Trezor Bridge* — Secure Connection Layer for Your Hardware Wallet

Overview

Trezor Bridge is a lightweight background application that enables secure communication between your Trezor hardware wallet and supported web browsers or cryptocurrency applications. It replaces older browser extensions and ensures a stable, encrypted connection without exposing sensitive wallet data.

Instead of handling private keys or storing user information, Trezor Bridge simply acts as a communication bridge—allowing websites and apps to interact with your device safely while all critical operations remain inside the hardware wallet.

For full wallet management, you can also explore Trezor Suite, the official desktop and web application for Trezor devices.


How Trezor Bridge Works

Trezor Bridge runs quietly on your computer in the background. When you connect your Trezor device, it automatically detects requests from supported web applications and securely passes communication between:

All signing actions (like confirming transactions) are completed directly on the physical device, ensuring that private keys never leave the wallet.


Key Functions

1. Secure Communication Channel

Enables encrypted interaction between browser-based apps and your Trezor device.

2. Device Detection

Automatically recognizes connected Trezor hardware wallets without manual configuration.

3. Transaction Support

Helps process transaction requests while final confirmation always happens on the device screen.

4. Background Operation

Runs silently in the system tray or background services with minimal resource usage.


Why Trezor Bridge Matters

Without Trezor Bridge, modern browsers would not reliably communicate with hardware wallets due to security restrictions. It solves this by acting as a trusted local interface.
