Trezor Bridge is a lightweight software utility developed by SatoshiLabs that acts as a secure communication layer between your Trezor hardware wallet and your internet browser. It enables web-based wallets and applications, such as the Trezor Suite, to interact with your Trezor device for activities like managing crypto assets, signing transactions, and securing digital identities.
Before Trezor Bridge, communication between Trezor devices and browsers relied on browser extensions. However, as web technologies evolved and browser policies became stricter, a more stable and scalable solution became necessary. Trezor Bridge emerged as the answer—delivering a seamless, secure, and consistent user experience across major operating systems and browsers.
If you're using your Trezor One or Trezor Model T on a desktop browser, Trezor Bridge is required to establish a secure link between your wallet and Trezor Suite (or any supported third-party application).

Installing Trezor Bridge is a straightforward process. Here’s a quick step-by-step guide:
⚠️ Note: You do not need to install Trezor Bridge if you’re using Trezor Suite as a desktop application.
Here are some common issues users face and how to resolve them:
1. Device Not Recognized
2. Browser Blocked Communication
3. Bridge Not Installed Properly
Trezor Bridge is open-source and regularly maintained by the team at SatoshiLabs. The software runs locally and does not store any sensitive information. Since the Bridge facilitates encrypted communication, all transactions and actions require physical confirmation on your Trezor device—adding a robust layer of protection.
Moreover, Trezor Bridge only connects to verified web domains like suite.trezor.io or other trusted DApps. This ensures you're always in control of your digital assets.
With the deprecation of browser extensions for hardware wallets, Trezor Bridge becomes the preferred method for secure communication.
