Trezor Bridge — Secure, Simple Communication for Your Hardware Wallet

Trezor Bridge is the official connector that lets your Trezor hardware wallet safely communicate with Trezor Suite and supported browser apps.

What is Trezor Bridge?

Trezor Bridge is a lightweight background application that creates a secure channel between your computer and your Trezor device. It replaces legacy browser plugins and provides a stable, cross-platform bridge so that web apps and desktop software can detect and talk to your Trezor wallet.

The Bridge handles USB communication while making sure private keys and sensitive operations remain inside the hardware device — the Bridge only forwards encrypted messages.

Why you need it

  • Compatibility: Works with modern browsers and desktop apps without additional plugins.
  • Security: Keeps private keys on the device; the Bridge never accesses them.
  • Reliability: Stable connection that reduces device-detection issues and improves user experience.
  • Cross-platform: Available for Windows, macOS, and Linux.

How to install & use

1. Download the official installer for your operating system from the Trezor website.
2. Run the installer and follow on-screen instructions. A restart of your browser may be required.
3. Connect your Trezor device with a USB cable. Open Trezor Suite or a supported app and follow prompts to connect.

Security tip: Always download Trezor Bridge from the official source and verify URLs to avoid counterfeit software. Never share your recovery seed with anyone.

Quick troubleshooting

If your device isn’t detected: try a different USB cable or port, restart the Bridge service, or reinstall Bridge. For persistent issues consult official Trezor support documentation.

Example command (Linux) to restart the Bridge service: systemctl --user restart trezord
