GFX Labs put out Proposal 117 on behalf of Chainlink, which centers on creating a new price oracle. It upgraded the anchor market from Uniswap v2 to v3 and requested an upgrade of the protocol's oracle contract to version 3. With no votes against it, it gets approved without dissent.
The team announced that until proposal 119 takes effect, the cETH market would be frozen. The latter restores the old price feed. Compound Labs states that although it will take seven days for this to effect, funds are not at risk immediately.
On August 31, they said that users need to continue to be able to provide collateral, including Ether. Any interface problems need to resolve soon. Michael Lewellen, Architect for OpenZeppelin Security Solutions, stated that the Underlying Price function caused the problem. He said that because the value of cETH tokens did not update, it had reverted and returned empty bytes.
It is not the first time that Compound Finance has experienced a glitch. A "one-letter software fault" in October 2021 led to the unintentional payment of $90 million. No money was at risk because of the occurrence.
