Sui news today is centered on the September 24 launch of DeepBook App, a new trading interface giving users direct access to the shared onchain order book that has supported more than $20 billion in trading volume across the Sui ecosystem. The DeepBook Trading Foundation said the application combines spot trading and prediction markets in one interface. The app is designed to provide direct access to markets available through the DeepBook protocol, with additional trading pairs potentially added as support expands.
