**Summary**

This proposal unregisters an old contract address that is no longer used in USD3. These types of proposals can happen after a collateral basket change or a major protocol upgrade. In the case of USD3, there was a recent collateral basket change proposal that was executed.

Asset to be unregistered:

saEthPyUSD: 0x58a41c87f8C65cf21f961b570540b176e408Cf2E

**Abstract**

The proposed proposal, if enacted, would unregister the Aave pyUSD(saEthPyUSD) address that is no longer being used.

**Problem Statement**

USD3 just completed a collateral basket change update, and there is a contract address that is no longer being used but still tied to USD3.

**Rationale**

By removing an old unused contract address, this improves the gas efficiency of USD3.

**Risks**

There are no associated risks by removing the unused contract address.
