How To Build A Web3 App That Mints Unlimited NFTs: Web 3 and NFTs, these ideas have been at the forefront of the digital revolution in recent years. They are revolutionising how we connect with the internet and our surroundings. Web3, or the third generation of the internet, is distinguished by its usage of blockchain technology and decentralised structure. NFTs, are distinctive digital assets that are maintained on a blockchain and can be traded just like real-world goods.
Day by day Web3 and NFTs provide new opportunities for creators to monetise their digital work. Stories and news are being circulating for the last few years of creators making life-changing money through minting and selling their NFTs. Creating an app or website that can mint NFTs for you can help you increase your chances of earning solid revenue. In this article, we will explore how to build a web3 app that mints unlimited NFTs.
What Is Web3 And How Does It Work
Web3 aspires to build a user-centric, decentralized, and trustless web. It is run on blockchain technology, making it possible to have a transparent safe system without depending on a centralized authority. Web3 has many big projects like the idea of a metaverse, a virtual environment where users can communicate with one another in real-time digitally.
One can buy and keep cryptocurrencies like Bitcoin or Ethereum to invest in Web3 or they can invest in Web3 businesses that are creating applications based on blockchain technology. Decentralized applications and services, such as NFT marketplaces and DeFi platforms, are the main emphasis of Web3 businesses.
Is Web3 Important: It can enable new business models and applications while also giving users more security, privacy, and control. Social media, gaming, decentralized finance and web 3 apps are just a few examples of Web3 applications. Users can learn more about the theories and tools used in Web 3.0 development by taking a Web 3.0 course. The process of releasing Web 3.0 is ongoing as developers work to expand and enhance the current Web3 infrastructure.
What is Web3 companion: Users can interact with decentralised applications more conveniently with the help of the Web3 Companion browser plugin. It makes it easier to access decentralized applications and connect to Web3 wallets.
NSTs are exclusive digital assets that cannot be copied or replaced. They can stand in for a range of digital assets, including songs, art and more. Examples of NFTs include the well-known Beeple painting that fetched $69 million and the NBA Top Shot memorabilia.
The process of producing an NFT on a blockchain platform is known as minting an NFT. In order to confirm and record the NFT on the blockchain, a fee is typically paid during the minting procedure. Depending on the platform and the desires of the artist, minting an NFT can also require establishing guidelines for ownership, royalties, and transferability.
What Are Smart Contracts
A smart contract is an electronic program that is kept on a blockchain. When certain criteria are met, the smart contract automatically implements the contract’s agreed-upon terms. Smart contracts are transparent and immutable, which means they cannot be amended or deleted once they are implemented on the blockchain.
A crowdfunding contract is an example of a smart contract on a blockchain, in which funds are automatically given to the project developer when a specified quantity is reached. Smart contracts can be used for a range of things, such as supply chain management, payment systems and so on.
Ethereum, Cardano, Polkadot, and Binance Smart Chain are among the most popular smart contract systems. Smart contracts that meet specific characteristics, such as having a clear intention to form a legal relationship and being entered into by parties with legal ability, can act as a legal bind.
How To Build A Web3 App That Mints Unlimited NFTs
1. Generate NFT Art:
You can take time to create your own masterpiece. Tools like Blender or Maya or a digital art creation tool like Adobe Photoshop, Illustrator or Figma can be helpful. Another way of doing it can draw on a piece of paper and then editing it digitally.
NFT-GENERATOR.ART is one helpful tool that can help you create NFT art faster and easily. Using Node.js you can generate hundreds of random NFT art. There are many tutorials available online which can help you with it.
2. Get Your Art On the Internet:
Once your art is ready to be uploaded. The JSON files can be too large to upload on a blockchain. Hence, you can upload it on a decentralized storage file system. IPFS (Interplanetary File System) is the perfect candidate for this. There are many ways to upload files on IPFS, Manually it can be done by following the given steps:
- Create a node on your computer by installing an IPFS client, such as IPFS Desktop or IPFS Companion.
- Go to the folder containing your files by launching your IPFS client and selecting it.
- Drag and drop your files into the IPFS client to add them to IPFS, or use the command line. To add a particular file to IPFS, for instance, use the command “ipfs add filename>“.
- You will be given a special IPFS hash that uniquely identifies your files once the files have been added. You can access your files on the IPFS network using this hash.
- You can use an IPFS gateway, such as ipfs.io or Cloudflare-ipfs.com, to access your files from another computer by utilizing the IPFS hash. Another easier way to do it is by using an app called Pinata. Pinanta has similar functionality to Dropbox and can be easily used to upload files on the internet.
