This proposal takes the governance steps recommended and necessary to update a Compound III WETH market on Base. 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 off of the [recommendations from Gauntlet](https://www.comp.xyz/t/add-rseth-as-collateral-on-arbitrum-and-wrseth-as-collateral-on-optimism-base-and-scroll/5445/5).\n\nFurther detailed information can be found on the corresponding [proposal pull request](https://github.com/compound-finance/comet/pull/914) and [forum discussion](https://www.comp.xyz/t/add-rseth-as-collateral-on-arbitrum-and-wrseth-as-collateral-on-optimism-base-and-scroll/5445).\n\n\n## Proposal Actions\n\nThe first proposal action adds wrsETH to the WETH Comet on Base. This sends the encoded `addAsset` and `deployAndUpgradeTo` calls across the bridge to the governance receiver on Base.'; + const txn = await govDeploymentManager.retry(async () => + trace( + await governor.propose(...(await proposal(mainnetActions, description))) + ) + ); + + const event = txn.events.find( + (event) => event.event === 'ProposalCreated' + ); + const [proposalId] = event.args; + trace(`Created proposal ${proposalId}.`); + }, + + async enacted(deploymentManager: DeploymentManager): Promise { + return true; + }, + + async verify(deploymentManager: DeploymentManager) { + const { comet, configurator } = await deploymentManager.getContracts(); + + const wrsETHAssetIndex = Number(await comet.numAssets()) - 1; + + const wrsETHAssetConfig = { + asset: WRSETH_ADDRESS, + priceFeed: newPriceFeedAddress, + decimals: 18, + borrowCollateralFactor: exp(0.88, 18), + liquidateCollateralFactor: exp(0.91, 18), + liquidationFactor: exp(0.96, 18), + supplyCap: exp(230, 18), + }; + + // 1.
