01Summary

AISummary by Kvorumclaude-haiku-4-5

This proposal updates price feeds for liquid staking and restaking tokens (wstETH, ezETH, wrsETH, weETH, and rETH) on Optimism's Compound v3 markets (USDC, USDT, and WETH) by implementing the CAPO (Correlated Assets Price Oracle) mechanism, which has been audited by OpenZeppelin and is designed to safely track yield-bearing assets while protecting against price manipulation.

Type
contract upgrade

Key changes

  • Update wstETH price feed to CAPO implementation on USDC, USDT, and WETH markets(high)
  • Update ezETH price feed to CAPO implementation on WETH market(high)
  • Update wrsETH price feed to CAPO implementation on WETH market(high)
  • Update weETH price feed to CAPO implementation on WETH market(high)
  • Update rETH price feed to CAPO implementation on WETH market(high)
  • Deploy new CAPO price feed contracts and upgrade existing price feed references(high)

Notable concerns

  • Price feed updates require cross-chain bridge execution to Optimism via governance receiver
  • CAPO implementation is new and should be carefully monitored despite OpenZeppelin audit

Update price feeds in cUSDCv3, cUSDTv3 and cWETHv3 on Optimism with CAPO implementation.

Proposal summary

This proposal updates existing price feeds for wstETH on the USDC, USDT and WETH markets and ezETH, wrsETH, weETH, and rETH on the WETH market on Optimism.

CAPO summary

CAPO is a price oracle adapter designed to support assets that grow gradually relative to a base asset - such as liquid staking tokens that accumulate yield over time. It provides a mechanism to track this expected growth while protecting downstream protocol from sudden or manipulated price spikes. wstETH, ezETH, wrsETH, weETH, and rETH price feeds are updated to their CAPO implementations. Further detailed information can be found on the corresponding proposal pull request and forum discussion for CAPO.

CAPO audit

CAPO has been audited by [OpenZeppelin](https://www.comp.xyz/t/capo-price-feed-audit/6631, as well as the LST / LRT implementation here.

Proposal actions

The first action updates wstETH, ezETH, wrsETH, weETH, and rETH price feeds to the CAPO implementation. This sends the encoded 'updateAssetPriceFeed' and 'deployAndUpgradeTo' calls across the bridge to the governance receiver on Optimism.
