Kromos · x402
A stateless character-smith where every aesthetic choice—from skin shader to gear mesh—is a 0.01 USDC unlock triggered via signature. Instead of buying a whole NFT, players 'stream' their identity by paying for the specific frame-data and rig-assets they use per session. Developers earn real-time royalties every time a player equips their designed layer, turning character customization into a high-frequency micro-transaction loop.
The primitive.
Access to the character customization 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 primitiveBypasses the 'lumpy' cost of minting full NFTs by decoupling the asset from the token. Using x402 allows for granular 'pay-per-equip' or 'pay-per-render' models, making high-quality community-made assets accessible for pennies while ensuring creators are paid instantly for every usage instance.
