This proposal takes the governance steps recommended and necessary to update a Compound III WETH market on Ethereum. Simulations have confirmed the market’s readiness, as much as possible, using the [Comet scenario suite](https://github.com/compound-finance/comet/tree/main/scenario). The new parameters include setting the risk parameters based on the [recommendations from Gauntlet osETH](https://www.comp.xyz/t/add-oseth-as-a-collateral-on-ethereum-mainnet/5272/2).\n\nFurther detailed information can be found on the corresponding [proposal pull request](https://github.com/compound-finance/comet/pull/871) and [forum discussion osETH](https://www.comp.xyz/t/add-oseth-as-a-collateral-on-ethereum-mainnet/5272).\n\n## Price feed\n\nChainlink does not have osETH/ETH price feed on their website, however, Chainlink team ensured us that this address is the native exchange rate [price feed](https://etherscan.io/address/0x8023518b2192FB5384DAdc596765B3dD1cdFe471)\n\n\n## Proposal Actions\n\nThe first action adds osETH asset as collateral with corresponding configurations.\n\nThe second action deploys and upgrades Comet to a new version.';
