Judge Me If You Can 😏 was built using a modern, full-stack web3 approach, combining both on-chain and off-chain components for efficiency and real-time performance. At its core, the project leverages Next.js for the frontend framework, paired with Tailwind CSS to create a sleek, responsive, and visually appealing interface. The Electron.js wrapper powers the macOS notch app, enabling native-like desktop notifications and interactions that keep users engaged without disrupting their workflow.

For real-time market data, we integrated Pyth Network price feeds via their API, ensuring accurate and up-to-date information across multiple asset classes including stocks, cryptocurrencies, fiat currencies, and metals. User interactions, wallet balances, and bet histories are stored securely in Supabase, providing a scalable and easy-to-query backend solution. To handle web3 wallet connections and transactions seamlessly, RainbowKit was incorporated, making it simple for users to connect their wallets and place predictions without friction.

The development process followed a first-principles approach. We took a complex problem—combining prediction markets, real-time notifications, and on-chain interactions—and broke it down into its essential components. This allowed us to create a proof-of-concept that includes only the critical parts: on-chain logic for bets and payouts, off-chain handling for notifications and state management, and a streamlined UI for fast decision-making.

We also explored some creative engineering hacks to bridge off-chain and on-chain logic efficiently. For example, the Electron notch app subscribes to live updates and triggers notification prompts simultaneously for all users, maintaining fairness without putting unnecessary load on the blockchain.
