I Built a Prediction Market on Solana — Here's How It Works

Description

Been working on InstinctFi for a while, it's a prediction market platform where you vote on real-world outcomes using SOL. If your side wins, you split the losing pool. Pretty simple concept but getting the smart contract right took some work. This video walks through the whole thing how you create polls, how voting works, how settlement happens, and the 1% fee model.
