Problem Statement

mcg.fun is a decentralized prediction market for NFT floor price outcomes. Traders buy and sell ERC‑1155 YES/NO shares priced by an LMSR automated market maker, with time‑locked, on‑chain resolution and ETH redemption for winners. A real‑time indexer powers market discovery, positions, and analytics, while a modern React frontend delivers a smooth, wallet‑first experience. Optional autonomous AI agents provide continuous market analysis, automated resolution, and personalized portfolio guidance—without a bespoke backend.What you can do with mcg.fun:Speculate on whether NFT floors will reach specific targetsHedge collection exposure (downside or upside) with fungible sharesRely on transparent, on‑chain mechanics and redeemable outcomesBenefit from AI‑driven analysis and automated, trust‑minimized resolution
