$100 Million Liquidated on Defi Protocol Compound Following Oracle Exploit

By Clark

Lenders on suburbanised finance (defi) protocol Compound on  got liquidated for a vast $103 million, consistent with analytics supplier Loanscan. This happened when what seems to be associate oracle exploit on the Dai stablecoin. An apparent error or malicious attack to the Dai-dollar-peg information provided by the Coinbase oracle pushed the value of the stablecoin to regarding $1.30 – a premium of thirty% – going some users on Compound under-collateralized.

Compound gets its valuation information from Coinbase professional. Now, once this happened, and supported the intrinsical protocol rules, this might solely mean one issue – forced liquidation of the borrower’s position.

According to Alex Svanevik, chief military officer of information analytics firm statesman, the liquidations affected the third-largest COMP farmer, WHO was liquidated for $46 million. Svanevik told business media that, “As so much as I will tell, Compound worked specifically because it ought to. however queries are asked regarding the oracle.”

Compound, the third-largest defi platform, permits users to borrow funds like Dai from one another. However, to borrow, a user is compelled to produce collateral that exceeds the quantity they’re borrowing – that means all loans ought to be over-collateralized. When the value of Dai spiked within the suspected oracle exploit, liquidations occurred as a result of the loans had become under-collateralized.

For example, if a Compound user borrowed the equivalent of $100 in Dai, so the value of the stablecoin rose to $1.30, it means that the user’s borrowed quantity has additionally accrued to $130. However, if the user has but this quantity in collateral, they might be thought-about under-collateralized. Compound can liquidate them.

This is the platform’s biggest liquidation however. In July this year, Compound saw $6.3 million value of liquidations in twenty four hours. Some observers criticized Compound for counting on a centralized platform like Coinbase for its worth feeds.

“It boggles my mind that we have a tendency to square measure in late 2020 and defi platforms square measure still prone to oracle attacks,” aforementioned one Twitter user @linkfrogposter. “This is why the Chainlink worth feeds [for example] uses multiple sources {of information|of information|of knowledge} (multiple freelance node operators and multiple freelance data providers). A median is then calculated.”
