Trézór Bridge® The (official) wallet | Trézor®

Introduction to Trézór Bridge®

Trézór Bridge® is the official communication interface between the Trezor® hardware wallet and your web browser. It acts as the essential connection that enables browser-based applications and web wallets to interact securely with your Trezor® device, ensuring transactions can be signed without compromising private keys.

Trezor® was created by SatoshiLabs, a pioneering force in crypto security. To maintain secure browser integrations, Trézór Bridge® replaces older browser plugins and ensures compatibility with modern browsers while offering superior speed, stability, and security.

What Is Trézór Bridge®?

Trézór Bridge® is a small background software utility that runs locally on your computer. Its function is to detect the Trezor® device when it is connected via USB and to establish secure communication between the wallet and the Trezor Suite interface or supported third-party wallets.

Unlike browser extensions, Trézór Bridge® doesn’t rely on outdated plugin architecture. It is constantly updated, open-source, and built to support the highest levels of security for crypto transactions on supported web platforms.

Why Trézór Bridge® Is Important

The success of hardware wallets lies in their ability to store private keys offline. However, to execute a transaction, users need a secure method of signing that transaction using their hardware wallet—this is where Trézór Bridge® plays a critical role.

Key Benefits of Trézór Bridge®:

• Secure Communication: All transaction data is securely sent from your browser to the hardware wallet for signing.
• No Browser Extensions Needed: Works without relying on third-party browser plugins.
• Automatic Device Detection: Instantly recognizes when a Trezor® wallet is plugged into your system.
• Lightweight and Efficient: Runs quietly in the background without interrupting system performance.
• Supports Multiple Wallet Interfaces: Enables connectivity with Trezor Suite as well as compatible third-party web wallets and dApps.

Supported Platforms and Browsers

Trézór Bridge® is compatible with all major operating systems and works seamlessly on:

• Windows 10 and 11
• macOS Monterey and newer
• Linux distributions including Ubuntu and Fedora

It is optimized for use with popular browsers:

• Google Chrome
• Mozilla Firefox
• Microsoft Edge
• Brave Browser

Note: Safari is not supported due to limitations in USB access through the browser.

Downloading and Installing Trézór Bridge®

To begin using Trézór Bridge®, follow these steps:

Step 1: Visit the Official Trezor Site

Navigate to the official site: https://trezor.io/start This ensures you are downloading the authentic software directly from Trezor’s developers.

Step 2: Install Trézór Bridge®

The Trezor site will detect if Bridge is not yet installed and prompt you to download it. Select your operating system and follow the on-screen installation instructions.

After installation, the Bridge application will run silently in the background, launching on system start.

Step 3: Connect Your Trezor®

Plug in your Trezor® Model One or Trezor® Model T using the provided USB cable. Your browser should automatically detect the device, provided Trézór Bridge® is installed and active.

How Trézór Bridge® Works with Trezor Suite

Although Trezor Suite Desktop (the standalone application) does not require Bridge, if you use the web version of Trezor Suite, Trézór Bridge® becomes essential.

Use Cases:

• Web-based wallet management
• Browser-based dApp integration
• Token swaps or DeFi transactions via third-party dApps
• Real-time crypto transaction approvals directly in browser

Bridge acts as the middle layer, ensuring that all browser interactions are passed to your hardware wallet safely and privately, without risking the exposure of sensitive data.

Troubleshooting and Common Issues

Despite its simplicity, users may occasionally run into issues with Trézór Bridge®. Below are common problems and how to fix them:

1. Bridge Not Detected

• Solution: Make sure the Bridge is running. You can restart it or reinstall the software from the official site.

2. Browser Not Recognizing Device

• Solution: Ensure you are using a compatible browser with the latest updates. Clear cache or try another supported browser.

3. Conflicts with Trezor Suite Desktop

• Solution: Bridge is not required for the standalone desktop app. If both are used simultaneously, close the desktop app when working in a browser environment.

Bridge vs. WebUSB

In some newer browser builds, WebUSB is offered as an alternative to Bridge. While WebUSB allows browser-native USB communication without the need for additional software, Trézór Bridge® remains more consistent and broadly compatible across systems and browser environments.

Bridge is generally more stable, especially on enterprise networks or older OS versions, and continues to be recommended for most users accessing Trezor® via browsers.

Security Measures in Trézór Bridge®

Security is a top priority for any Trezor® component. Trézór Bridge® maintains high standards through:

• Code Signing: All official binaries are signed for integrity and trust.
• Open Source Code: Auditable by third parties and community contributors.
• Encrypted Communication: All communication between browser and device is protected from external threats.
• Automatic Updates: Ensures latest features and patches are applied.

Bridge does not store any user data. Its only role is to relay signed transaction requests between your browser and your device.

Updating Trézór Bridge®

Staying updated ensures compatibility with new coins, browser upgrades, and Trezor firmware releases.

To update Bridge:

1. Visit trezor.io/start
2. If a new version is available, you will be prompted to update
3. Download the installer and follow the steps—no need to uninstall the previous version

Always restart your browser after updating Bridge to ensure it loads properly.

Summary

Trézór Bridge® is a foundational component of the Trezor ecosystem, serving as the secure gateway between your browser and your Trezor® hardware wallet. Whether you're using the web version of Trezor Suite, managing assets on supported third-party dApps, or signing secure transactions, Bridge ensures a seamless and private experience.

With full support for all major operating systems and browsers, combined with the transparency of open-source development, Trézór Bridge® is a reliable and secure option for anyone who values complete control over their cryptocurrency wallet.
