How scoring works →Summary
OKX DEX is the decentralized exchange aggregator operated by OKX (Aux Cayes FinTech Co. Ltd.), one of the world's largest centralized crypto exchanges. In December 2023, the DEX suffered a ~$2.7 million exploit caused by a suspected private key leak and a centralized proxy upgrade mechanism with no multi-signature protection. The broader OKX entity has faced severe regulatory sanctions including a $504 million U.S. DOJ settlement in February 2025 for operating an unlicensed money-transmitting business and facilitating over $5 billion in suspicious transactions, a €1.1 million Malta AML fine, and repeated scrutiny over its DEX aggregator being used by North Korea's Lazarus Group to launder stolen funds from the $1.5 billion Bybit hack in early 2025.
