You didn’t touch Aave. You didn’t even use the protocol that got hacked. But if you had money sitting in DeFi that week, you still felt it.
Here’s what happened.
A protocol called KelpDAO got exploited for $293 million. The attackers took a token called rsETH, which had lost its backing, and used it as collateral on Aave to borrow real money. Aave never got hacked. Its code did exactly what it was built to do. But once people saw “exploit” and “Aave” in the same sentence, they stopped reading the details.
Within four days, depositors pulled $12 billion out. Nearly half the platform was gone. Not because Aave was broken, but because everyone rushed for the exit at the same time.
This is what “contagion” actually looks like in crypto. Your funds don’t need to be in the hacked protocol to get hurt. They just need to be sitting near it.
“In DeFi, your biggest risk is rarely the protocol you chose. It’s the ten protocols quietly connected to it. Know what your money is standing next to.”
Beginners often think diversification means spreading money across different tokens.
But real risk in DeFi is about connections – which protocols borrow from each other, which collateral backs which loan. When one link snaps, the panic doesn’t ask permission before spreading.
The traders who lost the most here weren’t the ones who understood the exploit.
They were the ones who understood it last — and pulled out after the damage was already priced in, locking in losses that patience might have avoided.
