Hardware Wallet Bridge — Secure Connection (Template)

Seamless, private, and resilient bridging between desktop/browser and hardware wallets.

A dependable bridge for your hardware wallet — built for security and clarity

This template describes a privacy-respecting hardware wallet bridge — a local agent that creates a secure channel between your desktop or browser and your hardware device. The bridge handles discovery, pairing, hardware-level signing, and transport security while keeping private keys isolated on the device. Use this page as a starting point for describing technical benefits and user-facing safety flows without presenting it as an official product page.

Secure Pairing
Certificate-backed pairing workflows and one-time pairing codes to prevent accidental connections.
Local-only Agent
Runs on the user’s computer with minimal external dependencies, reducing attack surface.
Transaction Signing
Clear transaction previews, domain-bound signing, and on-device confirmation for safety.
Cross-platform
Support for Windows, macOS, Linux and modern browsers via secure native messaging or WebUSB/WebHID adapters.

For site owners: present precise setup instructions, show screenshots of pairing flows, and provide downloads signed with a verifiable code signing certificate. Ensure the installer is code-signed and the download page explicitly links to checksums and verification guides so users can verify authenticity.

Design principles & security commitments

Security-first design means the bridge never exposes private keys to the host environment. All sensitive operations are performed on the hardware device, and the bridge’s role is to carry signed requests and present clear, auditable dialogs. Implement well-defined permission prompts, limit long-lived sessions, and provide a revocation mechanism in the event of suspicious activity.

User-friendly flows

A great bridge balances security with usability: simple device discovery, a short pairing sequence, and contextual help during signing. Using clear language and progressive disclosure helps users understand risks without power-law jargon. Accessibility matters — support keyboard use, screen readers, and high contrast modes.

Developer & integrator checklist

  • Ship signed installers and provide checksums.
  • Document native messaging channels and WebUSB/WebHID fallbacks.
  • Offer offline verification instructions and reproducible builds where possible.
  • Provide an API for integrators with stable versioning and clear migration notes.

Privacy and telemetry

Respect user privacy: avoid collecting wallet addresses, transaction metadata, or IP-linked telemetry by default. If telemetry is offered, make it opt-in and explain exactly what is collected and why. Offer accessible controls to view, export, and delete any permitted data.

Finally, include a public security policy and responsible disclosure contact so researchers can report issues, and publish a changelog for users to verify fixes.
