Arcade Gate · x402

Move beyond all-or-nothing ownership. Gate high-stakes game states, secret levels, or powerful items behind 0.01 USDC x402 signatures. Players pay per respawn, per floor, or per interaction, creating a frictionless arcade-style economy where the facilitator settles state changes directly on Hedera. No inventory friction—just signed intent and instant play.

The primitive.

full primer →

Access to the access control 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 primitiveTraditional token-gating is binary and static; x402 turns game access into a flow. By metering specific interactions (e.g., 'Pay 0.01 USDC to enter the Boss Room'), developers capture value from every engagement while players avoid high upfront costs. This is the 'Insert Coin' primitive for the on-chain era.
