Well, today we will see, how we can create a simple NFT using the Solidity programming language. And, we will also see, how we can deploy the NFT.
Excited? Me too :)
Before moving forward I assume you are aware of NFT, and how it works, if not, please check out my article aboutthis. Great!
To create an NFT (Non-Fungible Token) with a blockchain, you will need to use a programming language to interact with the blockchain’s API orApplication Programming Interface.The exact steps and code you need to use will depend on the specific blockchain you are using, as different blockchains have their own unique APIs. In this article, we will use Solidity as a programming language with the Ethereum blockchain!
NFT is nothing but a smart contract written in Solidity. Let's see all steps to create.
Cool, Now let us see these steps with an example!
pragma solidity ^0.8.0//we have to import openZeppelin libraryimport "https://github.com/OpenZeppelin/openzeppelin-solidity/contracts/token/ERC721/SafeERC721.sol";// Contract that represents a collectible itemcontract Collectible is SafeERC721 { // Unique identifier for the collectible uint256 public collectibleId; // Additional metadata for the collectible string public name; string public description; string public imageUrl;constructor(uint256 _collectibleId, string memory _name, string memory _description, string memory _imageUrl) public { collectibleId = _collectibleId; name = _name; description = _description; imageUrl = _imageUrl; }};
After defining our NFT contract, we will need to compile it using a Solidity compiler. It will produce a bytecode version of your contract which can be deployed to the Ethereum blockchain later.

How we can deploy it?
To deploy our NFT contract to the Ethereum blockchain, we will need to use a tool like Remix or Truffle to send a transaction to the blockchain with the bytecode for your contract. It will create a new contract on the blockchain which represents our NFT.
Once our NFT contract is deployed, w can use it to create new NFTs by calling the contract’s “mint” function and passing in the necessary data for each NFT.
let's see this also in coding.
/ we need to connect to the Ethereum blockchain (rinkebyWeb3 web3 = new Web3("https://rinkeby.infura.io/v3/YOUR-API-KEY");// then we have to load our NFT contractCollectible contract = Collectible.load(OUR_CONTRACT_ADDRESS, web3, CREDENTIALS);// finally, we can create our NFTcontract.mint(1, "Collectible #1", "This is the first collectible", "https://example.com/collectible1.png");)
Yeah, we successfully created and deployed our simple NFT using Solidity with the Ethereum blockchain.
It is just a basic example of how we can create an NFT with the Ethereum blockchain using Solidity. There are many other considerations and steps to be aware of when working with real NFTs and blockchains.
I hope you guys love reading this and got some idea about how we can create and deploy an NFT. In the coming future, I will come up with an article like this. Stay tuned!
Thanks for reading :)

Nice article! I have one piece of advice, using "pragma solidity ^0.8.0" is not safe, as it means any Solidity compiler with the version 0.x.x can compile your contract. It's better to fix it to a specific version, example "pragma solidity 0.8.20".
