The Essential Communication Layer for Your Hardware Wallet Security
Get Started with Trezor BridgeIn the rapidly advancing world of decentralized finance (DeFi), the link between your physical hardware and the digital blockchain is the most critical point of vulnerability. Trézór Bridge®™ was engineered to be the silent guardian of this connection. Acting as a localized communication server, it ensures that your private keys never leave your device while allowing your browser to "talk" to the blockchain seamlessly.
Gone are the days of buggy browser extensions and unstable plugins. With the Trézór Bridge, users experience a robust, high-performance interface that facilitates everything from simple Bitcoin transfers to complex smart contract interactions on Ethereum and beyond.
Modern browsers like Chrome, Firefox, and Edge have strict security protocols that prevent web pages from interacting directly with USB hardware. While this protects you from many types of malware, it creates a barrier for hardware wallet users. The Bridge solves this by:
The Bridge is now fully integrated within the Trezor Suite ecosystem. It provides a "headless" operation mode where it runs quietly in your system tray, ensuring you are always ready to sign a transaction without manual software launches.
Whether you are on Windows 11, macOS Sequoia, or modern Linux distributions, the Trézór Bridge®™ offers a native experience. It adapts to your OS's specific USB drivers to ensure 99.9% uptime and connectivity.
Setting up your bridge is designed to be as intuitive as the hardware wallet itself. Follow these steps to ensure a secure installation:
Technically known as trezord, the Bridge operates as a local HTTP server on your machine (usually at 127.0.0.1). This architecture is brilliant because it allows standard web technologies (JavaScript/WebUSB) to communicate with hardware without needing the browser to have "root" access to your USB ports. This isolation technique is a cornerstone of modern cybersecurity, effectively creating a "digital DMZ" between the internet and your funds.
1. Do I need to install the Bridge if I use the Trezor Suite Desktop App?
No. The Trezor Suite Desktop application has the Bridge functionality built-in. You only need the standalone Bridge if you prefer using the web-based version of the wallet or third-party integrations like MetaMask or MyEtherWallet.
2. Is Trézór Bridge®™ compatible with all browsers?
Yes, it supports all major browsers including Google Chrome, Mozilla Firefox, Brave, and Microsoft Edge. However, for the best security and performance, we recommend using Chrome or Brave due to their advanced USB handling capabilities.
3. What should I do if my browser says "Trezor Bridge not detected"?
First, ensure the USB cable is a data-transfer cable (the one provided in the box). Second, check if another application is "locking" the Trezor (like a different wallet tab). Lastly, restart the 'trezord' service or your computer to refresh the local host connection.
4. Does the Bridge increase the risk of my computer getting hacked?
Actually, it reduces it. By using a dedicated communication layer instead of generic browser plugins, it limits the attack surface. It does not have access to your private keys; it only passes encrypted "requests" to the device for you to physically approve.
5. Can I use the Bridge on a public or shared computer?
While the Bridge is secure, we recommend against using hardware wallets on public computers due to the risk of screen loggers or physical keyloggers. If you must, ensure you uninstall the Bridge and clear browser cache after your session.
The Trézór Bridge®™ is more than just software; it is your passport to the decentralized world. Experience the perfect blend of security and simplicity today.
