+
+## Proposal summary
+
+This proposal updates the cbBTC price feeds in the Compound III AERO, USDC, USDS, and WETH markets on Base to use the new SVR price feeds.
+
+Further detailed information can be found on the corresponding [proposal pull request](https://github.com/compound-finance/comet/pull/1129) and [forum discussion for SVR](https://www.comp.xyz/t/request-for-proposal-rfp-oracle-extractable-value-oev-solution-for-compound-protocol/6786).
+
+### 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 on Base is set to Compound DAO multisig: 0xb3e79c7cac540ca833015e63d96d3032ba0c4129.
+
+## Proposal Actions
+
+The first action updates the cbBTC price feeds in the AERO and WETH markets.
+
+The second action updates the cbBTC price feeds in the USDC and USDS markets.`;
