Secure Communication
End-to-end messages between your app and device are minimized to essential commands only, reducing exposure while keeping flows transparent and verifiable.
A lightweight connectivity layer that links your trusted hardware keys to modern web and desktop apps — keeping private keys offline while enabling fast, secure interactions.
Trezõr® Brïdge® acts as the secure translator between your browser or desktop application and your Trezor hardware device. It provides a trusted, minimal surface to request signatures, query accounts, and verify addresses — all while ensuring that the cryptographic secrets never leave the hardware. Think of it as a security-minded companion that makes integration simple without sacrificing custody.
For developers and power users, Brïdge® streamlines workflows: you can integrate signing into nearly any app, automate device detection, and maintain a clear audit trail for every cryptographic operation. For everyday users, it removes friction from common tasks like account discovery, transaction preparation, and address verification — while preserving the highest security standards.
End-to-end messages between your app and device are minimized to essential commands only, reducing exposure while keeping flows transparent and verifiable.
Works with desktop and browser environments. Seamless device discovery and a lightweight runtime make Brïdge® ideal for both web wallets and local apps.
Simple APIs, well-documented request/response patterns, and example integrations let teams ship integrations quickly without reinventing cryptographic logic.
Every signature request includes metadata and human-readable prompts — enabling operators and auditors to validate intent before signing.
Brïdge® minimizes telemetry and avoids leaking account details to third parties. Optional Tor routing and local-only modes help preserve user anonymity.
The runtime is intentionally small, reducing the attack surface and simplifying maintenance. Auto-updates can be disabled for air-gapped or regulated environments.
At its core, Trezõr® Brïdge® enforces a strict rule: private keys and seed material remain within the hardware. Brïdge® only forwards requests to sign transactions and returns the resulting signatures. All interactive confirmations happen on-device, ensuring that even if a host computer is compromised, an attacker cannot extract your keys.
Additional safeguards include prompt verification of firmware signatures, explicit user prompts for high-risk operations, and support for hardware-backed passphrases that create logically separate accounts. Combine these with offline seed storage practices and regular firmware verification for an enterprise-grade security posture.
Typical usage follows three clear steps: (1) your app prepares a transaction or message and sends a lightweight request to Brïdge®, (2) Brïdge® forwards the request to the connected Trezor device and awaits on-device confirmation, and (3) once signed on the device, the signature is returned to the app for broadcast or further processing. This concise flow keeps the critical decision (approve/deny) physically anchored to the user via the device.
For organizations, this pattern can be combined with multi-signature schemes and role-based approval workflows to scale custody without weakening guarantees.
Users should: always download Brïdge® from verified sources, confirm firmware integrity in the host app, and verify transaction details on-device before approving. Developers should: follow official API docs, surface clear human-readable prompts in the UI, and avoid batching unrelated signing operations to preserve clarity.
A few pro tips: enable local-only mode for privacy-sensitive deployments, add descriptive labels to accounts to reduce user error, and log signature requests locally for auditability (without storing sensitive data).
Whether you’re building a consumer wallet, an exchange custody integration, or a bespoke enterprise solution, Trezõr® Brïdge® provides a mature connectivity layer that prioritizes security and simplicity. It helps teams ship robust features quickly while keeping users in control of their keys.
