Coinbase Wallet Extension® — Getting Started

Coinbase Wallet Extension is a browser-based self-custody wallet designed to give users a convenient way to manage supported crypto assets and interact with decentralized applications (dApps) directly from a compatible web browser. Unlike a custodial exchange account, a self-custody wallet gives the user control over the wallet’s private keys and recovery information. This means users are responsible for protecting their wallet credentials and approving transactions carefully.

For the safest experience, users should always obtain the wallet extension from Coinbase’s official website or the official extension marketplace listing rather than from advertisements, unsolicited messages, or unfamiliar websites. Be particularly cautious of websites that imitate Coinbase branding or ask for a recovery phrase.

What Is Coinbase Wallet Extension?

A wallet extension allows a crypto wallet to operate within a desktop web browser. Once installed and configured, it can be used to connect to supported decentralized applications, view wallet balances, approve transactions, and manage compatible digital assets.

The extension is particularly useful for people who regularly use Web3 services. Instead of manually entering wallet information into every application, users can connect their wallet through the browser extension when the website supports it.

Because it is a self-custody wallet, the security model is different from a traditional Coinbase exchange account. Your wallet credentials are your responsibility. Coinbase cannot simply reset a self-custody wallet in the same way an exchange account password can be reset.

How to Get Started

1. Visit the Official Coinbase Website

Begin by navigating directly to Coinbase’s official website rather than following an unknown link from an email, social-media post, search advertisement, or private message.

Check the website address carefully and make sure you are using Coinbase’s genuine domain. Avoid pages with unusual spellings, extra words, or suspicious domain extensions.

2. Download the Wallet Extension

From the official Coinbase Wallet resources, select the option for the browser extension if it is available for your browser and region. Follow the installation instructions supplied by Coinbase or your browser’s official extension store.

Before installing, verify the publisher and review the extension information. This is an important protection against counterfeit extensions that imitate legitimate cryptocurrency wallets.

3. Create or Import a Wallet

After installation, the wallet may provide options to create a new wallet or restore an existing wallet.

If creating a new wallet, carefully follow the wallet's setup process. You may be shown a recovery phrase or another form of recovery information. This information is extremely sensitive because someone who obtains it may be able to control the assets associated with the wallet.

If importing an existing wallet, use only the official wallet interface and follow its supported recovery process.

4. Secure Your Recovery Information

Your recovery phrase should be treated like the master key to your wallet.

Never share it with another person, website, customer-support representative, or online service. Legitimate support personnel should not need your recovery phrase to help with ordinary troubleshooting.

Avoid storing your recovery phrase in screenshots, public cloud folders, messaging applications, email accounts, or other locations that could be compromised. A secure offline method is generally preferable.

Connecting to Web3 Applications

After the extension has been configured, you can use it with supported decentralized applications.

When a website offers a Connect Wallet option, select the appropriate wallet connection method. The extension should then display the connection request so that you can review it before approving.

Always check the website you are connecting to. A malicious website may attempt to imitate a legitimate dApp or use a misleading transaction request.

Connecting a wallet to a website and approving a transaction are not necessarily the same thing. A connection can allow an application to interact with your wallet, while a transaction may authorize an actual blockchain operation.

Review Every Transaction

One of the most important habits when using a crypto wallet is to review transaction details before approving them.

Pay attention to:

• The website requesting the transaction
• The wallet or account being used
• The asset involved
• The amount being transferred
• Network or blockchain fees
• Any token approvals or permissions being requested
• The destination address, when applicable

Blockchain transactions can be irreversible. If you approve a malicious or incorrect transaction, recovering the assets may not be possible.

Protect Yourself From Scams

Cryptocurrency users frequently encounter phishing websites, fake support accounts, counterfeit wallet extensions, and fraudulent investment offers.

Be suspicious of anyone who asks you to:

• Provide your recovery phrase
• Send cryptocurrency to “verify” your wallet
• Install an unknown browser extension
• Give remote access to your computer
• Approve an unfamiliar transaction
• Transfer assets to a supposedly secure address

A website that looks professional can still be fraudulent. Always verify the source independently before entering wallet information or approving a transaction.

Keeping the Extension Secure

Keep your browser, operating system, and wallet extension updated. Use a strong device password and enable appropriate security protections on your computer.

If your computer is shared with other people, take additional precautions before using a self-custody wallet. Malware and browser-based attacks can create significant risks for cryptocurrency users.

For substantial cryptocurrency holdings, consider researching additional security measures, including hardware-wallet options and secure offline backup practices.

Using Coinbase Wallet Responsibly

Coinbase Wallet Extension can provide a convenient way to access Web3 applications and manage supported crypto assets from a desktop browser. However, convenience does not remove the responsibilities associated with self-custody.

The most important principles are simple: use official sources, protect your recovery information, verify websites, review transactions, and never approve something you do not understand.
