OKX has relaunched its decentralized exchange (DEX) aggregator, OKX Web3, following a temporary shutdown in March that aimed to halt exploitation by the North Korean-linked hacking group Lazarus.
OKX founder and CEO Star Xu announced the platform’s return, emphasizing that the relaunch comes with significant security upgrades. Chief among them is a real-time monitoring system designed to detect and block malicious activity as it occurs, aiming to protect users from on-chain threats.

Functionally, a DEX aggregator collects pricing and liquidity data from various decentralized exchanges and market makers to help users secure optimal trading outcomes. Highlighting OKX’s broader vision, Xu described OKX Web3 as “a browser and search engine for blockchain,” reflecting its role in making decentralized finance more accessible and user-friendly.
The exchange detailed additional security enhancements in a separate announcement on May 4. These include advanced tools that identify real-time suspicious or fraudulent blockchain activity.
“Our dynamic database of suspect addresses blocks hackers and bad actors in real-time, while proactive alerts warn users about potentially risky transactions,”
OKX stated.
To further bolster trust, OKX underlined its transparency and security credentials, noting that its systems have been audited by leading blockchain security firms such as CertiK, Hacken, and SlowMist. Additionally, its infrastructure has undergone rigorous testing through a dedicated bug bounty program.
In March, OKX paused its DEX aggregator to prevent what was described as “further misuse” by the Lazarus Group. At the time, it pledged to build a system capable of tracking hacker-associated addresses and automatically blocking them from engaging with the platform.
Meanwhile, in a major development, OKX has officially re-entered the United States market. The return comes just months after resolving a $500 million case with the U.S. Department of Justice. Alongside its comeback, the company has launched a revamped trading platform and a new self-custody Web3 wallet and introduced fresh leadership, signalling a strategic reboot in one of the world’s most critical crypto markets.
