# Trézor Bridge® | Introducing the New Trezor® App

Cryptocurrency security is an important consideration for anyone who owns or manages digital assets. Hardware wallets provide an additional layer of protection by keeping private keys isolated from internet-connected devices. However, connecting a hardware wallet to a computer and using it with compatible applications requires reliable communication software. This is where **Trezor Bridge** becomes useful.

Trezor Bridge is a communication component designed to help a computer browser interact with a Trezor hardware wallet. It allows supported web applications to communicate with the physical device, making it easier to manage cryptocurrency accounts, review transactions, and perform wallet-related activities.

For users who want a convenient way to connect their hardware wallet, understanding Trezor Bridge is an important part of learning how the Trezor ecosystem works. This guide explains its purpose, installation process, features, compatibility, troubleshooting methods, and security considerations.

## **What Is Trezor Bridge?**

Trezor Bridge is software that facilitates communication between a Trezor hardware wallet and compatible browser-based applications. It operates in the background and helps supported websites recognize and communicate with an attached Trezor device.

A hardware wallet does not expose its private keys to the computer. Instead, sensitive signing operations take place within the physical device. Trezor Bridge helps establish the communication channel needed for applications to request information or submit transactions for approval.

Without a suitable communication method, a browser-based wallet interface might not detect the connected hardware wallet correctly.

Trezor Bridge is particularly relevant for users accessing compatible wallet interfaces through desktop browsers.

## **Why Is Trezor Bridge Important?**

Trezor Bridge helps simplify the connection between hardware wallets and computers. It provides several practical benefits:

**1. Device Communication:** It helps compatible applications communicate with an attached Trezor device.

**2. Convenient Wallet Access:** Users can connect their hardware wallet to supported applications without relying on complicated manual connection procedures.

**3. Transaction Interaction:** Applications can send transaction information to the device for review and approval.

**4. Background Operation:** Once properly installed and running, the software generally works in the background.

**5. Improved Compatibility:** It supports communication between supported browsers, computer operating systems, and Trezor hardware wallets.

These functions make Trezor Bridge a useful component of the broader hardware wallet experience.

## **Understanding How Trezor Bridge Works**

Trezor Bridge acts as an intermediary between compatible applications and the hardware wallet. When a user connects a device, the application attempts to establish communication through an available transport method.

The communication process generally involves:

1. Connecting the Trezor hardware wallet to a computer.
2. Opening a compatible wallet application.
3. Allowing the application to detect the connected device.
4. Establishing communication through a supported connection method.
5. Reviewing requested information or transactions on the hardware wallet.
6. Confirming sensitive operations directly on the physical device.

It is important to understand that Trezor Bridge is not itself a cryptocurrency wallet, exchange, or storage platform. It is a connectivity component.

**An important update:** Standalone Trezor Bridge has been deprecated. Trezor has transitioned to newer communication methods, including nodeBridge integrated into its software ecosystem. Therefore, users should follow current official installation instructions rather than downloading older standalone Bridge installers.
