Overview — What is Trezor Bridge?
Trezor Bridge is a lightweight local helper that enables secure communication between your Trezor hardware wallet and desktop or web applications (such as Trezor Suite). It avoids direct browser USB limitations by providing a trusted, local transport layer — signatures and private keys remain on the device. 🔒
Why it exists: modern browsers restrict direct device access for security. Bridge provides a controlled local interface so web apps can request signing operations that still require physical confirmation on the Trezor device.
