Copy of SNIP-20 reference implementation.

Contract for buying FOOD tokens.

Contract for instancing and feeding pet.

Some of us still remember the times back when we had our first digital pets - Tamagochi. As kids it was very challenging to keep your pet fed, clean and happy.

Fast forward 20 years. Lets implement a basic Tamagochi logic.

• Create a SNIP-20 token contract - called FOOD.

• Create a CosmWasm Market contract that gives the ability to the user to purchase SNIP-20 tokens to feed to their Pet.

• Create a CosmWasm Pet contract which implements a digital pet (Tamagochi like) interface, allowing one to feed the creature with SNIP-20/21/22/23 tokens.

• FOOD tokens can only be minted by the Market contract.
• FOOD tokens can be purchased only with the native SCRT token in ratio SCRT/FOOD - 1:100.
• Feeding the Pet (sending the Pet contract a FOOD token) should result in burning FOOD tokens.
• Pet should implement a countdown clock, which gets pushed 4 hours ahead every time the pet gets fed.
• If you miss feeding the Pet for more than 4 hours then the Pet will starve.
• If a Pet starves to death then it cannot be fed any longer so FOOD tokens shall be returned to the sender rather then burned.
