Trézor Bridge® | Introducing the New Trezor® App

Trézor Bridge® is the official connectivity software developed for Trezor hardware wallets — including the Trezor Model One and Trezor Model T — that enables secure, seamless communication between your wallet and the New Trezor App or web-based wallet interfaces. It has been introduced as a modern replacement for older browser extensions and provides a robust foundation for managing cryptocurrency securely from desktop and web environments.

What Trézor Bridge® Is

At its core, Trézor Bridge® is a lightweight background application that runs on your computer and acts as a secure intermediary between your Trezor hardware wallet and software interfaces such as:

The New Trezor App (evolved from Trezor Suite)

Browser-based wallet interfaces

Third-party crypto wallets and decentralized apps (dApps) that support hardware wallet connections

Unlike deprecated Chrome-only plugins or legacy browser connectors, Bridge runs as a standalone system service that listens locally and routes encrypted communication between the wallet and the app or browser.

Why It Matters Secure Connectivity

Bridge ensures that private keys and recovery seeds never leave your hardware wallet, preserving the core security promise of cold-storage devices.

All transaction signing and key operations are handled by the Trezor device itself — Bridge merely facilitates encrypted messaging between software and hardware.

Compatibility Across Platforms

Trézor Bridge® works on major desktop systems, including:

Windows (10, 11)

macOS (Intel and Apple Silicon)

Linux distributions (Ubuntu, Fedora, Arch, etc.)

It also supports modern browsers including Chrome, Firefox, Brave, and Edge, enabling broad accessibility for both new and advanced users.

Improved Reliability and Usability

By replacing browser extensions — which were prone to compatibility problems and security limitations — Bridge provides:

Faster and more reliable device detection

Encrypted USB communication

Better handling of multiple wallet or browser sessions

Reduced connection errors and smoother transaction workflows

These improvements make hardware wallet interactions more seamless, especially for users who manage assets via browsers or web apps.

Introducing the New Trezor App

Alongside Trézor Bridge®, Trezor’s updated software environment includes the New Trezor App, a modern application designed to make cryptocurrency management simpler and more secure.

Core Features of the New Trezor App

User-Friendly Interface: Intuitive dashboard for viewing portfolios, balances, and transaction history.

Enhanced Security: All sensitive operations require confirmation on the hardware device.

Open-Source Transparency: Both the wallet interface and Bridge are open-source, enabling community audits and trust.

Broad Support: Works with a variety of cryptocurrencies and integrates with popular third-party services.

The New Trezor App essentially replaces older versions like Trezor Suite, giving users a more modern, cohesive experience for managing their digital assets.

How Trézor Bridge® Works

Local Service – Bridge installs on your computer and runs as a background service that listens on a local port.

Device Detection – When you plug in your Trezor hardware wallet, Bridge detects the connection and establishes a secure communications channel.

Encrypted Messaging – Commands from the app or browser are encrypted and forwarded to the Trezor device.

Hardware Confirmation – All sensitive operations (transaction signing, address generation, firmware updates) are confirmed manually on the device screen.

Result Relay – The signed results are relayed back through Bridge to the requesting app or web interface.

Because it operates locally and does not expose any external network, Bridge significantly lowers the risk of remote exploitation.

Installing Trézor Bridge®

To get started with Trézor Bridge®:

Visit the official Trezor site — typically via https://trezor.io/start or the specific bridge download page.

Select your operating system and download the appropriate installer.

Run the installer and follow the on-screen prompts.

Restart your browser (if necessary).

Connect your Trezor device via USB — Bridge should detect it, after which the New Trezor App or supported wallets can interact with it seamlessly.

Once installed, Bridge runs silently in the background — you typically do not need to open it manually.

Security Benefits

Trézor Bridge® enhances security in several ways:

Encrypted Communication – Ensures data transferred between your hardware wallet and software is securely protected.

No Key Exposure – Private keys remain on the hardware device at all times — Bridge never stores or transmits them.

Manual Confirmations – Users must physically confirm transactions or actions on the Trezor device screen.

Open-Source Code – Bridge’s code can be audited by the community, promoting transparency and trust.

These protections ensure that even if your computer or browser is compromised, unauthorized transactions cannot occur without physical confirmation.

When You Need Bridge

Trézor Bridge® is required when you are:

Using a web browser interface to manage your Trezor wallet.

Connecting to third-party wallets or decentralized apps that rely on Bridge for hardware wallet communication.

Your browser or operating system lacks native WebUSB support.

If you use the New Trezor App desktop version, Bridge may be included or unnecessary because the desktop app can communicate directly with USB hardware.

Final Notes

Trézor Bridge® remains a foundational piece of the Trezor ecosystem, enabling secure, encrypted interactions between hardware wallets and software interfaces. It supports broad browser and OS environments while preserving the security model of hardware wallets — keeping private keys offline and requiring physical confirmations for all sensitive actions.

Always download Bridge from official Trezor sources to avoid counterfeit or malicious copies and ensure the most secure crypto management experience.
