Merchantier

An innovative prediction market platform built with Chainlink CRE (Confidential Reporting Engine) that leverages AI to enable decentralized market settlement. This project combines smart contracts, event-driven workflows, and AI-powered oracles to create autonomous prediction markets.

This prediction market platform is built to allow users to:

• Create prediction markets for any binary question (Yes/No)
• Make predictions by staking ETH on their beliefs
• Earn rewards if their prediction is correct
• Automate settlement using AI and Chainlink CRE for trustless market resolution
  The platform uses Chainlink's CRE infrastructure to trigger AI analysis when markets request settlement, ensuring objective and decentralized decision-making without relying on centralized authorities.
  🏗️ Architecture

Smart Contracts (/contracts/src)

PredictionMarket.sol

• Core contract managing market lifecycle
• Handles market creation, predictions, and settlement
• Stores market data and user predictions
• Implements secure fund management and payout distribution
  Key Features:
• Binary prediction markets (Yes/No outcomes)
• Pool-based reward distribution
• Confidence-weighted settlement
• Secure fund transfers with validation
  Workflow Engine (/my-workflow)

The workflow automates market settlement through two main triggers:
HTTP Trigger (Market Creation)

• Receives market creation requests

• Triggers AI analysis via Google's Gemini LLM

• Processes settlement recommendations
  Log Trigger (Event-Driven Settlement)

• Monitors SettlementRequested events on-chain

• Automatically triggers AI analysis when markets request settlement

• Ensures timely and reliable market resolution
  API Integration

• Google Gemini LLM: Analyzes market questions and generates settlement recommendations

• Chainlink CRE SDK: Manages decentralized workflow execution

• EVM Compatible: Works with Ethereum Sepolia testnet
