Decentralised finance (DeFi) analytics platform DeFiLlama delisted perpetual futures volume data from Aster, a fast-rising decentralised exchange (DEX), after spotting suspicious trading patterns mirrored Binance’s market activity. Aster had recently ranked among the top DEXs for daily fees and volume, and hence, this decision has brought more attention to questions on transparency in the DeFi space. Aster’s native token, ASTER, fell more than 10 percent, underscoring investor anxiety about the platform’s credibility.
Suspicious Trading Patterns Spark Transparency Debate
In a detailed post on X, DefiLlama’s pseudonymous founder (0xngmi) explained their decision, stating that pairs like XRP/USDT and ETH/USDT on Aster showed trading volumes that were almost identical to Binance’s perpetual futures contracts. He contended that the degree of correlation was statistically unlikely in natural market circumstances, suggesting that Binance’s liquidity might be replicated synthetically or through wash trading.
We’ve been investigating aster volumes and recently their volumes have started mirroring binance perp volumes almost exactly

Aster’s failure to provide detailed order-level data caused worries by making it impossible for analysts to confirm the authenticity of the reported trading volumes. Crypto markets have long suffered from wash trading, a practice in which trades cancel each other out to produce inflated volume metrics.
DefiLlama was not compensated to delist Aster, and the team has no financial stake in either Aster or its competitor Hyperliquid, 0xngmi clarified in response to rumours.
Thread going over all the complaints that ppl had about the aster delisting:
1. Why not just report data as is, your job is just to report it?
Our users trust our data and make investing decisions based on it, if we report incorrect data they’ll make the wrong decisions

Aster has previously been questioned over its reporting of digital assets. The DEX was previously criticised for inflating revenue figures by incorporating user rebates. This incident fuelled conspiracy theories about “backroom deals,” even though it had led to a silent delisting from DefiLlama.
The most recent action has sparked controversy, particularly since Changpeng “CZ” Zhao, a co-founder of Binance, is one of Aster’s advisors. Zhao and Aster have not made any public remarks regarding the matter.
Aster is moving forward with its roadmap despite the controversy. The Stage 3 “Aster Dawn” update, which will add new reward systems, is about to be released on the platform. Four percent of its entire supply, or about 320 million tokens, will also be released during an upcoming airdrop event without a vesting period.
Although investor confidence may remain brittle until issues with data integrity are addressed, these developments, along with continued whale activity, could still have an impact on ASTER’s market dynamics.
