Trezor Bridge — Seamless Connection Between Your Browser and Hardware Wallet
Trezor Bridge is a lightweight communication tool that enables your web browser to interact securely with your Trezor hardware wallet. It acts as a background service that ensures stable, encrypted connectivity between Trezor Suite (web version) and your device.
Without Trezor Bridge, some browsers cannot properly detect or communicate with the hardware wallet, making it an essential component for a smooth user experience.
What is Trezor Bridge?
Trezor Bridge is a software utility developed by SatoshiLabs to facilitate secure communication between:
Your Trezor hardware wallet
Your web browser (Chrome, Firefox, Edge, etc.)
The Trezor Suite web application
It runs quietly in the background and ensures that every request between your device and browser is properly encrypted and verified.
