DeepBook & DeepBook Predict — Building Real Markets on Sui's Onchain Orderbook
On most chains, an on-chain orderbook is a fantasy. Gas eats the spread, latency makes professional makers flee, and what's left is an AMM pretending. Sui's object model and DeepBook v3 changed the math — sub-cent fees, atomic settlement, real limit orders fully on-chain. Now layered on top is DeepBook Predict: binary prediction markets, a $70K Overflow 2026 track, and one of the least-crowded prize pools in the competition. This session takes you through DeepBook v3 from architecture to TypeScript SDK, then goes deep on Predict — the Move module, the resolution model, and the three viable hackathon build paths most teams aren't exploring yet. You'll leave with a working Predict integration on testnet, a clear-eyed view of where the actual technical risk lives, and a build plan you can ship before June 21.
What You'll Learn
Why a real on-chain orderbook is possible on Sui specifically — object model, parallel execution, and what that changes
DeepBook v3 architecture: pools, BalanceManager objects, the DEEP fee model, and how the matching engine settles atomically
Running the full DeepBook stack locally via the deepbook-sandbox repo — one command, instant orderbook
The DeepBook TypeScript SDK in practice: placing limit and market orders, querying the book, cancelling, and reading state
DeepBook Predict end-to-end: binary outcome tokens, oracle-based resolution, and the entry functions in the Predict Move module
The three hackathon build paths on Predict — new market types, analytics dashboards, trading bots — and the honest tradeoffs of each
Who Should Attend
Sui developers planning to submit to Overflow 2026's DeepBook Predict or DeFi & Payments tracks
Backend engineers building trading infrastructure who want orderbook semantics without ETH-scale gas
Quant-minded builders interested in on-chain prediction markets and oracle design
Teams looking for a $70K track with lower historical submission volume than DeFi & Payments
