# Update price feeds in cUSDCv3 on Base with CAPO and SVR price feeds.
## 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](https://www.comp.xyz/t/oev-rfp-process-update-july-2025/6945) and community [vote](https://snapshot.box/#/s:comp-vote.eth/proposal/0xffd84200f112926e8b21793ee3750f272fc40a3f90399f86d41971a44aa3edf3) 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](https://github.com/compound-finance/comet/pull/1074), [forum discussion for CAPO](https://www.comp.xyz/t/woof-correlated-assets-price-oracle-capo/6245) and [forum discussion for SVR](https://www.comp.xyz/t/request-for-proposal-rfp-oracle-extractable-value-oev-solution-for-compound-protocol/6786).
### 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](https://www.comp.xyz/t/capo-lst-lrt-audit/7118).
### 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.
