Compound Crashes Leads To Users Getting ETH Locked For 7 Days

Market-leading lending protocol DeFi, Compound Finance, has just launched a proposal to upgrade its Chainlink price index. However, this code has an error and leads to some unnecessary problems.

This code makes it impossible for users who are lending or borrowing cETH (Compound ETH) to roll back their transactions. This means that users cannot borrow or withdraw collateral. Because of the above incident, users need to load in other types of assets to avoid liquidating existing loan positions.

According to an update from Security Solutions Architect Michael Lewellen of OpenZeppelin, the code bug came from the “getUnderlyingPrice” function, which did not update the price of cETH tokens, would return empty bytes and cause the call to be reverted.

“The primary issue right now is a temporary denial of service for the cETH market which will be resolved by the new governance proposal. No funds are at risk at this time. The rest of the cToken markets on Compound V2 and all of V3 remain functional,” Lewellen said.

The above error code caused the front end of Compound to stop working temporarily. Very soon, around 8 pm UTC on August 30, the protocol relaunched the front end normally. Compound founder Robert Leshner said on Discord:

“No funds seem immediately at risk. It will likely be seven days until cETH is functioning normally. There will potentially be more governance proposals to rectify the situation.”

Compound Labs reported that the coding flaw occurred despite the Oracle contract being reviewed by three independent smart contract auditing businesses, including OpenZeppelin and ChainSecurity, among the most recent firms to evaluate smart contracts.
