NEURAFLOW · x402
A persistent state layer for autonomous game entities. Every time an NPC 'remembers' a player interaction, retrieves a past dialogue, or updates its emotional bias, the game engine triggers an x402-signed call. Instead of flat server costs, NPCs act as autonomous accounts that pay 0.01 USDC to write/retrieve their own history on Hedera. Payment is the literal cost of cognition and permanence.
The primitive.
Access to the non-player character data 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 primitiveGame developers currently struggle with the high cost of persistent LLM memory. By moving memory to a pay-per-read/write model settled on Hedera, NPCs become portable assets across different game worlds, carrying their history via self-sovereign micropayments.
