Trezor Bridge

A secure, lightweight bridge that connects your Trezor hardware wallet to desktop apps and supported browsers.

What is Trezor Bridge?

Trezor Bridge is a small background application that enables communication between your Trezor hardware wallet and desktop platforms. It acts as a secure, USB-to-browser interface so that web-based wallet interfaces and desktop clients can interact with your device without exposing private keys.

Why use Bridge?

Bridge provides a frictionless connection while keeping security at the forefront. It avoids browser USB API restrictions, offers automatic updates, and supports multiple operating systems so you can manage your crypto from familiar apps and web wallets safely.

Core features

Secure communication

Encrypted channels and strict device authorization keep interactions between your computer and the Trezor isolated and auditable.

Cross-platform

Available for Windows, macOS and Linux with simple installers and minimal system requirements.

Automatic updates

Bridge can check for updates and ensure you get the latest compatibility and security fixes without manual effort.

Small footprint

Lightweight background process that consumes modest resources and runs only when needed.

How it works (simple)

When installed, Bridge runs in the background and exposes a local endpoint that browser-based wallets and compatible desktop apps access through a secure handshake. You approve every transaction on your Trezor device — private keys never leave the hardware.

Security best practices

  • Download Bridge only from official sources.
  • Keep your Trezor firmware up to date and verify device model at setup.
  • Never share your recovery seed. Bridge never asks for it.
  • Approve transactions physically on the device; don’t rely on screen prompts alone.

FAQ

Do I need Bridge to use my Trezor?

For many desktop and browser-based wallets, yes — Bridge provides the secure channel required for functionality. Some native apps have direct support and may not require Bridge.

Will Bridge ever access my seed phrase?

No. Bridge only facilitates communication. Your seed and private keys remain stored on the Trezor device and never leave it under normal operation.

How do updates work?

Bridge can notify you of updates and optionally perform them. You can always download the latest installer manually from official sources.

Troubleshooting tips

If your device isn't detected: check the USB cable, restart Bridge, try another USB port, or consult the logs in the Bridge settings panel.
