Let's first look at the principle of OKX DEX's X Routing algorithm:

(1) Scan liquidity sources: obtain real-time liquidity data from multiple DEXs (such as Uniswap, Curve, etc.) and cross-chain bridges.

(2) Optimize transaction paths: calculate the optimal transaction route based on price, slippage and gas fees.

(3) Split orders: split large transactions into multiple small transactions and spread them to different liquidity pools or paths to reduce market impact and obtain the best execution price.

(4) One-time execution: complete all split sub-orders through a single blockchain transaction to ensure atomicity (that is, either all succeed or all fail).

We can find that the above design is very efficient, but these features can indeed be exploited by hackers.
