A concise presentation layout describing purpose, security model, installation, and best practices for Trezor Bridge.
Trezor Bridge is a lightweight local service that securely connects your Trezor hardware wallet to desktop applications and web interfaces. Acting as a bridge between the browser and the device, it facilitates encrypted transport and device discovery while keeping keys isolated on the hardware.
Features include secure USB communication, automatic device detection, signed firmware checks, and a simple installer for major operating systems. Bridge minimizes attack surface by providing a single trusted endpoint and by strictly limiting the scope of requests that reach the device.
All sensitive operations — private key storage, signing, and PIN handling — happen on the Trezor device. Bridge operates as a transport layer only; it never exports keys. Communications are authenticated and sandboxed, and Bridge verifies firmware signatures before allowing sensitive commands.
Installation is straightforward: download the official Bridge installer, run the package for your OS, and follow on-screen prompts. After installation, open your preferred wallet or browser app and allow Bridge to provide the device connection. Keep Bridge updated to receive security patches.
Always download Bridge from the official Trezor website, verify checksums where available, keep firmware and Bridge updated, and use a clean, trusted machine for large transfers. Never share your recovery seed — Bridge will never request it.
If the device is not detected, confirm USB cable integrity, restart Bridge, and check OS permissions for USB access. Reinstall Bridge if needed and consult official documentation for logs and support steps.
Trezor Bridge provides a focused, secure link between your desktop/web wallet and hardware device. By keeping cryptographic operations on-device and providing a minimal trusted transport, Bridge simplifies secure use while preserving maximum protection for your private keys.
