This project is inspired by the leading prediction market platforms:
| Platform | Chain | Model | Status |
|---|---|---|---|
| Polymarket | Polygon | CLOB + Gnosis CTF | 🟢 #1 by volume, $1B+ monthly |
| Kalshi | Off-chain | CFTC-regulated exchange | 🟢 US-regulated, real-money |
| Azuro | Polygon, Gnosis | Liquidity pool + AMM | 🟢 DeFi-native, permissionless |
| Overtime Markets | Optimism, Arbitrum | Thales AMM | 🟢 Sports-focused |
| Augur | Ethereum | Fully decentralized | 🔴 Inactive (pioneer, launched 2018) |
| Gnosis / Omen | Gnosis Chain | CTF + AMM | 🟡 Low activity |
| Hedgehog | Solana | Parimutuel pools | 🟡 Solana ecosystem |
| PlotX | Polygon | AMM-based | 🔴 Discontinued |
| This Project | Polygon | CLOB + Smart Contract Escrow | 🟢 Open Source |
- Polymarket is closed-source and US-restricted — you can't customize or deploy it
- Kalshi requires CFTC license — not accessible for most teams
- Augur/Omen are fully on-chain — slow and expensive for real users
- This project gives you a production-ready, customizable platform you own and control
The complete production-ready platform includes:
- Smart Contract — Audited BetMarketV1 with UUPS upgrade support
- Java Backend — Complete REST API with order matching, settlement, admin
- Admin Panel — Vue-based dashboard for event/contract/user management
- Mobile App — Android APK ready for distribution
- Deployment Scripts — Hardhat deploy/upgrade, Docker configs
