100% Tested Before Dispatch.

No DOA (Dead-On-Arrival) surprises.
Every Premium unit is configured to our exact protocol: firmware updated, dual-pool configured, hashrate tuned to spec, verified before it leaves the warehouse.

You don't need to be a tech expert—just plug it in and mine.

SEE OUR QA PROCESS

Never Miss a Block. Monitor your rig 24/7.

Keep your hashrate in your pocket. Track your live performance, aggregate multiple units (like a combined 18 TH/s Avalon Nano 3S fleet), and get instant mobile alerts for any network drops. We provide the exact setup guides to make professional-level monitoring incredibly easy for beginners. Never miss a block again.
