Waypoint · x402
A location-based 'Proof of Presence' engine where every clue reveal and waypoint verification costs a 0.01 USDC micropayment. Players pay to unlock the next leg of the hunt, while creators earn instant, metered royalties for game design. Successful completion triggers a Base transaction hash that acts as an immutable voucher for physical rewards or digital loot.
The primitive.
Access to the interactive exploration 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 a free model to a pay-per-clue x402 primitive, the scavenger hunt becomes a self-sustaining economy. It prevents botting/spamming of game logic and allows creators to monetize 'micro-adventures' without high-friction subscription fees.
