Trézor Bridge® | Introducing the New Trezor® App
A simpler connection starts with understanding what happens between your browser, your Trezor device, and the app you trust to manage your crypto.
Your recovery seed belongs on your device—not in a browser or support chat.

01 / THE SHORT VERSION
What is Trezor Bridge?
Trezor Bridge is a lightweight communication service designed to let supported web applications reach a Trezor hardware wallet through a computer. Think of it as a carefully limited messenger: it helps an app discover the connected device and pass requests back and forth, while the device remains the place where sensitive actions are confirmed.
Bridge is not a wallet, an exchange, or a place where coins are stored. It does not replace the hardware wallet, and it should not ask for your recovery seed. The app presents an action; your Trezor displays the important details so you can inspect and approve—or reject—the request on the device.
Does not custody
It is not a hosted wallet, and it is not where your private keys are held.
Device approval matters
Verify transaction details on your Trezor screen before confirming them.
02 / UNDER THE HOOD
A bridge—not a destination.
It helps a supported app speak to your hardware wallet, without becoming the wallet itself.
The app makes a request
A compatible app asks to detect your device or initiate an action. You connect the Trezor and unlock it when prompted.
Bridge carries the message
When required by the software setup, Bridge helps route communication between the computer and the device. It is a connection helper, not an account dashboard.
You verify on-device
For sensitive operations, compare the address, amount, and other details on the Trezor display. Approve only what matches your intention.

The exact connection method depends on the app, browser, operating system, and current Trezor software version. Follow current instructions from Trezor’s official site.
03 / A SAFER FIRST CONNECTION
Get connected with confidence.
Take a moment to confirm the source and check the screen. A careful setup is more useful than a rushed download.
Visit official Trezor Suite Always check the domain before downloading software.Start from an official source
Type Trezor’s official web address yourself or use a trusted bookmark. Be cautious of sponsored search results, look-alike domains, unsolicited messages, and download mirrors.
Check whether Bridge is needed
Open the official Trezor app or follow its current setup instructions. Some environments may handle device communication differently, so do not install extra software just because an unfamiliar page recommends it.
Connect and unlock your device
Use a reliable USB cable and connect directly to your computer where possible. Unlock the device using its normal on-device process. If a prompt looks unexpected, stop and verify it.
Review before every approval
Read transaction details on the hardware wallet itself. The device screen is your final checkpoint; an address shown only on your computer is not a substitute for on-device verification.
✓
Confirm addresses and transaction details on the Trezor display.
✓
Keep device firmware and apps updated using official instructions.
✓
Never share your PIN, recovery words, or backup with support staff.
05 / WHEN SOMETHING DOESN'T CONNECT
Try the simple checks first.
Device detection problems are often ordinary connection issues. Work through these steps without installing unverified utilities.
Check the cable
Some USB cables provide power only. Try a known data-capable cable and a different port, connecting directly rather than through a hub.
Close competing sessions
Close other wallet tabs and apps that may already be using the device. Disconnect, reconnect, then refresh the official app.
Review permissions
Check current operating-system and browser guidance from Trezor. Permission steps can vary; do not follow generic terminal commands from unknown sources.
Verify the software source
Confirm the app and any Bridge installer came from the official Trezor website. Remove suspicious downloads and avoid support links sent by strangers.
Still stuck? Use Trezor’s official help centre and independently navigate to it from trezor.io.
06 / QUICK ANSWERS
Frequently asked questions
Compatibility and app behavior can change over time. Check current official guidance before installing software or troubleshooting.
Is Trezor Bridge the same as the Trezor app?
No. Bridge is a small communication layer that can help supported browser-based interfaces communicate with a Trezor device. The Trezor app is the interface you use to manage your device and accounts. Which software you need depends on the current official Trezor instructions and the app or browser you are using.
Will Bridge ever ask me for my recovery seed?
It should never be necessary to type your recovery seed into a website, chat, or computer app to connect a device. Enter a recovery seed only on the Trezor device itself when the official on-device recovery flow explicitly instructs you to do so. Treat any unexpected seed request as a serious warning.
What should I do if my device is not detected?
Start with the cable and USB port, unlock the device, and close other wallet tabs or applications. Then check the official help centre for current operating-system permissions and Bridge guidance. Avoid downloading replacement drivers or utilities from search ads, forums, or unverified links.
Can I use Bridge on every browser and operating system?
Compatibility can change as browsers, operating systems, and Trezor software are updated. Consult Trezor’s official compatibility and download pages for current support before installing anything. If your app already detects the device, you may not need to install Bridge separately.
THE NEXT STEP IS YOURS
Stay in control of every connection.
Use trusted software, keep your recovery seed offline, and let your hardware wallet be the place where sensitive actions are confirmed.
