Trezor Bridge

Trezor Bridge — Securely Connect Your Wallet

Trezor bridge is the official lightweight communication layer that connects your Trezor hardware wallet to web applications and Trezor Suite. Install once, connect securely, and manage your crypto with confidence.

Install & Start

What is Trezor bridge?

Trezor bridge is a small background application developed by the Trezor team that enables secure communication between your Trezor hardware wallet and supported browsers or desktop applications. It acts as a trusted intermediary — the bridge — routing signed transaction requests to your device and returning confirmations to the app. Without Trezor bridge installed, many web-based wallet interfaces cannot detect or interact with your Trezor device.

The software is intentionally lightweight and unobtrusive: once installed it runs with minimal resource impact, starts automatically when needed, and keeps your browsing environment tidy while maintaining reliable connectivity. It supports major operating systems and makes interactions consistent across different browsers and apps.

Key features

These features make Trezor bridge an essential piece of infrastructure for anyone who wants a seamless, trusted connection between hardware and web interfaces. It reduces friction while ensuring the hardware remains the single source of truth for keys and confirmations.

Getting started — step-by-step

Step 1 — Download

Visit the official Trezor website and download Trezor bridge for your operating system. Always download from the verified source to avoid counterfeit installers.

Step 2 — Install

Run the installer and follow the prompts. Trezor bridge installs quickly and will start running automatically in the background when required.

Step 3 — Connect

Plug your Trezor hardware wallet into your computer via USB. Open Trezor Suite or a supported web app — the app will detect your device through Trezor bridge.

Step 4 — Verify & Use

Confirm addresses and sign transactions on the device itself. Always verify details on the Trezor screen before approving. After confirmation, manage, send, and receive crypto confidently.

Step 5 — Update Regularly

Keep both Trezor bridge and your device firmware up to date for best compatibility and security. Official updates are published on the Trezor website.

Step 6 — Secure Backups

While Trezor bridge handles communication, your recovery seed (written down during device setup) is the only way to restore funds. Store it offline in a safe location.

Security & best practices

Trezor bridge is designed to preserve the core security model of the Trezor hardware wallet: private keys remain on the device and never leave it. Trezor bridge only passes encrypted messages between applications and the device; it does not have access to your seed or private keys. That said, follow these best practices:

Following these steps ensures that the convenience Trezor bridge provides never compromises the safety of your assets.

Why Trezor bridge matters

As web wallets and browser-based tools become more capable, the need for a secure, consistent communication layer is essential. Trezor bridge fills that role: it allows your hardware wallet to integrate with modern web apps while preserving the hardware-first security model. For everyday users and professionals alike, it makes safe crypto management practical without sacrificing protection.
