Settled Developer Documentation

Settled is a prediction market platform for crypto funding rates on Solana. Markets auto-create before each funding settlement and auto-resolve using exchange API data.

What you can build

• Trading bots that scan for mispriced markets and execute trades via REST API
• Data pipelines that consume real-time price updates via WebSocket
• Analytics dashboards using historical settlement and resolution data
• Arbitrage strategies across 19 series spanning Binance, Bybit, KuCoin, Gate, and Hyperliquid
