This proposal takes the governance steps recommended and necessary to initialize a Compound III USDC market on Linea; upon execution, cUSDCv3 will be ready for use. 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/deploy-compound-iii-on-linea/4460/19).\n\nFurther detailed information can be found on the corresponding [proposal pull request](https://github.com/compound-finance/comet/pull/953), [deploy market GitHub action run](https://github.com/woof-software/comet/actions/runs/13041520838/job/36384262627) and [forum discussion](https://www.comp.xyz/t/deploy-compound-iii-on-linea/4460).\n\n\n## ENS TXT record update\n\n[USDS on Base proposal](https://www.tally.xyz/gov/compound/proposal/395?govId=eip155:1:0x309a862bbC1A00e45506cB8A802D1ff10004c8C0) is active on the moment of pushing this proposal. The proposal reached the quorum and we expect that the proposal will be executed without fail. In case we need to cancel proposal 395, we need to cancel this proposal too\n\n## Proposal Actions\n\nThe first proposal action sets the Comet configuration, deploys a new Comet implementation, and sets the reward config on Linea. This sends the encoded `setConfiguration`, `deployAndUpgradeTo`, `setRewardConfig` calls across the bridge to the governance receiver on Linea.\n\nThe second action approves USDC tokens to the bridge.\n\nThe third action sends USDC tokens to the Linea chain via a special native USDC bridge.\n\nThe fourth action approves COMP tokens to the bridge.\n\nThe fifth action sends COMP tokens to the Linea chain via bridge.\n\nThe sixth action updates the ENS TXT record `v3-official-markets` on `v3-additional-grants.compound-community-licenses.eth`, updating the official markets JSON to include the new Linea cUSDCv3 market.';

This proposal takes the governance steps recommended and necessary to initialize a Compound III USDT market on Linea; upon execution, cUSDTv3 will be ready for use. 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/deploy-compound-iii-on-linea/4460/19).\n\nFurther detailed information can be found on the corresponding [proposal pull request](https://github.com/compound-finance/comet/pull/982), [deploy market GitHub action run](https://github.com/woof-software/comet/actions/runs/15211082351) and [forum discussion](https://www.comp.xyz/t/deploy-compound-iii-on-linea/4460).\n\n\n## Proposal Actions\n\nThe first proposal action sets the Comet configuration and deploys a new Comet implementation on Linea. This sends the encoded `setFactory`, `setConfiguration`, `deployAndUpgradeTo` calls across the bridge to the governance receiver on Linea.\n\nThe second action reduces Compound’s [cUSDT](https://etherscan.io/address/0xf650c3d88d12db855b8bf7d11be6c55a4e07dcc9) reserves and transfers it to Timelock, in order to seed the market reserves for the Linea cUSDTv3 Comet.\n\nThe third action approves 0 USDT from Timelock to [LineaL1TokenBridge](https://etherscan.io/address/0x051F1D88f0aF5763fB888eC4378b4D8B29ea3319) to reset potential previous approves.\n\nThe fourth action approves 100K USDT to [LineaL1TokenBridge](https://etherscan.io/address/0x051F1D88f0aF5763fB888eC4378b4D8B29ea3319) to take Timelock\'s USDT on Mainnet, in order to seed the market reserves through the bridge.\n\nThe fifth action bridges USDT from mainnet via Linea`s bridge contract and sends it to Comet on Linea.\n\nThe sixth action updates the ENS TXT record `v3-official-markets` on `v3-additional-grants.compound-community-licenses.eth`, updating the official markets JSON to include the new Linea cUSDTv3 market.';

