Overview
OpenZeppelin reviewed Proposal 456, submitted by WOOF!, which proposes adding pufETH as collateral to the WETH market on Ethereum.
Medium Severity
PriceFeedWith4626Support Used Instead of CAPO Price Feed
The current proposal uses a PriceFeedWith4626Support price feed for pufETH. However, since pufETH is an nLRT that appreciates relative to ETH, using a CAPO price feed would offer stronger protection against price manipulation attacks.
Consider using the audited CAPO price feed for the pufETH collateral, as well as for any future LSTs that may benefit from the same security guarantees.
Conclusion
The review identified an opportunity to integrate a CAPO price feed for pufETH to enhance protection against price manipulation attacks. Aside from this, the proposal’s description and actions are accurate and align with Gauntlet’s recommendations for the collateral.
