PEPE is a [deflationary](https://coinmarketcap.com/alexandria/glossary/deflation) [memecoin](https://coinmarketcap.com/alexandria/glossary/memecoin) launched on [Ethereum](https://coinmarketcap.com/currencies/ethereum/). The cryptocurrency was created as a tribute to the Pepe the Frog internet meme, created by Matt Furie, which gained popularity in the early 2000s.

The project aims to capitalize on the popularity of meme coins, like [Shiba Inu](https://coinmarketcap.com/currencies/shiba-inu/) and [Dogecoin](https://coinmarketcap.com/currencies/dogecoin/), and strives to establish itself as one of the top meme-based cryptocurrencies. PEPE appeals to the cryptocurrency community by instituting a no-tax policy, a redistributive system rewarding long-term stakers, and a burning mechanism to maintain scarcity of the PEPE coin.
