Overview
Trezor Bridge runs as a small background service and exposes a secure local API that trusted applications use to detect and interact with the connected Trezor device. It avoids relying on browser USB integrations and provides a stable, cross-platform bridge.
Key highlights
1
Encrypted local channel
Only trusted apps can talk with the Bridge and commands are forwarded to the hardware device.
2
Cross-platform
Installers for Windows, macOS and Linux (AppImage / .deb / .rpm) are available.
3
Low footprint
Small runtime impact and automatic start options.
4
Regular updates
Optional auto-update keeps compatibility with Trezor Suite and firmware changes.
Quick install & verification
- Visit the official page at trezor.io/bridge and download the installer for your OS.
- Run the installer. On macOS, allow the app in System Preferences → Security & Privacy if prompted.
- Open Trezor Suite or your compatible wallet; Bridge will be detected automatically.
- Connect your Trezor device via USB and confirm the connection on the device screen.
Troubleshooting & tips
- Try another USB cable or port if the device isn't detected.
- On Windows, running the installer as Administrator may be necessary for drivers.
- Temporarily disable conflicting apps that may block USB connections or the local HTTP port used by Bridge.
Checksum & signature verification (recommended)
After downloading, verify the file integrity using checksums and signatures provided on the official site. Example (on Linux/macOS):
$ sha256sum trezor-bridge-setup.deb # compare the output with the checksum listed at trezor.io/bridge/
