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.

full primer →

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.
