About DeepBook V3

DeepBook V3 provides an onchain order book on Sui for spot trading and prediction markets. Spot orders from multiple apps route through the same book. Predict allows custom price levels, range positions, and timeframes from one minute to two weeks, with a shared pool taking the other side. It offers API, SDK, and indexer endpoints for orders and market data, with self-custodial onchain settlement where funds remain in the wallet until fill.

Access is limited: Predict currently supports only BTC and is not available to US users, and the trading platform is excluded in Afghanistan, Belarus, China, Cuba, Iran, North Korea, Myanmar, Philippines, Singapore, Russia, and Syria. Spot pairs depend on app expansion and users must check the app for current markets.
