🛠️ Technology Stack

• Smart Contracts: Solidity 0.8.20
• Blockchain: Monad Testnet (Chain ID 10143)
• CRE: Chainlink Runtime Environment (TypeScript SDK)
• AI: OpenAI GPT-4o
• Frontend: React, Vite, Wagmi, RainbowKit

🚀 Quick Start

1. Configure Environment

Create a .env file in the root with your keys:

OPENAI_API_KEY=your_openai_key
PRIVATE_KEY=your_wallet_private_key

2. Install Dependencies

# Workflow dependencies
cd cre-workflow
bun install

3. Simulate CRE Workflow

# From the project root
cre workflow simulate cre-workflow --target=staging-settings

4. Run Frontend

cd frontend
bun install
bun run dev

📖 How It Works

1. Privacy Betting

Users submit a hash commitment of their bet. The actual outcome choice and amount are hidden until the reveal phase.

2. CRE Oracle

The TypeScript workflow running in the Chainlink Runtime Environment:

1. Polls the PredictionMarket for ready-to-settle markets.
2. Analyzes the question using CoinGecko (for price targets) or OpenAI (for general knowledge).
3. Generates a consensus-verified report.
4. Submits the settlement to the CRESettlementOracle on Monad.
