Lenders on decentralized finance (defi) protocol Compound on Thursday acquired liquidated for a large $103 million, in response to analytics supplier Loanscan. This occurred after what seems to be an oracle exploit on the Dai stablecoin.
An obvious error or malicious assault to the Dai-dollar-peg knowledge equipped by the Coinbase oracle pushed the value of the stablecoin to about $1.30 – a premium of 30% – leaving some customers on Compound under-collateralized.
Compound will get its pricing knowledge from Coinbase Professional. Now, as soon as this occurred, and primarily based on the built-in protocol guidelines, this might solely imply one factor – compelled liquidation of the borrower’s place.
In accordance to Alex Svanevik, chief government officer of information analytics agency Nansen, the liquidations affected the third-largest COMP farmer, who was liquidated for $46 million.
