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 equivalent based on current market rates, but the actual transaction amount is always in MINA. USD-pegged pricing (using an on-chain oracle) is planned for a future release.
Nothing breaks. The zkApp lives on Mina blockchain — it doesn't require our servers. Your buyers' proof files remain valid indefinitely. The SDK verification is entirely client-side, and for unlimited-device licenses (the default) verification is fully offline after the 14-day refund window closes — no network call to zkLicensing or anywhere else. The only thing that stops working is new purchases, renewals, and refunds routed through zklicensing.com's hosted backend. Users who already have a proof file are completely unaffected — the verification key is embedded in your app, and the on-chain state persists indefinitely.
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.
