CatCoin Cash (CATCOIN) is a digital currency created as a community-driven meme coin, aimed at catering to the online "cat" community. It functions as a peer-to-peer (P2P) cryptocurrency with decentralised transaction processing, leveraging blockchain technology to facilitate fast and low-cost payments. CATCOIN has also gained popularity as part of the meme cryptocurrency movement.

CatCoin Cash serves as a medium for online transactions and is focused on providing fast, secure, and low-cost payments. The coin can be used to make purchases online, transfer funds, and exchange for other cryptocurrencies. With the aim of increasing adoption, CATCOIN has ambitions to support charitable causes for cats and integrate further community-driven use cases.

CatCoin Cash was created under the pseudonym "Miaoshi Nekomoto" as a tribute to the broader cat-lover community. The project has developed with a community-driven ethos, and there are plans to implement further decentralised governance through a DAO (Decentralised Autonomous Organisation)​.
