Meet Trézór Bridge and the Trézór App
Trézór Bridge is the connecting layer that makes the Trézór App possible — allowing secure hardware wallets to interact with modern applications without compromising private keys. The new Trézór App is designed around the idea that security should be effortless. It pairs clean design with advanced cryptographic protections so both newcomers and power users can manage assets confidently.
Seamless pairing
Pair your hardware device with the Trézór App via USB, Bluetooth, or WebUSB. Trézór Bridge handles session negotiation, while the app focuses on user experience.
On-device signing
All signing operations happen on the device. Trézór Bridge never transfers private keys off-device; instead it relays signed responses securely to the app.
Cross-platform
The Trézór App is available for desktop and mobile platforms. A web-first mode allows quick access without native installs, and the Bridge ensures consistent behavior across environments.
Privacy-preserving
Trézór Bridge minimizes metadata exposure. It uses ephemeral connections and allows users to restrict telemetry and analytics for maximum privacy.
Why this matters
Cryptocurrency security depends not only on robust hardware, but on how that hardware is used. The new Trézór App, enabled by Trézór Bridge, reduces room for user error with clear flows, address verification, and step-by-step confirmations. Whether you are sending funds, interacting with decentralized applications, or managing multiple accounts, the Bridge makes sure the device remains the ultimate authority for all sensitive operations.

Feature deep-dive
Trézór Bridge supports multiple communication channels, session scoping, and secure attestation. The Trézór App builds on these primitives to provide features like multi-account management, token discovery, built-in exchanges, and transaction templates. Below we cover key capabilities and recommended practices.
Secure pairing
Pairing uses a one-time session handshake with mutual verification. The device displays a pairing code you confirm on your host, ensuring a man-in-the-middle cannot silently intercept the connection.
Address verification and UX
When the app requests an address, that address is shown on the device’s screen for verification. Trézór Bridge additionally provides a checksum and context flags so the app can indicate when to show extra warnings (e.g., contract interactions).
Developer integrations
Developers can integrate with Trézór Bridge APIs to enable on-device approvals for their dApps. Documentation and SDKs are available to streamline secure integrations and to ensure best practices are followed.
Recovery & backup
The Trézór App provides guided recovery flows using standard seed phrases and supports passphrase-augmented hidden wallets. The Bridge is not involved in seed generation or storage — those operations remain strictly on-device.
