Trezor Bridge

Secure Communication Between Your Browser and Trezor Device

Overview of Trezor Bridge

Trezor Bridge is a background communication service that enables smooth and secure interaction between your Trezor hardware wallet and supported web applications. It replaces older browser plugin systems with a more reliable and secure architecture designed for modern operating systems.

When you connect your Trezor device, Bridge acts as a translator between your browser and the hardware wallet, ensuring commands and confirmations are transmitted correctly without exposing private keys or sensitive data.

Why Trezor Bridge is Important

  • Allows browsers to recognize your Trezor hardware wallet.
  • Enables transaction signing through secure device confirmation.
  • Maintains encrypted communication channels.
  • Works quietly in the background without affecting system performance.
Trezor Bridge never stores private keys or recovery phrases. All critical operations occur inside the hardware wallet itself.

Installation Guide

Step 1 — Download

Obtain the installation package compatible with your operating system (Windows, macOS, or Linux).

Step 2 — Install

Run the installer and follow system prompts. Administrative permission may be required.

Step 3 — Restart Browser

Close and reopen your browser after installation so the Bridge service can be detected.

Step 4 — Connect Device

Attach your Trezor hardware wallet via USB and open a supported wallet interface.

How It Works Behind the Scenes

Trezor Bridge creates a local communication channel between your computer and browser. When a web wallet sends a request (like signing a transaction), Bridge forwards that request to your device. You then verify and approve the action directly on the Trezor screen.

This structure ensures sensitive cryptographic operations never leave the hardware wallet, protecting you from browser-based attacks and malicious scripts.

Security Practices

  • Install Bridge only from official sources.
  • Always verify transaction details on the device display.
  • Keep your firmware and wallet interface updated.
  • Do not share your recovery phrase under any circumstances.

Troubleshooting Connection Issues

  • Ensure the USB cable supports data transfer.
  • Restart both your browser and computer.
  • Check whether Bridge is running in the background services.
  • Try a different USB port.
