What is Trezor Bridge?
Trezor Bridge is a small helper app that lets your web browser talk to your Trezor hardware wallet. It acts as a bridge between the device and crypto apps so you can manage your wallets securely.
Why it matters
Trezor devices are hardware wallets — they keep private keys offline. The Trezor Bridge safely routes signed transactions and device requests between your browser and the physical device while reducing direct browser access to USB hardware.
Quick Install (Windows / macOS / Linux)
Follow these simple steps to get started.
- Download Trezor Bridge from the official Trezor site.
- Run the installer and follow on-screen instructions.
- Open your browser and visit a supported wallet web app (e.g., Trezor Wallet).
- Connect your Trezor device and approve the connection on the device screen.
Tip: If your browser has cached an older method, restart the browser after installing the Bridge.
Troubleshooting
Browser not detecting device?
- Make sure Bridge is running in your system tray (Windows) or menu bar (macOS).
- Disable browser extensions that block USB devices.
- Try a different USB port or a direct USB cable (avoid hubs).
Still not connecting?
- Update Bridge to the latest version and reboot.
- Check your operating system privacy settings to allow device access.
