Works with modern browsers on Windows, macOS & Linux

Trezor Bridge

Trezor Bridge is a lightweight background service that lets your web browser talk to your Trezor hardware wallet. It replaces unreliable USB drivers with a secure, local connection so you can manage crypto assets through supported apps and websites.

Fast, driver‑free setup

No complex drivers. Install once and your browser can detect your Trezor instantly.

Local & secure

Runs locally on your machine and only bridges data to authorized pages you open.

Automatic updates

Stays up to date to keep compatibility with browsers and Trezor firmware.

How it works

Bridge between USB and your browser

After installation, Trezor Bridge starts a small background service on your computer. When a supported webpage or app needs access to your device, it talks to the Bridge locally (not over the internet). The Bridge forwards only the necessary messages to your Trezor via USB, and your device displays all sensitive prompts for verification.

  • No private keys leave your Trezor—ever.
  • Permissions are limited to pages you open and approve.
  • Works across major browsers that support WebUSB alternatives.

Linux

Install on Linux

Install the package for your distro (e.g., .deb or .rpm).
Add udev rules so the system can access the device over USB.
Reload udev and reconnect the device.
# Example: create /etc/udev/rules.d/51-trezor.rules
SUBSYSTEM=="usb", ATTR{idVendor}=="534c", MODE="0666", GROUP="plugdev"
SUBSYSTEM=="usb", ATTR{idVendor}=="1209", ATTR{idProduct}=="53C0", MODE="0666", GROUP="plugdev"
SUBSYSTEM=="usb", ATTR{idVendor}=="1209", ATTR{idProduct}=="53C1", MODE="0666", GROUP="plugdev"
# then: sudo udevadm control --reload-rules && sudo udevadm trigger
After install

Quick checks

Bridge running? Look for a background service/process named like Trezor Bridge.
Browser restart: If your device isn’t detected, close all windows and reopen.
USB cable: Use the original, data‑capable cable and a direct port (avoid hubs).
Firmware: Keep your Trezor firmware and wallet app up to date.
Troubleshooting

Device not detected?

  • Ensure the Bridge is installed and running. Reinstall if corrupted.
  • Try a different USB port or cable; avoid USB hubs and adapters.
  • Close other apps that may lock the USB device (VMs, other wallets).
  • On Linux, verify your udev rules and group membership.
  • Confirm your browser supports the connection method used by your wallet.
Security

Stay safe while installing

  • Only download from the official Trezor website and verify the URL.
  • Never install from ads, random forums, or emailed links.
  • Your seed phrase is never needed to install software.
  • If something feels off, disconnect your device and investigate.

FAQ

Do I need Trezor Bridge if WebUSB works in my browser?

Some browsers support WebUSB directly, but the Bridge improves reliability and compatibility across platforms and wallet apps. Many users prefer it for a smoother experience.

Is Trezor Bridge open source?

The Bridge and related tooling have open components. Check the official Trezor repositories and documentation for details and licenses.

Does Bridge expose my private keys?

No. Your private keys stay inside your Trezor hardware wallet. The Bridge only passes signed/unsigned messages between your browser and the device.

How do I remove or reinstall it?

Use your OS’s standard uninstall method. Then reinstall from the official website. A reboot or browser restart may help finalize removal.
