Initial Pizza contract

[AddressXception]

Pizza.sol

Create a bare-bones example implementation of a pizza contract

Upgradeable, Ownable

probably using ERC-1155
opensea has some examples as well

Implementation Details

• should follow the example structure of the box (upgradeable V1)
• chainlink VRF is not needed for now (to reduce complexity while testing)

Pizza Metadata

should include an example json structure that:

• display and description metadata in both ERC721 and enjin format
• high res images
• low res images or gifs?
• the recipe
• the randomized parameters to feed into natron
• may be referenced from directly in github

slice Metadata

• includes the original slice rendering (or complete recipe) in its original index position
• includes an image of the slice in a format TBD by shrimp
• includes a link to he original pizza metadata in some way
• includes the index position

TokenUri

• should store the ipfs hashes in proxy storage

Slicing

• pizzas must be able to be sliced into 8 parts
• • each slice should have an order-based index starting clockwise
• • slices should be part of the same token contract as boxes
• • the first slice replaces the pizza artwork of the pizza token

Recombining

for owners of sliced parts, they should be able to recombine if a corresponding order index exists from the same or another pie (e.g. if i own slices 2-8 of pizza 1, and i own slice 1 of pizza 2, i should be able to recombine them into a franken pizza)

• when the pizza is recombined an event is fired
• a listener (off chain) executes the render pipeline by ingesting the render pipeline
• an event is posted back that the rendering is ready
• the token metadata is updated for the index 1 slice and the rest are destroyed or abandoned

Admin Functions

• purchaseTo
• • purchaseAndSliceTo - purchase a pizza and automatically slice it to a specified address
• • withdraw - withdraw funds

Acceptance criteria:

• Two pizzas with different metadata should be sliced
• slices from the two pizzas should be transferrable
• pizzas should be able to be recombined with corresponding slices from the other pizzas
