Trezõr brïdge® | Connect Your Web3 World Securely™

1. Executive summary

What is Trezõr brïdge®?

Trezõr brïdge® refers to the set of official integration components and apps that let users connect their Trezor hardware wallet to web and desktop applications for key operations — viewing addresses, signing transactions, and authorizing actions — while keeping private keys offline. It prioritizes user consent, attestation, and explicit verification flows so that signing remains a user-approved, device-side action.

2. Core benefits

Security

Hardware-backed signing removes private-key exposure from potentially compromised hosts. The device displays transaction details and requires physical confirmation for critical operations.

Interoperability

Integration libraries and protocols (e.g., Trezor Connect) provide standardized API endpoints and popup flows so third-party wallets, dApps, and exchanges can interact with Trezor devices reliably.

3. How it works — high level

Connection flow

Typical flow: app requests public key / signing → user selects device in popup → the device displays human-readable intent → user confirms on device → signed payload returns to the app. This model reduces attack surface by ensuring sensitive approval happens on the hardware itself.

Trezor Connect / Suite

Developers integrate a client SDK (Trezor Connect) or rely on official Suite functionality to host the trusted popup and orchestrate secure messaging between web apps and the device. The project provides both developer docs and production releases for safe integration.

4. Best practices for integrators

Use official libraries

Always use the official SDKs and follow the published integration documentation. Avoid third-party reverse-engineered implementations that bypass official checks and UIs.

Verify signatures & display integrity

Validate returned signatures server-side where applicable and mirror human-readable transaction details within your UI so users can cross-check what appears on the device.

Fallbacks & UX

Provide robust handling for disconnects, user cancellations, and software updates. If a standalone bridge client is deprecated in favor of embedded Suite functionality, guide users to update to the recommended flow (see official guidance).

5. Adoption checklist (technical + user)

• Integrate official Connect SDK and test in staging.
• Show transaction previews that match device text exactly.
• Implement signature verification and nonce checks.
• Provide clear instructions for new users (install Suite or mobile app).
• Monitor for SDK updates and revoke deprecated flows.

6. Migration note

Deprecation of standalone Bridge

The vendor has moved away from maintaining a separate standalone "Bridge" installer in favor of integrated Suite and web flows. Integrators should follow the official migration guidance and uninstall legacy Bridge installations when needed to ensure compatibility and security.

7. Closing / call to action

Secure by design

Bringing hardware-backed approvals into your Web3 flows offers a materially stronger security posture while preserving user ownership. Start with official SDKs, test thoroughly, and provide clear on-device confirmation instructions for the best user experience.
