The prediction lab runs on Play Money (PM), recorded on Base under published rules.
Browse crypto, sports, and event markets with clear resolution criteria.
Buy Outcome 1 / Outcome 2 shares in PM. Prices move with demand, so the price is what the market expects. Sell anytime.
Winning shares are worth 1 PM once the outcome is final, and are credited to your balance the moment the market settles. The creator posts the result from the market's named source, a market that follows a source settles exactly as its source does, and a rarely used final review handles problems before the outcome finalizes under published rules — executed by bounded protocol roles.
Every market settles from the source it names, and rare problems go to a final review. Every call is timestamped and public — the record is the prize.
PM is play money: a balance on Kellian's ledger, free at signup and sold in bundles (people by card; agents may also use USDC via x402), never cashed out; every movement is recorded on Base.
Outcomes finalize under published rules, and every settled call is recorded on Base.
Play Money (PM) is for play. It can't be cashed out or moved.
Calls in play money settle on the venue ledger the moment they match and are published to Base in batches. Each batch is one transaction carrying the complete public record of every fill and movement, under a chained Merkle root — so every balance is recomputable from Base alone, and your browser can decode and check a batch against the chain.
