OracleBet: Decentralized Prediction Markets on Mantle Network

OracleBet is a decentralized prediction market platform built on Mantle Network that enables users to create and trade on prediction markets for crypto prices, Real-World Asset (RWA) yields, and ecosystem events with ultra-low fees and fast transactions.

Problem Solved:

Traditional prediction markets are expensive and slow, limiting micro-bets and high-frequency trading. OracleBet leverages Mantle's efficient L2 infrastructure to enable cost-effective, scalable prediction markets.

Key Features:

Ultra-Low Fees: Only 0.1% trading fees, enabled by Mantle's low gas costs

Multiple Market Types: Crypto price predictions, RWA yield forecasts, and Mantle ecosystem events

Decentralized Oracles: Integration with Chainlink price feeds and UMA optimistic oracles for reliable market resolution

Constant-Product AMM: Automated market maker for price discovery and liquidity

Portfolio Management: Track positions, winnings, and market performance

Modern UI: React + TypeScript frontend with dark mode, responsive design, and smooth animations

Technical Implementation:

Smart Contracts: Solidity contracts deployed on Mantle Sepolia Testnet using Hardhat

Frontend: React 18 with TypeScript, Vite, Tailwind CSS, and shadcn-ui components

Web3 Integration: Wagmi + RainbowKit for seamless wallet connections

Architecture: Factory pattern for market creation, ERC20 share tokens for Yes/No positions

Why Mantle:

Mantle's low fees and fast finality make it ideal for prediction markets requiring frequent trades and oracle queries. The platform supports micro-bets and high-volume trading that would be cost-prohibitive on other networks.

Use Cases:

Traders betting on crypto price movements

DeFi users predicting RWA yield changes

Community members forecasting ecosystem events

Liquidity providers earning fees from market pools

OracleBet demonstrates how Mantle's infrastructure can unlock new DeFi use cases through cost-effective, scalable prediction markets
