Prediction Market Platform

A decentralized prediction market platform built with Next.js, Supabase, and RainbowKit for MetaMask wallet integration.

Note on Deployment

Head to http://10.40.197.61:3001/ for a working blockchain implementation, since Vercel cannot interface with the server. This link will work when our server is up and running.

Features

• Admin Dashboard: Create prediction markets with custom questions and descriptions
• Shareable Links: Generate unique links for each market to share with participants
• Wallet Integration: Connect with MetaMask using RainbowKit
• Confidence Voting: Vote with confidence levels from 0 to 1 (0% to 100%)
• Real-time Statistics: View live voting results and market statistics
• Auto-resolution: Markets automatically resolve based on weighted vote thresholds
