LootCrack · Paid Certificate

Instead of subscription-based RNG, every item acquisition is a discrete micropayment transaction. Use QUIP to meter high-value item reveals, ensuring that rare 'Legendary' pulls generate immediate protocol revenue while providing players with a cryptographic receipt of authenticity on Base. Paying 0.01 USDC over x402 returns a signed provenance certificate for the work.
