Introduction to Trezor Bridge
Trezor Bridge is a vital software component developed by Trezor that enables secure communication between your Trezor hardware wallet and web applications. It ensures that users can interact safely with their crypto assets without compromising security.
Why Trezor Bridge is Important
Modern web browsers do not allow direct communication with USB devices due to security restrictions. Trezor Bridge acts as a secure intermediary, allowing your browser to communicate with the Trezor device safely.
Key Benefits
- Encrypted communication between device and applications.
- Compatibility with all major browsers.
- Easy installation and updates.
- Ensures maximum security while handling crypto transactions.
How Trezor Bridge Works
Trezor Bridge uses a local server that runs on your computer. When you connect your Trezor device, the browser communicates with this local server using secure protocols. This ensures that sensitive data, such as private keys, never leaves the device.
Technical Architecture
The Trezor Bridge architecture consists of three layers:
- Device Layer: The hardware wallet storing private keys securely.
- Bridge Layer: Local communication server that handles requests from web apps.
- Application Layer: Web or desktop applications that request operations from the device.
Security Features
- End-to-end encryption for all communications.
- Device authentication to prevent unauthorized access.
- Automatic updates to patch security vulnerabilities.
