Supports efficient Bitcoin mining with custom firmware and Perpetual Tune
Longevity
Built to maximize miner ROI and extend hardware life in challenging environments.
Bitcoin Mining Fleet Enhancement
Built to support unexpected environmental challenges, the UMC product line is designed to maximize the performance and uptime of large-scale Bitcoin mining operations. It offers both hardware solutions and standalone firmware-only options. Supported models include air-cooled Antminer S19x to S21x variants*, offering enterprise-grade customization and system control.
- Perpetual Tune enables fully automated, self-optimizing performance—ideal for operators who require hands-off, profitable Bitcoin mining at scale
- Rich API documentation provides advanced teams with full access to mining parameters, enabling precise control over Bitcoin mining systems and fleet-level customization
Whether you prioritize automation or fine-tuned performance, UMC is the trusted custom firmware solution built for efficiency and growth.
UMC OS, the standalone firmware option, supports remote installation across large mining fleets, and with RigRunner—our user-friendly deployment tool—you can scan, install, and manage firmware updates at scale without command-line expertise.

Mining Rigs
Our deep experience in mining rigs design and optimization enables us to build custom Bitcoin miners. Our mining rigs are built to the specifications of our customers with specific emphasis on cost, performance/hashrate, and thermal solution including liquid immersion and hydro. Our designs go through rigorous testing and qualification to ensure maximum uptime and profitability in the field.
We also offer a range of mining rigs for Altcoins; more details on new systems for PoW algorithms coming!
Blockchain Chips
We have a strong record in high-performance chip design from the most respectable chip companies in North America. Our experience includes GPU designs for gaming and AI, video technologies, firmware, and high-speed mixed-signal IPs for FinFET processes. We harness this experience to design custom chips for the blockchain economy with an eye to performance, efficiency, and mining profitability.
Our chips are manufactured by TSMC. We are very fortunate and appreciative of our close relationships with TSMC, an important pillar of our competitive advantage.
