LootCrack · x402

A high-frequency loot-cycling engine where players pay 0.01 USDC to 'crack' regional drop-tables. Instead of subscription-based RNG, every item acquisition is a discrete micropayment transaction. Use x402 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 Hedera.

The primitive.

full primer →

Access to the item distribution engine is metered with x402: 0.01 HBAR or 0.01 HTS USDC per call, paid from the embedded wallet, so game designers — or the agents working for them — pay per query and get a HashScan receipt every time.

Why this primitiveBy moving loot interaction from an 'all-you-can-eat' model to a per-drop micropayment, the developer captures value on every single player engagement. x402 eliminates the friction of gas-fees-per-claim by bundling the logic into the transaction auth, making 'pay-to-open' a seamless game mechanic.
