What is Trezor Bridge?
Trezor Bridge is a background service that facilitates secure communication between your Trezor hardware wallet and web browsers. It acts as a bridge, enabling your Trezor device to interact with web-based cryptocurrency applications and wallet interfaces without compromising security.
Unlike browser extensions, Trezor Bridge runs as a standalone application in the background, providing a more stable and secure connection to your Trezor device while you manage your cryptocurrencies.

How Trezor Bridge Works
Trezor Bridge establishes a secure local connection between your computer and Trezor device. When you access a Trezor-compatible web application, the service detects this and facilitates the communication protocol needed for your hardware wallet to interact with the web interface.
Communication Flow
The process involves several security layers:
- Your Trezor device remains physically disconnected from the internet at all times
- Trezor Bridge creates a secure local channel between the device and browser
- All sensitive operations requiring private keys are performed on the Trezor device itself
- Only verified transaction data is transmitted between components
Security Architecture
Trezor Bridge implements multiple security measures to protect your assets:
- Local-only communication prevents exposure to network-based attacks
- Cryptographic verification ensures data integrity
- Automatic detection of Trezor devices with user confirmation
- Isolation of sensitive operations within the hardware wallet
