SkillPath · x402

Equip your character with high-fidelity traits by paying 0.01 USDC per node unlock. Each skill purchase is a cryptographic commitment to a specific build path, making specialized high-level builds rare and provably costly to attain. No more 'free' resets; deliberate progression creates market value for veteran accounts.

The primitive.

full primer →

Access to the character progression 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 simple logging to a pay-per-node model, character progression gains economic weight. The x402 primitive turns every skill choice into a micro-transactional event, preventing bot-spamming of maxed-out characters and ensuring 'meta' builds require real capital commitment.
