Why Trezor Bridge Exists
Modern browsers can talk to USB devices, but behavior differs by platform and settings. Trezor Bridge provides a consistent, secure pathway so your wallet works smoothly across common operating systems and browsers. If your browser’s native USB support is unavailable or unreliable, Bridge fills the gap and reduces connection errors, timeouts, and failed prompts.
Key Benefits
- Stable Connectivity: Keeps your device connected while performing wallet operations.
- Cross-Platform: Works with major desktop operating systems and mainstream browsers.
- Trezor Suite + Web: Enhances detection for the desktop app and the web version of Suite.
- Secure by Design: No private keys leave your hardware wallet; Bridge only facilitates communication.
- Automatic Updates: Typically updates in the background to maintain compatibility.
How to Install Trezor Bridge
- Go to the official page: trezor.io/start (or the Bridge page linked from there).
- Download the installer for your operating system.
- Close your browser and Trezor Suite if they’re open, then run the installer.
- Reconnect your Trezor device via USB and open Trezor Suite (or the Suite web app).
- Follow on-screen prompts to allow the connection and finish setup.
Tip: If your browser already works perfectly with your device, you may not notice Bridge—That’s fine. It runs quietly and only helps when needed.
Troubleshooting
- Device Not Detected: Replug the USB cable, try a different port, and ensure Bridge is installed and running.
- Browser Prompts Loop: Close all browser windows, restart Bridge (or reboot), then reconnect the device.
- Permission Errors: On first use, allow the browser to communicate with the device; disable conflicting extensions.
- Suite Can’t See Device: Update Trezor Suite and Bridge; keep only one instance (web or desktop) active at a time.
Security Notes
Trezor Bridge never handles your seed or private keys—those remain inside your Trezor device. Always download Bridge from official Trezor links, verify prompts on your device screen, and never enter your recovery seed into any website or software.
