Welcome — what is Trézór Bridge and the new app?
Trézór Bridge is the background connector that enables seamless, secure communication between the Trézór hardware wallet and the desktop/web application. Alongside the Bridge we’re introducing the new Trézór App — a refreshed desktop and web interface built for clarity, faster workflows, and better privacy controls. The Bridge handles device discovery, authenticated messaging, and encrypted transports while the app focuses on UX: portfolio visibility, transaction construction, and on-device verification flows.
Key features of the new Trézór App
- Unified dashboard: consolidated balances, recent activity, and actionable alerts in a single view.
- Improved device pairing: simplified pairing using Trézór Bridge, with clear prompts and trusted-origin checks.
- Privacy controls: optional full-node integration, selective telemetry opt-out, and explicit network configuration.
- On-device verification UI: richer human-readable transaction previews on the device for both simple transfers and contract interactions.
- Developer-friendly: PSBT support, standardized derivation paths, and enhanced observability for integrations.
Installation & quick start
To get started, download Trézór Bridge and the Trézór App from the official website. Install the Bridge first — it runs as a small background service that exposes a secure local endpoint for the app. Once Bridge is installed, launch the Trézór App, connect your hardware wallet, and follow the guided pairing flow. The app detects the Bridge automatically and prompts you to authorize the connection on both the device and the app.
Tip: Always download installers from the official Trézór domain and verify signatures or checksums when available.
Security model — what stays on-device
The Trézór security model centers on keeping private keys inside the hardware wallet. Trézór Bridge only facilitates authenticated messaging — it does not handle or store private keys. All signing operations occur on-device, and the new app emphasizes on-device human-readable confirmations. The Bridge uses encrypted channels (TLS-like) for local IPC, and it restricts connections to whitelisted origins to prevent unauthorized apps from requesting actions.
Privacy & network options
Privacy was a key goal for the new app. Users can:
- Point the app to their own full node for blockchain queries.
- Opt out of telemetry and analytics.
- Review and control RPC endpoints used by DApps integrated through the app.
Advanced workflows
Power users can leverage advanced flows like PSBT signing, multisig coordination, and air-gapped signing using the Trézór App’s export/import tools. The app provides clear instructions for each step to reduce human error and integrates integrity checks to ensure transactions aren’t tampered with during transit between devices or systems.
Migration & compatibility
Existing users will find migration paths from the older app and Bridge versions. The new software respects existing recovery seeds and account derivations. During the first launch, the app will offer to import known accounts and settings; users retain control and can opt to set up accounts anew. Backwards compatibility for commonly used derivation paths, token standards, and multisig configurations is included to ease transitions.
Troubleshooting & support
If the Bridge doesn’t detect a device, check USB cable health and system permissions. On some operating systems you may need to approve the background service during installation. Firewall or antivirus software can interfere with local IPC — temporarily whitelist the Bridge if needed. For persistent issues, consult the official support docs or export diagnostics from the app for community or support review (do NOT share recovery seeds).
FAQ
Do I still need a hardware wallet?
Yes. The Bridge and App complement your hardware wallet — private keys remain protected on the device at all times.
Can I run the app without Trézór Bridge?
The app requires Bridge (or a compatible communication layer) to interact with the hardware wallet on most desktop environments. Mobile and future browser-native flows may differ.
Conclusion
Trézór Bridge and the new Trézór App together provide a modern, privacy-conscious, and developer-friendly platform for interacting with hardware wallets. By separating the transport (Bridge) from the user interface (App), we maintain a robust security boundary while delivering improved usability and advanced features for both casual users and power operators.
