OKX Web3 DEX Aggregator Halted as Part of Regulatory Compliance Efforts

Highlights:

• OKX halts its Web3 DEX aggregator following financial crime allegations.
• The exchange said the move will prevent further compromise via new upgrades.
• The trading platform announced it rolled out two new features for detecting hacks on its platform.

Seychelles-based crypto exchange has temporarily halted its Web3 Decentralized Exchange (DEX) aggregator. In a March 17 press release, the exchange said the pause aims to upgrade the system to prevent further misuse by hackers. This step also addresses recent financial crime allegations.

OKX stated:

“Over the past few days, we’ve faced targeted media attacks questioning our integrity and operations. While we usually stay focused on building and protecting the industry, we can’t ignore the fact that these attacks are happening at a time when we are actively fighting against financial crime.”

In the press release, OKX confirmed it detected coordinated attempts by North Korea’s Lazarus Group to exploit its Decentralized Finance (DeFi) services. The exchange also uncovered significant spikes in competitive attacks targeted toward discrediting OKX’s blockchain security efforts.

The trading platform also stressed the need to boost transparency by working closely with blockchain explorers to correct incomplete labeling. “Our goal is to ensure that explorers properly highlight the actual DEX processing trades rather than mistakenly identifying our aggregator as the point of trade,” OKX added.

OKX: After consulting with regulators, we made the proactive decision to temporarily suspend our DEX aggregator services. This move allows us to implement additional upgrades to prevent further misuse. Beyond that, we've already rolled out: A hacker address detection system for… https://t.co/0W7ed4XTL8

OKX Launches New Features to Address its Web3 DEX Aggregator Vulnerability

Alongside the pause, OKX rolled out two new features to address future security concerns. First, the exchange launched a hacker address detection system for its Web3 DEX aggregator. The second feature tracks scammers’ most recent addresses and blocks them on OKX’s Centralized Exchange (CEX) in real time.

The above measures will position the trading platform ahead of cyber thieves, protect customers, and rebuild trust. OKX appreciated users’ patience and urged them to dismiss ongoing attacks as deliberate attempts to undermine the trading platform’s good works.

OKX’s Recent Financial Crime Allegations

OKX’s latest financial crime accusations started earlier this month after Ben Zhou’s hacked fund executive summary. On February 21, Bybit lost approximately $1.5 billion in the largest crypto scam exploit. The hack incident was closely followed by the exchange’s CEO report on March 4.

In the detailed summary, Zhou explained that the Bybit hacker relied mainly on THORChain, a DEX platform, to swap most of the stolen Ethereum for Bitcoin. However, the scammer also moved some funds through platforms like ExCH and OKX Web3 Proxy. The CEO added that Bybit could still recover $65 million. However, it would need assistance from the OKX wallet team.

On March 12, Crypto2Community reported that European regulators are probing OKX for allegedly helping the Bybit hacker move $100 million in crypto. According to the publication, the trading platform risks losing its Markets in Crypto-Assets Regulation (MiCA) license if found guilty of facilitating the transactions.

Responding to the above claims, OKX said the allegations were false, adding it reacted appropriately to Bybit’s hack. First, the Seychelles-based exchange blocked related funds from entering its CEX. Second, OKX developed new hack detection features. The exchange also stated that no EU regulator is investigating it. OKX reiterated its commitment to providing efficient trading options for users, stressing that it does not facilitate or aid in moving suspicious funds.

The Bloomberg article is misleading. Like all other major crypto exchanges, OKX provides a self-custody wallet service/swap feature that serves as an aggregator to create efficiency for the users. When Bybit got hacked, we reacted in two ways. (1) We froze associated funds moving… https://t.co/HUUmA8W2eq
