[ARFC] Generalized LT/LTV Reductions on Aave V3 Step 2 - 04/23/2024

Summary

Reduce stablecoin LTs and LTVs across all markets.

Motivation

Following a successful implementation of Phase I of our plan to reduce stablecoin LTs and LTVs, we would like to propose the next phase. Additionally, we have updated our recommended final state for all associated stablecoins, with LTVs and LTs harmonized across all chains at 75% and 78%, respectively.

Please note that given the proposal to adjust DAI and sDAI risk parameters, it has been excluded from this proposal.

Hello,

echoing our previous comment considering the relative smaller size & business potential of sDAI as collateral, we suggest to revert their risk parameters on Ethereum & Gnosis markets to levels pre-AIP 87 & in sync with current proposal with 75% LTV & 78% LT
