This RFC proposes a very large batch of ARKs for USDC Mainnet, which makes review more challenging; especially given the pending @BlockAnalitica risk assessments. I’d like to see more clarity on Clearstar (all variants), Midas Hyperithm, and Upshift before moving forward. That said, I’m generally supportive of onboarding Morpho Alpha USDC Core, Euler Frontier mAPOLLO (USDC), Midas MEV, and Midas Apollo Crypto as they bring meaningful diversification and active yield strategies to the Higher-Risk vault.
