Enabling safe and seamless communication between your Trezor hardware wallet and your desktop environment.
Trezor Bridge is a background application that enables secure communication between your Trezor hardware wallet and supported web interfaces, such as Trezor Suite. Unlike browser extensions, Trezor Bridge works across all major browsers and operating systems, acting as a communication layer that ensures your device interacts safely with the online world.
Whether you're sending crypto, verifying addresses, or checking your balance, Trezor Bridge plays a vital role in keeping your interactions private and secure.
When using a Trezor hardware wallet, your private keys never leave the device. However, your computer still needs a way to securely send and receive information to and from the device. This is where Trezor Bridge comes in.
Trezor Bridge operates as a local server on your machine. Once installed, it listens for commands from Trezor Suite or other supported web apps. When you interact with your wallet, the commands are sent through the Bridge to the device, processed, and returned securely.
This local communication model reduces exposure to online threats and bypasses limitations of browser-based communication methods.
After installation, Trezor Bridge runs in the background without any visual interface. You can confirm it's working by accessing http://127.0.0.1:21325/status/ in your browser.
Even though Trezor Bridge is designed for stability, users may occasionally encounter issues. Here are some common problems and their solutions:
Trezor Bridge was designed with security as a top priority. It doesn't transmit any sensitive information over the internet. Instead, it uses secure, encrypted local communication between your device and your computer.
Some newer platforms use WebUSB to communicate with hardware wallets directly through the browser. While convenient, WebUSB has compatibility limitations and potential security concerns. Trezor Bridge provides a more consistent and secure experience across platforms.
| Feature | Trezor Bridge | WebUSB |
|---|---|---|
| Browser Compatibility | All major browsers | Limited (e.g., not supported on Firefox) |
| Security | Encrypted local communication | Exposes device directly to browser |
| User Control | Manual installation ensures awareness | Often automatic, less user control |
Regular updates ensure compatibility with your device and the latest security patches. To keep Trezor Bridge up to date:
Trezor Bridge is a foundational component of the Trezor hardware wallet experience. It ensures secure, reliable, and private communication between your wallet and your computer. Whether you're a long-time crypto holder or just getting started, using Trezor Bridge guarantees you're interacting with your assets in the safest way possible.
As crypto continues to evolve, Trezor remains committed to offering the highest standards in wallet security — and Trezor Bridge is a major part of that mission.
