Trezör® Bridge® is designed to be the secure, low-friction gateway between hardware wallets and the growing Web3 ecosystem. In this presentation-format page we’ll walk through what Bridge is, how it secures private keys and transactions, why it scales for teams and institutions, and how your users will interact with it in desktop and web environments.
Universal Compatibility
One integration to connect to multiple chains and wallets — built on open standards so dApps and services can plug in without repeated audits.
Hardware-anchored Security
Private keys never leave the device. Bridge proxies requests and signs transactions while enforcing user prompts and device verification steps.
Enterprise Controls
Role-based access, whitelisting, and audit logs for organizations that require governance and demonstrable compliance.
Seamless UX
From onboarding to transaction confirmation, Bridge provides clear, consistent user flows so onboarding friction is minimal and user confidence is high.
Problem Statement
Web3 adoption is slowed by fragmented wallet interfaces, inconsistent signing flows, and risk of private key exposure when users rely on web-only wallets. For projects building dApps, the engineering and security costs of supporting many wallet types and hardware devices can be prohibitive. Trezör® Bridge® solves this by providing a single, auditable layer that mediates all wallet interactions while maintaining the security guarantees of hardware keys.
How It Works — High Level Flow
Users physically pair their hardware wallet with Bridge using USB/Bluetooth and confirm a device fingerprint. Pairing generates a persistent, locally stored pairing token — the private key remains on-device.
Bridge establishes an encrypted session between the browser/dApp and the hardware device. Session keys are ephemeral and rotate frequently to reduce attack surface.
When a dApp requests a signature, Bridge validates the request origin, shows human-readable intent, and passes the transaction to the device for user confirmation.
All high-level events are logged locally (and optionally to a remote enterprise log) with cryptographic proofs that preserve user privacy while supporting compliance needs.
Security & Threat Model
Bridge assumes adversaries can control the host machine and the network. The only trusted element is the hardware wallet. To address threats we employ:
- Hardware Enforced Signing: Transactions are signed on-device only after the user visually verifies intent on the device screen.
- Session Key Rotation: Short-lived session keys reduce replay and interception risks.
- Origin Checking: Strict dApp origin and manifest verification prevents phishing-style request injection.
- Local-first Logs: Tamper-evident logs provide a traceable chain of custody without exposing private keys.
Developer Integration
Bridge provides a lightweight SDK, code snippets for common frameworks, and a playground for testing signature flows. Integration points include a JavaScript client, a REST admin API for enterprise features, and documentation with compliance checklists to speed audits.
Customer Benefits
Organizations and individual users gain peace of mind: reduced key-exposure risk, fewer support incidents, standardized UX across dApps, and faster integration time for product teams. The combined effect is higher user trust, lower operational risk, and accelerated adoption of Web3 services.
Conclusion
Trezör® Bridge® — Connect Your Web3 World Securely™ provides a single, secure, and UX-friendly bridge between hardware keys and the decentralized apps that depend on them. By keeping private keys on-device, enforcing clear user consent, and offering enterprise-grade controls, Bridge unlocks more of Web3 for more people and organizations. The platform is deliberately modular: integrate what you need, adopt what helps, and maintain the strongest possible security posture throughout the transaction lifecycle.
