Technical analysis

We have verified that the payloads modify the LTV and LT of the following assets to the declared values:

• stMatic - LTV = 48%, LT = 58%

• MaticX - LTV = 50%, LT = 60%

• OP - LTV = 58%, LT = 63%

• ARB - LTV = 58%, LT = 63%

• GNO - LTV = 48%, LT = 53%

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