Installation & Setup
Installing Trezor Bridge is simple. Download the official installer for your operating system from the Trezor website, run the installer, and follow the prompts. Once installed, connect your Trezor device and grant permission to access it. The installation automatically registers required services or udev rules to ensure proper communication. https://trezor.io/bridge

Once Bridge is running, your applications will automatically detect the Trezor device. When performing a transaction, Bridge relays the signing request to the hardware wallet, which displays the transaction details for user confirmation. Only after the user approves the transaction will the signed data be returned to the app. This ensures that sensitive operations are never exposed to the host system. https://trezor.io/bridge

Security & Privacy
Trezor Bridge enforces strong security and privacy practices. It never stores private keys, seed phrases, or sensitive credentials. All communications occur locally via loopback interfaces. The device verifies all critical operations with on-screen confirmations. This design ensures that even if the host computer is compromised, attackers cannot sign transactions or access your keys. https://trezor.io/bridge
