Mogies Dutch Auction Contract

A variation on the ERC-721A Non-Fungible Token Standard The following smart contract allows for the implementation of a "Dutch Auction" sale for NFTs. This standard provides basic functionality for selling NFTs and other functionalities including:

• Whitelist

• Public Sale

• Token Rebate

• Developer Mint

• Bonus Mint

Functions

auctionMint

function auctionMint(uint32 quantity, bool isUsingStars)

Function to handle the dutch auction

allowlistMint

function allowlistMint(uint32 quantity,bool isStars,bytes32[] memory _proof)

Function to support the whitelist sale

isAllowedListed

function isAllowListed(bytes32[] memory _proof, address _address)

setAllowListMerkleRoot

function setAllowListMerkleRoot(bytes32 _allowListMerkleRoot)

Function for contract owner to allow merkle tree during the whitelist sale

publicSaleMint

 function publicSaleMint(uint32 quantity, bool isStars)

isPublicSaleOn

function isPublicSaleOn() public view returns (bool)

setPublicSale

 function setPublicSale(bool _publicSale)

setAuctionEthParams

function setAuctionEthParams(
        uint256 _auctionStartEthPrice,
        uint256 _auctionEndEthPrice,
        uint256 _auctionDropPerStepEth
    )

Helper functions for setting prices right before auction. Will only be needed when large price fluctuations occur between deployment of the contract and start of auction. Will no longer be avaliable once the sale has started.

setAuctionStarsParams

    )
