Multi-Chain Prediction Market

Real-time on-chain prediction & parlay platform across five EVM chains.

Overview

A decentralized prediction and parlay platform where users place and settle bets fully on-chain, deployed across several EVM networks (Sanko/APE, Base, Ethereum, Sonic) from a shared codebase.

Live odds and price data stream over websockets, while Solidity contracts handle settlement, a substantial DeFi system with a per-chain front-end build architecture.
