Crestmax

CrestMax is a next-generation decentralized market-making protocol built on Sui, designed to deepen liquidity, tighten spreads, and unlock sustainable yield for users. CrestMax introduces automated liquidity vaults that pool user assets and deploy adaptive market-making strategies directly on DeepBook, Sui’s on-chain orderbook.

By placing dynamic bid/ask orders, rebalancing inventory in real time, and capturing micro-spreads across market movements, CrestMax transforms thin, illiquid orderbooks into deep, efficient trading venues. Users deposit assets, receive vault shares, and earn passive yield generated from MM profits no active trading required.

CrestMax aims to become the liquidity backbone of Sui by making market-making accessible, automated, and composable for all DeFi participants.

CrestMax started with a focused investigation into the gaps within the Sui DeFi ecosystem. Through this research, we identified that DeepBook’s orderbooks often remain thin, causing large spreads and inefficient execution. Since no automated liquidity vaults or adaptive market-making systems existed on Sui, we set out to design a solution from scratch.

We studied market-making models from both traditional finance and modern DeFi to understand how automated vaults manage liquidity, risk and pricing. This research shaped the core architecture of CrestMax: an on-chain system that places dynamic bid and ask orders, monitors inventory balance and adapts in real time to market conditions. Along the way, we designed entirely new Move contract components that were missing in the ecosystem.

To make the strategy smarter, we integrated a lightweight ML agent that produces pricing signals and spread adjustments based on market patterns. These outputs flow directly into the strategy executor inside our Move modules, allowing the vault to refine its behavior using live signals rather than fixed parameters.
