- CZ proposes DeFi dark pools to shield billion-dollar trades from MEV bots and predatory front-running on transparent DEX order books.
- $100M Hyperliquid liquidation exposes whales: Transparent perpetual DEXs let attackers hunt stop-losses like James Wynn’s BTC position.
Binance co-founder Changpeng “CZ” Zhao recently suggested a dark pool perpetual swap decentralized exchange. The goal is to shield large trades from front-running and MEV bot attacks. At a glance, the idea seems straightforward. Yet, the mechanics and risks run deep.
Transparent DEXs display all orders in real time. If someone tries to buy $1 billion of a token, bots and other traders spot the intent immediately. Consequently, they jump ahead in the order flow.
As a result, the big buyer ends up paying extra. Moreover, on perpetual DEXs, liquidation levels are open for all to see. Bad actors can push prices close to those thresholds. Then, they trigger mass liquidations for profit.
Consider the recent $100 million liquidation on Hyperliquid
Trader James Wynn held nearly $100 million in long BTC positions. When Bitcoin dipped below $105,000, the positions were wiped out. Rumors on social media pointed to a coordinated “liquidation hunt.” Some even claimed high-profile figures showed interest. Although none of those claims are proven, the episode highlights how exposed big traders remain on transparent platforms.
Dark pools have existed in traditional finance for years. They let large players trade without revealing orders to the public. In fact, CZ noted that some dark pools are ten times larger than regular venues. By operating in private, traders avoid front-running, slippage, and unnecessary price swings. Translating that model into DeFi, however, presents unique challenges.
StealthEX CEO Maria Carola explained that any DeFi dark pool must balance privacy with verifiability. She mentioned zero-knowledge proofs such as zk-SNARKs or zk-STARKs. These tools let a system confirm a trade without exposing details.
Still, she warned that hiding orders can also hide manipulative schemes, especially in leveraged markets. Therefore, she recommended adding risk engines and behavior-monitoring tools. In short, if you cloak trades, you must also build safeguards to spot hidden danger.
CZ does not claim this model is foolproof
He pointed out that transparency helps market makers absorb large orders. Hence, some openness can be useful. Yet, he invited developers to explore on-chain dark pool designs. For example, they could mask the order book or delay deposit visibility. By doing so, DEXs might offer a safer space for institutional-scale trading.
Given recent events, I think now might be a good time for someone to launch a dark pool perp DEX.
I have always been puzzled with the fact that everyone can see your orders in real-time on a DEX. The problem is worse on a perp DEX where there are liquidations.
Even with a CEX…

At the same time, regulators and ordinary users will watch closely. A truly private trading venue could draw scrutiny if it shields illicit activity. Moreover, the technical complexity may slow adoption. Smaller traders might stick with familiar DEXs that offer clear price discovery. Meanwhile, whales and hedge funds could test the dark pool model in hopes of better execution.
