NFT Drop Contract

NFT Drop Contract


Write a contract which allows users to mint NFTs up to a count specified by the creator (e.g., 10,000) for a price specified by the creator (e.g., 200 IST). Users mint NFT IDs in first-come-first-served manner until the full count has completed.

The contract must allow the contract creator to specify:

The total count of NFTs in the series to be minted

The price per NFT

The start time (or block) of the offering, before which minting cannot occur

Optionally for the creator, a list of whitelisted addresses allowed to mint, with a limit on total number minted per address


Note: Additional context around NFT drops provided here. Not all functionality described below is necessary for this specific bounty.

NFT “drops” have been popularized on Ethereum and other chains. In these drops, an NFT creator will offer a series of NFTs that are tied to their theme, but have differing properties - with the prevalence and desirability of specific properties leading to differing rarities and values for individual NFTs in the series.

For example, all Bored Ape Yacht Club (BAYC) NFTs have a value for the “hat” property, but only 65 have the “Trippy Captain’s Hat,” making apes with Trippy Captain’s Hat rarer and more valuable than average BAYCs - currently the lowest offer for a Trippy Hat BAYC is over twice the ‘floor’ BAYC. Actual properties for the specific NFTs minted are typically only updated after the full minting is complete (not required functionality for this bounty).

At the time of the launch, users will interact with the contract (either through the creator’s dedicated UI or directly in some other manner) to mint one or multiple NFTs at the specified price.
