Executive summary 

A Silicon Valley company developing a next-generation security chipset faced a critical challenge: with their hardware still two years from production, they needed a way to demonstrate the product’s value to early customers and partners. Regen Tech stepped in to design and develop a full-featured MPC software platform that emulated the chipset’s multi-party computation (MPC) capabilities. Our solution allowed the client to accelerate market engagement, strengthen product strategy, and gather critical feedback well before hardware release. 

Background 

Our client, a Silicon Valley innovator at the intersection of chipset engineering, cryptography, and digital asset security, was building a revolutionary hardware solution for private key protection. Their architecture, based on threshold-based multi-party computation (MPC), was designed to eliminate single points of failure by ensuring that private keys were never fully constructed or stored on any single device. However, with the hardware roadmap extending two years into the future, the company faced an urgent need to validate its vision and build traction. 

The challenge 

Without something tangible to showcase to customers and partners, the client risked losing momentum. They needed a secure, flexible, and realistic software counterpart to the hardware that could function in real-world conditions. Their ideal solution would need to support demos, partner integrations, and iterative development, all while mirroring the core logic of the future chipset. 

Regen Tech stepped in with a strategy to transform this delay into an opportunity for early innovation. 

Our approach 

Regen Tech, we followed our 4D methodology: Diagnose, Define, Develop, Deploy to ensure the project moved from problem to solution with clarity and precision. 

Diagnose: We collaborated with the client to understand hardware design, cryptographic goals, market objectives, and partner expectations. 

Define: We scoped a modular MPC software platform that could simulate the core security functions of the chipset and adapt to future changes. This included authentication, signing policy enforcement, and secure messaging capabilities. 

• A multi-platform MPC SDK supporting mobile, web, and native environments, using secure threshold signature schemes. 

• A mobile crypto wallet app, acting as one MPC party, with secure passkey login, dApp interaction, and creative tools. 

• A tamper-evident backend with blockchain anchoring and verifiable storage for auditability and policy coordination. 

Deploy: We released a 2-of-2 configuration first, followed by a 2-of-3 proof of concept. The next phase includes support for t-of-n configurations and broader device coverage across mobile, cloud, browser extension, and hardware. 

This was not just a proof of concept. It was a production-ready, secure cryptographic infrastructure maintained by a multidisciplinary team distributed across time zones. 

Implementation challenges and solutions 

Reproducing a hardware-grade security model in software posed several critical challenges: 

• Performance vs. fidelity: We fine-tuned cryptographic performance to match the security guarantees of the chipset, without compromising UX. 

• Cross-platform consistency: Our CI/CD infrastructure and automated test suites ensured SDK stability across mobile, browser, and embedded systems. 

• Index management for multi-chain wallets: We created dynamic, conflict-free indexing logic that maintained consistency for both multi- and single-chain wallet setups. 

• Flexible group design: Our MPC group model allowed multiple users and devices to participate in signing workflows without tying group identity to any individual account. 

Through architectural rigor, close coordination, and a focus on usability, we delivered a scalable and secure system fit for future growth. 

Results and anticipated impact 

As of June 2025, we successfully released a 2-of-3 proof of concept for the client. This milestone demonstrated threshold signing functionality across three distinct MPC parties: Mobile, Cloud, and Active Card. 

This release validated the system’s multi-device coordination, paving the way for real-world demonstrations, partner showcases, and security testing. It also provided valuable insights into user experience, operational readiness, and partner integration requirements. 

Next, we will expand the system to support more complex t-of-n configurations, further enhancing policy flexibility for enterprise scenarios. By the time the hardware reaches production, the software layer will already be proven and deployed, a powerful advantage for customer trust and go-to-market speed.

Conclusion 

At Regen Tech, we build more than software; we build secure, scalable paths to market. Our collaboration with this Silicon Valley innovator turned a hardware delay into a launch opportunity, enabling the client to lead the conversation rather than wait for the tools to catch up. 

In subsequent articles, we will explore the technical building blocks of this platform in greater depth, from SDK architecture and passkey authentication to account abstraction and secure device messaging.
