As Web3 grows, the interfaces we use evolve rapidly: browser apps, desktop suites, and decentralized applications. Trezör® Bridge® is the official local connector that ensures your hardware wallet communicates with these interfaces reliably — without exposing private keys or relaxing on-device confirmations. It’s the secure, predictable middle layer between your Trezör device and the apps you trust.
Trezör® Bridge® translates requests from web apps or desktop wallets into USB or HID commands your Trezör hardware understands. When a wallet requests an action — such as showing an address or signing a transaction — Bridge forwards the request locally. The Trezör device validates and prompts you to confirm; only then is the operation completed. Bridge never has access to your recovery seed or private keys.
Always verify the download source. If an installer provides a checksum or signature, verify it before running the file.

rules so non-root users can access the device.Trezör® Bridge® is built around a few non-negotiable principles: least privilege, local-only access, and user-intent. Bridge acts solely as a translator — it does not attempt to access or export secrets, nor does it enable remote control. All sensitive operations require physical confirmation on the Trezör device itself. This reduces attack surface and keeps critical operations in the secure environment of the hardware wallet.
Bridge does not collect or transmit your transaction history or private keys. However, wallet apps you connect to may interact with external nodes or API providers which can see addresses and balances. If privacy is a priority, use privacy-preserving nodes or run your own node when possible.
Developers should use Trezör Connect
or the officially documented API to interact with Bridge. The library handles session negotiation and user prompts; it avoids direct USB handling so your app remains cross-platform. Respect user confirmations, never auto-approve device prompts, and test across platforms to catch edge-case USB behavior.
Web standards like WebHID and WebUSB are making it easier for browsers to talk to devices directly. While promising, these standards vary across browsers and OS versions. Trezör® Bridge® remains the recommended connector for users and developers seeking a consistent, supported experience across the wide range of environments Web3 apps run in today.
