FEI Risk Parameter Updates for Ethereum Aave v2 Market

By 0x55B1...09f262

Simple Summary

In response to Tribe DAO’s proposal to enter a terminal state, this ARC proposes disabling Deposits, disabling Borrowing and route 100% of the interest paid by FEI borrowers to the Reserve Factor.

Abstract

Tribe DAO is dissolving the DAO’s assets and TRIBE governance token. As a result, FEI will become backed 1:1 with DAI and redeemable 1FEI:1DAI. With Tribe DAO transitioning into a terminal state, the FEI stablecoin will overtime be redeemed for DAI.

As FEI is redeemed for DAI, over time FEI’s circulating supply and liquidity will fall away. Without sufficient liquidity, liquidations can not be performed efficiently which creates a risk for the Ethereum Aave v2 market.

In response, this ARC proposes freezing the FEI market which will Disabling Deposits, Disabling Borrowing and increase the Reserve Factor from 20% to 100%. Users will still be able to redeem aFEI and repay debt.

Motivation

With the emergence of news that Tribe DAO intends to dissolve FEI and the Protocol Controlled Value (PCV) backing the stablecoin, there is a need to amend the FEI reserve in preparation of the risks to emerge with transition Tribe DAO to a terminal state.

The details around how Tribe DAO will transition from current state to terminal state can be found here.
