What is Trezor Bridge?

Trezor Bridge is an official application from SatoshiLabs (the makers of Trezor) that runs on your computer and acts as a secure translator between web apps (like Trezor Suite or browser wallets) and your Trezor device. It handles USB communication, permissions, and ensures your keys never leave the hardware.

Why Bridge matters

Hardware wallets are secure because private keys remain on the device. But to use them, your computer must send signed requests and receive public data. Bridge ensures that communication happens through a minimal, audited layer that preserves security while providing convenience across operating systems and browsers.

How Bridge works (simple)

  1. Install Trezor Bridge on your computer.
  2. Connect your Trezor device via USB or USB-C.
  3. Open a compatible web app (Trezor Suite, web wallet, dApp).
  4. The web app detects Bridge and requests permission to talk to your device.
  5. You confirm actions on the Trezor device itself — signing transactions, approving addresses, or managing settings.

Installing Trezor Bridge

Supported platforms

Bridge is available for Windows, macOS, and many Linux distributions. Always download Bridge from the official site to avoid malicious software.

Quick installation steps

1. Visit the official Trezor start page and download Bridge. Official Trezor Start

2. Run the installer and follow on-screen instructions.

3. Connect your Trezor and allow the browser or app to communicate with it when prompted.

Troubleshooting common Bridge issues

1. Device not detected

If your Trezor isn't detected: try a different USB cable, check that Bridge is running (system tray or menu bar), and ensure your browser has permission. Rebooting the computer and reconnecting the device often helps.

2. Browser compatibility

Most modern browsers work with Bridge but sometimes browser updates or security settings block communication. If your browser behaves unexpectedly, try an alternative browser or update to the latest version.

3. Bridge update prompts

Keep Bridge up to date. Updates include security improvements and compatibility fixes. Always download updates from the official Trezor start page rather than third-party sites.

Security tip: Trezor will never ask for your recovery seed over the web or Bridge. If any website or support contact requests your seed, treat it as a scam and disconnect immediately.

Best practices when using Bridge

Keep software minimal

Only run Bridge and the specific wallet or dApp you need. Avoid installing unknown browser extensions or software that requests access to hardware wallets.

Use verified links

Always use official links to download or learn about Bridge. Below are several helpful official pages:

When to use Trezor Suite vs Bridge

Trezor Suite is the full desktop/web wallet experience for managing coins, checking balances, and performing transactions. Bridge performs the low-level communication duties. In practice you will often install both: Bridge for connectivity and Suite for user-friendly management.
