The secure link between your Trezor hardware wallet and your computer.
Trezor Bridge is a lightweight background application developed by Trezor.io that enables smooth and secure communication between your Trezor hardware wallet and your web browser or desktop applications. It acts as the “bridge” between your device and services like Trezor Suite or third-party wallets.
Without Trezor Bridge, your browser wouldn’t be able to communicate properly with the hardware wallet. The Bridge ensures that transactions, authentication, and firmware updates are handled safely and efficiently, while keeping your private keys completely isolated on your device.
The Trezor Bridge is essential because most web browsers have gradually removed native USB access for security reasons. This means that direct device communication is not possible through standard browser interfaces alone.
In short, Trezor Bridge is the invisible backbone of your Trezor experience. Once it’s installed, everything “just works.”
When installed, the Bridge runs quietly in the background as a service on your computer. It listens for communication requests from supported browsers or the Trezor Suite App.
For example, when you initiate a transaction in Trezor Suite, the request passes through Trezor Bridge, which sends it to your hardware device. The device signs the transaction internally, then returns the signed data through the Bridge back to the application — all without ever exposing your private keys.
This architecture ensures complete isolation between your crypto secrets and your computer’s internet connection.
Installing Trezor Bridge is quick and easy. Follow these steps:
The Bridge will start automatically whenever you plug in your Trezor. No manual launch is required.
Some modern browsers, like Chrome, support a feature called WebUSB, which allows direct hardware communication without installing additional software. However, WebUSB support is limited and not available across all browsers or operating systems.
Trezor Bridge ensures universal compatibility and a consistent experience for all users. It’s particularly recommended for those using Firefox, Safari, or Linux-based systems, where WebUSB may not function reliably.
Trezor occasionally releases updates to improve performance, fix bugs, and maintain compatibility with newer browser versions. The update process is simple:
Trezor Suite often notifies users automatically when a Bridge update is required.

Security is at the heart of Trezor’s philosophy. Trezor Bridge ensures that sensitive data never leaves your hardware wallet. All cryptographic operations — such as signing transactions or verifying addresses — occur inside the device, not on your computer.
This combination of local isolation and open-source transparency makes Trezor Bridge a trusted tool for secure crypto management.
Trezor Bridge is compatible with:
It works with popular browsers including Chrome, Firefox, Brave, and Edge. After installation, Bridge launches automatically at startup and updates itself when necessary.
The Trezor Bridge is a crucial component in the Trezor ecosystem. It connects your hardware wallet to your computer securely, ensuring smooth transactions and communication without compromising your private keys. Whether you’re using Trezor Suite, web wallets, or browser integrations, Bridge guarantees that your hardware wallet operates as intended.
With its easy installation, cross-platform support, and transparent open-source design, Trezor Bridge continues to provide a safe and stable experience for cryptocurrency users around the world.
