The problem
Prediction markets only work if people can trust the payout. That trust has to live in the contract, not in whoever runs the site, and the contract has to handle deposits, resolution and settlement without an escape hatch for the operator.
What we built
We contributed to the smart contract design behind the platform: markets that take USDC deposits on either side of a yes or no question, hold the funds in escrow until the outcome resolves, and settle positions on chain so no operator sits between a winning position and its payout.
Results
- Contract design for market creation, escrow, resolution and settlement
- USDC deposits held on both sides of a market until it resolves
- On-chain settlement, so payouts do not depend on the operator
