Trezor Bridge — The Communication Layer Between Your Wallet and Browser
Trezor Bridge is a small background program that allows your Trezor hardware wallet to communicate securely with your web browser. Think of it as a translator that helps websites like Trezor Suite Web talk to your physical Trezor device.
Without it, your browser wouldn’t properly detect or interact with your wallet.
🔍 What Exactly Is Trezor Bridge?
Trezor Bridge is software developed by SatoshiLabs to replace older browser extensions. Modern browsers limit direct USB access for security reasons, so Bridge acts as a secure middle layer.
It runs quietly in the background and enables:
- Device recognition
- Secure communication
- Transaction confirmation flow
- Firmware checks
You don’t need to open it manually — it works automatically.
🧩 Why Trezor Bridge Is Needed
Browsers like Chrome, Firefox, and Edge are designed to protect users from unsafe device connections. Because of these restrictions, websites cannot directly access hardware wallets.
Trezor Bridge solves this by:
✔ Creating a secure local connection
✔ Allowing encrypted communication
✔ Verifying device authenticity
✔ Preventing malicious scripts from accessing wallet data
⚙️ How It Works
- You plug your Trezor into the computer
- You open Trezor Suite (web version)
- The browser sends a request
- Trezor Bridge relays the request securely to your device
- You confirm actions physically on the Trezor
At no point are private keys exposed to your browser or the internet.
💻 Supported Systems
Trezor Bridge works on:
- Windows
- macOS
- Linux
It’s lightweight and uses very little system memory.

🚀 When Do You Need It?
You need Trezor Bridge when:

- Accessing advanced web wallet tools
If you use the desktop version of Trezor Suite, Bridge is usually not required because communication is built-in.

⚠️ Important Safety Reminder

Bridge will never ask for these.
🎯 In Simple Words
Trezor Bridge is the secure connector that lets your Trezor talk to the web safely — like a guarded tunnel between your device and your browser.
