PROP-FETCH · x402
A cross-engine protocol for game asset instantiation. Developers pay 0.01 USDC to fetch a cryptographically verified 'Prop Bundle' (3D mesh, collision data, and physics scripts) from the Base ledger into their runtime. Payment guarantees the asset’s permanent availability and provenance, preventing broken dependencies in persistent worlds. Creators receive instant micropayment royalties every time their prop is spawned in a new game instance.
The primitive.
Access to the asset permanence 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 primitiveTraditional asset stores use heavy upfront licenses. By moving to a pay-per-instantiation model, indie devs reduce overhead while creators generate high-volume, passive revenue from 'viral' assets used across the metaverse.
