Predict.fun Trading Interface
Community Trading Interface for Predict.fun Prediction Markets
Problem
Predict.fun hosts prediction markets on BNB Chain but lacks a community-built trading interface that exposes the full orderbook, limit/market order flow, and position management in a single app. Traders need a responsive front-end covering both Testnet (for experimentation) and Mainnet (for live trading) with a standard wallet-connection stack.
Approach
- Next.js 14 App Router for colocated routing, server components, and streaming-friendly data fetching.
- wagmi + RainbowKit for production-grade wallet connection with minimal custom code.
- Dual-network support (BNB Testnet and Mainnet) selectable via wagmi chain config.
- TanStack Query for orderbook and position state with automatic refetching.
- shadcn/ui for composable, accessible trading UI primitives.
Implementation
Trading Features
Market browsing with search, orderbook display with real-time updates, limit and market order creation, and position management including open-order cancellation and order history.
Wallet Integration
RainbowKit handles wallet discovery and connection, wagmi provides typed contract interactions and chain switching, and TanStack Query coordinates on-chain state with the UI. Both BNB Testnet and Mainnet are supported via chain configuration.
UI/UX
Trading interface built on shadcn/ui primitives under the Next.js 14 App Router, with a responsive layout that covers desktop and mobile trading flows.
Outcome
- End-to-end trading interface for Predict.fun markets covering browse, orderbook, order placement, cancellation, and history.
- Cross-network support for BNB Testnet and Mainnet from a single deployment.
- Standard wagmi/RainbowKit wallet stack compatible with mainstream BNB-Chain wallets.
