Title: [ARFC] TUSD Offboarding Plan Part II Author: Marc Zeller @marczeller - Aave Chan Initiative
Date: 2023-09-17

Summary

This ARFC proposes the continuation of the TUSD offboarding plan from Aave V2 by adjusting its risk parameters, mirroring the approach taken in the “[ARFC] BUSD Offboarding Plan Part III”.

Motivation

This proposal is a continuation of stablecoins offboarding of the Aave V2 market. TUSD is proposed to adopt the “final stage” offboarding parameters to incentivize repayment and withdrawal of liquidity in Aave V2 Pool

aBUSD will be withdrawn and converted to BUSD.

This ARFC also aims to authorize the ACI to publish regularly “withdraw aToken” mechanical AIPs that have low governance value. Part of the success of these offboarding plans relies on maintaining the available liquidity low, adding pressure on borrowers, and incentivizing repayment or, if there’s a lack of reaction, accelerating HF decay to create liquidations.

We believe that once the governance approves the offboarding plans and once an asset reaches the “final” stage of interestStrategy curve, there’s little to no governance value in going through the snapshot phase each time. A direct-to-AIP approach seems sufficient.

Specification

Risk Parameters Adjustment

The risk parameters for TUSD on Aave V2 will be adjusted as follows:

Parameter	Previous Value	New Value

Liquidation Bonus	10%	10%
Reserve Factor	95%	99.9%
