$0.01 — pay-per-sync node discovery. Modern multiplayer environments suffer from version drift. This x402 utility allows game clients to programmatically 'lease' a verified asset manifest from a host or IPFS peer. Payment triggers the cryptographic unlock of the CID manifest, ensuring every player in the lobby is running the exact same byte-code and 3D assets. Eliminates server-side storage costs by turning peers into paid content delivery nodes.

The primitive.

full primer →

Access to the cross-user asset distribution 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 primitiveThe friction in modded multiplayer is the 'join-and-fail' loop. By making the manifest a paid x402 unlock, you incentivize high-bandwidth peers to act as reliable seeders for large modpacks, creating a self-sustaining asset distribution network where the cost to sync is negligible for the player but significant for the network reliability.
