Our story
LYS started in 2017 in the back rooms of Huaqiangbei — the world's largest electronics market. The mining boom had just hit and overseas buyers had no reliable way to source genuine ASIC parts: fakes, mismatched specs, and disappearing sellers were the norm.
We built LYS to be the partner we wished we had: real engineers, real accountability, real follow-through. Nine years on, that's still the job.
Our mission
Keep the global mining community running — with parts you can trust, prices that make sense, and people who pick up the phone.

How fast do orders ship?
Lead time depends on the parts ordered, quantity, and stock availability — we communicate the expected dispatch window as part of your quote so you know what to plan for. Once shipped, transit time is typically 3-10 business days worldwide via DHL, FedEx or UPS. Sea freight available for larger orders.
What payment methods do you accept?
Visa, Mastercard, American Express, JCB, Discover, UnionPay, Apple Pay, Google Pay, cryptocurrencies (Bitcoin, USDT, USDC), and T/T USD bank wire transfer for professional and bulk orders. T/T is preferred above approximately $5,000.
