## Summary

The Morpho Association proposes to list sDAI and USDT as collateral only on the AaveV3-ETH Optimizer as it would unlock new usecases for sDAI and USDT holders.

## Abstract

The Morpho Labs’ team has carefully reviewed the implementation contracts and run [productions tests](https://github.com/morpho-org/morpho-aave-v3/blob/main/test/prod/TestProdLifecycle.sol) on a fork and [seatbelt tests](https://github.com/morpho-org/morpho-seatbelt/pull/53) to make sure those assets are safe to be listed. As the Optimizer is in ETH emode, the same configuration as for rETH or cbETH recently listed should be applied.

## Specification

The proposal can be translated into the following steps to be batched on the `MorphoAdmin` for sDAI:

1. `createMarket(sDAI, reserveFactor = 0, p2pIndexCursor = 0)`
2. `setAssetIsCollateralOnPool(sDAI, true)`
3. `setAssetIsCollateral(sDAI, true)`
4. `setIsSupplyPaused(sDAI, true)`
5. `setIsWithdrawPaused(sDAI, true)`
6. `setIsBorrowPaused(sDAI, true)`
7. `setIsRepayPaused(sDAI, true)`
8. `setIsLiquidateBorrowPaused(sDAI, true)`
9. `setIsP2PDisabled(sDAI, true)`

And for USDT:

1. `createMarket(USDT, reserveFactor = 0, p2pIndexCursor = 0)`
2. `setAssetIsCollateralOnPool(USDT, true)`
3. `setAssetIsCollateral(USDT, true)`
4. `setIsSupplyPaused(USDT, true)`
5. `setIsWithdrawPaused(USDT, true)`
6. `setIsBorrowPaused(USDT, true)`
7. `setIsRepayPaused(USDT, true)`
8. `setIsLiquidateBorrowPaused(USDT, true)`
9. `setIsP2PDisabled(USDT, true)`
