Trezor Bridge — Local USB connector for secure wallets

Connect your hardware wallet to your browser and desktop apps quickly and securely.

Why Trezor Bridge?

Trezor Bridge provides a robust, easy-to-install bridge between your desktop or browser and your Trezor hardware device. When you install Trezor Bridge you get a small, fast helper that handles the low-level USB communication so your wallet apps can operate without extra friction.

Built for security

The Trezor Bridge workflow isolates device communication from web apps and simplifies updates. Trezor Bridge reduces attack surface by limiting direct browser access to USB devices while offering a single trusted connector.

Simple setup

Download, run the installer, and your browser will detect your Trezor device automatically. Trezor Bridge runs in the background and starts when your computer does.

Cross-platform

Trezor Bridge supports Windows, macOS, and major Linux distributions so you can connect from your preferred environment.

How it works

When you connect a Trezor device, the Trezor Bridge service negotiates a local channel between the hardware and authorised applications. This local server approach lets wallets request cryptographic operations without ever exposing your private keys to remote servers. Trezor Bridge handles the transport while your device keeps keys offline.

FAQ

Q: Do I need Trezor Bridge?

A: If you use Trezor hardware with desktop wallet apps or with browsers that restrict direct USB access, installing Trezor Bridge is recommended.

Q: Is Trezor Bridge safe?

A: Yes. Trezor Bridge is designed to limit exposure and keep cryptographic keys on your device. The Trezor Bridge process only facilitates communication; it does not store your keys.

Security & Privacy

We engineered Trezor Bridge so the minimum necessary permissions are requested. The service uses a local-only endpoint and never sends sensitive information to external servers. Installing Trezor Bridge keeps key operations isolated to your device.
