Trezör® Bridge® — Connect Your Web3 World Securely™

A comprehensive, modern, and security-focused guide explaining how Trezör® Bridge® acts as a critical connection layer between your hardware wallet and the decentralized web. This page is designed to inform, educate, and build confidence for users navigating the evolving Web3 ecosystem.

Foundation

Understanding Trezör® Bridge®

Trezör® Bridge® is a lightweight communication layer that allows supported web browsers to interact seamlessly with Trezör® hardware wallets. It eliminates the need for outdated browser plugins while preserving a strong security model rooted in hardware-level protection.

In the modern Web3 landscape, users expect instant, secure, and transparent interactions with decentralized applications. Trezör® Bridge® fulfills this expectation by acting as a trusted intermediary that never compromises private key isolation.

Unlike software-only wallet connectors, Trezör® Bridge® ensures that cryptographic operations are executed inside the hardware wallet itself. The bridge merely transmits signed data, not sensitive secrets.

Design

Technical Architecture

The architecture of Trezör® Bridge® is intentionally minimalistic. It is designed to reduce the attack surface while maintaining high compatibility across platforms and browsers.

Local Service Layer

Runs as a background service on the user’s operating system, listening only to authorized requests from supported browsers.

Browser Communication

Uses secure, well-defined APIs to enable communication without exposing wallet internals.

Device Isolation

Ensures that all sensitive cryptographic actions remain confined to the hardware wallet.

Permission Control

Each request requires explicit user approval on the physical device, reinforcing trust.

Protection

Security Principles

Security is the cornerstone of Trezör® Bridge®. Every design decision prioritizes user sovereignty and resilience against both remote and physical threats.

Hardware Key Isolation

Core Principle

Private keys never leave the hardware wallet. The bridge cannot read, export, or duplicate sensitive material.

User Verification

Human-in-the-loop

All transactions must be confirmed on the device screen, preventing silent or hidden approvals.

Open Security Model

Transparency

The design philosophy emphasizes auditable behavior and predictable communication flows.
