The idea behind the build

A reply on X becomes an on-chain prediction. Yosuku connects that familiar interaction to DeepBook Predict on Sui, with an order book for execution and an oracle for settlement.

The build spans the consumer interface, Move contracts, and TypeScript integration. Its own Predict SDK exposes composable transaction builders, a typed indexer, and a pricing engine checked against chain state.

Yosuku placed second in the DeepBook track at Sui Overflow 2026. The testnet record in the lab’s engineering brief includes 120+ unique wallets and 659+ transactions. Those are testnet figures, not claims of trading volume or revenue.

Under the surface.
