Learn how the Phantom browser extension works, how to install it, supported browsers, useful features, security tips, troubleshooting, FAQs, and more. The Phantom Extension is a browser-based tool that brings Web3 features directly into your desktop browsing experience. Instead of repeatedly moving between different applications, users can open Phantom from the browser toolbar and interact with supported decentralized applications.

Phantom currently recommends Google Chrome for its browser extension. It can also work with Chromium-based browsers such as Brave, Opera, and Microsoft Edge, although Phantom says these browsers are not officially supported to the same level as Chrome. Firefox and Safari are currently not supported.

Phantom has become popular among Web3 users because it provides a straightforward interface for interacting with blockchain applications.

Some useful capabilities include:

• Connecting with supported dApps

• Viewing balances and digital assets

• Reviewing transaction requests

• Exploring supported Web3 applications

• Swapping supported assets

• Managing connected applications

• Using popup or side-panel mode in the browser

The extension can open as a small popup or as a side panel that remains visible while you browse between tabs.

Getting started is relatively simple:

1. Visit the official Phantom download page.

2. Select the desktop/browser option.

3. Choose Chrome if you're using the recommended browser.

4. Add the extension through the browser's official extension store.

5. Open the Phantom icon from your browser toolbar.

6. Follow the setup instructions shown on screen.

Phantom strongly recommends downloading the extension only from phantom.com/download, because fake extensions can be used to steal sensitive information or funds.

Once the extension is ready, you can visit a compatible decentralized application and select Connect or a similar option.

Before approving a connection, take a moment to verify the website and understand what information or permissions are being requested. Phantom notes that connected applications can see your public address and may request signatures or transactions.

You can also manage connected applications through Phantom's settings and revoke signing permissions when necessary.

Security is one of the most important parts of using any Web3 service.

Phantom provides features such as transaction previews, scam detection, and blocklists to help identify potentially dangerous activity. Transaction previews can provide warnings when a transaction appears suspicious.

However, these protections should not replace your own judgment.

Always:

• Download Phantom from the official source.

• Check the domain before connecting.

• Never share your Secret Recovery Phrase.

• Don't enter recovery information into random websites.

• Review transaction details before signing.

• Avoid links received through suspicious DMs or advertisements.

Phantom explicitly states that its support team will never ask for your Secret Recovery Phrase.
