Connect your Trezor® hardware wallet to Trezor Suite® seamlessly and securely with Trezor Bridge — the official communication layer built for your protection.
Trezor Bridge is a lightweight software component that enables communication between your Trezor® hardware wallet and Trezor Suite®, the official management interface for your crypto assets. Without this essential bridge, your browser or desktop app would not be able to detect or communicate with your physical device. Think of it as a secure translator that connects your hardware wallet to your computer, ensuring smooth, encrypted, and authenticated data exchange.
Released by SatoshiLabs, the creator of Trezor®, Trezor Bridge was designed with one goal in mind — to make connecting your hardware wallet to your computer effortless while maintaining the highest security standards possible. Whether you use Trezor Model One or Trezor Model T, the Bridge guarantees that no unauthorized third party can intercept or modify communication between your device and the Trezor Suite® app.
Your Trezor® hardware wallet is built for maximum security. However, it needs a reliable way to connect to your computer’s applications. Browsers and operating systems have limitations on direct hardware communication. Trezor Bridge solves this by creating a secure channel through which Trezor Suite® can access your device.
Without it, Trezor Suite® would not recognize your hardware wallet properly, leading to connectivity issues or unresponsive sessions. Trezor Bridge ensures that every command, every transaction, and every message exchanged between your wallet and computer happens in a trusted, encrypted environment.
When installed on your computer, Trezor Bridge runs quietly in the background. It listens for communication requests from Trezor Suite® and securely forwards them to your connected hardware wallet through USB.
Every request — whether for account access, transaction confirmation, or firmware update — is encrypted and verified. The Bridge acts as a digital gatekeeper, ensuring that only the official Trezor Suite® client can communicate with your wallet.
Installing Trezor Bridge takes just a few minutes. Follow these simple steps:
The Bridge runs automatically — there is no need to launch it manually. You can confirm it’s active by checking your system tray or task manager.
Trezor Bridge is compatible with all major operating systems, including:
Most modern browsers such as Chrome, Firefox, Brave, and Edge support Bridge-based communication. For advanced users, Trezor Suite® desktop app provides a more integrated and private connection method, eliminating browser dependency altogether.
Security is at the heart of every Trezor product, and the Bridge is no exception. The software uses encrypted local communication channels and strict device authentication to ensure that no third-party software can eavesdrop or inject malicious code.
Furthermore, Trezor Bridge does not store, transmit, or log any sensitive data such as your private keys or seed phrases. All cryptographic operations occur exclusively on the hardware wallet itself. The Bridge merely acts as a messenger, transferring approved data between your device and the Trezor Suite® interface.
To maintain compatibility with new firmware and software versions, it’s important to keep your Trezor Bridge up to date. Trezor Suite® will notify you when an update is available, or you can manually check at trezor.io/bridge.
Updating is straightforward — simply download the latest version and install it over your existing one. Your settings and data will remain untouched.
Sometimes users may encounter connection issues between Trezor Suite® and their device. Here are quick solutions:
In most cases, reinstalling the Bridge or updating your Trezor Suite® resolves the problem. If issues persist, the Trezor Support Center offers detailed troubleshooting guides.
Trezor Bridge is open-source, and its codebase is available on GitHub. Developers can use it to create custom integrations or build wallet management tools that communicate directly with Trezor® devices.
The Bridge supports a local HTTP interface and JSON-RPC protocol, allowing advanced users to send commands to their device securely. However, using these features requires caution — only trusted software should interact with your hardware wallet.
In earlier versions of browsers, direct USB access was handled by plugins such as WebUSB. However, many browsers have deprecated plugin-based communication due to security concerns. Trezor Bridge replaces these legacy methods with a safer, modern solution.
Unlike browser extensions, the Bridge runs at the system level, independent of your browser. This means fewer compatibility issues, stronger privacy, and consistent behavior across all browsers.
Following these practices ensures that your communication between computer and wallet remains authentic, private, and tamper-proof.
In the world of digital assets, self-custody is the foundation of financial independence. Trezor Bridge supports this mission by acting as the invisible yet vital connector between your offline wallet and the online world.
It enables you to verify, approve, and broadcast transactions safely — without ever exposing your private keys. The simplicity of its design hides the complex cryptographic protections that make this possible.
Trezor Bridge is not just a background process — it’s the secure gateway that empowers your Trezor® hardware wallet to communicate confidently with Trezor Suite®. From initial setup to daily use, it ensures every interaction is protected, private, and frictionless.
Whether you’re a new crypto investor or an experienced holder, Trezor Bridge offers peace of mind — knowing that your digital assets are always in your control, connected through the safest path possible.
