What Is Trezor Bridge?
Trezor Bridge is a lightweight application running in the background on your computer. It establishes a safe communication channel between your Trezor device and Trezor Suite (or supported third-party wallets).
Why You Need It
- Guarantees stable USB communication with your wallet.
- Ensures Suite can detect your device immediately.
- Provides fallback support when WebUSB is not reliable.
One-Time Setup
You install Trezor Bridge once. From then on, it runs silently in the background whenever your Trezor is plugged in.
Installation Steps
Step 1: Visit Official Page
Go to Trezor.io/start. The page will detect if Bridge is required.
Step 2: Download Installer
Choose the correct installer for your operating system: Windows, macOS, or Linux.
Step 3: Install & Restart
Run the installer, then restart your browser or Suite. Bridge will start automatically in the background.
Security Tips
- Only download Bridge from Trezor.io — never from third-party sites.
- You do not need to open Bridge manually. It runs as a background service.
- Reinstall when Suite recommends an update to stay secure.
Warning
Fake downloads of “Trezor Bridge” may contain malware. Always confirm the source is Trezor.io/start.
FAQs
Do I always need Trezor Bridge?
Not on every system. Some can use WebUSB, but Bridge ensures full compatibility if WebUSB fails.
Does Bridge store my data?
No. Bridge only relays communication. Private keys never leave your Trezor device.
How can I check if Bridge is running?
If Trezor Suite detects your device immediately, Bridge is working fine in the background.
Can I uninstall Bridge?
Yes, but Suite may fail to detect your device on systems that rely on Bridge.
