The CaskNFT contract was designed to provide Metacask a mechanism on minting a non-fungible token accurately representing the descriptive + administrative properties of a physical asset "whiskey cask" on the Casper Network through Metacask's NFT marketplace Dapp. Its design allows the CaskNFT contract to interact with other contracts in the marketplace ecosystem that facilitate the auction mechanics.
- the Auction contract to emulate the real-life operational procedures in administering the ownership rights, purchase, sale, transfer of ownership and funds between marketplace actors in English + Dutch style auctions.
- all while complying with regulatory requirements on identity verification standards managed by the KYC Contract.
