Does Sui have native USDC?

Could you please clarify whether Sui possesses native USDC? I'm interested in understanding whether Sui has its own native implementation of the USDC stablecoin, or if it relies on external sources for this functionality. Could you elaborate on Sui's relationship with USDC, if any, and explain any specific features or advantages Sui might offer in terms of integrating or utilizing USDC? Additionally, could you discuss any potential challenges or limitations Sui might face in relation to supporting native USDC? Thank you for your time and assistance in addressing these questions.
