trezor bridge — Secure Connection for Your Trezor Device

Trezor Bridge links your hardware wallet to desktop browsers and apps securely and locally. No cloud, no remote keys — just a fast, private channel that makes using your Trezor effortless.

What is Trezor Bridge?

Trezor Bridge is a lightweight application that runs on your computer and creates a trusted, encrypted connection between your Trezor device and compatible web applications. It replaces direct USB-browser communication with a secure local proxy, ensuring compatibility across browsers and operating systems.

Why you need it

1
Reliable browser support
Modern browsers restrict direct USB access for security reasons. Trezor Bridge ensures seamless interaction across Chrome, Firefox, Edge, and others.
2
Local & private
All communication stays on your device and machine — Bridge never sends your device data to remote servers. Your private keys remain on the Trezor hardware.
3
Easy installation
Install in minutes on Windows, macOS, or Linux. Automatic updates keep Bridge current with security fixes and browser changes.

Quick install & setup

  1. Download the official Trezor Bridge installer for your OS.
  2. Run the installer and allow the application to start in the background.
  3. Open your browser and connect your Trezor device — the site will detect Bridge automatically.
  4. Follow on-screen prompts to confirm device actions directly on your Trezor.

Troubleshooting

  • If Bridge isn't detected, ensure it is running (check system tray / background apps).
  • Allow the installer through your OS firewall or security prompts.
  • Restart Bridge or your browser if the device isn't recognized.
  • Use official downloads only — avoid third-party installers.

Built for simplicity, engineered for security

Trezor Bridge is a small but essential component of the Trezor ecosystem. It removes compatibility friction between browsers and hardware wallets while protecting your keys through local-only communication. Whether you’re a frequent trader or holding for the long term, Bridge helps you interact with web services confidently and smoothly.
