Meows(DAO) Genesis Collection

Introducing the Meows(DAO)'s Genesis NFT collection. These hand-drawn illustrations and characters are brought to life by graphic designer and artist Natalia Pankina (@natashapankina5) with a little help from generative software called Layer-cake (contributed by @atsignhandle and @gibbinator). The NFT collection, based around Natasha's illustrated character Mr. Whiskers, Inventor of the consensus mechanism Proof of Meow\u2122 and leader of the CompuGlobalHyperMega (DAO) - and his Progeny. The Progeny NFT Collection are a total population of ten thousand (10,000) adorable kitty cat image assets, each Progeny is stylized by a unique set of attributes, outfits for example range from natural with nipples to t-shirt, to formal button down shirts, including tie and a blazer. The Progeny NFT Collection makes use of additional accessories including glasses, hats, and scarves. Other attributes include background, fur, ears, brows, eyes, nose, head ware, glasses, shirt patterns and more. No two kitty cat Progeny are identical, from millions of possibilities reduced to the ten thousand hand tuned pieces with a handful of compositions including Progeny's WallStreetBets' diamond hands and the Sets. A very small number of NFTs are composed of a wide background (10417 pixels) divided into five (5) panels - thus when placed lengthwise, a composite background emerges as a single artwork, the Sets. Keen collectors will no doubt seek out joining these pieces in composing collections. The Genesis Collection includes three Sets the Alps, Space, and the Ocean. opensea.store-front.json

ERC-721 or Ethereum NFT Generative Collection

After Layer-cake, our generative image composite stack, produces over ten thousand (10,000) adorable kitty cat images, accompanying metadata files, what now? This contract a fully compliant ERC-721 token, contains the necessary additional functions for the following:

• Provenance Hash, hash of the hashes of all images, provable that the generation of the collection was the result of a single event.
• Implements a baseURI (an IPFS wrapped folder houses all the NFT metadata) where the token_id is concatenated with the baseURI to form the URI.
• Sale activation - positions the minting index so that the start position is unknown.
• Team allocation, claimable kittyCats for the team
• adoptKittyCat function whose arguments are kittyPrice * kittyCount, kittyCount

Using the BaseURI, enumerating over the JSON, any user can verify the properties of each character, its hash, and the aggregate, in order hash of the entire collection - leaving no room for feeling like a cat toy.

Opensea

The Opensea is a decentralized marketplace for the Ethereum ecosystem. It is a place where anyone can sell and buy digital assets. This contract includes a specific function used by the marketplace in order to populate a storefront. The function returns a JSON file that contains the storefront metadata.

Build

git clone https://github.com/atsignhandle/meowdao-erc721-contract
yarn
yarn run build 
yarn run compile 
yarn run test
npx hardhat run --network rinkeby ./scripts/deploy.ts 

The deployment should return an address, for example, here is what I received.

0x2D158DfF69097af8941E6a06E634B0F0A8c836Cf

Compare the deployment constructor arguments, which I referenced from config/index.ts and either use the arguments.js or pass into the following function verbatim.The following will verify the contract, in effect, publish the source code on Etherscan.
