ForgePath · x402

Every XP gain, skin evolution, or weapon forge is a paid state transition. Use x402 to meter the 'Life Path' of your assets—0.01 USDC per mutation. Players don't just win items; they buy the right to evolve them via micro-transactions that settle on-chain instantly, making every visual upgrade a proof-of-investment. Fees go directly to the game balance for real-time asset upkeep.

The primitive.

full primer →

Access to the asset evolution 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 pricing the evolution event rather than the final asset, you create a high-velocity micro-economy. x402 replaces the 'grind' with a literal 'pay-to-grow' mechanic that is affordable but creates a continuous revenue stream for developers and a verifiable cost-basis for players.
