About Trezor Bridge
Trezor Bridge is an essential component that enables communication between your Trezor hardware wallet and web-based interfaces like Trezor Suite. It operates as a background service on your computer, providing a secure channel that keeps your cryptocurrency transactions protected at all times.
Unlike browser extensions that might have vulnerabilities, Trezor Bridge runs independently of your browser, maintaining the high security standards that Trezor is known for. It automatically detects when you connect your Trezor device and establishes an encrypted connection without exposing your sensitive data.
Security First
Always download Trezor Bridge exclusively from the official Trezor website (trezor.io). Third-party sources may distribute modified versions that could compromise your cryptocurrency security. Verify the authenticity of your download to ensure you're using genuine Trezor software.
Key Features
Military-Grade Encryption
All communication between your Trezor and browser is encrypted using advanced cryptographic protocols, ensuring your private keys never leave your hardware wallet.
Automatic Updates
Trezor Bridge silently updates itself in the background, ensuring you always have the latest security enhancements without any user intervention required.
Universal Compatibility
Works seamlessly across Windows, macOS, and Linux systems, supporting all major browsers including Chrome, Firefox, Edge, and Brave.
How It Works
The technical architecture of Trezor Bridge is designed with uncompromising security:
When you connect your Trezor device, Bridge detects it through USB protocols and creates a local web server that listens for communication from your browser. This server acts as a secure mediator, translating browser requests into USB commands that your Trezor understands, and vice versa.
This sophisticated architecture ensures multiple layers of protection:
- Private keys remain exclusively on your Trezor device
- All communication is end-to-end encrypted
- Malicious websites cannot directly access your hardware wallet
- Each transaction requires physical confirmation on the device
- No sensitive data is stored on your computer
