Trézór Bridge® is an official communication software developed by SatoshiLabs that enables secure interaction between your Trezor hardware wallet and your computer browser or desktop applications like Trezor Suite. As the essential “bridge” between your wallet and user interface, it ensures seamless access, transaction signing, and wallet management, all without compromising security.
Unlike browser plugins or extensions that often introduce security risks, Trézór Bridge® offers a robust, native solution to connect your Trezor Model One or Trezor Model T device with confidence. It replaces the now-deprecated Chrome WebUSB and ensures compatibility with most modern operating systems and browsers.
Security and privacy are the cornerstones of crypto self-custody. Trezor devices were built to keep your private keys offline and your funds under your control. However, to view balances, send transactions, or update firmware, your device must communicate with a user interface like the Trezor Suite. That’s where Trézór Bridge® comes in.
Here’s why it matters:
Trézór Bridge® is designed to maintain the air-tight security model of Trezor while enhancing user accessibility and platform compatibility.
When installed, Trézór Bridge® runs silently in the background as a service. It listens for requests from interfaces like Trezor Suite or supported third-party wallets, then securely routes those requests to your connected Trezor device.
Each action—whether it’s viewing your wallet, signing a transaction, or exporting your public key—is verified and confirmed on your Trezor hardware screen. This ensures that even if your computer is compromised, attackers can’t steal your crypto.
The bridge never stores your private data, nor does it interfere with your device's offline security architecture. It’s simply a secure channel between your hardware and your interface.
Using Trézór Bridge® is simple. Here’s how to get started:
Visit the official Trezor Bridge page and download the version compatible with your operating system.
Launch the downloaded file and follow the on-screen instructions. Installation takes less than a minute.
Plug in your Trezor hardware wallet using a USB cable. Make sure it’s properly recognized by your system.
Go to suite.trezor.io and launch the web or desktop application. Trézór Bridge® will automatically establish a secure connection between your Trezor and the suite.
Most users experience a smooth setup, but if you encounter issues:
trezord.exe. On Mac/Linux, verify the background service is active.For more help, visit the Trezor Support Portal.
Using the official Trézór Bridge® ensures maximum safety for your assets. Third-party tools and browser extensions can be vulnerable to phishing or man-in-the-middle attacks. Trezor’s developers intentionally built this secure channel to keep every transaction interaction clean and authentic.
When using Trezor Suite with Trézór Bridge®, you eliminate the reliance on cloud services or plugins that may compromise privacy. This is crucial for users dealing with high-value portfolios, decentralized finance (DeFi) applications, or even institutional storage.
Trézór Bridge® is primarily designed for use with:
It provides flexibility across multiple chains and assets while staying loyal to the offline, hardware-protected ethos of Trezor.
The Trézór Bridge® is open-source, licensed under GPL, and is frequently audited by security researchers. It introduces no vulnerabilities, stores no private information, and acts only as a data pass-through service between verified endpoints. In short: it respects your sovereignty while enabling connectivity.
In the crypto space where scams and exploits are rampant, Trezor stands as a pillar of self-custody security. The bridge is not an exception—it’s a continuation of that legacy.
Trézór Bridge® is not just a connector—it’s a key security component in the Trezor ecosystem. By eliminating browser-based vulnerabilities and ensuring direct device communication, it helps users maintain true ownership of their crypto assets.
