Minter of ERC721

[Khyati729]

Description

In Carbon Protocol v3 - When the user calls the mint function (to mint ERC1155, in project.cairo) for the first time, it should also mint an ERC721. For the moment, we don’t mind what ERC721 it is and the details about it.

User Flow

User buy with the public_buy function ⇒ call of fn mint in project.cairo ⇒ mint of a dedicated ERC721 with mint function of that ERC721.cairo ⇒ then mint of the regular erc1155.

Additional context

[ Medium Difficulty - Cairo - High Priority]

Acceptance Criteria

• [ ] Create ERC721 contract with dummy details. Only the contract project.cairo should be allowed to call mint function from that ERC721 contract.
• [ ] add the call to mint 1 NFT of that new contract when we call mint from project.cairo
• [ ] If the user already minted an NFT from that dummy ERC721 contract, don’t mint an other one and just mint ERC1155.
• [ ] Follow Contribution guidelines and ask for help if needed in the CarbonableOD Telegram: https://t.me/carbonableOD

Hello @Khyati729 ! My name is Daniel Calderon, I'm a software developer and OD contributor from Costa Rica, and this is my third ODHack, I would love to help with this issue during the current one, also I already joined the TG group. I will tackle this issue by:

• Creating a simple ERC721.cairo contract with a mint function, on this function, I will verify that the contract calling the method should be project.cairo, also I will validate that an address or user can't mint more than one ER721 token/nft.
• I will add this call to the mint function in project.cairo, the call of this function will mint an NFT only if it is the first time
