Implementation of the FA2 NFT collectibles promotion auction. The promoter, who owns collectible NFT tokens can create a promotion auction contract with the set price per collectible token. Auction participant transfer money tokens to the auction amd receive collectible tokens in exchange.
Since the permissions_descriptor for FA2 contracts is represented on-chain as
a contract storage field, it is not duplicated in the contract metadata as
required by TZIP-12/TZIP-16.
A promoter who owns some collectible NFT tokens can create an instance of promotion. The promotion definition contains FA2 address of the NFT collection, FA2 fungible "money" token used to pay for collectibles and a price per collectible token.
The promotion starts when the promoter transfers one or more collectible NFT tokens to the promotion contract.
Once promotion is in progress, other participants can transfer money tokens to the promotion contract. The promotion allocates promoted tokens to the participants and keeps remaining money balances.
The promotion stops if all promotion tokens are allocated or if the promoter explicitly stopped it.
At any time when the promotion is in progress or stopped, any participant may request refund (transfer back) the remaining unspent money balance and/or to disburse already allocated collectible tokens.
If the promotion has been stopped and not all collectible tokens are allocated, the promoter should request to disburse remaining collectibles.
