Installing Trezor Bridge
Step 1: Download from Official Source
Always download Trezor Bridge from the official Trezor website. Avoid third-party websites to prevent exposure to malware or compromised files.
Step 2: Installation by Operating System
- Windows: Run the downloaded `.exe` installer and follow on-screen prompts.
- macOS: Open the `.dmg` file, drag Bridge to Applications, and approve permissions if requested.
- Linux: Use the provided `.deb` or `.rpm` packages, or compile from source if your distribution requires it.
Step 3: Verify Installation
After installation, connect your Trezor and open Trezor Suite. If the device is recognized, Bridge is working correctly.
Configuring Trezor Bridge
Bridge runs in the background and usually requires no extra configuration. However, advanced users may benefit from fine-tuning settings.
Check Running Status
On most systems, you can confirm Trezor Bridge is active by visiting http://127.0.0.1:21325/status/ in your browser.

Bridge updates automatically with new Trezor Suite releases. Keeping it updated ensures compatibility and security patches are applied.
Security Best Practices
- Never install Bridge from unofficial sources.
- Keep your operating system updated.
- Run only one instance of Bridge at a time.
- Do not disable Bridge services unless troubleshooting.
- Verify device prompts on your Trezor screen — never trust only your computer display.
