Trezor Bridge is the official connection layer that lets your Trezor hardware wallet talk to desktop apps and web wallets. Learn how to install, use and troubleshoot Trezor Bridge for a smooth crypto experience.
Trezor Bridge is the small software service that runs on your computer and lets websites and desktop applications communicate with your Trezor device. When you connect your Trezor hardware wallet, the trezor bridge (sometimes written as Trezor/Bridge) handles secure USB communication so your browser-based wallets and desktop clients can detect and interact with the device without exposing private keys.
Whether you're using a web wallet or a local application, installing Trezor Bridge is usually the first required step. Many web-based crypto apps will prompt you to download or update trezor bridge if it's missing or out of date.
Tip: If a website says “Bridge not found,” try reinstalling the latest Trezor Bridge or restarting your browser after installation.
Trezor Bridge does not access or store your private keys. The Trezor device keeps all keys isolated on the hardware. Trezor Bridge simply forwards encrypted requests from applications to the device. Always download trezor bridge from the official source and verify checksums if provided.
Device not recognized: Ensure Trezor Bridge is installed and that your OS recognizes USB devices. Try a different USB cable or port. Rebooting the system can clear USB driver states.
Browser blocked access: Some browsers require explicit permission or need to be restarted after installing Trezor/Bridge. Disable conflicting extensions or try a privacy profile that doesn't block WebUSB.
Update problems: If firmware or software updates fail, confirm you have the latest Trezor Bridge, the latest desktop wallet, and follow the device prompts exactly. Reinstalling Trezor Bridge often resolves update stalls.
Trezor Bridge is a background communication service that connects your device to applications. Trezor Suite is the desktop application that provides a full user interface for account management. Many users install trezor bridge so web wallets and Suite can talk to their device.
Yes — when downloaded from the official Trezor site. Trezor Bridge acts only as a communication layer; private keys remain on the hardware. Always verify downloads and avoid third-party mirrors.
Reinstall Trezor Bridge, restart your browser, check USB connections, and ensure the website is allowed to access the device. If problems persist, try another browser or temporarily disable privacy extensions that block device access.
Mobile platforms typically use direct Bluetooth (for compatible devices) or specific mobile apps. Trezor Bridge is primarily a desktop/web solution for connecting USB-attached Trezor devices.
Keep Trezor Bridge updated to the latest stable release. Updates often include compatibility improvements, security patches, and better device support—important when using new web interfaces or desktop wallets.
