Trezor Bridge — Connect Your Wallet to Browsers
Trezor Bridge is the official communication layer that links your Trezor hardware wallet to supported web browsers. Without it, your browser cannot recognize or communicate with your Trezor device. Bridge ensures secure, reliable, and uninterrupted interaction, enabling users to manage cryptocurrencies, sign transactions, and access web-based wallet tools without compromising privacy or security.
If you use the Trezor Suite Web App or any browser-based third-party crypto services, Trezor Bridge is the essential tool that makes everything work smoothly.
What Is Trezor Bridge?
Trezor Bridge is a lightweight application that runs on your computer and allows browsers to detect and communicate with your Trezor hardware wallet. It replaces outdated browser plugins and ensures compatibility across modern operating systems and browsers.
Its primary role is simple but vital:
✅ Let the browser recognize your Trezor
✅ Enable secure, encrypted data transmission
✅ Serve as a stable, system-level connector
The Bridge does not access private keys or personal data — it only facilitates communication.
Why Trezor Bridge Is Necessary
Modern browsers no longer support the old communication protocols that hardware wallets once used. This is why many users see “Trezor not detected” unless Bridge is installed.
Trezor Bridge solves the issue by:
Creating a secure communication link
Ensuring compatibility with browser updates
Maintaining consistent performance on all major operating systems
Supporting both Trezor Suite Web and external wallet integrations
Without Bridge, your browser-based crypto tools simply won’t function with your hardware wallet.
How Trezor Bridge Works Behind the Scenes
Trezor Bridge quietly runs in the background and performs three core functions:
1. Device Detection
When you open a web app like Trezor Suite Web, Bridge alerts the browser that a Trezor device is connected.
2. Secure Communication Layer
All sensitive tasks (PIN entry, passphrase, signing) happen exclusively on the hardware wallet — not in the browser.
3. Universal Compatibility
Bridge bypasses browser restrictions, ensuring everything works smoothly even after major browser updates.
It’s lightweight, fast, and requires no manual configuration.
