# Update price feeds in cUSDCv3 and cWETHv3 on Linea with CAPO implementation.
## Proposal summary
This proposal updates existing price feeds for wstETH on the USDC and WETH markets and ezETH, wrsETH, and weETH on the WETH market on Linea.
### 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, and weETH price feeds are updated to their CAPO implementations.
Further detailed information can be found on the corresponding [proposal pull request](https://github.com/compound-finance/comet/pull/1061) and [forum discussion for CAPO](https://www.comp.xyz/t/woof-correlated-assets-price-oracle-capo/6245).
### 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).
## Proposal actions
The first action updates wstETH, ezETH, wrsETH, and weETH price feeds to the CAPO implementation. This sends the encoded 'updateAssetPriceFeed' and 'deployAndUpgradeTo' calls across the bridge to the governance receiver on Linea.
