MaticX Risk Parameter & Interest Rate Upgrade

Summary

Llama proposes upgrading the MaticX Reserve on Polygon to facilitate an expansion of the MaticX/wMATIC loop strategy.

Abstract

Utilisation of the MaticX reserve has been trending higher over time and with the introduction of deposit rewards, the SupplyCap has been reached and it now prohibites additional MaticX being deposited.

Increasing the SupplyCap enables the recursive MaticX/wMATIC strategy to grow beyond the current constraints. Enabling borrowing, with a reasonable BorrowCap and SD rewards, is expected to generate significant utilisation of the MaticX reserve.

This proposal facilitates the expansion of MaticX yield based strategies on Aave v3 Polygon by creating more favourable bootstrapping conditions. The introduction of liquidity mining rewards is expected to drive notable inflows and usage to the v3 deployment.

Motivation

Over the previous months, Llama has been working with various communities to craft favourable conditions on Aave v3 Polygon to facilitate the creation of several yield aggregation products. The below proposals details are applicable:

• Proposal to add MaticX to Aave v3 Polygon Market
• ARFC Aave v3 Polygon wMATIC Interest Rate Update
• ARFC SD Emission_Admin for Polygon v3 Liquidity Pool
• ARFC stMATIC & MaticX Emission_Admin for Polygon v3 Liquidity Pool

This proposal is a continuation of the above work.

In support of the ongoing SD rewards distribution, this proposal seeks to increase the SupplyCap, enable borrowing and introduce a BorrowCap sufficient to create a notable deposit yield.
