A wearable Bitcoin miner. Real SHA-256 hashing on your wrist. Every hash is a shot at the 3.125 BTC block reward.
Every SOLOMINER runs actual SHA-256 computations, submitting shares to the Bitcoin network.
No pool fees. No reward splitting. Public-pool.io relays your work to Bitcoin. If you find a block, 100% of the 3.125 BTC goes to your wallet.
Actual SHA-256 mining on your wrist. Watch your hashes tick up in real-time on the AMOLED display.
Swipe between Mining and Clock screens. Tap to wake. Smart auto-dimming saves battery.
Built on NerdMiner V2 - we're standing on the shoulders of a great open source project. Full source code available on GitHub when devices ship.
Scan the QR code on device to open setup. Enter WiFi and your Bitcoin wallet address.
SOLOMINER connects to public-pool.io and starts mining.
If you solve a block, 3.125 BTC goes directly to your wallet.

Every hash is a chance. At current difficulty, the odds are astronomical - but someone has to win.
SOLOMINER is a small project built around a simple idea: individual participation in Bitcoin mining.
Mining is usually abstracted away, handled by large operators, distant facilities, and layers of infrastructure most people never touch. But at the protocol level, mining is just contributing work to the network. SOLOMINER makes that contribution visible and personal.
The watch isn't designed for profitability or scale. It exists to demonstrate that mining is not location-dependent and does not require permission. It can happen anywhere, on a device you control.
SOLOMINER is fully open source and built on top of the NerdMiner V2 project. Development is public, improvements are driven by community input, and software updates are released freely.
This is not a replacement for industrial mining. It's a reminder of what mining actually is.

Statistically, it's extremely unlikely. At ~250 KH/s, the odds are astronomical. But solo miners have won before.
Early testing showed around 4 hours of continuous mining before any optimization. We've since added smart power management: the screen dims after 30 seconds and turns off after 2 minutes. This should extend battery life significantly. We'll publish final numbers before shipping. And of course, it mines indefinitely while charging via USB-C.
Very little. The watch sends small data packets to the mining endpoint - roughly 10-20 MB per day. Easy to run off your phone's hotspot.
Yes. By default it connects to public-pool.io for solo mining, but you can configure any compatible pool through the device settings. The firmware is open source, so advanced users can customize it however they like.
First batch ships late February 2026. Pre-orders are first-come, first-served.
