What chain is pyr on?

Could you please clarify which "pyr" you are referring to, as there may be multiple projects or tokens with similar names in the cryptocurrency space? However, if we assume you are asking about a specific blockchain project or token named "PYR", it's essential to note that the answer would depend on the context and the specific project you're inquiring about. In general, when asking about the blockchain or network a particular cryptocurrency or token is built on, the answer could be any of the major blockchain platforms, such as Bitcoin, Ethereum, Binance Smart Chain, Solana, Polkadot, or even a lesser-known or proprietary blockchain developed specifically for that project. Without knowing the exact project or token you're referring to, I would encourage you to check the project's official website or documentation for more information about the blockchain it's built on. Additionally, you could also search for the project on cryptocurrency forums, social media platforms, or dedicated websites that track and analyze blockchain projects.
