What is Trezor Bridge?
Trezor Bridge is an official background application that enables communication between your Trezor hardware wallet and browser-based or desktop cryptocurrency applications. It acts as a trusted channel so wallets can interact with your device without exposing private keys.
Key features
- Universal compatibility: Works with major browsers and desktop environments.
- Secure transport: Uses local host communication; the device signs transactions offline.
- Automatic updates: Seamless version checks ensure you run the official release.
- Small footprint: Lightweight daemon/service with low resource use.
Quick install & verify
Download the official package for Windows, macOS, or Linux. After installation, verify the signature (or checksum) supplied by the official Trezor site. Never install builds from unknown third-party mirrors.
Security best practices
- Always verify official checksums/signatures before running installers.
- Keep your Trezor firmware and Bridge up to date.
- Connect only to trusted web wallets and check the URL for TLS and domain authenticity.
- Use a strong passphrase and a secure physical backup for your recovery seed.
Troubleshooting
If a wallet doesn’t detect your device: ensure Bridge is running, the device is unlocked, and your cable is data-capable. On browsers, close other applications that might monopolize the USB port. If issues persist, reinstall Bridge and reboot.
