The primitive.

full primer →

Whoever needs certainty about a game performance recording — not the creator — pays 0.01 USDC to have the WOTS+ chain replayed, and game designers get a signed verdict receipt they can keep.

Why this primitiveLoading details…

Kernel
a paid verification service where a third party — buyer, festival, insurer — pays 0.01 USDC over x402 to have someone else's WOTS+ chain replayed and gets a signed verdict receipt back
Drives the UI as
a verdict panel with pass/fail per nonce, the local browser verification beside the paid one, and a keepable receipt

match coordination
LOBBY · Pay to Verify
A high-throughput matchmaking engine where every 'Queue' request is a micro-transaction. Players pay per match-seek, ensuring skin-in-the-game and eliminating 'ghost' matchmaking. The facilitator settles pairs instantly, returning an EIP-3009 signed transaction that acts as the cryptographic handshake for game server entry. No subscription to play; pay only for the matches you actually find. Anyone can pay 0.01 USDC over x402 to verify someone else's QUIP chain and walk away with a receipt.
game fairness
TrueSeed · Pay to Verify
High-stakes game logic often suffers from 'house bias' skepticism. This service provides a verifiable, cryptographic entropy source via Ethereum Sepolia. 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. Anyone can pay 0.01 USDC over x402 to verify someone else's QUIP chain and walk away with a receipt.
