SOURCECODE · x402

A headless protocol for game engines where every mod download, asset swap, or plugin load triggers a $0.01 micro-royalty to the original creator. Instead of static minting, x402 enables 'Live Provenance'—where the game client verifies the signature and pays the contributor's Magic Link email sign-in in real-time to unlock the asset data at runtime.

The primitive.

full primer →

Access to the modding community tools 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 modding from a 'donation-optional' model to a high-velocity 'usage-settled' economy. By making the payment the access primitive, creators are incentivized to build interoperable assets that earn every time a player enters a new zone or loads a skin.

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.
community trust
Proof of Honor · x402
$0.01 — pay-per-vouch. A high-integrity matchmaking layer where players pay to submit peer reviews and developers pay to query the 'Karma' API. By attaching a micro-cost to reputation, you eliminate sybil attacks and bot-spam, ensuring that only skin-in-the-game sentiment defines a player's standing. No free reports, no fake fluff.
