Trezor Bridge

Trezor Bridge is a secure communication layer that connects your Trezor hardware wallet to supported desktop browsers. It ensures reliable, private, and trusted interaction between your device and web-based wallet interfaces.

What Is Trezor Bridge?

Trezor Bridge is background software that allows your browser to recognize and communicate with your Trezor hardware wallet. Modern browsers restrict direct USB access for security reasons, and Trezor Bridge solves this by acting as a trusted intermediary.

It runs silently in the background and activates only when a supported wallet interface requests access to your connected Trezor device.

Why Trezor Bridge Is Important

Secure Communication

All communication between your browser and Trezor device is routed through a verified local service, minimizing exposure to malicious scripts.

Browser Compatibility

Ensures smooth connectivity across major browsers that do not natively support hardware wallet USB communication.

Seamless User Experience

Automatically detects your device and maintains a stable connection without manual configuration.

How Trezor Bridge Works

When you connect your Trezor hardware wallet to your computer, Trezor Bridge listens locally for approved requests from supported wallet interfaces.

  • Your private keys always remain inside the Trezor device
  • No sensitive data is transmitted to external servers
  • All actions require physical confirmation on the device
Security Note: Trezor Bridge never asks for recovery phrases, PINs, or passwords.

Installation & Setup

  1. Disconnect your Trezor device from the computer before installation.
  2. Download and install Trezor Bridge from an official source only.
  3. Restart your browser after installation is complete.
  4. Reconnect your Trezor device and open a supported wallet interface.

Once installed, Trezor Bridge runs automatically in the background and requires no further action.

Common Questions

Do I need Trezor Bridge on every computer?

Yes. Trezor Bridge must be installed on each desktop computer where you plan to use your Trezor device.

Is Trezor Bridge safe to keep running?

Yes. It remains inactive unless a supported interface initiates a connection request.

Can I remove it later?

Reliable. Secure. Invisible.

Trezor Bridge works quietly in the background so you can focus on managing your digital assets with confidence and peace of mind.

Reminder: Always use official software and never share your recovery seed.
