Empowering privacy and performance through invisible connection.
Trezor® Bridge® is the secure communication layer that connects your Trezor Hardware Wallet to desktop and web interfaces like Trezor.io/start and Trezor Suite. It operates silently in the background, translating messages between your computer and wallet, without ever storing, sharing, or exposing your sensitive information.
Created by SatoshiLabs, the Bridge is engineered for speed and integrity. It’s a minimalist yet powerful bridge of trust — ensuring that when you authorize a transaction, the signal reaches your hardware device through an encrypted, locally-contained channel.
Without Trezor Bridge, browsers can’t easily communicate with USB devices like your hardware wallet due to strict web security protocols. The Bridge acts as a cryptographic mediator — enabling your Trezor to interact with trusted apps like Trezor Suite or Trezor Login while keeping private keys locked inside the device.
Every action happens within your machine. No cloud access, no third-party relay, and no external dependencies — only your device and you.
The code behind Bridge is open for anyone to audit. It reflects the Trezor philosophy of transparency — what you see is what you run.
As browsers and operating systems evolve, Bridge ensures ongoing compatibility between Trezor Io Start, Trezor Suite, and the latest web security standards.
Once installed, Bridge creates a small local service on your system. When you access Trezor.io/start or open the Trezor Suite desktop app, it automatically detects your device. All commands — from verifying addresses to signing transactions — are routed securely through this local channel.
The Bridge acts as a universal translator between the Trezor firmware and user-facing tools. Whether you use Trezor Suite on desktop or the browser-based version, the Bridge ensures seamless data flow. It’s also critical for enabling smooth Trezor Login — the secure authentication method for compatible crypto services.
Beyond crypto transactions, Bridge contributes to firmware updates, message signing, and account management across multiple assets. Its presence makes each Trezor device more resilient to digital interruptions and unauthorized access attempts.
Keep these recommendations in mind to get the best from your Trezor Bridge experience:
It allows your computer to communicate with your Trezor Hardware Wallet safely and locally, ensuring your keys never leave the device.
Yes, Bridge is necessary for connecting your wallet on browsers or desktop setups that don’t natively support USB communication.
Absolutely. It’s open-source, independently reviewed, and follows strict security guidelines. Bridge only transmits commands — it never holds private data.
Restart your system or reinstall Bridge from Trezor.io/start. Ensure that no antivirus or firewall blocks the local port.
Yes, you can install Bridge on several systems. Each installation runs independently and only operates while your wallet is physically connected.
