Enigma Grid · x402

A programmable vault for procedural game logic. Designers publish puzzle 'blueprints' (state machines, move-sets, solution trees) that cost $0.01 per import or validation. Players pay to verify a solution against the immutable cache, while developers pay to remix existing archetypes into new levels. Payment is the gravity that keeps the puzzle economy balanced—no free solves, no stolen logic.

The primitive.

full primer →

Access to the game mechanic storage 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 moving puzzle validation off-client and onto a pay-per-call infrastructure, you turn game design into a series of micro-transactions. This prevents 'spoiler' data mining and creates a direct revenue stream for mechanics designers.
