The Compound Lending Protocol has suspended lending and collateral withdrawals for cETH tokens after a bug was discovered in the activated Offer 117. The offer has updated the price streams for Compound v2.
The error leads to cancellation of transactions for ETH suppliers and borrowers. Code checked by OpenZeppelin, Dedaub and ABDK.
Some users acknowledged that developers contributed code after it was reviewed by code audit firms.
The team stated that there is no risk to user funds. The protocol still allows for collateral to be added, including Ethereum. The developers warned that the interface will be unavailable for a while due to “price inconsistencies”.
Proposal 117, on behalf of ChainLink, offered GFX Labs to upgrade their price feed oracle contracts from version 2 to version 3 of Uniswap.
“The main issue is the temporary shutdown of the CETH market, which will be resolved by a new governance proposal. No funds are currently at risk. The rest of the cToken markets in Compound V2 and all V3 markets remain functional.”— Described on OpenZeppelin.
An hour after the event, GFX Labs proposed Offer 119, which would cancel Offer 117. According to the governance process, it will take effect seven days after acceptance.
Mudit Gupta, Polygon’s head of information security, expressed disappointment at the prolonged quarantine.
“This is the second time in the last few months that Compound has broken for seven days. Temporary locks are not always good. Stop using awkwardly”said.
Issues with the update did not greatly affect the positions of the project management token. According to CoinGecko, over the past 24 hours, Compound has dropped 1.7% amid a mixed DeFi sector asset performance.
Recall that in September 2021, the project suffered millions of dollars in losses due to an error in updating the protocol.
