Hey Product Hunt 👋 I'm Marcos, solo founder and builder of Bopster Fun. What is Bopster? Bopster is a non-custodial prediction market on Base where communities create their own markets instead of waiting for a platform to list them. No email signup, no custody — just connect your wallet and go. 🎯 Four ways to earn: 🏆 Back YES or NO with USDC — win the pool if you're right 💰 Create a market — earn 1% of the pool automatically when people participate ⚡ Finalize settled markets on-chain — earn resolver rewards 🔮 Submit correct oracle answers — earn bond rewards 🔗 How it works under the hood Solidity smart contracts on Base. Reality.eth for decentralized oracle resolution (anyone can answer, wrong answers get challenged, each challenge costs 2x the bond). Kleros for arbitration when disputes escalate. USDC for all market activity. ETH for gas and oracle bonds. Everything on-chain, everything verifiable. Bopster never touches user funds. 📂 Open-source. No token, no ICO, no airdrop. 🧪 Who I'm looking for This is early-stage. I'm a backend dev who built this solo. I'm looking for honest feedback from prediction market users (Polymarket, Kalshi), creators who debate with their audience, and Base builders. Create a market, take a position, try the resolution flow — then tell me what broke, what confused you, and what you wish existed. ⚡ Known limitations Bopster is experimental software. Use at your own risk. Not available in the US or Spain for legal reasons. Market resolution depends on community participation — there's no central operator resolving markets. 💬 Ask me anything about the tech stack, the oracle architecture, the template system, why I chose Base, why there's no token, or what it's like building a two-sided marketplace as a solo dev. I'll be here all day replying to every comment. Roast it — I want the feedback.
