Trézor Bridge® | Introducing the New Trezor® App
Trezor Bridge – What It Is and Why You Need It
Trezor Bridge is a small background program developed by Trezor that allows your Trezor hardware wallet to communicate with your web browser.
It acts as a secure communication layer between your computer and your Trezor device. Without it, older browser-based wallet interfaces may not properly detect or connect to your hardware wallet.
What Does Trezor Bridge Do?
Trezor Bridge enables:
Secure USB communication between your Trezor device and your browser
Device detection for web-based wallet access
Safe transaction confirmation through your hardware wallet
Firmware installation and updates (in supported environments)
It runs quietly in the background after installation and does not require manual operation.
Do You Still Need Trezor Bridge?
If you are using Trezor Suite (the official desktop app), you typically do NOT need Trezor Bridge. Trezor Suite Desktop includes built-in communication drivers.
However, if you are using the web version of Trezor Suite or certain third-party web wallets, Trezor Bridge may still be required for proper device detection.
How to Install Trezor Bridge
To install safely:
- Visit the official Trezor website.
- Go to the Bridge download section.
- Download the version compatible with your operating system (Windows, macOS, or Linux).
- Run the installer and follow the instructions.
- Restart your browser after installation.
Once installed, Trezor Bridge runs automatically in the background.
Common Issues with Trezor Bridge
If your device is not recognized:
Make sure Trezor Bridge is installed and running.
Restart your browser.
Try a different USB cable or port.
Update to the latest version of Trezor Suite.
Restart your computer.
Sometimes browser security settings or extensions can block device communication.
Security Reminder
Always download Trezor Bridge from the official Trezor website only. Fake drivers or modified versions can compromise your security.
Trezor Bridge does NOT ask for:
Recovery seed
PIN
Private keys
If any software requests this information outside your device screen, it is a scam.
Final Thoughts
Trezor Bridge is a lightweight but important component for enabling browser-based communication with your Trezor hardware wallet. While many users now rely on Trezor Suite Desktop (which doesn’t require Bridge), it remains useful in certain web-based setups.
