Resubmit

This proposal is a resubmission of previously passed Proposal 526, as it was not executed on L2.

Original proposal: https://www.tally.xyz/gov/compound/proposal/526

Proposal summary

This proposal updates existing price feeds for WETH, USDC, cbETH and wstETH assets on the USDC market on Base.

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 price feed is updated to their CAPO implementations.

SVR summary

RFP process and community vote passed and decided to implement Chainlink's SVR solution for BASE markets, this proposal updates WETH and USDC price feeds to support SVR implementations.

Further detailed information can be found on the corresponding proposal pull request, forum discussion for CAPO and forum discussion for SVR.

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.

SVR fee recipient

SVR generates revenue from liquidators and Compound DAO will receive that revenue as part of the protocol fee. The fee recipient for SVR is set to Compound DAO multisig: 0xd9496F2A3fd2a97d8A4531D92742F3C8F53183cB.

Proposal actions

The first action updates WETH, USDC, cbETH and wstETH price feeds to the CAPO and SVR implementations. This sends the encoded 'updateAssetPriceFeed', 'setBaseTokenPriceFeed' and 'deployAndUpgradeTo' calls across the bridge to the governance receiver on Base.
