Every purchase and charge below is read from the Hippius chain.
How Hippius charges. Customers buy credits up front, at $1 each. Storing data then uses those credits up, charged hourly. That use is what this page calls billing. The Hippius team also gives some accounts free credits; usage paid with those is not customer money.
All figures are total customer spend, not Hippius's cut, which is not published. A third-party summary of the team's talk says 10% goes to the treasury and referrers get 5% of purchases.
