What Is Trezor Bridge?
Trezor Bridge is a small software utility that allows your computer browser to communicate securely with your Trezor hardware wallet. It acts as a bridge between the Trezor device and supported web applications like Trezor Suite Web, providing encrypted, reliable, and direct communication without needing browser extensions.
It replaces the older Chrome and Firefox extensions, offering a more secure, streamlined experience across all major operating systems including Windows, macOS, and Linux.
Why Do You Need Trezor Bridge?
When you plug in your Trezor device and try to access Trezor Suite Web or other web-based wallets, your browser needs a way to communicate with the hardware. Browsers don't inherently support communication with USB-connected devices, which is where Trezor Bridge comes in.
- 🔐 Facilitates secure device communication over HTTPS
- 🌐 Works across Chrome, Firefox, Edge, and other browsers
- ⚙️ Automatically detects and pairs with your Trezor device
- 🚀 Enables browser apps to request signatures and wallet access
Without Trezor Bridge (or the desktop app), your Trezor device won’t be recognized by the browser, making it essential for web usage.
