Defillama Delists Aster Perp Volumes Over Suspected Wash Trading

Defillama has delisted perpetual futures volumes from Aster after its founder, 0xngmi, said recent Aster perp volumes began mirroring Binance perp volumes “almost exactly,” raising concerns about possible wash trading.

In a post explaining the decision, 0xngmi showed comparative charts for XRPUSDT volume on Aster and Binance with a near-1:1 volume ratio, versus a more decorrelated profile on Hyperliquid, and said Aster does not provide the lower-level order data needed to verify whether trades are genuine, prompting the temporary removal until that data can be obtained. In a follow-up thread addressing user criticism, 0xngmi defended the delisting as necessary to preserve data integrity, rejecting claims that Defillama was paid to delist Aster and noting the timing followed a sharp recent volume spike that triggered an investigation. He said Defillama has previously delisted other perp DEXs for suspected wash trading, explained past attempts to delist quietly had generated conspiracy claims, and added that keeping Aster listed with a warning would distort aggregate perp metrics and API users’ data unless the platform changes how it handles flagged feeds.
