NOTE: The biggest DeFi network attack of 2026 just occurred

AAVE, a protocol that everyone considers SAFE, has become stuck in a vortex, and its token has dropped by 20%. This is not a hack of Aave. But the damage is real.
👉On Saturday, April 18, an attacker exploited the Kelp DAO cross-chain bridge, a liquidity ETH staking protocol.
🔻The attacker impersonated a message and withdrew 116,500 rsETH (Kelp’s staking liquidity tokens) from the bridge contracts.
🔻Value at the time of attack: $292 million. 18% of the total circulating supply of the token.
🔻Kelp paused its multi-signature contracts for 46 minutes. But the damage had already been done.
🔻Kelp paused its multi-signature contracts for 46 minutes. But the damage had already been done.
🧨 And here is the part directly related to Aave:
🔻The attackers stole rsETH (which is now essentially worthless paper) and used it as collateral in Aave V3.
🔻Then, they borrowed $236 million USD using WETH based on that worthless collateral.
🔻When rsETH lost its 1:1 peg $ETH and its value, Aave had to bear the bad debt. Estimated bad debt: between $177 million and $200 million USD.
Why did Aave accept that collateral?
▪️Because DeFi is decentralized. Anyone can deposit any listed asset.
▪️The protocol has no human-controlled risk management team to ask, “Where does this token come from?”
▪️The code accepts whatever it is programmed to accept.
▪️That is the wonder of DeFi. And that is also its fatal flaw.
🩸 The immediate consequences are devastating:
▪️The $AAVE token dropped between 16% and 22%.
▪️The WETH pool reached 100% utilization. Lending interest rates skyrocketed. A rush to withdraw occurred.
▪️Aave immediately froze the rsETH market in V3 and V4.
▪️Other protocols (SparkLend, Fluid, Compound V3, Euler)also paused rsETH as a precaution.
🎯 The irony of the timing:
▪️This happened a few weeks after Aave launched V4 with its Hub & Spoke architecture, their most ambitious project in history.
▪️And the DAO just approved a $25 million grant to Aave Labs with the slogan “Aave will win.” The growth momentum was incredible.
▪️And then rsETH appeared.
👀Can Aave overcome this challenge?
📍Most likely yes. It has its Umbrella (insurance fund) module and a DAO community with extensive crisis management experience.
📍It has previously survived worse crashes, including the Terra/Luna collapse and the 2022 bear market, and now they say all losses will be compensated.
📍But the undeniable message it leaves behind is: in DeFi, there is no such thing as “too big to fail.”
