Trezor Bridge — Secure Connectivity & Migration Guide

Trezor hardware wallets are widely recognized for their industry-leading security, keeping private keys offline and safe from malware or online attacks. However, to interact with desktop and web applications, secure connectivity is essential. This is provided by Trezor Bridge, a secure middleware that ensures seamless communication between your Trezor wallet and supported software platforms.

This guide provides an in-depth overview of Trezor Bridge, its installation, usage, and migration processes, ensuring users can manage cryptocurrencies safely and efficiently.

1. Introduction to Trezor Bridge

Trezor Bridge is a communication layer that connects Trezor hardware wallets to desktop applications, web wallets, and Trezor Suite. By encrypting commands and responses, it guarantees that sensitive information remains secure, allowing users to:

• View and manage cryptocurrency balances
• Send and receive digital assets safely
• Update wallet firmware securely
• Integrate with Web3 and third-party applications

Bridge replaces older connection methods, such as the Trezor Chrome extension, providing greater compatibility and security across modern platforms.

2. Importance of Trezor Bridge

Secure connectivity is vital for managing cryptocurrencies. Trezor Bridge provides:

• Encrypted Communication: Ensures all messages between the wallet and computer are protected.
• Device Recognition: Automatically detects Trezor devices connected via USB.
• Cross-Platform Compatibility: Supports Windows, macOS, Linux, and modern browsers.
• Firmware Updates: Facilitates secure application of official firmware updates.
• Developer APIs: Allows integration of Trezor hardware into custom applications and blockchain projects.

3. Installing Trezor Bridge

Follow these steps to install Trezor Bridge:

1. Visit the official Trezor Bridge page.
2. Select the installer compatible with your operating system (Windows, macOS, Linux).
3. Download and run the installer.
4. Follow on-screen instructions to complete installation.
5. Restart your browser or desktop application to initialize Bridge.

Once installed, Trezor Bridge runs in the background, providing secure communication whenever a Trezor device is connected.

4. System Requirements

Trezor Bridge is compatible with most modern systems and browsers:

• Operating Systems: Windows 10+, macOS 10.15+, Linux distributions
• Browsers: Chrome, Firefox, Edge, and other WebUSB-enabled browsers
• Hardware Wallets: Trezor One or Model T
• Internet: Required for firmware updates and blockchain synchronization

5. How Trezor Bridge Works

Trezor Bridge functions as a secure intermediary, enabling encrypted communication between the hardware wallet and software interface:

1. User initiates an action in Trezor Suite or a web wallet.
2. Bridge encrypts the request and sends it to the Trezor device via USB.
3. The hardware wallet verifies the request and prompts the user for confirmation.
4. Signed transactions or requested data are sent back through Bridge to the application.

This ensures private keys never leave the hardware device, keeping your cryptocurrency safe from malware and phishing attacks.

6. Security Features of Trezor Bridge

• Encrypted communication ensures data cannot be intercepted.
• Private keys remain isolated on the hardware device.
• All transactions must be confirmed on-device.
• Bridge supports secure firmware updates directly from Trezor.
• Access control prevents unauthorized software from communicating with the wallet.

7. Migration Guide

If you are transitioning from an older Trezor setup or migrating to a new device, Trezor Bridge ensures a smooth and secure process. Follow these steps:

Step 1: Backup Recovery Seed

Before migration, ensure your recovery seed is securely backed up. This seed allows you to restore your wallet on any Trezor device.

Step 2: Install Trezor Bridge

Install the latest Trezor Bridge on your system to ensure compatibility with both old and new devices.

Step 3: Connect Your Old Device

Open Trezor Suite and connect your old hardware wallet. Ensure Bridge is running to facilitate secure communication.

Step 4: Verify Accounts and Assets

Check all cryptocurrencies and tokens stored on the device. Take note of account balances and transaction history.

Step 5: Connect New Device

Connect your new Trezor device and follow the Suite prompts to restore your wallet using the backup recovery seed.

Step 6: Verify Assets on New Device

After restoration, confirm all balances and tokens are correctly displayed. Test sending a small transaction to ensure proper functionality.

Step 7: Update Firmware

Use Trezor Bridge to securely update firmware on the new device, ensuring you have the latest security features and bug fixes.

8. Using Trezor Bridge with Trezor Suite

Bridge enables seamless integration with Trezor Suite, allowing you to:

• Monitor portfolio and account balances
• Send and receive cryptocurrencies safely
• Apply firmware updates securely
• Manage multiple wallets and tokens
• Access advanced settings such as passphrases and hidden wallets

9. Troubleshooting Common Issues

• Device Not Detected: Ensure Bridge is installed and running, reconnect the device, or try a different USB port.
• Browser Connection Failures: Restart the browser, ensure WebUSB is supported, and disable conflicting extensions.
• Outdated Bridge Version: Download the latest version from Trezor’s official website.
• Firmware Update Failures: Check internet connection and confirm the device screen during updates.

10. Privacy and Security Best Practices
