What is Trezor Bridge?
Trezor Bridge is a small background application that enables your browser to communicate with your Trezor device over USB. It provides a secure, signed channel between web apps (like Trezor Suite or compatible third-party wallets) and the hardware wallet, ensuring that transaction signing and device prompts are handled on the device itself.
Quick install & setup
- Download Trezor Bridge from the official Trezor website (always verify the domain).
- Run the installer and allow the application to run in the background.
- Plug in your Trezor device; your browser will detect Bridge and route requests to the device.
- Open Trezor Suite or a supported web app and follow on-screen instructions to connect.
Supported browsers & platforms
Trezor Bridge works with modern browsers that support native messaging and has installers for Windows, macOS, and Linux. For best results use the latest stable browser versions and keep Bridge updated to the newest release.
Security notes
- Never install Bridge from unofficial sources. Always download from the Trezor domain.
- Device confirmations and PIN entry occur on the Trezor device — never enter your PIN or recovery seed into the browser.
- Keep Trezor firmware and Trezor Suite up to date to benefit from security fixes.
Troubleshooting
- If your device isn't recognized, try a different USB cable or port and relaunch Bridge.
- On macOS, confirm security settings if the OS blocks the installer; allow the app in System Settings.
- Check for conflicting apps that may claim USB devices (some virtualization or security tools) and temporarily disable them.
