The project you are talking about is a simple Ethereum token, Pepecoin is a coin with its own Blockchain. So there are some major differences. It is still a brand new project as well which just got listed on its first tier1 Exchanges. Soon there will be an Onramp and it will be listed on another tier 1 exchange (rumors are Kraken) Coinomi just added pepecoin.org to its wallet and Exodus will soon add it as well. Inscriptions are already being done and the first markeplace is in development.
