Milestone · x402

Turn every quest step into a verifiable micro-transaction. Players pay $0.01 USDC to sign 'Proof-of-Completion' for individual milestones, instantly updating a global leaderboard. Developers monetize gameplay depth through high-frequency, low-friction state updates rather than binary loot boxes. Fractionalize game progress: pay-per-checkpoint, pay-per-achievement, and pay-to-audit.

The primitive.

full primer →

Access to the quest tracking 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 quest tracking from a free database entry to an x402-metered event, 'Quest Log' transforms game progression into a real-time revenue stream. It eliminates sybil-farming of rewards by requiring a $0.01 economic stake for every milestone recorded, ensuring only committed players populate the chain.
