Bounty: Create ERC721 AI PFP/NFT

[kamescg]

Create an ERC721 AI PFP/NFT using the Solbase smart contract library.

Required Functionality:

• Ownable
• Minting controlled by the Access Control NFT - Bounty: Create ERC721 Access Control NFT #2
• Unique Image for each NFTs (hosted on IPFS or Arweave)
• Token owner can update image with new image URI at any point.

The TurboETH Bank template demonstrates how to inherit the Solbase ERC721 and Owned smart contracts.

How It Could Work

The smart contract could be designed in a couple of different ways. Below is my recommendation, but anyone is welcome to recommend a better alternative.

Minting

The ERC721 AI PFP/NFT smart contract will be initialized with the Access Control NFT smart contract address during deployment.

The acNFT.tokenId will be used to map to an isMinted boolean mapping in the pfpNFT smart contract storage.

IF the tokenId hasn't been used, and is owned by the caller, allow a new NFT to be minted.

IF the tokenId has been used or is not owned by the caller, do not allow an NFT to be minted.

Upload PFP

When the user is minting/updating the pfpNFT they should be able to pass an image URI in the function arguments.

function mint(address to, string imageURI) external returns (uint256) {
  ....
}

function update(string imageURI) external {
  ....
}

💰 Bounty Reward

The bounty reward is undetermined. Comments and feedback are welcome.
