Why Trezor Bridge Exists
Modern browsers frequently restrict direct USB communication to prevent potential misuse. While this enhances security in general, it can block legitimate interactions with hardware wallets. Trezor Bridge was designed as a lightweight background service to overcome these limitations safely.
When installed, it runs silently on your computer and handles secure data transfer between your browser and the connected Trezor device. This approach allows Suite, the Trezor web wallet, or third-party integrations to detect, initialize, and communicate with your hardware wallet without exposing private data.
