When was the last time you used a digital application? Many of us will say never. Even the most tech-savvy person can only sometimes distinguish between a decentralized application and traditional software. So what difference does it make?
With Bitcoin and other cryptocurrencies reaching new all-time highs, developing dApps — blockchain-based apps — is quickly becoming a hot topic. We’re here to help you separate the hype from the practical applications of this remarkable, albeit not entirely new, technology. Keep reading to learn how to create a dApp on Ethereum.
Step 1: Build A Smart Contract
The decentralized logic of your dApp would be housed in a smart contract go or a combination of smart contracts. According to chain consensus, what actions do you want the dApp to carry out automatically?
These automatically executing features, whether simple transactions, a chain of algorithm computations or something else, will need to be housed in smart contracts.
Because smart contracts operate on blockchains, you’ll need to choose one or more blockchains if you want to create a cross-chain dApp. Founders typically create a dApp on Ethereum, but other chains also support smart contracts.
The Ethereum network is an obvious choice because it has many users who already have crypto wallets and can onboard quickly. Users do not need to know which blockchain your dApp works on if you plan to introduce your crypto wallet.
It doesn’t matter which blockchain you use to onboard a large, diverse audience unfamiliar with blockchain technology.
Step 2: Build Front Ends
Of course, creating a decentralized app requires the development of “normal” user-facing mobile and/or web apps. By regular, we mean they should look similar to other apps we use daily.
The fact that user actions trigger some smart contract functions on a blockchain rather than connecting to a central server should have little impact on the user interface.
As a result, if you want to create an engaging user experience, start with a prototype:
- low-fidelity UI
- high-fidelity UI
- user testing
- reinforce the UI/UX based on the feedback
Consider that calling a smart contract function from a user-facing UI takes some time because transactions on a blockchain are executed after some time. It’s a good idea to include some animation on the front end to show users that their action is still in progress until it’s verified on the chain.
Step 3: Create a Centralized Back End
Suppose you’re developing Ethereum dApps that require massive data storage, want to run reports, or have any other functionality that isn’t possible with on-chain transactions. In that case, you’ll need a web solution on a private server.
An admin portal of this type will connect to smart contracts and front-end applications for customers to provide additional features to you as a business owner (to control your dApp) and users.
Step 4: Test Rigorously
You should begin testing your dApp as soon as possible during development, just as with any other app development project. Every new build must go through a rigorous testing process.
While testing front-end apps is a fairly standard procedure, smart contract testing is different in that it requires using a testnet to verify its functionality.
Otherwise, once a smart contract has been deployed to the mainnet, such as Ethereum, it can no longer be modified. Any bugs that made it to the mainnet will remain unaffected.
Step 5: Deploy And Maintain
The final step is to deploy your dApp. This process includes uploading mobile apps to the App Store and Google Play, moving your back-end portal to a live production environment, and adding a smart contract to the blockchain. DevOps efforts for deploying a decentralized app can be reduced with services like Infura.
Maintenance is more of a continuous process. Even if the smart contract remains the same as a blockchain app impervious to changes, you will still need to update things on the front end.
That’s all about how to create dApp Ethereum. Furthermore, you may need to create a back-end system that aggregates analytics and allows you to run reports and manage some aspects of the dApp. Simply put, it is a web application that is linked to the smart contract via oracles and APIs.
There are quite a few pieces to juggle. A competent app development team experienced in building dApps will assist you in sorting out all of these technical complexities. Contact SmartOSC if you need help with dApp development services.
