Quest Node · x402
A decentralized vault of high-fidelity quest logic where game engines and dungeon masters pay per branch. Instead of opaque game files, Quest Node serves HTS transfer signed decision trees. A 0.01 USDC micro-transaction unlocks the next narrative state, validates player inventory prerequisites, and manages state transitions on-chain. Developers can subscribe their NPCs to this logic or players can pay to 'unlock' hidden lore paths in real-time.
The primitive.
Access to the interactive quest design 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 primitiveBy turning quest logic into a metered API, narrative designers monetize the 'intelligence' of their world-building. x402 allows for granular story-gating where the cost of the adventure scales with the complexity of the player's choices, creating a direct value link between writing and gameplay.
