Trézór Bridge is the official background service by SatoshiLabs that lets your browser talk to your Trezor—without risky extensions. Install once, and every supported web app can request verified actions on your hardware wallet, while your private keys remain offline. It’s the invisible layer that makes everyday crypto management stable, fast, and predictable.
Unlike browser add‑ons that can break or get compromised, Trézór Bridge runs locally and communicates directly with your device. No extra permissions, no shady middlemen—just a stable channel that keeps sensitive operations on your hardware wallet where they belong.
Bridge avoids constant API churn of browser extension platforms. By living on your machine and exposing a controlled interface, it reduces breakage when browsers update. For everyday users, that means fewer surprises and more time focusing on what matters—managing assets safely.
Your private keys never leave your Trezor. Bridge simply forwards requests for actions (like address confirmations or transaction signing) to your device, where you physically approve them. Malware in the browser cannot silently sign on your behalf.
Windows, macOS, and Linux are supported with a consistent experience. Install once and use it with Trezor Suite and compatible third‑party web apps without fiddling with separate drivers or one‑off hacks.
You only need to do this once. After installation, Bridge launches automatically at startup and quietly handles communication whenever a site requests your Trezor.
Visit trezor.io/bridge. Always verify the domain and certificate to avoid phishing. The page will offer installers for Windows, macOS, and Linux.
Tip: bookmark the page for future updates. Bridge auto‑updates, but it’s good to know where official announcements live.
Bridge does not store wallets, seed phrases, or secrets. It simply orchestrates a conversation: the browser asks for something, Bridge relays that to your Trezor, and you confirm on the device. Transaction signing happens inside the secure hardware—never in the operating system, never in a web tab. Even if a site is malicious, it cannot extract your private keys because those keys never touch the computer.
Because you approve every action physically, Bridge helps defeat common phishing tricks. A spoofed website cannot silently authorize a transaction; your device will still display the recipient and amount, and you can reject it. This human‑in‑the‑loop design is what makes hardware wallets so powerful.
To stay safe, keep your device firmware and Bridge up to date, verify download sources, and never type your recovery seed on a computer. If a site asks for your seed phrase, it is not legitimate.
From automatic updates to a clean local interface, Trézór Bridge balances ease of use with strong security defaults. These highlights give you a quick sense of what’s built‑in.
Skip the extension roulette. Bridge avoids the permission creep, tracking risks, and sudden deprecations that plague many add‑ons. Your connection remains consistent across updates.
Once installed, Bridge launches with your system so it’s ready when you are. There’s nothing extra to open—just plug your device and use your favorite app.
Bridge is designed to be unobtrusive. It consumes minimal CPU and memory, keeping your workstation responsive even during heavy multitasking.
Backed by the creators of Trezor, Bridge receives timely updates, compatibility fixes, and security hardening informed by years of wallet R&D.
Use Trezor Suite for portfolio overviews, account management, and coin‑specific features. Bridge ensures Suite and supported web apps can access your device when needed.
When a site needs your device, you’ll see clear prompts and must approve on the hardware. This clarity reduces mistakes, especially for newcomers.
