Description

The Vision

Prediction markets are the source of truth, but they are hard to navigate. Users have to browse hundreds of markets to find alpha. https://prophet-ai-eta.vercel.app changes this.

Instead of searching, you ask.

"Will Bitcoin hit $100k?"
"Is the Mantle Airdrop confirmed?"

The AI Oracle:

Understands your intent.
Scans live Polymarket data for the exact event.
Analyses the odds and news.
Challenges you to place a bet on-chain if you disagree with the market.

Key Features

AI Oracle Chat: A full-screen, immersive chat interface powered by GPT-4o. Just talk to it: "Bet $50 on Yes".
Markets Explorer: Real-time dashboard of trending global events, fetching "Trending" and "High Volume" markets.
Seamless On-Chain Actions: Deployed smart contracts on Mantle Sepolia for betting logic with frictionless wallet connection.

Technical Architecture

Frontend: Next.js 14 (App Router), Tailwind CSS, Framer Motion.
Smart Contracts: Written in Solidity, deployed on Mantle Sepolia.
AI Engine: OpenAI GPT-4o via Vercel AI SDK with custom function calling for odds analysis.
Data: Polymarket Gamma API.

Progress During Hackathon

I successfully built and deployed the full end-to-end flow: Smart Contracts: Developed and deployed ProphetMarket.sol on the Mantle Sepolia network. AI Agent: Integrated GPT-4o with custom tool calling to fetch live market data and structure bet parameters. Frontend: Built a responsive, dark-mode "Chat with Oracle" interface using Next.js and Tailwind. Integration: Connected the AI intent engine with on-chain transaction signing via Wagmi/Viem.
