The invisible guardian of your cryptocurrency transactions.
Trezor Bridge is a lightweight application designed to run in the background of your computer. Its primary function is to facilitate communication between your Trezor hardware wallet and supported web browsers like Chrome, Firefox, and Brave. Before Trezor Bridge, users had to rely on browser plugins or extensions, which often faced compatibility issues and security limitations.
By installing Trezor Bridge, you create a direct, local communication channel (running on 127.0.0.1) that allows the Trezor Suite web interface and other third-party wallets (like MetaMask or MyEtherWallet) to detect and interact with your device. It handles the complex cryptographic handshakes required to sign transactions without ever exposing your private keys to the internet.
This software is completely open-source, verifiable, and designed with a "security-first" architecture. It does not have a graphical user interface (GUI) because it is a system service meant to work silently and efficiently. Once installed, it automatically starts when you connect your Trezor device, ensuring a seamless user experience.
Why millions of users trust Trezor Bridge for their crypto operations.
Trezor Bridge operates locally on your machine, eliminating the need for vulnerable browser extensions. It ensures that all communication between your device and the browser is encrypted and authenticated.
Optimized for performance, the Bridge reduces latency in device detection and transaction signing. Experience smoother interactions with Trezor Suite and third-party dApps.
Works seamlessly with all major operating systems and browsers. Whether you use Chrome, Firefox, or Brave, Trezor Bridge provides a consistent connection standard.
Once installed, the Bridge runs as a background process (trezord). You don't need to open or configure it manually; it wakes up automatically when needed.
No data is sent to external servers. The communication remains strictly between your hardware device and the local computer, preserving your financial privacy.
The code is fully open-source and available on GitHub. This transparency allows security researchers to audit the software, ensuring no backdoors exist.
A simple yet sophisticated connection process.
Download and install the Trezor Bridge installer for your operating system. The installation wizard will guide you through the quick setup process.
When you plug in your Trezor device via USB, the Bridge service (trezord) detects the hardware connection instantly.
When you visit Trezor Suite or a compatible wallet, the website sends a request to the Bridge (localhost:21325). The Bridge relays this request to your device.
You confirm the action on your physical Trezor device. The signed data is sent back through the Bridge to the browser to broadcast the transaction.

Common solutions if your device isn't being detected.
Sometimes browser cache can interfere with the connection. Try clearing your cache or using Incognito/Private mode.
Ensure you are using a data-capable USB cable. Some cables are for charging only and won't transmit data.
If the trezord process isn't running, try uninstalling and reinstalling the latest version of Trezor Bridge.
Strict firewall rules or VPNs might block the local connection (127.0.0.1). Temporarily disable them to test.
