Important Things To Know

Acclimated MoonCats

Acclimated MoonCats are MoonCats that have been wrapped in the Official Wrapper to bring full ERC-721 compatibility to the project. The original contract predated the ERC-721 standard. "Acclimation" is fully reversible, and the original MoonCat token can always be recovered. All new features and projects require MoonCats in the Official Acclimated Wrapper.

(Technically, Acclimated MoonCats are actually ERC-998 tokens, a more advanced form of ERC-721 NFTs).


The first major expansion of the MoonCat project is their unique Accessories system. Accessories are entirely on-chain collectibles for MoonCats to own and display. Anyone can create an accessory, using the Accessory Designer, specify its scarcity and price, and make it available for sale in the Accessory Boutique. Accessories stay with the MoonCat forever, but can be put on or taken off at any time.


There are a total of 25,440 MoonCats, and Ponderware is committed to never minting any additional MoonCat tokens. Of these, 96 are known as Genesis Cats which are the only cats colored Black or White (sometimes with Grey), and 25,344 are Rescue Cats, selected by users during the minting process. Originally, 256 Genesis Cats were planned for release, but the remaining 160 were permanently locked as dictated by the outcome of the Genesis Vote in March 2021.

Historical Significance

The MoonCatRescue project was a trailblazer in NFT systems and dynamics. Some of these innovations still stand-out in the space. The original website is preserved as an artifact.

Fair Distribution

MoonCatRescue used an on-chain proof-of-work mining system to allow people to "locate" and "rescue" MoonCats. Of the billions of possibilities, it was up to the community to decide which cats would be rescued, and therefore what the trait distributions would ultimately be. No profit was made from the minting of any MoonCat; rescuing a MoonCat was free, just the cost of gas, and the fees charged to adopt a Genesis MoonCat were burned.

On Chain Generation

Each MoonCat's DNA (known as their catId) is a unique on-chain value which determines all the traits of the MoonCat. This DNA can then be expanded in the image of that MoonCat.

Community Participation

The full selection of rescued MoonCats was determined by the community as they selected which specific MoonCats would be rescued.

Each MoonCat can be named exactly once by their owner. The names are stored immutably on the Ethereum Blockchain, allowing permanent user-customization of each MoonCat NFT.

In 2021, this spirit of participation and customization was expanded to include the unique MoonCat Accessory system.


More than an NFT, the MoonCat story has always been a central aspect of the project. Much of it is documented in the ChainStation logs, and on the Original Website. The Lore and Universe continue to develop, in collaboration with the community and in reference to unfolding events. The MoonCat story is far from over.

MoonCat Winter & Rediscovery

MoonCatRescue was developed and released in 2017 by a pair of Ethereum enthusiasts who wanted to explore the possibilities of the early Ethereum network. The duo were artists and developers, but struggled to market the project effectively. Though MoonCats gained a small and passionate following, interest never ballooned and by late 2018 had dwindled to almost nothing. Ponderware kept the project on life support but the functionality of the interface dwindled and bitrot set in...

Fast forward to March 12, 2021, thanks to the efforts of crypto-archeologists like 0xAllen,Adam McNFT, ETHoard, & JUSTIN, MoonCats were rediscovered. In a bout of MoonCat mania, all of the remaining MoonCats were rescued over the span of just a few hours. Though you could still mine on the original website, actually claiming cats required that you interact with the smart contract directly, which people quickly learned and taught others to do. On this day, from grass roots, the MoonCatCommunity was born!

As soon as ponderware learned of the rediscovery, the team got to work re-establishing communication with the MoonBase. Upon the return of ponderware, the question of whether to mint the remaining Genesis MoonCats rose to the forefront. Ponderware's first act in joining the community was to put the issue to a vote, setting the stage for the ongoing atmosphere of community collaboration that continues today.

The project continues to develop and community continues to grow, as the #AgeOfMoonCats continues.
