Trezor Bridge

Secure Connection Between Your Trezor and the Web

Introduction

Trezor Bridge is an essential background service that enables secure communication between your Trezor hardware wallet and web-based applications, such as Trezor Suite and supported third‑party wallets. It acts as a trusted connector, allowing your browser to recognize and interact with your Trezor device safely and reliably.

For users who manage cryptocurrencies through a hardware wallet, Trezor Bridge ensures that sensitive operations—like signing transactions—happen securely on the device itself, not on the computer or browser.

What Is Trezor Bridge?

Trezor Bridge is a lightweight software component installed on your computer. Its main role is to:

• Detect your connected Trezor device
• Enable encrypted communication between the device and your browser
• Replace older browser plugins with a more secure, modern solution

Once installed, Trezor Bridge runs silently in the background and automatically handles communication whenever you access a compatible wallet interface.

Why Trezor Bridge Is Important

Without Trezor Bridge, your browser would not be able to communicate with your hardware wallet. This connection layer is critical for maintaining both usability and security.

Key Benefits

• Enhanced Security – Private keys never leave your Trezor device
• Seamless Browser Support – Works with Chrome, Firefox, Edge, and more
• Automatic Updates – Ensures compatibility with new wallet features
• Cross‑Platform – Available for Windows, macOS, and Linux

By separating wallet communication from browser extensions, Trezor Bridge reduces the attack surface and improves overall system stability.

How Trezor Bridge Works

The workflow of Trezor Bridge is simple and secure:

1. You connect your Trezor device to your computer via USB
2. Trezor Bridge detects the device automatically
3. Your browser sends requests through Trezor Bridge
4. The Trezor device confirms and signs transactions internally
5. Only signed data is returned to the browser

At no point are your recovery seed or private keys exposed to the internet.
