Trezor Bridge is an essential software tool that enables communication between your Trezor hardware wallet and your computer. Without it, your device cannot connect properly to Trezor Suite — the official desktop and web interface for managing your cryptocurrencies. This guide will walk you through everything you need to know about installing, using, and troubleshooting Trezor Bridge securely.
Trezor Bridge is a background service developed by SatoshiLabs, designed to facilitate secure data exchange between your hardware wallet and your browser or desktop app. Essentially, it acts as a communication layer that ensures commands and messages from Trezor Suite reach your physical device safely and efficiently. It replaces the need for browser plugins, offering better compatibility and improved security.
If you’re setting up your Trezor for the first time or logging into your wallet via trezor.io/start, you’ll be prompted to install Trezor Bridge. This software ensures that your browser or Trezor Suite recognizes your connected hardware wallet. Without it, the system won’t detect your Trezor device, making it impossible to perform transactions or access your portfolio.
Installing Trezor Bridge is quick and straightforward. Follow these steps to ensure a safe installation:

Technically, Trezor Bridge operates as a local HTTP server running on your computer. It creates a secure communication channel between the hardware device and the Trezor Suite interface. Whenever you initiate an action — like logging in, verifying an address, or signing a transaction — the bridge transfers data between your device and the suite using encrypted protocols, ensuring no information leaks or interference from external software.
To verify that Trezor Bridge is correctly installed and functioning:
