What happened last night?

1 There was a bug in the Ethereum programming language.

2 This bug led to the attack on Curve.

3 The price of CRV on the chain fell to 0.08, but Link was not updated in time. If even Aave and DeFi projects were affected, the situation would be even worse.

4 Fortunately, projects such as Uniswap used an old version of the language, otherwise the consequences would be more serious.
