Secure USB communication and trusted device pairing
Trezor Bridge is the official secure gateway between your browser or apps and your Trezor hardware device. Trezor Bridge provides a reliable, cross-platform bridge for secure USB connections, easy pairing, and consistent device discovery.
As the name suggests, Trezor Bridge – The Secure Gateway to Your Hardware acts as a trusted intermediary that handles device communication, verification, and secure transport. It ensures messages between your software and hardware are routed safely, minimizes friction when switching platforms, and simplifies the setup flow for new users. Whether you're using Windows, macOS, or Linux, Trezor Bridge detects your Trezor device and maintains an encrypted channel for signing and device management.
How Trezor Bridge works
Trezor Bridge runs a small local service that listens for requests from web apps and desktop applications. When a web app requests to communicate with your Trezor device, Bridge facilitates a secure channel and prompts you on the device to confirm actions. This model keeps sensitive key material inside the hardware wallet while allowing modern apps to interact safely.
Best practices
- Always download Trezor Bridge from the official site.
- Keep your Bridge installation and firmware up to date.
- Verify installer checksums and release signatures when possible.
- Only confirm transactions you recognize on your device screen.
