Trezor® Bridge – Secure Way to Your Hardware Wallet®

1. What is Trezor Bridge?

Trezor Bridge is an essential software component that securely connects your Trezor hardware wallet to your computer or browser. Unlike browser extensions, Bridge creates a direct, encrypted communication channel between your device and Trezor Suite, ensuring your private keys never leave the hardware.

• Secure transaction signing
• Automatic detection of device features
• Enhanced compatibility across operating systems

3. System requirements

Before installing Trezor Bridge, ensure your system meets the following minimum requirements:

• Operating System: Windows 10 or higher, macOS 10.14+, Linux distributions
• USB port for Nano devices or Bluetooth for Trezor Model T (if applicable)
• Web browser: Chrome, Firefox, or Brave (latest versions)
• Administrator rights for installation

4. Download and install Trezor Bridge
