Breaking NFTs into Bits: A Guide to Fractionalize NFTs Using Solidty Smart Contracts

Fractionalize your NFTs: Writing Smart Contracts in Solidity

Are you interested in the world of blockchain, digital art, and Non-Fungible Tokens (NFTs)? Have you been on the lookout for ways to capitalize on the fascinating opportunities that technology tosses your way? If you have, and if you cannot wait to make your first million in the crypto world, sit tight. Let’s delve into the fascinating world of Solidity and smart contracts geared towards fractionalizing NFTs.

A Sneak Peek Into The Realm Of NFTs

Before setting sail into the majestic terrain of smart contracts and Solidity, it’s essential to understand what NFTs are. NFTs, or Non-Fungible Tokens, are unique cryptographic tokens that represent ownership of unique items or content. They are built on blockchain networks and are different from other cryptos such as Bitcoin or Ethereum because no two NFTs are alike. They are unique and carry unique information.

The Need For Fractionalizing NFTs

You might question – Why even bother fractionalize NFTs? The fact is, many NFTs carry high value and may be unaffordable to an average investor. By fractionalizing an NFT and distributing ownership among multiple investors, we can democratize access to such high-value tokens.

An Introduction to Solidity

Solidity is an object-oriented, high-level language primarily used for implementing smart contracts. It was conceived to interact with the Ethereum Virtual Machine seamlessly. Solidity is statically typed and supports libraries, complex user-defined types, and inheritance.

Writing Smart Contract

Let’s talk business now. How does one create a smart contract that fractionalizes an NFT? The steps below outline a simple approach to this task.

Note: The code shown is illustrative and may not work in a real-world setting. Furthermore, it’s shortened for the sake of readability, and safety checks have been omitted.

pragma solidity ^0.6.0;
import "@openzeppelin/contracts/token/ERC721/ERC721.sol";

contract FractionalizeNFT is ERC721 {
    using SafeMath for uint256;

    struct Fraction {
        uint256 total;
        mapping(address => uint256) fractionOwners;
    }

    mapping(uint256 => Fraction) public fractions;

    function fractionalize(uint256 tokenId, address[] calldata owners, uint256[] calldata stakes) public {
        require(msg.sender == ownerOf(tokenId), "Only the owner can fractionalize");
        require(owners.length == stakes.length, "The owners list and stakes list lengths must be equal");

        Fraction storage fraction = fractions[tokenId];
        for (uint256 i = 0; i < owners.length; i++) {
            fraction.fractionOwners[owners[i]] = stakes[i];
            fraction.total = fraction.total.add(stakes[i]);
        }
    }

    function claim(uint256 tokenId) public {
        require(fractions[tokenId].fractionOwners[msg.sender] > 0, "No ownership stake");

        uint256 stake = fractions[tokenId].fractionOwners[msg.sender];
        fractions[tokenId].fractionOwners[msg.sender] = 0;
        fractions[tokenId].total = fractions[tokenId].total.sub(stake);

        if (fractions[tokenId].total == 0) {
            _mint(msg.sender, tokenId);
        }
    }
}

The Final Takeaway

Flexibility is one of the most seductive aspects of blockchain technology. Fractionalizing an NFT introduces an entirely new dimension of flexibility, enabling investors with smaller capacities to participate in purchasing high-cost NFTs. Moreover, it provides NFT owners with an efficient way to liquidate a part of their ownership without giving up the entire piece.

Writing a smart contract to fractionalize NFTs in Solidity is not as complicated as it may seem, provided you have the right guidance. However, take note, right behind the codes’ allure lies the need to consider and understand security, minting, claimant aspects, and much more.

To thrive in the exciting blockchain ecosystem, continue to learn and adapt. The flexibility and economic inclusivity promised by fractionalizing NFTs are incredibly promising, and mastering the art of writing such smart contracts is undoubtedly a useful skill in the decentralized world.