3. Building A Web3 Application
- In case you haven’t already, install Node.js. It is available for download from the official website.
- For your web3 app, create a new project directory.
- Go to the project directory in a terminal window that is open.
- Run the following command in the terminal to start your project: npm init, new packages will be made as a result.
- In the project directory’s json file. By entering the following command into the terminal, you can install Hardhat and all of its dependencies: npm install –save-dev hardhat –> npx hardhat
- This will create a new hardhat.config.js file in your project directory, which you can use to configure your Hardhat project.
- Install the necessary plugins for your web3 app.
npm install –save-dev @nomiclabs/hardhat-ethers ethers @nomiclabs/hardhat-waffle ethereum-waffle chai @openzeppelin/contracts
Waffle is for automated testing, Ether is to interact with smart contracts in the browser and open zeppelin is used to get templates to quickly build industry standards smart contracts.
4. Write Your Own Smart Contract (ERC-721)
Create your Solidity smart contract code and save it in the contracts/ directory as a.sol file. There are many tutorials available online which will help you how to write your own smart contract using Solidity. Solidity is the most popular programming language to write smart contracts. Remember to implement the pay-to-mint function in your code. In case, you haven’t already learned solidity. It is advised to invest some time into learning Solidity. Not only it will help you build your own smart contracts but will also open many new earning opportunities.
Compile your Solidity code by running the following command in the terminal:
npx hardhat compile
This will compile your Solidity code and generate the contract artifacts required in the artifacts/ directory. Remember to test your code using Waffle.
5. Build Front-End Using Ether.js And React
- Install React and Ether.js dependencies in your project.
- Create a new React app using the create-react-app command.
- Import Ether.js in your React component.
- Connect to the Ethereum network using the ethers.providers. JsonRpcProvider class.
- Create a wallet using the ethers.Wallet class.
- Interact with smart contracts using the ethers.Contract class.
- Use React to render the UI for your web 3 app.
Again, going into the details of creating a front end in beyond the scope of this article. This is just a brief overview, there are many great tutorials on youtube which can help you with the task.
Deploying your app to the Ethereum Mainnet can be very costly. Also, in this phase, your app will be far more capable than a production-level app. To address this issue you can use a testnet to deploy your web3 app. One of the most poplular tools to deploy in the market is Alchemy. Alchemy is free tool that make it easy to deploy, manage, and scale Ethereum applications.
Deploy Using Alchemy:
- Create an Alchemy account: Go to the Alchemy website and create a free account. You will be able to create a project once you have signed up.
- Go into your Alchemy account and start a new project. You must give your project a name and select the desired chain and network you want to use.
- You can easily research the market to checkout which chain and network will be the best fit for your app. It is advised to follow a tutorial to get exact instructions on how to deploy your web3 app to the testnet.
- You must update your web3 app using your smart contract’s contract address and ABI. You can obtain the ABI of your smart contract using tools such as Remix or Etherscan.
- Once your web3 app has been updated, you may put it through its paces by interacting with your smart contract on the Alchemy testnet. To interface with the testnet and test your app, you can utilize tools like Metamask.
After you have deployed your app. Your App should be up and running.
Some Things to Keep In Mind While Building Smart Contract
- You must modify the smart contract to include a function that allows the contract owner to limit the number of NFTs that can be issued.
- Add a function: Include a function in the smart contract that allows the contract owner to specify the maximum number of NFTs that can be minted. This function should accept a parameter indicating the maximum number of NFTs.
- Once the function is added, the contract owner can set the maximum number of NFTs to a large number or infinity. This means that NFTs can be issued indefinitely.
Monetizing Your NFTs
- Your smart contract must include a transfer function that allows NFTs to be transferred across wallets. This function should be called with the recipient’s address and the ID of the NFT to be transferred.
- Create an account on a decentralized marketplace such as OpenSea or Rarible. This will enable you to build listings for your NFTs and accept cryptocurrency payments.
- Once you’ve created an account on the marketplace, you can start listing your NFTs.
- Once your NFTs are listed on the marketplace, users can use cryptocurrency to buy or sell them.
We discussed the fundamentals of web3 and NFTs, as well as how to build the front end of a Web3 app with React and Ether.js. We also went through how to use Alchemy to deploy the app to a testnet and how to commercialize the NFTs by adding a transfer function to the smart contract and listing them on a decentralized marketplace like OpenSea or Rarible. Going ahead, the opportunities and advancements for Web3 and NFTs are limitless. It will be interesting to see how Web3 and NFTs will affect the future as the space evolves.
