[ARC] Risk Parameter Recommendations for Aave V2 ETH (2022-11-22)

Proposal to Disable Borrows for Long Tail Assets

Hey all - happy to see a constructive discussion regarding the next steps. Reading through the thread, with proposals and support from @eboado, @llama, @stani, and ourselves, it seems that a consensus is forming around the following parameters changes:

Asset Status Proposed Action
$YFI Borrowing Enabled, Collateral Enabled Disable Borrowing
$CRV Borrowing Enabled, Collateral Enabled Disable Borrowing
$ZRX Collateral Enabled, Borrowing Disabled Freeze
$MANA Borrowing Enabled, Collateral Enabled Disable Borrowing
$1inch Borrowing Enabled, Collateral Enabled Disable Borrowing
$BAT Collateral Enabled, Borrowing Disabled No Change
$sUSD Borrowing Enabled, Collateral Disabled No Change
$ENJ Borrowing Enabled, Collateral Enabled Disable Borrowing
$GUSD Borrowing Enabled, Collateral Disabled No Change
$AMPL Borrowing Enabled, Collateral Disabled Freeze, RF to 99%
$RAI Borrowing Enabled, Collateral Disabled Freeze
$USDP Borrowing Enabled, Collateral Disabled No Change
$LUSD Borrowing Disabled No Change
$xSUSHI Collateral Enabled, Borrowing Disabled No Change
$DPI Collateral Enabled, Borrowing Disabled No Change
$renFIL Borrowing Enabled, Collateral Disabled Freeze, RF to 99%
$MKR Borrowing Enabled, Collateral Enabled Disable Borrowing
$ENS Borrowing Enabled, Collateral Enabled Disable Borrowing
$LINK Borrowing Enabled, Collateral Enabled Disable Borrowing
$UNI Borrowing Enabled, Collateral Enabled Disable Borrowing

Next steps

We’ll follow up shortly with a proposal. After these changes are approved, the community should discuss amendments to LT and LTV of different assets, allowing some of the above changes to be relaxed without compromising healthy user positions. We’ll be adding data regarding this soon so we can understand the associated implications of parameter reductions to user positions.

Thank you @Llamaxyz and @MatthewGraham for collaborating on this proposal.
