A "whale" is repeatedly causing interest rate spikes on Aave's USDC pool by temporarily withdrawing nearly $190 million in liquidity every night around 23:30 UTC and returning it within an hour. This action, tracked to a specific Ethereum address, spikes the pool's utilization above its 92% target, sharply increasing variable borrowing rates for all users in the pool during that window. Analysis suggests this is likely a fund performing a daily compliance ritual—withdrawing funds to prove ownership for a snapshot before redepositing them. While the time window for these withdrawals has tightened from June to July, the practice imposes a significant cost. Calculations show this activity costs borrowers in the pool an extra $1.7 million per year. For context, a single $1 million loan incurs about $3,280 in extra annual interest. The transparency of DeFi exposes how traditional financial compliance processes can create a hidden tax for decentralized finance users, highlighting a need for adapted regulatory frameworks.