This proposal takes the governance steps recommended and necessary to initialize a Compound III WETH market on Linea; upon execution, cWETHv3 will be ready for use. 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/deploy-compound-iii-on-linea/4460/20).\n\nFurther detailed information can be found on the corresponding [proposal pull request](https://github.com/compound-finance/comet/pull/982), [deploy market GitHub action run](https://github.com/woof-software/comet/actions/runs/15211470652) and [forum discussion](https://www.comp.xyz/t/deploy-compound-iii-on-linea/4460).\n\n\n## wrsETH Price Feed\n\n[wrsETH/ETH exchange rate](https://lineascan.build/address/0xEEDF0B095B5dfe75F3881Cb26c19DA209A27463a#readContract) price oracle has a wrong label. The information is confirmed with ChainLink and Kelp teams internally.\n\n\n## Proposal Actions\n\nThe first proposal action sends ether to the Linea Timelock so it can be wrapped and used to seed the reserves, sets the Comet configuration and deploys a new Comet implementation on Linea. This sends the encoded `setFactory`, `setConfiguration`, `deployAndUpgradeTo` calls across the bridge to the governance receiver on Linea.\n\nThe second action updates the ENS TXT record `v3-official-markets` on `v3-additional-grants.compound-community-licenses.eth`, updating the official markets JSON to include the new Linea cWETHv3 market.'; + const txn = await

This proposal takes the governance steps recommended and necessary to initialize a Compound III USDT market on Linea; upon execution, cUSDTv3 will be ready for use. 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/deploy-compound-iii-on-linea/4460/19).\n\nFurther detailed information can be found on the corresponding [proposal pull request](https://github.com/compound-finance/comet/pull/982), [deploy market GitHub action run](https://github.com/woof-software/comet/actions/runs/15211082351) and [forum discussion](https://www.comp.xyz/t/deploy-compound-iii-on-linea/4460).\n\n\n## Proposal Actions\n\nThe first proposal action sets the Comet configuration and deploys a new Comet implementation on Linea. This sends the encoded `setFactory`, `setConfiguration`, `deployAndUpgradeTo` calls across the bridge to the governance receiver on Linea.\n\nThe second action reduces Compound’s [cUSDT](https://etherscan.io/address/0xf650c3d88d12db855b8bf7d11be6c55a4e07dcc9) reserves and transfers it to Timelock, in order to seed the market reserves for the Linea cUSDTv3 Comet.\n\nThe third action approves 0 USDT from Timelock to [LineaL1TokenBridge](https://etherscan.io/address/0x051F1D88f0aF5763fB888eC4378b4D8B29ea3319) to reset potential previous approves.\n\nThe fourth action approves 100K USDT to [LineaL1TokenBridge](https://etherscan.io/address/0x051F1D88f0aF5763fB888eC4378b4D8B29ea3319) to take Timelock\'s USDT on Mainnet, in order to seed the market reserves through the bridge.\n\nThe fifth action bridges USDT from mainnet via Linea`s bridge contract and sends it to Comet on Linea.\n\nThe sixth action updates the ENS TXT record `v3-official-markets` on `v3-additional-grants.compound-community-licenses.eth`, updating the official markets JSON to include the new Linea cUSDTv3 market.';

In that incident, the protocol needed + * to react quickly to compromised / risky collateral, but the only available control + * surface was the governance proposal system, which introduces latency and coordination + * overhead. + * + * To address this, Comet was extended with a dedicated collateral deactivation mechanism: + * - The `pauseGuardian` can immediately deactivate a collateral asset by index via + * `CometExt.deactivateCollateral(assetIndex)`. + * - Deactivation sets a bit in `deactivatedCollaterals` storage and, for the given asset: + * - marks the asset as deactivated in core `Comet` (`isCollateralDeactivated`), + * - pauses supply of that collateral (via `collateralsSupplyPauseFlags`), + * - pauses transfer of that collateral (via `collateralsTransferPauseFlags`). + * - Once the risk is understood and resolved, the `governor` can later reactivate the + * asset via `CometExt.activateCollateral(assetIndex)`, which: + * - clears the deactivation bit in `deactivatedCollaterals`, + * - unpauses supply and transfer for that asset. + * + * This