SkinStream · x402

A real-time asset protocol where every player interaction with a cosmetic—equipping, trading, or viewing in-lobby—triggers a $0.01 micro-royalty to the original artist. No bulky upfront minting fees; pay-per-frame utility for ultra-rare skins. Non-custodial, high-velocity vanity.

The primitive.

full primer →

Access to the cosmetic item creation 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 primitiveMoving from static 'NFT minting' to 'metered usage' solves the liquidity issue for digital fashion. Instead of high barriers to entry, players 'stream' the skin's presence in-game, creating a continuous revenue loop for creators and a low-friction trial for players.
