April 18th, KelpDAO was hacked.

It's not the kind of "small injury, small pain" vulnerability; it's a direct face-riding output— the attacker minted 116k rsETH out of thin air, threw it into Aave, and borrowed $190 million.

Aave's bad debt is conservatively estimated at $123 million, and more broadly, $230 million.

TVL evaporated by $6.6 billion in one day.

Do you think it's just another project going to zero?

No.

In the next 48 hours, DeFi staged the most daring move in crypto history:

Lido said: I will provide 2,500 stETH.

Mantle said: I will borrow 30,000 ETH.

Aave founder Stani personally put in 5,000 ETH.

Let's review what happened.

KelpDAO's bridging contract was attacked, and rsETH was minted out of thin air.

These "fake coins" entered Aave, borrowing real funds.

Aave's account showed bad debt, and the rsETH gap was there.

If not replenished:

- Aave depositors won't get their money back.

- Trust in the entire LRT track collapses.

- Next, a chain of liquidations begins, like dominoes falling one after another.

So Stani stepped up.

"I donate 5,000 ETH to DeFi United."*

What is DeFi United?

It's not a foundation, not a DAO, but a temporary "rescue team" formed by top protocols.

Lido, Mantle, Aave... usually each king in their own domain, today sitting at one table.

It’s very much like a mafia movie meeting of gang leaders:

“This time, everyone pitches in to fill the hole.”

Is this warmth, or a tactic?

You call this "DeFi community spirit"?

I believe it.

But I also want to say:

They’re not saving Kelp; they’re saving themselves.

Think about it: if the rsETH gap isn’t replenished—

Aave becomes a bad debt bank, who would dare to deposit?

Lido’s stETH is a core collateral on Aave; lock liquidity, and Lido halves its value.

Mantle? It’s desperately pushing its ecosystem; collapsing an LRT now would wipe out market confidence.

So this isn’t charity.

It’s the collective self-rescue of leading players in the ecosystem.

Why is this event worth your attention?

Because if they succeed this time, DeFi will enter a new phase:

- Protocols will no longer just compete but will "back each other up."

- A single vulnerability no longer means a chain-wide collapse, because the big players will sit down and talk.

- Bad debt can be internally absorbed by the "protocol alliance," rather than making users pay.
