Proof of Rank · x402

Convert game stats into competitive assets. Every leaderboard update, challenge submission, and rank-climb requires a 0.01 USDC micro-stake via HTS transfer. This transforms "vanilla" tracking into a high-stakes, pay-to-play arena where players pay to prove their worth, and top performers earn automated distributions from the pool.

The primitive.

full primer →

Access to the competitive 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 replacing gasless/sponsored models with x402, value is captured at the moment of competitive proof. It removes the 'free-rider' problem of leaderboards and ensures only committed players populate the top tiers, while creating a self-sustaining revenue stream for the game facilitator.
