How Trezor Bridge Works
Trezor Bridge establishes a secure communication channel between web applications and your Trezor device. When you connect your Trezor to your computer, the Bridge service detects the device and prepares it for interaction with supported web interfaces.
The process involves:
- Detecting when a Trezor device is connected to your computer
- Establishing encrypted communication with web applications
- Translating browser requests into commands the hardware wallet understands
- Returning signed transaction data to the web application
All cryptographic operations, including private key usage, occur exclusively on your Trezor device - never on your computer or in the browser.
