Bulgari Address-bound Tokens

Polygon Address - 0xea58a24502f065a8cd53b94424d7b0e82b6e697c

Mints Limited Edition of a Digital Artwork as Address Bound Tokens (ABT, also called Non-Transferable NFTs, or Soulbound Tokens if attached to an identity). Each minted token can be given to a participant invited to a physical event. The contract:

• only allows contract owner to mint new tokens;
• mints no more than one token for the same guest;
• mints no more tokens than the amount of invited guests;
• allows to forever end minting before reaching the number of invited guests (some guests may not claim it);
• tokens aren't burnable.

Why Address Bound Tokens

The ownership of this token is (a) an eternal and public statement about the holder, is (b) a possible set of rights over the digital artwork it encapsulates, and (c) must serve no lucrative purposes. Standards such as ERC-721 or ERC-1155 are too complex for the use-case and require disabling some of their core functionalities (especially for ensuring (c)). This Smartcontract leverages ideas from the ERC-1238 standard discussion, can be improved in multiple ways, and poses itself as the first of a series of experiments.
