Trezor Bridge — Secure & Smooth Crypto Access

A clean bridge between your Trezor hardware wallet and the web: secure, reliable, and lightning simple.

Version: 2.0.0 • Safe connection

Overview

Trezor Bridge acts as a lightweight, local intermediary that allows your web browser to communicate securely with your Trezor hardware wallet. Instead of exposing sensitive device endpoints to the web, Bridge keeps communications on your machine and presents a minimal, permissioned API to the browser — ensuring your seed phrases and private keys never leave your device.

End-to-end security

All commands to your Trezor device are signed and validated locally. Bridge does not store private keys or transaction data.

Easy setup

Install the Bridge, plug in your device, and follow the browser prompts — typically under two minutes for first-time users.

Broad compatibility

Works with major browsers and popular wallets and dApps that support Trezor's API.

Automatic updates

Bridge can check for updates and notify you when a new secure version is available.

Why it matters

Hardware wallets are the gold standard for holding crypto. Trezor Bridge ensures web applications can interact with your hardware wallet without increasing the attack surface. Because Bridge runs locally, the browser never receives raw key material — only signed transactions when you explicitly approve them on the device.

Quick start

  1. Download and install Trezor Bridge for your OS (Windows / macOS / Linux).
  2. Connect your Trezor device via USB-C or USB-A adapter.
  3. Open your wallet web app (e.g., Trezor Suite or compatible dApp).
  4. Authorize connection on the device when prompted.
  5. Sign transactions only after verifying details on the hardware screen.

Security recommendations

  • Always download Bridge from official sources.
  • Keep your firmware and Bridge updated.
  • Verify URL and SSL certificates before connecting.
  • Never share recovery seed phrases — offline and written on paper are safest.

Frequently Asked Questions

What is Trezor Bridge and why do I need it?+
Trezor Bridge is a small local application that enables secure communication between your browser and your Trezor hardware wallet. It provides a controlled interface so dApps can request signatures without exposing private keys.
Is my wallet data sent to external servers?+
No. Bridge operates locally. Transaction signing and seed handling remain on your device. Only signed transactions (not private keys or seeds) are shared with the requesting web app.
What if Bridge doesn't detect my Trezor?+
Try reconnecting the USB cable, using a different port or cable, ensure Bridge is installed and running, and that your browser is up-to-date. If problems persist, restart your computer and check for device firmware updates.
Can I run Bridge offline?+
Bridge requires a local installation but does not need an internet connection to connect to your device. Some wallet features (like price lookups) may require internet access, but signing can be done offline.
How do I update Bridge securely?+
Download updates from the official Trezor website or use the application's built-in update checker. Verify releases using official signatures if provided.
