The public opens its eyes a little and starts to see all the benefits of blockchain and other innovative technologies. For example, in 2022, about 1.13 million unique wallets interacted with gaming dApps, which is 60% more than in 2021. If you want to build your own dApp with Web3, you’re on the right track. We at ProCoders are ready to enrich your knowledge. How to approach the development? How much will it cost? How to invest properly? This guide will answer all of your questions. Code included! Key takeaways: Web3 dApps are applications based on blockchain. They have no central authority or control, integrate crypto easily, and are open-source. The challenges connected to Web3 dApp development are the security and scalability of the approach, as well as the search for engineers with fair prices. Typically, the architecture of such applications consists of a smart contract, a front end section, and a wallet platform for transactions. The tech stack includes Solidity, JavaScript, Web.js, and other useful languages and frameworks. To develop a Web3 dApp, you need to make 3 big steps: creating a smart contract, connecting it to the front end part, and writing the features of the app. We cover these steps in detail in this guide. To invest properly into Web3, you could develop your own dApps or invest into other profitable projects with potential. Find more ways in the guide. Decentralized Applications Using Web3: Basic Definitions So, what is Web 3 technology? What are dApps? Web3 decentralized applications’ purposes may be the same as of regular Web2 apps, but these are more innovative and democratic as they are: Open-source – heavy support, encourages engineering and improvements. Crypto-integrated – you can easily use cryptocurrency in your dApps. Decentralized – there’s no central authority, which means no censorship and process transparency. The main thing to remember here is that dApps reside on blockchain. When you create your own dApp using Web3, keep in mind that you’ll need a smart contract as a basis for it. Ethereum smart contracts using the Solidity programming language will work perfectly. For example, if you build a Web3 marketplace, the contract will automatically transfer the ownership rights to the buyer immediately after the purchase. This tech is responsible for the execution of the key processes of your app. When you read the general information about creating dApp using Web3, it may sound too good to be true. Which we at ProCoders find correct, that’s why we’ve created a list of challenges you may face when opting for Web3 technologies and decentralization. Honest communication is one of our superpowers, so we’re always open to discussing not just the roses but the thorns as well. Possible Challenges You May Face When Making Decentralized Applications Using Web3 Here are some of the most common challenges businesses and developers may encounter when building a decentralized application using Web 3.0 tech. Security Dependence on third-party tech, potential hacker attacks, and data manipulation can all undermine the security of a Web3 application. These are pre-existing risks all organizations take when entering the sector. Scalability Scalability is still a challenge for Web3 technologies, as it’s not possible at the moment to balance security, scale, and maintain decentralization. That’s why many projects compromise the latter to maintain scalability and offer premium security, which basically brings us back to centralization. Lack of developers and high rates As the industry is quite new compared to Web2, you have to really look for skilled professionals with fair rates. Gladly, there are lots of people with proper expertise. We know it better than anyone as many Web3 developers work for ProCoders and put all their effort into overcoming the previous challenges. But if you want to find the staff yourself, prepare for some high rates due to the lack of competition, especially among senior engineers. Now, how about learning a little bit about more technical details? When you try to understand make your own decentralized application with Web3, Inspired to Reshape Your Industry with Crypto? Let’s Craft Your dApp Now! Get Started! Let’s get started Typical Architecture of a Simple Web3 DApp: What to Consider for Future Scaling An important part of the answer to the “How to create a Web3 dApp?” question is the architecture of the future project. Basically, a dApp consists of: A smart contract – acts as the back end of the app. This is where you apply the business logic of your application. A wallet – takes care of the transactions necessary to operate the app, join its community, etc. Front end – user interface that receives requests and transfers them to the back end to execute. To combine all of these, you needed the JSON-RPC API by Ethereum before. Now, you can use Web3.js for this. It translates JavaScript requests into JSON-RPC. Tech Stack You Need to Build a Decentralized Application with Web3 Before we get into details on how to create a DeFi app or any other decentralized project, we have to mention the tech must-haves that will lead you to success. You’ll need knowledge of Solidity to write smart contracts for the app. For the client-side app, you’re going to use HTML, CSS, and JavaScript (frameworks like React.js work great for dApps). Some other things you’ll require: Personal blockchain for app development (such as Ganache) Node.js for development environment configuration A Solidity framework like Truffle to make it easier to create smart contracts MetaMask Ethereum Wallet to turn a simple browser like Chrome into a blockchain one. Web3.js to translate JavaScript requests to JSON-RPC. Keep in mind that the final tech stack may be different, depending on your requirements and the needs of the project.

Prev Next And now you officially have enough knowledge to finally find out how to make a dApp with Web3! Steps to Make Decentralized Applications with Web3 So, how to make a decentralized app using Web3? Here, we provide clear steps and code samples with easy explanations. Something here may sound complicated, but remember that ProCoders’ specialists are always there for you, ready to take up your project. OK, let’s dive into the steps of how to build a decentralized app. Step 1. Create a smart contract and deploy it If you already have Truffle installed, which you should, start by initializing the space you’ll be coding in by writing: mkdir greeting cd greeting truffle init If not, write npm install -g truffle. The next step is to open your code editor and add the port and IP of your Ethereum network. Then, install a Solidity compiler by writing the following: npm install -g solc// check the installed version solc --version Next, we create the greeting contract with: truffle create contract Greeting One of the final steps here is to add a migration file such as 2_deploy_greeting.js: const Greeting = artifacts.require("Greeting");module.exports = function (deployer) { deployer.deploy(Greeting); }; To deploy, type: truffle compile truffle migrate Step 2. Join the front end and back end The next big step in our “How to create a web3 dApp?” guide is setting up the front end of the app and joining it with the contract we have already deployed. For that, you need to create a Client folder, adding two files: index.html package.json For that, input: mkdir client cd client npm init -y touch index.html The next part of the mission is dependencies installation: npm i web3 --save npm i lite-server --save-dev //for running a development server Then, we work with the scripts utils.js and index.js. Make sure to create a new src folder for them and add them to the file with HTML code: <script type="text/javascript" src="node_modules/web3/dist/web3.min.js"></script><script type="text/javascript" src="src/utils.js"></script><script type="text/javascript" src="src/index.js"></script> Next, we optimize the MetaMask provider to make sure we’ll get all the benefits of a Web3 dApp we code now. You can use these docs to get all the needed knowledge on the provider and its functions. Here, we need to use window.ethereum to communicate with the users and ask if they are OK with the app accessing their accounts. To achieve that, we have to create an instance of our contract. For that, we need its address and ABI. All that and more you can find in the Greeting.json file. So, you can just copy the file and paste it into Contracts under the Clients folder. To make sure the extension is available to you, don’t forget to install jQuery by inputting the following: npm i jquery Next, the ID of the network MetaMask uses. For that, use web3.eth.net.getId(). This data allows us to get the smart contract’s address from the Greeting.json file we talked about earlier, creating an instance. Step 3. Write the methods of the contract The final step to make your own dApp with Web3 is writing in the methods of your contract: For read-only features, write myContract.methods.myMethod([arguments]).call() For modification features, input myContract.methods.myMethod([arguments]).send() This is a brief guide, but you can find the whole code here to help yourself out. Coding a dApp using Web3 can be a difficult task.
