CIPHERPAY · x402
A modular puzzle engine where every 'Check Solution' action is a $0.01 USDC micro-transaction. Players pay per attempt to validate complex logic gates or cryptographic riddles against a Hedera testnet facilitator. Game designers receive instant settlement for their content loops, turning difficulty curves into direct revenue streams. No subscriptions—just pay to solve.
The primitive.
Access to the interactive puzzles 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 the 'Attempt' button into a paid HTS transfer call, the app eliminates bot-spamming of brute-force solutions and creates a high-stakes competitive environment where logic efficiency has a literal monetary value.
