For hosted ASIC owners · MRR rig owners
HashMaximizer is the back office for hosted rigs on MRR. It logs every offline minute per machine, reconciles your hosting invoice against your SLA, and puts rental income, mining income, and hosting cost on one P&L — in dollars. Built on the MRR API by a rig owner; it runs on my own fleet first.

The SLA credits were the first surprise. The second came from putting rental income and mining income on the same page in the same currency. I run a fleet of hosted rigs listed on MRR plus a few small miners at home — and I assumed renting beat mining. A real month of data:
9%
of my fleet's hours were actually rented
0.85×
what my rentals earned per hour vs my own mining
1.35×
my floors vs BTC-mining parity — healthy, and still not enough
The twist: my floor prices were fine. My rentals underperformed anyway, because my fleet doesn't mine plain BTC — it follows a daily signal to the best-paying SHA-256 coin, so the bar a rental has to beat is higher than parity. That comparison lives across three systems — the marketplace, the pool, and the hosting invoice — and until I put them on one page in one currency, I couldn't see it. Within a week my floors, my pool choices, and my host's credit balance had all changed. That's the product: not a dashboard, a set of numbers that change what you do.
2-minute import
Paste your MRR API keys — your rigs, hashrates, and watchers appear. Monitoring starts immediately.
Breakeven, from actuals
Enter what you paid for each rig (deposits included) — payback % and a projected breakeven date, computed from real rental + mining income, not a calculator.
Curtailment ≠ downtime
Grid curtailment, failures, and repairs tracked separately — curtailment never wrecks your uptime stats, and real outages never hide behind it.
Everything in dollars
Rental income, mining income, and hosting costs on one P&L, per machine, converted at real prices. Sats shown where you need them.
Price with confidence
Your MRR floor converted to $/day and checked against mining parity — so every rented hour beats plain mining. Well-priced rigs are better for you and for your renters.
Your host, audited
Downtime auto-logged and split failure vs curtailment. Upload the hosting invoice — it reconciles credits owed, kWh billed vs actual, and drafts the dispute.
Daily 6am brief
One email: fleet health, P&L, best coin to mine today, and anything that needs action.
Free under 50 TH/s · then $25/mo + $20 per PH/s
