PAYLOAD · x402

$0.01 — pay-per-input. A hyper-casual multiplayer engine where every move, spell cast, or strategic toggle is a micropayment. Eliminate 'free-to-play' friction with 'pay-to-play' precision: players sign an HTS transfer authorization to stream USDC per game tick. Facilitators settle batch moves on Hedera, turning the global leaderboard into a literal real-time revenue stream where winning matches redistributes the pool.

The primitive.

full primer →

Access to the multiplayer mechanics 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 primitiveReplacing 'gasless' (overhead) with 'micro-paid' (revenue). By pricing inputs at $0.01, the game shifts from a subsidized expense to a self-sustaining economy where the cost of compute and state-sync is covered by the player in real-time.
