Trezor Bridge® — Secure Your Hardware Wallet

Trezor Bridge® enables secure communication between your Trezor device and Trezor Suite or supported browser apps. Install Bridge to connect safely and manage your crypto.

Overview

Trezor Bridge is a lightweight, official connector that runs on your computer and enables the Trezor device to communicate with local apps and the browser. It handles USB communication securely so your private keys never leave the device.

How Bridge works

Runs locally on your machine and exposes a secure, local HTTPS endpoint for Trezor Suite and authorized browser pages to communicate with your device.
Only accepts connections from trusted, signed apps or origins; prompts on the device confirm every sensitive operation.
Does not transmit private keys or recovery seeds—those remain inside the hardware wallet.

Quick note: Bridge is required for legacy browser integrations and still recommended for smooth device detection across platforms. Modern Trezor Suite desktop apps may use native drivers where available.

Download & install

Choose the installer below that matches your operating system. Always download Bridge from the official source.

Installation steps

Download the correct installer for your operating system.
Run the installer and follow on-screen prompts (administrator privileges may be required).
Restart your browser or Trezor Suite after installation.
Connect your Trezor device with a compatible USB cable and follow on-device prompts.

Permissions & privacy

Bridge only listens on localhost and requires explicit permission from apps that attempt to use it. It does not collect telemetry by default—check the installer options if you wish to opt into update checks.

Troubleshooting

If your device is not detected: try a different USB cable or port and ensure Bridge is running (look for the Bridge icon in your system tray/menu bar).
On browser errors: restart the browser and ensure no browser extensions block local connections.
If Bridge fails to install: run the installer as administrator / use the package manager for your distribution on Linux.

Security & best practices

Keep these safety guidelines in mind when using Bridge and your Trezor hardware wallet.

Always download Bridge from the official domain to avoid tampered installers.
Verify installer signatures or checksums when provided on the official site.
Never enter your recovery seed on a computer or browser — the seed is for offline backup only.
Confirm actions physically on your Trezor device before approving transactions or exchanges.
Keep Bridge and Trezor Suite up to date to receive security fixes and compatibility improvements.

Advanced: manual Bridge control

Power users can view Bridge status and logs via the system tray icon or the local status page (usually https://127.0.0.1:21325 when Bridge is running). Use logs for debugging only — avoid sharing logs that contain sensitive device identifiers.

Compatibility & versions

Bridge is maintained to support the most common OS versions. If you run an unconventional environment, check the release notes for supported platforms and known issues.

FAQ

Do I need Bridge if I use Trezor Suite desktop?

Desktop Trezor Suite often uses native drivers and may not require Bridge, but Bridge ensures broader browser compatibility and smoother device detection in many setups.

Is Bridge safe to run?

Yes — Bridge runs locally and facilitates secure USB communication. The most important protections are installing only official releases and confirming all operations on your Trezor device.

How do I uninstall Bridge?

Use your operating system’s usual uninstall mechanism (Add/Remove Programs on Windows, Applications on macOS, package manager removal on Linux). Restart your machine after uninstalling for best results.
