Trezor Bridge — Secure Connection for Your Trezor Wallet

Trezor hardware wallets provide industry-leading security for cryptocurrency management by keeping private keys offline and protected. However, to interact with desktop and web applications safely, a secure communication layer is essential. This is where Trezor Bridge comes in — a reliable software solution that connects your Trezor wallet to applications while maintaining the highest security standards.

Trezor Bridge ensures that commands, transactions, and sensitive data are encrypted and transmitted safely between your hardware wallet and compatible software, providing seamless, secure access to your digital assets.

1. Introduction to Trezor Bridge

Trezor Bridge is a software application installed on your computer that acts as a communication layer between Trezor hardware wallets and supported applications such as Trezor Suite, web wallets, and third-party platforms. By encrypting communication and verifying requests, Trezor Bridge ensures that private keys never leave the device and that all transactions are authorized by the user.

It replaces older solutions such as the Trezor Chrome Extension, offering better cross-platform support, enhanced security, and compatibility with modern web browsers.

2. Why Trezor Bridge is Important

Secure connectivity is crucial for cryptocurrency management. Trezor Bridge provides several key benefits:

• Encrypted Communication: Protects data sent between your wallet and applications.
• Device Detection: Automatically recognizes Trezor wallets connected via USB.
• Cross-Platform Support: Works on Windows, macOS, Linux, and WebUSB-compatible browsers.
• Firmware Updates: Facilitates safe updates of your Trezor device firmware.
• Developer Access: Provides APIs for integrating Trezor devices with custom applications.

3. Installing Trezor Bridge

Installing Trezor Bridge is straightforward:

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

Once installed, Trezor Bridge runs in the background and facilitates secure communication whenever your Trezor device is connected.

4. System Requirements

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

5. How Trezor Bridge Works

Trezor Bridge acts as a secure intermediary between your hardware wallet and software:

1. User initiates a transaction or action in Trezor Suite or a compatible web wallet.
2. Bridge encrypts the request and transmits it via USB to the Trezor device.
3. The hardware wallet verifies the request, and the user approves it on the device screen.
4. Signed transactions or requested data are sent back through Bridge to the application.

This ensures that private keys remain offline while allowing smooth access to your digital assets.

6. Security Features

• Encrypted communication prevents data interception.
• Private keys remain isolated on the Trezor device.
• Transactions must be confirmed on the device itself.
• Firmware updates are performed securely via Bridge.
• Only authorized applications can interact with the wallet.

8. Migration and Device Replacement

When transitioning to a new Trezor device, Bridge ensures a secure migration process:

1. Back up your recovery seed from the old device.
2. Install the latest version of Trezor Bridge.
3. Connect your old device to Trezor Suite to verify balances and accounts.
4. Connect the new device and restore it using the recovery seed.
5. Confirm all assets and accounts are restored correctly.
6. Apply firmware updates to the new device through Bridge.
