Solo mining

Know your odds. Down to the day.

HashGrid's built-in Solo Calculator pulls live network difficulty and price for Bitcoin, Bitcoin Cash, DigiByte, Litecoin, and Dogecoin — then tells you your real chance of hitting a block per day, month, and year. Auto-fill your fleet's hashrate in one tap — with automatic solo-vs-pool detection across 50+ mining pools.

Works with your rigs

Built for the hardware you actually run.

Native support for BitAxe, Avalon, and Hammer — plus Antminer detection — the miners on home benches and in garages worldwide.

FAQ

Questions, answered.

Which miners does HashGrid support?

BitAxe (Gamma, GammaTurbo, Supra, Ultra, Max, Hex & NerdQAxe), Canaan Avalon Q and Nano 3S, and Hammer miners (DC02/04/06 for Litecoin & Dogecoin). Antminer devices are auto-detected and monitored over the cgminer protocol too.

Is it private and secure?

Yes. HashGrid is 100% local by default — no cloud servers, no accounts, no tracking. Optional remote monitoring is end-to-end encrypted (X25519 + ChaCha20-Poly1305); the relay only ever forwards ciphertext it cannot read, and encryption keys never leave your paired devices.

Do I need a subscription?

No. HashGrid is free for up to 2 miners with all the core monitoring. To unlock unlimited miners and premium features you can either subscribe to Pro at $2.99/month or buy Premium once for $9.99 and own it forever — no subscription.

What is the HashGrid Bridge?

A small companion app you run on a home computer (macOS, Windows, or Umbrel). You pair with it once by entering a code and verifying its identity in the app. After that, HashGrid can securely reach your miners from anywhere — your miners are never exposed to the internet.

Which devices does the app run on?

HashGrid is a Universal app — it runs natively on iPhone, iPad, Mac (Apple Silicon), and Apple Vision Pro. It requires iOS/iPadOS 17, macOS 14, or visionOS 1.

Can I solo mine and track my odds?

Absolutely. The built-in Solo Calculator pulls live network difficulty for BTC, BCH, DGB, LTC, and DOGE, then shows your real chance of finding a block per day, month, and year — with one-tap auto-fill from your fleet and solo-vs-pool detection across 50+ pools.
