The Unfolding Controversy Around Aster DEX: Accusations of Wash Trading and Market Reactions

Aster DEX Under Fire: Accusations of Wash Trading

Aster DEX (decentralized exchange) has recently come under scrutiny for alleged market manipulation and inflated trading volumes. The controversy began when Oxngmi, the founder of the data aggregation platform DeFiLlama, raised concerns about Aster’s trading data. He pointed out that Aster’s trading volumes exhibited a notable correlation with Binance’s perpetual contracts (perps), but diverged significantly from similar pairs on Hyperliquid. This raised eyebrows regarding the legitimacy of Aster’s trading practices, as it became evident that the DEX’s use of dark pools makes order information opaque and hard to verify. This lack of transparency led DeFiLlama to announce that it would delist Aster’s perpetual volumes until proper verification could be established.

Dark Pools and Their Implications

The dark pools employed by Aster DEX are designed for off-exchange trading, allowing orders to be matched without revealing the identity of the traders involved. While this can provide certain advantages, the downside is that it complicates the verification of trade data. Unlike its competitor, Hyperliquid, which does provide a clearer view of order flows, Aster’s structure raises suspicions over the integrity of its reported volumes. The allegations of wash trading—that is, buying and selling assets to create misleading volume—put Aster in a precarious position, particularly in a market where transparency is paramount for investor trust.

Market Reactions and Initial Impact

The backlash from DeFiLlama’s announcement prompted a swift market reaction. On October 5th, the price of Aster (ASTER) fell approximately 10%, plummeting from $2.10 to $1.70 before stabilizing around the $1.80 mark. This sell-off reflected immediate trader panic, but interestingly, the drop coincided with higher trading activity at lower price points. The last significant downturn prior to this had established a support zone between $1.50 and $1.65, which could act as a rebound point if defended by buyers.

Whale Activity Defies Selling Pressure

Despite the negative market sentiment following the delisting announcement, there are signs of resilience among Aster investors, particularly among large-scale investors often referred to as "whales." Recent on-chain data from Lookonchain revealed that a significant player acquired 1.69 million Aster tokens, valued at over $3.1 million, during the price dip. This kind of accumulation by large investors typically indicates confidence in the asset’s potential for recovery. Moreover, the overall selling pressure appears to be easing, suggesting that market participants are focusing on potential rebounds rather than panic selling.

Exchange Outflows and Future Potential

The aggregated data shows mixed signals about Aster’s current standing in the market. Since its debut last month, the exchange netflow of Aster has seen significant activity, with 77 million tokens moving toward on-chain exchanges for profit-taking. While this indicates some degree of volatility and profit realization among traders, recent trends show that the inflow of tokens has flattened, meaning selling pressure may be diminishing. This environmental shift presents an opportunity for potential rebounding, particularly if more whales continue to invest in Aster.

Volume Dominance and Revenue Insights

Despite the surrounding controversy, Aster DEX has demonstrated spectacular trading volumes—hitting $441 billion within just a week of October, achieving over 90% of the total decentralized exchange trading volume. Its trading performance in September, reported at $420 billion, nearly doubled that of its nearest competitor, Hyperliquid (which recorded $282 billion). This volume success not only indicates a solid user base but also generates significant revenue, exceeding $210 million in fees in the past month alone, positioning Aster DEX as the second-largest revenue-generating platform, following Tether (USDT).


The unfolding narrative surrounding Aster DEX raises essential questions around transparency and trust in the DeFi ecosystem. While accusations of wash trading create a shadow over Aster’s operations, whale activity suggests that savvy investors remain optimistic about long-term potential. As the market continues to react, stakeholders must navigate the delicate interplay of risk and opportunity inherent in trading on platforms like Aster DEX.
