Building a Decentralized Prediction Market: A Full-Stack Architecture Guide

If you’re reading this, you already know that prediction markets are one of the most compelling use cases for smart contracts. They align incentives, aggregate wisdom, and run on infrastructure that promises censorship resistance and transparency. But turning that promise into a production-grade dApp requires more than just writing a Solidity contract. You need a coherent full‑stack architecture that handles market creation, liquidity, real‑time odds, and a frontend that doesn’t make users wait ten seconds for a page refresh. In this guide, I’ll walk through the complete stack—from the core smart contract layer down to the TypeScript SDK your frontend devs will love. I’ll assume you’re comfortable with Solidity, basic DeFi concepts, and the harsh reality that you can’t query on‑chain data directly for a UI. Let’s build. 1. Smart Contract Layer: The Heart of the Market Every prediction market protocol starts with the question: how do we represent a market on‑chain? The answer dictates e
