Create NFT Smart Contract

NFT (Non-Fungible Tokens) are currently trending hot. NFTs are used to represent ownership of any unique asset, like a deed for an item in either the digital or physical realm. The function of an NFT is based on underlying smart contracts. A smart contract is programming that exists within the blockchain.

The biggest use for NFTs today is for digital content creators. When an artist sells their content like (music, videos, GIFs, etc through NFTs, and the new owner of the content resells it, the original creator can receive a royalty. Some other use cases of NFTs could be:

  • gaming items.

  • domain names.

  • physical items, such as you could buy a car using ETH and receive the deed as an NFT in return.

  • investments and collateral such as NFT-backed loans.

This project demonstrates a basic NFT contract. It comes with a sample contract, a test for that contract, a sample script that deploys that contract, and an example of a task implementation, which simply lists the available accounts. We used the standard OpenZeppelin ERC721 contracts, the gold standard of smart contracts. 

In order to run this application you need to have a Metamask account, the minimum amount of ether required for making a transaction, a few Dependencies installed like OpenZeppelin library, Hardhat, and Alchemy. Also, you’ll need a Pinata account and an IPS server for uploading files.

Technology Stack

Following were the technical requirements for this project:

  1. React library.

  2. Programming languages - solidity, javascript.

  3. (Ethereum Development Environment) Hard Hat - It is a local-Ethereum network. We used it for compiling, debugging, and deploying contracts.

  4. (Blockchain API) Alchemy -  We used services of Alchemy like API so that it doesn't run in our system. We directly connected it to a blockchain.

  5. IPFS - for uploading files.

  6. Pinata - We used it for uploading the image to the IPFS server.

  7. (Testnet) Rinkeby - For deploying the contract.

  8. Dependencies - OpenZeppelin library.

  9. Wallet - Metamask.

Our Contribution

Initially, we created a smart contract in Solidity - MyNFT.sol and used OpenZeppelin ERC721 which is mainly used for arts and painting work. After a successful contract, we installed web3 to connect our project to Metamask.

Hardhat.config.js - Connects contract to Testnet in Metamask

Here, it is connected to Rinkeby.

We used Hardhat for compiling the contract and deploying it to Metamask.

MyNFT.sol compiledWe used the mintNFT() method of ERC721 for creating the NFT. For testing the contract, we used Hardhat and after getting the deployed address, we tested it by putting it to (rinkeby.etherscan.io).

For deploying it live, we connected Metamask with our project and we could’ve deployed it to any Testnet or Mainnet. In this case, we deployed it to the Rinkeby Testnet using Hardhat.
