+
+## Proposal summary
+
+This proposal updates existing price feeds for WETH, ARB, WBTC and USDC assets on the USDC.e market on Arbitrum.
+
+Further detailed information can be found on the corresponding [proposal pull request](https://github.com/compound-finance/comet/pull/1078) 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 is set to Compound DAO multisig: 0xb3e79c7cac540ca833015e63d96d3032ba0c4129.
+
+## Proposal actions
+
+The first action updates WETH, ARB, WBTC and USDC price feeds to the SVR implementation. This sends the encoded 'updateAssetPriceFeed' and 'deployAndUpgradeTo' calls across the bridge to the governance receiver on Arbitrum.
