The official Trezor Bridge is your safe communication channel between computer and hardware wallet. Reliable, lightweight, and open-source — it ensures your Trezor connects securely with the Trezor Suite App, without ever exposing private data.
Trezor Bridge is the foundational communication layer that links your Trezor hardware wallet with desktop or web applications like Trezor Suite. Acting as a secure messenger, it enables encrypted data exchange between the device and the computer without ever revealing sensitive information. This intermediary software ensures smooth operation across major operating systems including Windows, macOS, and Linux.
Unlike browser extensions, Trezor Bridge runs quietly in the background once installed. It verifies that your hardware wallet communicates only through authenticated interfaces, protecting you from phishing and fake wallet applications. It’s part of Trezor’s long-standing philosophy of combining open-source transparency with rock-solid device security.
Bridge establishes a trusted, encrypted connection between your hardware wallet and Trezor Suite, preventing unauthorized access and tampering.
Works seamlessly on Windows, macOS, and Linux, ensuring consistent functionality and user experience across systems.
Recognizes connected devices instantly, eliminating the need for browser-based communication or extra permissions.
Every line of code is publicly available on GitHub, allowing independent verification and fostering community trust.
Installing Trezor Bridge is straightforward. Visit trezor.io/start and follow the installation prompts for your operating system. Once installed, Bridge runs silently in the background and automatically detects your Trezor device whenever it’s connected.
For most users, no further configuration is needed. You’ll know Bridge is working when Trezor Suite instantly recognizes your connected wallet and displays its status. For advanced users, settings can be customized via the system tray to restart, stop, or uninstall the service.
The design of Trezor Bridge emphasizes one core principle: your private keys must never leave your hardware wallet. Bridge transmits only encrypted messages between the computer and your Trezor, leaving sensitive operations confined to the device itself. This isolation prevents malware or keyloggers on the host machine from gaining access to your funds.
Additionally, Trezor Bridge is digitally signed and verified at installation. Users can check the software’s signature and integrity before running it. Open-source repositories enable independent audits, which further solidify the transparency and reliability of the platform.
“With Trezor Bridge, you don’t just connect a wallet — you connect peace of mind. Its transparent, encrypted design makes it one of the most trusted interfaces in the hardware wallet ecosystem.”
Occasionally, users may encounter connection issues after an operating system update or when switching between browsers. Most problems can be solved by reinstalling the latest version of Trezor Bridge or restarting the computer after installation. Trezor’s support page offers step-by-step guides to resolve these issues.
Regular updates are crucial. They include compatibility fixes, improved detection routines, and refined security layers. Always download Bridge directly from Trezor.io to avoid tampered or malicious copies.
Bridge acts as the silent backbone of Trezor Suite, managing all communications between the Suite and your hardware wallet. Without it, the Suite wouldn’t be able to read device data or authorize transactions securely. Together, they form a complete self-custody ecosystem that empowers users to manage cryptocurrencies safely from desktop or browser environments.
When you connect your Trezor via Bridge, each transaction is confirmed physically on the device. Even if the computer were compromised, unauthorized transfers couldn’t be executed without your manual confirmation.
For developers and security researchers, Bridge provides a local API interface that allows interaction with Trezor devices for testing, automation, or integration with third-party wallets. This capability ensures that Bridge is not just a background service but also a flexible development tool that can expand the usability of Trezor across ecosystems.
