DeFi just went through one of its roughest weeks on record. A single exploit on April 19 cascaded into a system-wide liquidity shock that pulled $15 billion in deposits out of Aave in three days, a 33% drop in total value locked from roughly $45 billion to $30 billion. According to XWIN Research Japan, the pace of the exit does not look like orderly risk management. It looks like fear.
The Kelp DAO Exploit That Started It
The event began at Kelp DAO, where an attacker identified a critical flaw in the protocol’s collateral system. Under normal conditions, rsETH is minted when a user deposits ETH as staking collateral, functioning as a receipt backed 1-to-1 by the underlying asset. The design is straightforward: deposit real ETH, receive a token representing it.
The attacker bypassed the deposit requirement entirely. By exploiting a flaw in the system, they minted rsETH without depositing any ETH at all, creating tokens that looked legitimate but were backed by nothing. Those tokens were then deposited as collateral on Aave, one of DeFi’s largest lending protocols, and used to borrow real assets including ETH and stablecoins. The result was up to $230 million in potential bad debt sitting inside a protocol that had no role in creating it. The exploit itself lasted hours. The damage it triggered is still unfolding.
The Numbers Behind the Liquidity Withdrawal
The market responded across the system simultaneously. It was not a single metric cracking. It was most of them cracking at once.
| Metric | Before Exploit | After Three Days |
|---|---|---|
| Aave total value locked | $45 billion | $30 billion |
| USDT / USDC borrow rate | ~3.4% | ~14% |
| USDe supply | Baseline | Contracted 14% |
| AAVE token price zone | Above $115 | $90 to $95 |
Borrowing rates for USDT and USDC surged from roughly 3.4% to 14% as demand for liquidity spiked against a shrinking supply of available capital. Holders began moving AAVE tokens onto exchanges at elevated rates, confirming that insiders were driving the selling pressure rather than simply marking positions down. USDe supply contracted 14% over the same three-day window, reflecting reduced demand and continued capital withdrawal from the broader DeFi ecosystem.
A Confidence Problem, Not a Price Problem
The speed and shape of the exit point to something more serious than a price correction. Capital is leaving DeFi not because prices fell, but because the event raised doubts about whether the protocols users trusted were adequately designed to prevent exactly this kind of outcome. When a receipt token with no underlying collateral can be used to borrow real assets on a blue-chip lending market, the problem is structural, not cosmetic.
XWIN Research Japan frames the recovery challenge in plain terms: the issue is not volatility, it is trust. Stronger protocol security, better collateral diversification, and more resilient liquidity design are the prerequisites, but none of them matter until users believe the system has genuinely changed. In DeFi, trust is not a soft metric. It is the entire foundation.
AAVE Price Struggles to Stabilize
The token has been trading under a clear bearish structure since late 2025, printing a persistent sequence of lower highs and lower lows. The latest move reinforces that weakness. AAVE briefly pushed toward the $110 to $115 area, testing the declining 50-day moving average, but was rejected quickly and sold back into its prior range. Both the 50-day and 100-day moving averages are trending downward, capping upside momentum.
Volume behavior adds context. The spike in selling volume during the drop back toward $90 suggests active distribution rather than passive drift. Buyers have stepped in around this level multiple times, establishing it as short-term support, but the lack of follow-through on rebounds points to limited conviction. If $90 fails to hold, the structure opens the door to a deeper move toward the $80 region. On the upside, AAVE would need to reclaim $110 with strength to begin challenging the broader downtrend. Until then, rallies look corrective rather than structural.
