LEVELUP · x402

An open inventory for custom game logic where creators earn $0.01 USDC every time a player loads their level. Bypass traditional storefront tax; players use the embedded wallet-signed HTS transfer auth to 'rent' a level session for a fraction of a cent. High-score data and level state are validated only upon payment, turning UGC into a micro-revenue stream for indie designers.

The primitive.

full primer →

Access to the user content 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 shifting from 'gas-free' to 'micro-paid,' the friction moves from the network to the value exchange. Creators are incentivized to build quality content because each play-session is a direct, instant settlement on Hedera.
