Discovered living on the moon back in 2017, they were rescued by many adventurous Etherians, and brought onto the blockchain. They now coexist happily with their human Etherian friends, serving as companions and guides into the uncharted Deep Space.
MoonCats are the primary NFT collection of the MoonCatRescue project. The original contract was deployed in 2017, before "NFT" was an established term. They were rescued ("minted") and brought to ChainStation Alpha (the Ethereum mainnet blockchain), and are the key characters guiding their human owners through Deep Space (the forward-looking possibilities of blockchain/web3 technologies).
