How It Works
Once installed, Trézór Bridge®™ runs in the background. When a dApp, Web3 wallet, or desktop wallet needs to sign or read public keys, the Bridge:
- Receives request from app
- Sends request securely to your hardware wallet
- Displays details on the device screen
- Waits for your manual approval
- Returns verified signature to the app
This guarantees your digital assets are protected even if your computer is compromised.
