Seamless and secure communication between your Trezor hardware wallet and web applications.
Trezor Bridge is the official communication software that allows your Trezor hardware wallet to interact with desktop and web applications securely. Developed by SatoshiLabs, the creators of the first hardware wallet, the Bridge ensures smooth, encrypted communication between your device and supported apps like Trezor Suite Web.
Without Trezor Bridge, browsers wouldn’t be able to recognize or communicate with your hardware wallet. The Bridge works silently in the background — connecting your Trezor device to supported wallet interfaces, verifying firmware updates, and ensuring every interaction is authenticated and secure.
In a world where phishing and malware are rampant, connecting a hardware wallet to the internet must be done with extreme caution. Trezor Bridge acts as a safe translator between your browser and your hardware wallet, keeping your private keys isolated from your computer and ensuring every request to your Trezor device is legitimate and user-approved.
When you connect your Trezor hardware wallet to your computer, the Bridge software runs as a background service that listens for requests from supported applications. When you log into Trezor Suite Web or another app that supports hardware wallets, the Bridge establishes a secure channel between your browser and your Trezor device.
Every action — such as verifying firmware, checking balances, or signing transactions — is verified on your Trezor device’s physical display. This prevents malicious software from initiating actions without your consent.
You can download and install the Bridge from the official Trezor website at trezor.io/bridge. Installation takes less than a minute:
Trezor Bridge supports the following operating systems:
Supported browsers include Google Chrome, Microsoft Edge, Brave, and other Chromium-based browsers that support WebUSB or WebHID.
The Trezor Suite App has both desktop and web versions. The desktop version communicates directly with your Trezor device, while the web version uses the Bridge to facilitate secure connections.
Once installed, the Bridge automatically runs in the background. There’s no need to launch or configure it manually — it simply ensures that whenever you open Trezor Suite Web, your wallet can be detected and accessed.
One of the biggest misconceptions about hardware wallets is that they must remain disconnected to stay safe. With Trezor Bridge, you can safely connect your device knowing that communication happens through verified, open-source code maintained by SatoshiLabs.
If your Trezor device isn’t detected after installing Bridge, try these steps:
Modern browsers now support WebUSB and WebHID, which can connect directly to hardware wallets without additional software. However, Trezor Bridge remains the most stable and compatible solution, particularly for systems or browsers where WebUSB isn’t supported.
SatoshiLabs continues to maintain and update Bridge for maximum compatibility across devices, ensuring older systems and less common configurations remain supported.
Like all Trezor software, the Bridge is completely open source. Its code is publicly available for audit, meaning security researchers and the community can independently verify its integrity. This commitment to transparency has made Trezor one of the most trusted brands in the crypto security space.
Updates to Trezor Bridge include important bug fixes, improved browser compatibility, and performance enhancements. Running the latest version ensures you enjoy a stable and secure connection to your wallet at all times.
The Trezor Bridge is the backbone of secure communication between your hardware wallet and the online world. Whether you’re managing your Bitcoin holdings, signing Ethereum transactions, or simply checking balances, Bridge ensures every action is safe, verified, and fully under your control.
Always download Trezor Bridge from the official website — trezor.io/bridge — to avoid malicious versions or phishing attacks. Combined with Trezor Suite and your hardware wallet, it forms a complete ecosystem for secure, transparent, and private crypto management.
