Aave

Simple Summary

This AIP proposal presents Aave with the opportunity to onboard MAI to the Optimism v3 Liquidity Pool.

Motivation

Supporting stablecoin diversity is part of the Aave-Chan Initiative (ACI) delegate platform.

The ACI does not have any link nor is paid by QiDAO or any entity to present this AIP.

The risk parameters provided introduce MAI as a collateral asset.
