Private Prediction Market

A Solana-based prediction market where users can make private binary predictions (YES/NO) using a commit-reveal scheme. Markets resolve automatically using Pyth Network's SOL/USD oracle.

How It Works

The Flow

1. Admin creates a market with a question, resolution time, and SOL price threshold
2. Users stake wSOL and commit their hidden prediction (YES or NO)
3. Market resolves automatically when resolution time passes, using Pyth oracle
4. Users reveal their prediction before the deadline
5. Winners get their stake back (1x refund), losers lose their stake

Why Private?

Your prediction is stored as a hash on-chain until you reveal it. No one can see what you bet until after the market resolves. This prevents front-running and manipulation.

Architecture

Program (Rust/Anchor)

• Program ID (devnet): 6CY8YgqAoXq66baW5B41Yw72D7unQjFN3wuMkZr2bCRM
• Key accounts:
  • Config: Global settings (admin, token mint, fee recipient)
  • Market: Market data (question, resolution time, price threshold, vault)
  • UserPosition: Per-user commitment and reveal state

Frontend (Next.js)

• Wallet integration via Solana Wallet Adapter
• Server-side Pyth price fetching (API route)
• Full admin panel for market management

Quick Start

Prerequisites

• Rust + Anchor CLI
• Node.js + npm/yarn
• Solana CLI (devnet configured)
• Devnet SOL: solana airdrop 2

Deploy Program

anchor build
anchor deploy

Run Frontend

cd frontend
npm install
npm run dev

First Time Setup

1. Connect wallet → Initialize tab → Initialize config
2. Create Market → Set question, resolution time, price threshold
3. Stake & Commit → Enter market ID, amount, choose YES/NO → Save the salt!
4. Wait for resolution time → Admin → Resolve Market
5. Reveal & Claim → Enter market ID, outcome, salt → Get refund if correct

Key Features

• Commit-reveal: Predictions hidden until reveal
• Pyth oracle: Automatic resolution based on SOL/USD price
• Simple payouts: 1x refund for correct predictions
• Admin tools: Create markets, resolve, forfeit unrevealed stakes

Program Instructions

• initialize: Set up global config (admin only)
• create_market: Create new prediction market
• stake_and_commit: Stake tokens and commit hidden prediction
• reveal_and_claim: Reveal prediction and claim refund if correct
• resolve_market: Resolve market using Pyth oracle (admin only)
• forfeit_unrevealed: Transfer unrevealed stakes to protocol (admin only)

Deploy to Vercel

1. Push repo to GitHub
2. Import in Vercel → Set root directory to frontend/
3. Add environment variables
4. Deploy

Important Notes

• Devnet only: This is an MVP, not production-ready
• Re-initialize after redeploy: New program ID means fresh start
• Save your salt: You need it to reveal and claim
• Reveal deadline: 2 weeks after market resolution
