Blockchain analytics firm Bitquery reports that an unidentified crypto whale has repeatedly withdrawn approximately $290 million in USDC from Aave and Sky platforms for 394 consecutive midnights (UTC) since September 30, 2025, with $134 million originating from Aave. This action temporarily depleted liquidity, causing Aave's USDC lending rate to surge from 4.5% to 13.8%, nearly tripling. The funds typically returned after about half an hour. Bitquery noted that these repeated operations caused Aave's USDC lending pool utilization to rise from a median of 94% to 99.6% in October, reaching 100% on six nights. However, Aavescan data shows that the lending rate had fallen back to 5.45% at midnight UTC on October 29, indicating an easing of the liquidity crunch.
