📌 What is Trezor Bridge?

Trezor Bridge is a communication tool (a small piece of software) that connects your Trezor hardware wallet to your web browser and the Trezor Suite (or legacy Trezor Wallet) interface. Think of it as a secure “bridge” that lets your computer and your Trezor device talk to each other.

Key points:

• It replaces older browser extensions like Trezor Chrome Extension.
• Works silently in the background.
• Required for Trezor wallets to work with web browsers that don’t natively support USB communication (like Chrome, Firefox, or Edge).

✅ Why is Trezor Bridge Important?

• Secure Communication: It handles data transfer between your Trezor device and your browser without exposing your private keys.
• Universal Support: It works across all major browsers.
• Seamless Updates: Makes it easy to use Trezor Suite without needing special plugins.

🖥️ How Does Trezor Bridge Work?

1. You install the Trezor Bridge software on your computer.
2. When you connect your Trezor hardware wallet, the Bridge securely passes data between the device and the Trezor Suite web interface.
3. Your private keys never leave the Trezor device; the Bridge only transfers public data (like signed transactions).

🔗 Difference Between Trezor Bridge and WebUSB

• Trezor Bridge: Needed for browsers that don’t support WebUSB (or when WebUSB fails).
• WebUSB: Modern browsers like Chrome can communicate directly with USB devices without Bridge, but it can be unreliable.

For best compatibility, Trezor recommends installing Bridge as the default method.

🔒 Is Trezor Bridge Safe?

Yes! Trezor Bridge is developed by SatoshiLabs, the creators of Trezor.
