Trezor Bridge — Secure Connection for Your Trezor

What Is Trezor Bridge?

Trezor Bridge is the communication layer that connects your Trezor hardware wallet to web-based or desktop interfaces such as Trezor Suite. It allows your computer’s browser or application to securely recognize the device, exchange encrypted commands, and sign transactions — without exposing sensitive data to the internet.

Developed and maintained by SatoshiLabs, Trezor Bridge replaces the older browser plug-ins and drivers used in early versions of the Trezor Wallet. It’s lightweight, fast, and designed for maximum security and compatibility across platforms.

Whether you’re sending Bitcoin, managing tokens, or verifying messages, Trezor Bridge ensures every communication between your hardware wallet and computer remains secure, stable, and authentic.

Security Architecture

Trezor Bridge is more than just a driver — it’s an integral part of the Trezor security model. Its design philosophy revolves around isolation, authentication, and encryption:

Isolated Communication: Bridge ensures that the only way to interact with your hardware wallet is through verified, signed, and trusted channels.
End-to-End Encryption: Every instruction between your browser or app and your Trezor device is encrypted, preventing data leaks or manipulation.
Device Verification: The Bridge verifies the hardware’s authenticity before allowing transactions or key exchanges.
Phishing Resistance: By eliminating the need for browser extensions, Bridge removes one of the most common phishing attack vectors in crypto.
Zero Data Collection: Trezor Bridge never stores, tracks, or transmits personal data — it’s purely a secure communication tunnel.

Combined with the physical security of Trezor hardware wallets, the Bridge adds another layer of assurance for anyone interacting with blockchain assets.

How to Install Trezor Bridge

Installing Trezor Bridge is simple and requires only a few minutes. Follow these steps to get started:
