What Is Trézór Bŕidge® and Why It Matters
Trézór Bŕidge® is a secure background service that allows your computer’s web browser or desktop application to communicate safely with your Trezor hardware wallet. Without it, browsers can’t detect your Trezor device directly. The Bridge acts as an encrypted channel between your hardware wallet and the official Trézór™ Suite interface.
It’s essential for users who prefer managing crypto through the web version of Trezor Suite or for connecting with other supported wallets such as Electrum or Mycelium. The Bridge ensures all communication is verified, encrypted, and free from interference by malicious scripts or fake browser plugins.
How Trézór Bŕidge® Works
When you plug in your Trezor hardware wallet, Trézór Bŕidge® identifies the device and securely relays information to the Trézór Suite.
It uses the local host connection (http://127.0.0.1) — meaning no data leaves your computer.
Transactions are signed inside your hardware wallet, never within the Bridge itself.
Security Architecture Overview
- End-to-End Encryption: Data between Suite ↔ Bridge ↔ Trezor device is protected.
- Device Verification: Every connection checks the hardware fingerprint to avoid tampering.
- No Cloud Storage: The Bridge never stores keys, balances, or seed phrases.
Installing Trézór Bŕidge®
To install Trézór Bŕidge®, go to the official download page: https://trezor.io/bridge/
The installer automatically sets up the service to start with your operating system. Supported platforms include Windows, macOS, and Linux. After installation, restart your browser and connect your Trezor device.
Connecting Your Device with Trézór Bŕidge®
Step 1: Launch Trézór™ Suite
Open the Trezor Suite app or visit the official web version. The Bridge runs in the background and detects your device automatically.
Step 2: Authorize Connection
When prompted, allow your browser to communicate through Trezor Bridge. Your device will flash a confirmation screen — verify the message before continuing.
Step 3: Authenticate with PIN or Passphrase
Enter your PIN or passphrase directly on the device to log in. Your computer never receives the actual PIN layout, ensuring maximum privacy.
Step 4: Access Crypto in Trézór™ Suite
Once connected, you’ll see your dashboard inside Trezor Suite. You can check balances, send and receive coins, or sign transactions safely.

Troubleshooting Bridge Connection Issues
Bridge Not Detected?
Reinstall the latest version of Trézór Bŕidge®, then restart your browser. Ensure that no VPN or firewall is blocking 127.0.0.1.
Device Still Undetected?
Try a different USB port or cable. For Linux users, check that you’ve installed the correct udev rules provided on the download page.
