01 / THE BASICS
A small helper.
A more direct connection.
Trezor Bridge is software that lets a supported web browser communicate with a Trezor hardware wallet connected to your computer. When a wallet website needs to interact with your device, Bridge helps pass messages between the browser and the wallet.
It works in the background; it is not a wallet, an account, or a place where coins are stored. Your Trezor remains the device that displays and confirms sensitive actions. The exact setup can vary with your operating system, browser, device, and the wallet interface you use.
02 / THE CONNECTION
Two sides. One clear route.
Bridge is the communication layer—not a substitute for reviewing what your device shows.
Browser compatibility
It can help where a browser needs an additional communication method. Follow current guidance for your specific setup.
Security stays deliberate
Review transaction details on the hardware wallet itself and approve only what you recognize and intend.
Reliable device dialogue
When the required software is present and current, your wallet interface can detect and request communication with the device.

03 / GET CONNECTED
A thoughtful setup, step by step.
Use official Trezor resources for downloads and device-specific instructions. These general steps help you know what to expect.
Start with the official source
Open the official Trezor website directly. Check the address carefully, then locate current Bridge instructions for your operating system and wallet interface.
Install for your system
Download only from the official source and follow its installation steps. Allow any requested permissions only when they match the documented setup.
Reconnect and open your wallet
Connect the Trezor with a data-capable USB cable, unlock it as prompted, then open the supported wallet interface. Keep the device attached while it is in use.
Check detection and verify
If prompted, select the device and follow on-screen directions. Before approving any action, compare the details on your Trezor screen with what you intended.
A NOTE ON SAFETY
Your device is the final check.
Never share your recovery seed with a website, app, support agent, or anyone else. Bridge setup should not require you to enter it online. Confirm addresses, amounts, and other transaction details on the Trezor screen before approving. If something seems unexpected, stop and verify through official documentation.
04 / WHEN THINGS GO WRONG
Not seeing your device?
Try the basics first, then check the latest official troubleshooting guidance.
Find official helpCheck the cable and port
Some USB cables only provide power. Try a known data-capable cable, another direct port, and reconnect the device.
Refresh your connection
Close wallet tabs, reconnect your Trezor, then reopen the wallet interface. Avoid using several wallet interfaces at once.
Review software and access
Confirm Bridge is installed and current per official instructions. Browser permissions or security software can affect device detection.
Update with care
Use only official Trezor sources for software or firmware updates. Read prompts closely and do not interrupt an update in progress.
05 / GOOD TO KNOW
Questions, answered.
Quick, straightforward answers to common Bridge questions.
Is Trezor Bridge a wallet?
No. Bridge is a communication tool that helps supported browser interfaces connect to a Trezor device. It does not hold funds or replace the hardware wallet.
How can I tell whether the device is detected?
Your wallet interface may show the connected device or ask you to select it. Follow the instructions shown by the official wallet interface and check that the Trezor itself is unlocked if needed.
Should I enter my recovery seed to install Bridge?
No. Never enter your recovery seed on a website or into Bridge. Keep it private and follow official Trezor recovery guidance only when you intentionally need recovery.
Does every user need Bridge?
Not necessarily. Requirements can depend on browser, operating system, device, and wallet interface. Check the official documentation for your exact combination.
Where should I get updates?
Go directly to the official Trezor website for current Bridge or firmware instructions. Avoid download links in unsolicited messages and verify web addresses.
