How do hackers launder money?

Money laundering is generally divided into three stages: placement, layering, and integration.

The smart splitting algorithm of OKX DEX may be mainly used in the "layering" stage.

The smart splitting algorithm will automatically split large transactions into multiple small orders and disperse them to different liquidity pools and blockchain networks, such as from Ethereum to Polygon or Arbitrum.

This decentralization increases the difficulty of blockchain analysis, because the funds are divided into multiple small transactions and scattered across different addresses and networks, making it complicated to track the complete flow of funds.

More importantly, the average daily trading volume of OKX DEX exceeds US$200 million, providing a natural "noise" environment.
