Trezor Bridge

The secure communication layer that connects your Trezor hardware wallet to supported browsers and applications — enabling safe crypto transactions without exposing private keys.

What is Trezor Bridge?

Trezor Bridge is a lightweight background service that enables communication between your Trezor hardware wallet and your web browser. It replaces older browser plugins and ensures a secure and seamless connection when using web-based wallet interfaces.

Without Trezor Bridge, browsers cannot directly interact with USB hardware wallets. The Bridge acts as a translator between the device and web applications, allowing secure transaction signing while maintaining complete private key isolation.

This software is automatically installed when required and runs quietly in the background to maintain encrypted communication between the hardware device and your system.

Why Trezor Bridge is Important

Secure Communication

Creates encrypted local connection between device and browser.

No Browser Extensions

Eliminates dependency on potentially vulnerable plugins.

Automatic Detection

Detects connected Trezor device instantly.

Cross-Platform Support

Available for Windows, macOS, and Linux.

How Trezor Bridge Works

Step 1: User connects Trezor device via USB.
Step 2: Browser detects request from wallet interface.
Step 3: Trezor Bridge establishes local encrypted channel.
Step 4: Transaction data sent to device for signing.
Step 5: User confirms on hardware screen.
Step 6: Signed transaction returned securely to browser.

This entire process ensures private keys never leave the hardware wallet.

Installation Guide

  1. Visit the official Trezor website.
  2. Download Trezor Bridge for your operating system.
  3. Run the installer and complete setup.
  4. Restart your browser if necessary.
  5. Reconnect your Trezor device.

Security Architecture

  • Local-only communication channel.
  • No cloud-based key transmission.
  • Mandatory on-device transaction confirmation.
  • Open-source code transparency.
  • Firmware verification compatibility.

Trezor Bridge ensures that even if a malicious website attempts interference, transactions cannot proceed without physical confirmation on the device.

Troubleshooting Common Issues

Keeping your system updated ensures smooth communication between wallet and browser.
