Enigma Meter · x402
A cryptographically-linked puzzle engine where solving or accessing the next stage requires a 0.01 USDC micro-settlement. Creators earn per-solve royalties, and players pay-per-hint or pay-per-level using X402-gated interactions. No subscriptions, just friction-less progression via signed HTS transfer intents.
The primitive.
Access to the interactive puzzle 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 primitiveThe 'NFT ownership' model is static; X402 turns the puzzle into a metered service. By making each move or hint a 1-cent transaction, it creates a high-velocity 'micro-economy' for game designers where the financial settlement (Base tx) is the evidence of the solve.
