This proposal takes the governance steps recommended and necessary to update a Compound III USDC 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/gauntlet-wsteth-and-ezeth-asset-listing/5404/1).\n\nFurther detailed information can be found on the corresponding [proposal pull request](https://github.com/compound-finance/comet/pull/889) and [forum discussion](https://www.comp.xyz/t/gauntlet-wsteth-and-ezeth-asset-listing/5404).\n\n\n## Proposal Actions\n\nThe first proposal action adds wstETH to the USDC Comet on Base.
