如何实现 Dex Aggerator

Question

如何在 Sui 上实现 DEX 聚合器，在多个 DEX（例如 Cetus、Turbos、Bluefin）之间动态路由代币互换，以实现最佳定价？具体而言，我应该如何设计路由逻辑，整合不同的池类型（恒定产品、稳定或集中的流动性），并在Sui Move中处理链上执行、滑点保护和气体效率？

It’s challenging to find a reference because the logic behind it is what makes the aggregator stand out by offering the best routing for swaps. But you can approach the concept (how they do) first then optimize aggerator later Routing Logic Scan DEXs: Collect liquidity data (reserves) for token pairs from different DEXs. Compare Prices: Check the prices for the same token pair across DEXs. Select Best Route: Choose the DEX offering the best price (lowest slippage). Atomic Transaction: Thanks to PTB (Programable Transaction Block) we could do this easily Gas Efficiency: Minimize the number of actions to reduce gas cost Slippage Protection User Input: Let users set a slippage tolerance Check Before Execution: Ensure the final price doesn’t exceed the user’s slippage tolerance before confirming the transaction. User Flow Example User wants to swap Token SUI for Token USDC. Aggregator checks prices: Looks at Cetus, Turbos, Bluefin for Token A → Token B price. Best route is selected: Chooses the DEX offering the best rate.
