Recently, 100m DAI were deposited on Morpho Blue through a MetaMorpho vault managed by the Spark DAO, following a [proposal](https://forum.makerdao.com/t/introduction-and-initial-parameters-for-ddm-overcollateralized-spark-metamorpho-ethena-vault/23925?u=0xloth.morpho) on Maker.

This event prompted the submission of a [proposal](https://governance.aave.com/t/arfc-risk-parameters-for-dai-update/17211/2) on Aave’s forum to set the Loan-to-Value (LTV) to 0 for every DAI market on all Aave instances (AaveV2 and AaveV3).

Since there is low usage and to prevent any side effects on Aave Optimizers, the Morpho Association has proactively implemented the following measures:

- Paused the supply of DAI on AaveV2.

- Paused the supply of DAI and sDAI as collateral on AaveV3 Optimizers.

- Disabled DAI and sDAI as collateral from AaveV3 Optimizers.

- Disabled DAI and sDAI as collateral on AaveV3’s pool for the AaveV3 Optimizers.

These steps ensure that, should this proposal pass, Optimizers and their users will not be affected.

No user lost funds during this operation.
