Your all-in-one resource for setting up, using, and understanding Trezor Bridge
Trezor Bridge is a communication interface that facilitates secure interaction between your Trezor hardware wallet and your web browser. Acting as a secure middle layer, it allows desktop applications and browser extensions to detect and interact with your device seamlessly. Unlike browser plugins, Trezor Bridge provides more stability and native communication with your Trezor device, especially when used with Trezor Suite or supported third-party apps.
Extensions can be limited by browser updates, permission restrictions, or security issues. Trezor Bridge operates outside the browser’s sandbox, ensuring consistent performance and fewer interruptions. It also improves cross-platform compatibility, allowing you to run the same workflow on macOS, Windows, and Linux.
Installing Trezor Bridge is a straightforward process. Visit the official Trezor Bridge download page, select your operating system, and follow the installer instructions. After installation, restart your browser and connect your Trezor device. Make sure no other Trezor-related apps (like outdated Chrome extensions) are running in parallel.
Trezor Bridge supports the following operating systems:
Trezor Suite is Trezor's official desktop wallet software. Once Bridge is installed, Trezor Suite automatically detects the hardware wallet. You can send, receive, exchange crypto, or manage accounts with minimal latency. The combination of Suite + Bridge ensures optimum security and feature coverage.
Trezor Bridge is signed and verified by SatoshiLabs. When installing, always check the authenticity of the installer. Avoid downloading from third-party sources. Bridge does not store any user data or private keys—it’s only a communication interface.
If your browser fails to recognize your Trezor, ensure that:
If problems persist, reinstall Bridge using the latest version. On Linux, make sure your user has permission to access USB devices by adding appropriate udev rules.
Developers can use the Bridge’s local API for custom wallet implementations. Communication occurs via localhost:21325. This allows integration with advanced DeFi tools, portfolio trackers, and payment systems. For technical documentation, consult the Trezor GitHub repository.
No. Trezor Bridge is designed for desktop systems. Mobile platforms typically use WebUSB or native integrations instead.
Yes. Chrome, Firefox, and Edge are fully compatible with Bridge. Just make sure the browser is restarted after installation.
Absolutely. Bridge is signed and maintained by SatoshiLabs. Always download from the official site to avoid tampered versions.
No. Trezor Bridge never accesses or stores your private keys. It simply passes encrypted communication between your device and apps.
Your funds are safe. Transactions are only confirmed once approved on the Trezor hardware screen. If the Bridge fails, restart it and reconnect.
