Update price feeds in cUSDCv3 on Mainnet with CAPO and Chainlink SVR implementation.

Proposal summary

This proposal updates existing price feeds for wstETH, WBTC, WETH, LINK, rsETH, weETH and COMP on the USDC market on Mainnet.

SVR summary

RFP process and community vote passed and decided to implement Chainlink's SVR solution for Mainnet markets, this proposal updates wstETH, WETH, WBTC, LINK, rsETH, weETH and COMP price feeds to support SVR implementations.

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, rsETH and weETH price feeds are updated to their CAPO 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, 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.
