What chain is Nyan Heroes?

I'm curious to know, what blockchain network does the Nyan Heroes project operate on? I've been hearing a lot about it lately and I'm eager to understand the technical foundation that supports this innovative cryptocurrency or token. Is it built on Ethereum, Binance Smart Chain, Solana, or perhaps another lesser-known blockchain platform? I'm eager to gain a deeper understanding of the technology behind Nyan Heroes and how it fits into the broader cryptocurrency landscape.
