Trézor Bridge® | Introducing the New Trezor® App

Trezor Bridge – Secure Communication Between Device and Computer

Trezor Bridge is the official communication software developed by Trezor to connect your Trezor hardware wallet (such as the Trezor Model T or Trezor One) to your computer or web browser. It acts as a secure intermediary, allowing the Trezor device to interact with applications like Trezor Suite or supported web wallets without ever exposing your private keys.

Trezor Bridge ensures that all communications between your hardware wallet and your computer are encrypted and safe, providing a seamless and secure interface for managing cryptocurrencies.

What Is Trezor Bridge?

Trezor Bridge is software installed on your computer that enables your browser or desktop app to detect and interact with your Trezor hardware wallet. It eliminates the need for browser plugins and provides cross-platform compatibility, allowing Windows, macOS, and Linux users to securely manage their digital assets.

Trezor Bridge works in the background to:

• Facilitate encrypted communication between Trezor devices and your computer
• Enable secure transactions and account management
• Support Trezor Suite and web-based wallet interfaces
• Verify firmware updates and app installations

Key Features of Trezor Bridge

1. Secure Device Communication

Trezor Bridge ensures that your hardware wallet can safely communicate with your computer or browser. The bridge encrypts all messages, protecting sensitive data such as transaction details or device commands from interception.

2. Cross-Platform Compatibility

Trezor Bridge works on:

• Windows (7, 8, 10, 11)
• macOS
• Linux

It supports all major browsers, including Chrome, Firefox, and Edge, providing a consistent experience regardless of your operating system.

3. No Browser Extensions Required

Previously, connecting a Trezor device required a browser plugin. With Trezor Bridge:

• Browser plugins are no longer necessary
• Security risks associated with plugins are reduced
• Updates are easier to manage and verify

4. Seamless Integration with Trezor Suite

Trezor Bridge allows Trezor Suite to detect your device, enabling:

• Account setup and management
• Portfolio monitoring
• Sending and receiving cryptocurrencies
• Firmware updates and device configuration

All these actions require device confirmation, keeping private keys offline.

5. Firmware and App Verification

When updating your Trezor hardware wallet, Trezor Bridge ensures that firmware files are verified and properly transmitted to your device. This protects against corrupted or malicious firmware and ensures the integrity of your wallet.

Installing Trezor Bridge

1. Visit Trezor.io/Start.
2. Download the version compatible with your operating system.
3. Install Trezor Bridge and restart your browser or computer.
4. Connect your Trezor device and launch Trezor Suite or a supported web wallet.

After installation, Trezor Bridge runs in the background, enabling your device to communicate securely with applications.

Using Trezor Bridge for Secure Transactions

When you send or receive cryptocurrency:

1. Trezor Bridge transmits transaction data to the hardware wallet.
2. The hardware wallet signs the transaction internally.
3. Trezor Bridge sends the signed transaction back to the application for broadcasting.

At no point does your private key leave the Trezor device. This offline signing mechanism ensures that your assets remain protected even if your computer is compromised.

Security Advantages

• Encrypted Communication: All data between your device and computer is secure.
• Offline Key Protection: Private keys never leave the hardware wallet.
• Reduced Attack Surface: No browser plugin vulnerabilities are required.
• Verified Updates: Firmware and app updates are verified before installation.

Trezor Bridge significantly enhances the security of cryptocurrency management by ensuring that sensitive operations are executed safely.

Troubleshooting Trezor Bridge

Common issues include:

• Device Not Detected: Ensure the USB cable supports data transfer, restart your computer, and check that the latest version of Trezor Bridge is installed.
• Browser Communication Problems: Close and reopen the browser, or clear cache.
• Firmware Update Failures: Verify that Trezor Bridge is up-to-date and the device is properly connected.

Following these steps usually resolves connection or communication issues.

Trezor Bridge vs Other Connection Methods

Trezor Bridge provides a safer and more versatile method to connect hardware wallets to computers compared to older plugin-based solutions.

Best Practices

• Always download Trezor Bridge from the official Trezor site.
• Keep the software updated for compatibility and security.
• Confirm every transaction or firmware update on your Trezor device.
• Use Trezor Suite for managing assets rather than unverified third-party apps.

Final Thoughts

Trezor Bridge is an essential component for anyone using a Trezor hardware wallet. It ensures secure, encrypted communication between your device and computer or browser, enabling safe cryptocurrency management, transaction signing, and firmware updates.

By combining Trezor Bridge with Trezor Suite, users gain a powerful, secure, and user-friendly platform for controlling their crypto assets while keeping private keys offline and protected.
