Technical Analysis

The proposal was verified to update sUSD's LTV on Optimism to 0 to prevent further borrowing against it. In addition, the stablecoin emode was also adjusted to effectively prevent further borrowing (LTV 0.01%) and small reduction in LT to 87%. No other changes were made in this proposal for any other assets or on any other chains.

The proposal is consistent with the description on both Snapshot and the governance forum.
