Introduction

Project Name: Cypherock X1 - Sia Network Integration

Name of the organization or individual submitting the proposal: Cypherock

Describe your project.

This project is the complete, native integration of the Sia network into the Cypherock X1 hardware wallet and our companion cySync desktop application.

Cypherock X1 is a market-ready hardware wallet that fundamentally improves on traditional self-custody by eliminating the single point of failure of a seed phrase. It uses a 2-of-5 Shamir’s Secret Sharing scheme to shard a user’s private key across one hardware device and four tamper-proof NFC cards. This provides unparalleled resilience against loss, theft, and damage.

The scope of this project is to deliver an end-to-end Sia hardware wallet solution:

  1. Firmware Integration: Implement Sia’s cryptographic primitives on the Cypherock X1’s secure element, enabling on-device key generation, address verification, and transaction signing.

  2. Software Integration: Add full Siacoin (SC) support to our cySync desktop application. This will provide users with a complete GUI for managing their Sia assets—checking balances, sending, and receiving—all from a single, official application.

This creates a unified, first-class user experience, a significant improvement over the current fragmented ecosystem where users of other hardware wallets (like Ledger) must rely on third-party web wallets (like Sia Central’s web wallet) for any interaction, as their native companion apps lack Sia support.

Who benefits from your project?

  • Existing Sia Users (Hosts, Renters, Holders): Gain access to a next-generation security model to protect their SC holdings and operational keys without the single point of failure of a seed phrase.

  • New Users to the Sia Ecosystem: Cypherock’s existing and future user base will have a seamless, one-click way to start using Sia, directly driving adoption for the network.

  • The Sia Foundation and Ecosystem: The integration of a premium hardware wallet with a fully supported software suite enhances the perceived security and maturity of the Sia network, making it more attractive to developers, partners, and institutional users.

How does the project serve the Foundation’s mission of user-owned data?

The Foundation’s mission of user-owned data is fundamentally reliant on the user’s ability to securely control their private keys.
Our project directly strengthens this mission by providing the most resilient method for users to own and control their keys. By eliminating the single point of failure of a seed phrase, Cypherock makes user ownership of data on Sia radically more secure and resistant to both physical loss and remote attacks. A user can lose up to three of their five wallet components and still retain ownership of their data and assets. This level of security is essential for the long-term vision of a truly user-owned internet.

Hello, can you please clarify why you are referencing siad in your research as opposed to the core/coreutils libraries used now for Sia v2? That stood out a bit to me and wanted to verify there was no mixup in your research.

Also be aware your generally expected to follow About the Grants category - #8 as a report template and use a Github repo for code and documents.

Kudos.

Final Milestone November Report: Testing & Launch

What progress was made on your grant this month?

We are pleased to report the successful completion of our final milestone, “Testing & Launch,” and the conclusion of the Cypherock X1 grant project. Our work this month focused on transitioning from beta to a full public release, ensuring a polished and reliable product for the entire Sia community.

  • Successfully released the new firmware and cySync software with full Sia support to the public.

  • Published a joint announcement and a detailed blog post in collaboration with the Sia Foundation to officially launch the integration.

  • Created and released comprehensive user guides, including a step-by-step video tutorial, to ensure a smooth onboarding process for all users.

  • Successfully met all deliverables for the final project milestone, delivering a fully integrated, market-ready Sia hardware wallet solution to the community.

Detail tasks worked on this month per milestone with the appropriate links:

Milestone Task Link(s) Additional Notes
Testing & Launch Public release of firmware and software. Link to GitHub Release Page for cySync app
Link to GitHub Release Page for firmware		 Now live and available for all users via the official cySync application.

Summarize any problems that you ran into this month and how you’ll be solving them.
The launch was executed smoothly, and the challenges encountered were primarily logistical rather than technical.

  • Challenge: Community Beta Feedback Integration

    • Description: During the final beta phase, community testers provided valuable feedback on the user flow and some minor UI elements.

    • Solution: We dedicated a short development cycle to incorporate this feedback, addressing several minor UI/UX inconsistencies before the final release. This resulted in a more polished and intuitive final product for the public.

  • Challenge: Coordinated Launch Timing

    • Description: Coordinating the simultaneous release of the cySync app, X1 firmware, social posts and video tutorials across Cypherock channels required careful planning.

    • Solution: We maintained close communication with the Sia Foundation team to align on a precise launch schedule, ensuring a unified and impactful announcement.

What will you be working on next month?
As the grant project is now complete, our focus will shift from development to long-term support, maintenance and marketing collaboration.

  • Community Support: We will actively monitor the Sia Forum, Discord, and our own support channels to provide assistance and gather feedback from new users of the integration.

  • Maintenance & Bug Fixes: Our engineering team will continue to maintain the integration, prioritizing any bugs that may be discovered by the community post-launch.

  • Future Enhancements: We will collect and evaluate user feedback to explore potential future enhancements.

  • Marketing: We are interested in doing more cross-marketing with Sia Foundation across all channels.
