restore your wallet on another device or fresh installation by choosing the "Restore wallet" option and inputting your recovery words. If you do not have the recovery phrase, recovery is not possible; this is why securely storing the recovery phrase is essential.
3. Can I use a hardware wallet with the Coinbase Extension?
Many extensions support hardware wallets (for example Ledger devices). If hardware wallet integration is supported, use the extension's hardware setup flow to connect and sign transactions through the hardware device. This provides higher security since private keys never leave the hardware device.
4. What networks and tokens does the extension support?
The Coinbase Extension supports multiple EVM-compatible networks (like Ethereum) and many popular tokens. You can add custom tokens by entering their contract addresses if a token doesn't appear by default. For the most accurate list of supported networks and tokens, check the extension settings where networks can be toggled or added.
5. Is the extension safe for DeFi and NFT transactions?
It can be safe when used correctly. For DeFi and NFT activity, follow best practices: verify contract addresses and approvals, use a hardware wallet for large-value operations, limit token approvals where possible, and consider using separate wallet accounts for experimentation and for long-term holdings. Carefully review transaction approvals to avoid granting unlimited allowances to unfamiliar contracts.
