The MoonCatRescue project launched on the Ethereum blockchain in 2017, as a fun exploration of what’s possible with that new technology platform. The project formed a collection of colorful digital companions by guiding visitors to “rescue” them from the moon, and make them permanent residents of the blockchain. MoonCats were NFTs, before “NFT” was an established term, and their multi-year history is a great way to get introduced to the space. Articles in this publication focus on helping explain and introduce blockchain technology space in general, helping you pick a colorful MoonCat companion for yourself and have them show you the possibilities of the Web3 space, and expanding the lore around the MoonCatRescue ecosystem.
