TrueSeed · x402
High-stakes game logic often suffers from 'house bias' skepticism. This service provides a verifiable, cryptographic entropy source via Hedera testnet. Players pay 0.01 USDC to trigger a 'Trustless Roll' signed by their Magic Link email sign-in. The payment acts as the commitment hash, ensuring the developer cannot manipulate the outcome after seeing the seed. Perfect for loot boxes, critical hits, or procedural map generation where fairness is a billable feature, not a promise.
The primitive.
Access to the game fairness 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 RNG from a hidden server function to a paid, user-initiated transaction, transparency becomes the product. The micropayment provides the economic audit trail for every 'luck' event in the game.
