What network is Pepe on?

Excuse me, could you please clarify for me which network Pepe is currently operating on? I understand that Pepe is a popular meme or character, but in the context of cryptocurrency and finance, it's not immediately clear to me which blockchain or network it's associated with. Is Pepe perhaps a token or a digital asset on a specific blockchain platform? If so, could you provide me with more information about the network and its features? I'm very interested in learning more about this. Thank you for your time.
