Trezor Bridge

The Secure Gateway to Your Wallet® – Connecting Your Trezor Hardware Wallet to Your Digital Assets Safely and Seamlessly

What is Trezor Bridge?

Trezor Bridge is an essential software component that acts as a secure communication channel between your Trezor hardware wallet and your web browser or desktop applications. It facilitates the interaction between your Trezor device and wallet interfaces such as Trezor Suite, allowing you to safely manage your cryptocurrencies and digital assets.

As modern browsers increasingly restrict direct USB access for security reasons, Trezor Bridge provides the necessary bridge to overcome these limitations by running a background service on your computer that securely connects to your hardware wallet.

This software is open-source, regularly maintained, and developed by the SatoshiLabs team (the creators of Trezor). It is designed to be lightweight, transparent, and highly secure.

How Does Trezor Bridge Work?

To understand Trezor Bridge, it helps to know a bit about how hardware wallets and browsers communicate:

This architecture isolates USB device access to a trusted application on your system, improving security and compatibility.

Think of Trezor Bridge as the secure messenger that safely delivers your transaction requests from your browser to your Trezor wallet and back.

Security Features and Best Practices

Trezor Bridge plays a critical role in maintaining the security of your hardware wallet interactions. Here’s how it contributes to your safety:

Secure Communication Channel

Trezor Bridge establishes an encrypted and isolated communication channel between your computer and the hardware wallet. This reduces the risk of malware or malicious browser extensions intercepting your private keys or transaction data.

Open-Source Transparency

The Trezor Bridge source code is openly available for review by security researchers and the community. This transparency helps ensure that no backdoors or vulnerabilities are hidden in the software.

Minimal Attack Surface

Since Trezor Bridge only acts as a communication relay and does not store private keys or sensitive data itself, the potential attack surface is minimized.

Regular Updates

The Trezor team regularly releases updates to Trezor Bridge that patch bugs, improve compatibility, and enhance security. Keeping the software up to date is essential.
