When connecting Phantom to an app (dApp), the app can see your public address and ask you to approve actions such as signing messages or submitting transactions. Only connect to apps you trust.
Note: Phantom does not support connecting to apps on Bitcoin.
Browser extension
Find the app in Explore or go directly to its site in your browser.
- Open the app. From Explore, search for the app by name. From your browser, go to the app's URL directly.
- In the app, click Connect or a similar option, then choose Phantom.
- Review the details and click Connect.
- If prompted, approve a Sign message request to finish connecting.
Before approving any request from an unfamiliar site, verify the URL carefully.
If the connection succeeds, the app will usually show that your wallet is connected.
Mobile app
On mobile, connecting only works inside Phantom's in-app browser. You can't connect from Safari, Chrome, or other mobile browsers.
- Tap the search bar at the bottom of the screen, then enter the app's name or URL and open it.
- In the app, tap Connect or a similar option, then choose Phantom.
- Review the details and tap Connect.
- If prompted, approve a Sign message request to finish connecting.
If the connection succeeds, the app will usually show that your wallet is connected.
View apps you connected to
Go to Settings → Connected Apps. Each platform only shows the apps you connected to on that platform. Apps you connected to on desktop won't show in the list on mobile, and vice versa.
Common issues
I don't see a connection popup
Browser extension: quit and reopen your browser, then try again. If you're using Safari, switch to Chrome — Safari isn't supported.
Mobile app: you may be trying to connect from an external browser. On mobile, connecting only works inside Phantom's in-app browser. Use the search bar to open the site inside Phantom.
I see "Failed app interaction," "Couldn't connect," or get stuck on "Connecting"
These errors are often temporary. Quit and reopen your browser, then try again. If the problem persists, reset Phantom.
I see a "null" error when trying to connect
The extension may be in a bad state, or your browser may be blocking the connection.
- Quit and reopen your browser.
- If the issue seems to be with the app, clear your browser cache or the site's cookies, then try again.
- If the problem persists, reset Phantom.
I want to use a mobile browser instead of Phantom's in-app browser
This isn't supported. Other mobile browsers may redirect you to download Phantom, which is expected. Use the search bar to open the site inside Phantom instead.
