Trezor Bridge® | Connect Your Trezor to Web Browsers
Connecting a hardware wallet to a web browser should be seamless, secure, and reliable. That’s exactly what Trezor Bridge® delivers. As the essential communication layer between your Trezor hardware wallet and your computer’s web environment, Trezor Bridge makes it possible for your browser to recognize, authenticate, and communicate with your device without relying on outdated plugins or insecure methods.
In this in-depth guide, we explore everything you need to know about Trezor Bridge, including what it is, how it works, how to install it, troubleshooting, compatibility, and best security practices. Whether you’re new to Trezor or an experienced crypto user, this resource will help you unlock the full power of your device.
What is Trezor Bridge®?
Trezor Bridge® is a lightweight application developed by Trezor to allow secure communication between a Trezor hardware wallet and your web browser. It acts as a safe communication layer that ensures your device can interact with Trezor Suite, web wallets, and approved dApps.
Before Bridge existed, users depended on browser extensions or plugins. However, those methods became outdated, less secure, and increasingly incompatible with modern browsers. With the introduction of Trezor Bridge, hardware wallet communication became stable, fast, and far more secure.
Key Features
Secure communication between your Trezor device and supported browsers
Automatic recognition of your device
Compatible with Trezor Suite (web and desktop)
Supports multiple operating systems (Windows, macOS, Linux)
Minimal impact on system resources
Regular updates for security and performance
Why Do You Need Trezor Bridge®?
If you’re using a Trezor hardware wallet—whether Trezor Model One, Trezor Model T, or Trezor Safe 3—your browser cannot communicate with it directly. Browsers don’t have built-in support for USB-connected hardware wallets, so a communication layer is required.
Trezor Bridge solves this problem by acting as the secure translator or messenger between your device and the browser.
You need Trezor Bridge for:
Accessing Trezor Suite Web
Performing crypto transactions
Managing tokens, coins, and NFTs
Connecting Trezor to third-party services
Updating firmware through the browser
Initial Trezor setup (when not using desktop Suite)
Without Trezor Bridge, your browser simply won’t detect the hardware wallet, making it impossible to use essential features.
How Trezor Bridge® Works
Trezor Bridge operates in the background once installed. Whenever you plug in your Trezor device, Bridge recognizes it and establishes a secure communication tunnel between your browser and the hardware wallet.
The process works like this:
User connects the Trezor device via USB
Trezor Bridge detects the device automatically
Browser (e.g., Chrome, Firefox, Brave) sends request → “Is a Trezor connected?”
Bridge replies and creates a secure communication path
Trezor Suite or website loads the device interface
User approves actions directly on the Trezor screen
This mechanism ensures that:
No sensitive information is passed through the browser
Private keys never leave the hardware wallet
Communication stays encrypted and isolated
