#predictAI is the platform that combines AI with prediction marketplace to make it super scalble with decentralized event (bet) creation.

How It Works:

Users log in via Dynamic's simple authentication. They choose a topic or use AI to generate interesting bets. Participants place bets using testnet funds (easily obtained through our integrated faucet). For crypto-related bets, Pyth Network provides accurate, real-time price data. When a bet concludes, our AI (powered by Phala Network) analyzes the latest information to determine the winner.

How We Built #predictAI: The Nitty-Gritty Details

Our goal with #predictAI was to create a seamless, AI-powered prediction marketplace. Here's a deep dive into our tech stack and build process:

Core Technologies:

1. Frontend: Next.js with TypeScript

   • Chose for its server-side rendering capabilities and TypeScript support
   • Used Tailwind CSS for responsive design

2. Smart Contracts: Solidity

   • Deployed on Morph's Holesky testnet
   • Handles bet creation, participation, and settlement logic

3. Backend AI: Phala Network's Agent Contract plus OpenAI for backup

   • Implemented in TypeScript
   • Runs in Phala's TEE (Trusted Execution Environment) for secure, tamper-proof execution

4. Authentication: Dynamic SDK

   • Integrated for email,wallet and Telegram logins
   • Leveraged Dynamic's Telegram Auto Wallets for seamless crypto onboarding

5. Oracle Integration: Pyth Network

   • Used for real-time cryptocurrency price data
   • Implemented Pyth's pull oracle pattern for on-chain data updates

Integration and Challenges:

1. AI-Agent Contract by Phala : The gas kept running out,had to use multiple apis

2. UX - Challenge: Simplifying the testnet fund acquisition process

   • Hacky Solution: Created a "Request Funds" button that interacts with a custom faucet contract. This contract checks for cooldowns and distributes a fixed amount of testnet tokens, all in one transaction.

Partner Integrations :

1. Phala Network:

   • Used for both bet generation and outcome determination
   • Leveraged Phala's secure environment to ensure fairness in AI decision-making

2. Dynamic:

   • Integrated Telegram login for one-click crypto account creation
   • Used Dynamic's EventEmitter to handle wallet connection states across the app

3. Pyth Network:

   • Implemented a custom caching layer to optimize Pyth data fetches
   • Used Pyth's confidence intervals to adjust bet parameters dynamically

4. Morph:

   • Deployed our main contract on Morph's Holesky testnet
   • Utilized Morph's faster block times for a more responsive betting experience

The most challenging (and rewarding) part was orchestrating these diverse technologies into a cohesive, user-friendly platform. Our "Request Funds" feature, while simple on the surface, required careful integration with Dynamic's wallet creation process and our custom faucet contract.
