FAQ

Common questions

The fee split is compiled into the zkApp circuit itself — not enforced by our servers. When you deploy your app, the circuit's logic (including the 2% split to the platform address) is compiled into the verification key. Changing the split would produce a different verification key, which your buyers' apps would reject. It's mathematically enforced.
License prices are denominated in MINA on-chain. The buyer page shows an estimated USD and EUR equivalent based on current market rates, but the actual transaction amount is always in MINA.
Existing users keep working. The SDK's verify runs client-side against Mina directly — it reads on-chain state from a public Mina node, not from our servers — so buyers already holding a proof file are unaffected for the duration of the outage. For unlimited-device licenses (the default), verify is fully offline once the 14-day refund window has closed. What pauses during an outage: new purchases, renewals, refunds, and device bind/unbind flows that route through zklicensing.com's hosted backend. Those resume when the platform is back up.
Every license carries a 14-day refund window, enforced in-circuit — buyers can self-refund within that window by submitting a refund transaction. The MINA returns to the buyer on-chain and the proof becomes invalid. The window is not vendor-configurable; it's a fixed property of the licensing circuit, the same for every listing.