design allows: + * - **Fast, operational safety response** (pauseGuardian can respond without waiting for a + * full governance proposal lifecycle). + * - **Granularity per asset** (deactivate / activate by asset index, without impacting + * other collaterals). + * - **Clear separation of roles**: + * - `pauseGuardian`: emergency, short-term safety actions (deactivation). + * - `governor`: long-term policy decisions and re-enabling assets (activation). + * + * @dev + * What is tested in this file: + * + * 1. **Collateral deactivation happy path** + * - The `pauseGuardian` can successfully call `deactivateCollateral(assetIndex)`. + * - The transaction emits: + * - `CollateralDeactivated(assetIndex)` to signal that the asset has been marked + * as deactivated in protocol storage. + * - `CollateralAssetSupplyPauseAction(assetIndex, true)` to signal that new supply + * of the asset is paused. + * - `CollateralAssetTransferPauseAction(assetIndex, true)` to signal that transfers + * of that collateral are paused. + * - The core `Comet` contract reflects the updated state: + * - `isCollateralDeactivated(assetIndex)` returns `true`. + * - `deactivatedCollaterals()` has the corresponding bit set. + * - `isCollateralAssetSupplyPaused(assetIndex)` and + * `isCollateralAssetTransferPaused(assetIndex)` both return `true`. + * + * 2. **Collateral deactivation failure modes** + * - Only the `pauseGuardian` may deactivate collateral: + * - Calls from `governor` (or any non-pauseGuardian address) revert with the + * `OnlyPauseGuardian` custom error. + * - Asset index bounds are enforced: + * - Using an out-of-range index (`MAX_ASSETS`) reverts with `InvalidAssetIndex`. + * + * 3. **Collateral activation happy path** + * - The `governor` can successfully call `activateCollateral(assetIndex)` to re-enable + * a previously deactivated asset. + * - The transaction emits: + * - `CollateralActivated(assetIndex)` to signal that the deactivation flag for the + * asset has been cleared. + * - `CollateralAssetSupplyPauseAction(assetIndex, false)` to signal that new + * supply is allowed again. + * - `CollateralAssetTransferPauseAction(assetIndex, false)` to signal that + * transfers are allowed again. + * - Core `Comet` state is updated: + * - `isCollateralDeactivated(assetIndex)` returns `false`. + * - `deactivatedCollaterals()` is updated to clear the corresponding bit. + * - `isCollateralAssetSupplyPaused(assetIndex)` and + * `isCollateralAssetTransferPaused(assetIndex)` both return `false`. + * + * 4. **Collateral activation failure modes** + * - Only the `governor` may activate collateral: + * - Calls from the `pauseGuardian` (or any non-governor address) revert with + * the `OnlyGovernor` custom error. + * - Asset index bounds are enforced: + * - Using an out-of-range index (`MAX_ASSETS`) reverts with `InvalidAssetIndex`. + * + * 5. **MAX_ASSETS scalability and coverage** + * - The suite constructs a protocol with `MAX_ASSETS` collaterals and iterates over + * all valid indices. + * - For each `assetIndex` in `[0, MAX_ASSETS - 1]`: + * - `deactivateCollateral(assetIndex)` is callable by the `pauseGuardian` and + * marks the asset as deactivated in `Comet` (`isCollateralDeactivated` is `true`). + * - `activateCollateral(assetIndex)` is callable by the `governor` and clears the + * deactivated flag (`isCollateralDeactivated` is `false`). + * - This proves that the deactivation / activation bitmaps and pause flags scale across + * the entire configured collateral set, including those whose bits are stored in both + * `assetsIn` and `_reserved` segments on the core contract side. + * + * Together, these tests ensure that after the wUSDM and deUSD incident: + * - the protocol has a robust, low-latency mechanism to quarantine risky collateral + * without waiting on governance, + * - the mechanism is correctly wired to both storage-level flags and high-level events, + * -
