Trezor Bridge

The secure connection tool that links your Trezor hardware wallet to your computer and Trezor Suite.

What Is Trezor Bridge?

Trezor Bridge is an official communication software developed by Trezor to connect your hardware wallet (Trezor Model One or Trezor Model T) with your computer or browser-based wallet interface. It acts as the secure “bridge” that allows your web browser and desktop applications to interact with your device safely.

Without Trezor Bridge, your computer would not be able to detect your hardware wallet or execute signed transactions. It ensures encrypted communication, protecting your private keys from exposure or unauthorized access.

Purpose and Importance

The purpose of Trezor Bridge is to make communication between your Trezor device and software applications smooth, reliable, and secure. Since browsers like Chrome, Firefox, and Edge restrict direct USB communication for security reasons, the Bridge provides a trusted intermediary channel.

Note: Always download Trezor Bridge only from the official website: trezor.io/bridge.

How Trezor Bridge Works

Trezor Bridge operates silently in the background as a local service on your computer. When you connect your Trezor device via USB, Bridge detects it and establishes a secure communication channel with applications like Trezor Suite or supported browser wallets.

The Bridge uses secure HTTPS and local host communication to prevent malicious software from intercepting or spoofing device connections. Every request from your browser or desktop app is validated by Trezor Bridge before being passed to your hardware device.

Installing Trezor Bridge

Installing Trezor Bridge is simple and essential before setting up your hardware wallet. Follow these steps:

Once installed, Trezor Bridge will automatically run in the background whenever your device is connected.

Verifying Installation

To confirm that Trezor Bridge is running correctly, connect your Trezor device and open Trezor Suite. If the software detects your wallet, your Bridge is installed and working.

On some systems, you may also verify by checking your computer’s running services or background processes for “Trezor Bridge.”

If you encounter a “No device detected” message, ensure that your Bridge is running and updated to the latest version.

Updating Trezor Bridge

Keeping Trezor Bridge updated ensures the best performance and compatibility with new browser and OS updates.

The Bridge auto-updates in most modern setups, but manual updates ensure compatibility with Trezor Suite upgrades.

Security Architecture

Trezor Bridge is built with a security-first approach. It never stores, transmits, or logs your private keys. All sensitive operations — including key generation, signing, and encryption — occur inside your Trezor hardware wallet.

This layered design minimizes potential attack surfaces and aligns with Trezor’s mission of open, auditable security.

Privacy and User Control

Unlike typical browser extensions, Trezor Bridge doesn’t track user behavior or collect analytics data. It runs locally and communicates only when your hardware wallet is actively connected. This makes it one of the most privacy-respecting components of the Trezor ecosystem.

You maintain full control over your assets — no third party, including Trezor, can access your private information.

Integration with Trezor Suite

Trezor Bridge works hand-in-hand with Trezor Suite, the official desktop and web app for managing cryptocurrencies. It enables features such as:

This seamless integration ensures a smooth and secure user experience across all supported devices.

Conclusion

Trezor Bridge is a vital component of the Trezor ecosystem, enabling secure communication between your hardware wallet and desktop applications. By acting as a protected intermediary, it allows you to use Trezor Suite and other compatible tools with confidence.

Always ensure you download the Bridge from the official site — trezor.io/bridge — and keep it updated for maximum security and performance.

With Trezor Bridge, your hardware wallet remains isolated from online threats, ensuring your cryptocurrencies are managed safely and efficiently.
