[ARFC] Onboard stcUSD to Aave V3 MegaETH
[ARFC] Onboard stcUSD to Aave V3 MegaETH
Author: Aave Labs
Date: 2026-06-19
Summary
This ARFC proposes onboarding stcUSD to the Aave V3 MegaETH instance.
This listing would initially enable users to deposit stcUSD to earn yield and borrow stable assets to earn leveraged yield on their yield-bearing asset.
Motivation
stcUSD is the staked, yield-bearing component of Cap Protocol.
Users mint stcUSD by staking cUSD, with yield generated from the underlying cUSD collateral and protocol-level yield mechanisms.
Supplying stcUSD as collateral lets holders keep earning stcUSD yield while borrowing stablecoins against their position. This adds incremental stablecoin borrow demand on the MegaETH instance, making it more attractive for stablecoin suppliers over time.
LlamaRisk has already provided the risk assessment for stcUSD.
