What is Trezor Bridge®?

Trezor Bridge® is a small, secure connector that runs on your computer and enables reliable, private communication between your hardware wallet® and Trezor Suite® or browser-based dApps. As the secure gateway, Trezor Bridge® makes sure requests reach the device and responses return to the app without exposing private keys. Trezor Bridge® preserves on-device signing and strong custody while enabling convenient Web3 interactions.

Install & Connect — Quick Steps to Start

1

Download from the official source

Always download Trezor Bridge® from the official site or verified channels. Using the official download reduces supply-chain risk and ensures you get the authentic Trezor Bridge® installer for your OS (Windows, macOS, Linux).

2

Run the installer and allow local connectivity

Install Trezor Bridge® and accept the minimal local permissions it requires. Bridge runs locally to enable USB or WebUSB communication between the device and Trezor Suite® or compatible dApps.

3

Open Trezor Suite® and connect your hardware wallet®

Open Trezor Suite®, plug in your hardware wallet®, and follow the on-screen prompts. Bridge will handle the secure handshake; you will confirm actions and PINs on the hardware device itself.

4

Review and sign on-device

Always verify transaction details on your hardware wallet® screen before signing. Trezor Bridge® only transmits the request — all sensitive signing operations occur on-device and remain protected by the device's secure element.

Security & Privacy Principles

Trezor Bridge® is designed to minimize data exposure. It does not store recovery seeds, private keys, or PINs, and it communicates only through local endpoints. To maximize security: download Bridge from official sources, keep both Bridge and device firmware up to date, and never enter your recovery seed or private key into a browser. Treat Trezor Bridge® as the secure gateway that preserves the hardware wallet® model of custody — private keys never leave the device.

Local-only connectivity

Bridge creates a private local channel; nothing sensitive is transmitted off your computer without your explicit consent.

Compatibility

Bridge supports Trezor Suite® and many Web3 dApps, enabling broad hardware wallet® workflows and integrations.

Lightweight & trusted

Small footprint, minimal permissions, and regular security updates ensure Bridge remains a trusted connector for managing crypto.

Troubleshooting & Best Practices

If your device is not detected: try a different USB cable, verify Bridge is running, restart Trezor Suite®, and check system prompts for permissions. If the browser integration is needed, follow official guidance for enabling WebUSB or using the supported helper. Keep Bridge and Suite updated to the latest official versions and verify firmware updates directly on the device.

Pro tip: always verify transaction details on the hardware wallet® screen — do not rely solely on the app preview.
