ForgeStream · x402

A programmable forge for the agent-gaming era. Instead of static minting, players deploy interactive item logic gated by x402. Want to equip a legendary blade? Sign a 0.01 USDC HTS transfer request to 'unsheathe' the metadata. Creators get paid every time their item is activated, equipped, or triggered in-game, turning UGC from a one-time sale into a streaming royalty model. Processing happens on Hedera testnet, returning a tx hash as the 'proof of utility'.

The primitive.

full primer →

Access to the user-generated content 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 primitiveShifts UGC from 'ownership' to 'usage.' By micro-charging for the activation of item effects, creators earn based on the actual popularity and utility of their designs within the game loop.

quest tracking
Milestone · x402
Turn every quest step into a verifiable micro-transaction. Players pay $0.01 USDC to sign 'Proof-of-Completion' for individual milestones, instantly updating a global leaderboard. Developers monetize gameplay depth through high-frequency, low-friction state updates rather than binary loot boxes. Fractionalize game progress: pay-per-checkpoint, pay-per-achievement, and pay-to-audit.
item distribution
LootCrack · x402
A high-frequency loot-cycling engine where players pay 0.01 USDC to 'crack' regional drop-tables. Instead of subscription-based RNG, every item acquisition is a discrete micropayment transaction. Use x402 to meter high-value item reveals, ensuring that rare 'Legendary' pulls generate immediate protocol revenue while providing players with a cryptographic receipt of authenticity on Hedera.
