Trezor Bridge is a local connector that enables secure communications between your Trezor hardware wallet and desktop/web wallets. Install the official Bridge package for your operating system, start the Bridge service, then plug in your Trezor device. When prompted by your wallet application, confirm the connection on-device and approve any actions directly on the hardware — this ensures your private keys never leave the device. Bridge reduces friction for users and developers by providing a stable, well-documented API and privacy-focused defaults. If you encounter any issues, check the Bridge UI for status, consult the troubleshooting section above, or reach out to the support center for guided help.
