| const description = '# Add wUSDM as collateral into cUSDTv3 on Optimism\n\n## Proposal summary\n\nCompound Growth Program [AlphaGrowth] proposes to add wUSDM into cUSDTv3 on Optimism network. This proposal takes the governance steps recommended and necessary to update a Compound III USDT market on Optimism. 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-wusdm-as-a-collateral-on-usdc-usdt-markets-on-optimism/5664/4).\n\nFurther detailed information can be found on the corresponding [proposal pull request](https://github.com/compound-finance/comet/pull/945) and [forum discussion](https://www.comp.xyz/t/add-wusdm-as-a-collateral-on-usdc-usdt-markets-on-optimism/5664).\n\n\n## Proposal Actions\n\nThe first proposal action adds wUSDM to the USDT Comet on Optimism. This sends the encoded `addAsset` and `deployAndUpgradeTo` calls across the bridge to the governance receiver on Optimism.'; | ||
