Is USDC only on Ethereum?

I'm curious about the availability of USDC. Is it limited to the Ethereum blockchain, or does it exist on other platforms as well? It seems like Ethereum is a popular choice for many cryptocurrencies, but I'm wondering if there's any diversity in terms of where USDC can be found. I'm interested in understanding the full scope of its accessibility and usage across different blockchains. Could you clarify this for me?
