Trezor Bridge is a small software program that acts as a secure communication layer between your Trezor hardware wallet and your computer’s web browser or desktop apps like Trezor Suite. It ensures your computer can safely interact with the hardware wallet so you can manage your cryptocurrency.
Here’s a detailed breakdown:
1. Purpose of Trezor Bridge
Your computer cannot communicate with the Trezor hardware wallet directly through a browser without a bridge. Trezor Bridge acts like a translator, passing information back and forth between your device and the apps you use, while keeping your private keys safely offline on the Trezor.
2. How It Works
Installation: You download and install Trezor Bridge from the official Trezor website.
Connection: When you plug in your Trezor device, the Bridge automatically detects it and allows your browser or Trezor Suite to connect.
Communication: The Bridge encrypts messages between your Trezor device and your computer, ensuring sensitive data never leaks to the internet.
3. Key Benefits
Security – Keeps all private keys offline and ensures transactions are signed on the Trezor device itself.
Browser Compatibility – Works with modern browsers like Chrome, Firefox, and Edge to enable web-based interactions with your wallet.
Reliable Updates – Trezor Bridge is updated regularly to support new devices, improve performance, and fix security vulnerabilities.
4. Using Trezor Bridge
When you first open Trezor Suite or access a supported website like Trezor.io/start, the application will prompt you to install Trezor Bridge if it’s not already installed.
After installation, simply connect your Trezor device via USB. Trezor Bridge handles all communication automatically.
You don’t need to open the Bridge manually—it runs in the background and ensures a seamless connection between your wallet and apps.
5. Important Notes
Only download Trezor Bridge from the official Trezor website to avoid phishing or malware.
Trezor Bridge is required for most web-based wallet interactions; without it, your Trezor device won’t be detected by browsers.
Always keep Trezor Bridge up to date to ensure compatibility and security with the latest hardware wallets and firmware.
