Web3 App: What It Is and How to Create Your Own Application

Web3 applications are decentralized applications (dApps) built on blockchain technology. They offer greater privacy, data security, and the elimination of centralized intermediaries. While Web2 apps are based on centralized servers and managed by companies, Web3 apps operate on distributed networks and often utilize smart contracts to automate processes.

Each type of these services focuses on aspects of the digital experience: privacy, decentralization, and data control. Today, five main categories of Web3 applications can be highlighted.

Web3 Browsers

Web3 browsers differ from traditional ones by protecting user privacy and integrating blockchain functions. Users can safely browse web pages and interact directly with decentralized applications via built-in crypto wallets. Additionally, users earn rewards — tokens — for viewing advertisements.

Decentralized Data Storage

Decentralized storage systems make data more accessible and secure. Information is distributed across nodes worldwide, eliminating single points of failure and reducing the risk of data loss.
Other features include censorship resistance and cost optimization for storage.

Decentralized Exchanges (DEX)

Decentralized exchanges allow users to trade cryptocurrencies directly, without entrusting their funds to centralized organizations. Trades are executed using smart contracts, ensuring security and automation.

DEXs operate without intermediaries or central control, guaranteeing transaction privacy. Liquidity pools support trading on these platforms. For example, on Uniswap and SushiSwap, users can trade popular cryptocurrencies like Bitcoin without needing to trust their assets to a centralized exchange.

Metaverse

Metaverses provide platforms for creating, interacting with, and monetizing digital content. These spaces often integrate NFT technologies.

Users can create unique content and virtual worlds, integrate gaming ecosystems and tokens, and explore opportunities for earning and investing.

Decentralized Autonomous Organizations (DAO)

DAOs are transforming how communities and organizations are managed by eliminating the need for central administrators. Decisions are made collectively through smart contracts and community voting.

DAOs like BitDAO and Worldcoin allow participants to be involved in decision-making and project governance via tokenized voting.

Step One — Planning and Designing a Web3 Application. Start with a clear and meaningful idea that solves a problem for the target audience (TA). Sub-steps:

1. Choose a blockchain that matches the app's requirements. For example, Ethereum for smart contracts, Polygon for scalability.
2. Define which decentralized applications your solution will interact with.
3. Identify the Minimum Viable Product (MVP) with key features to bring value to users.
4. Select tools for blockchain development and a user-friendly interface (e.g., Solidity, React, Web3.js).
5. Deeply research audience needs to create a project that will be in demand.
6. Find experts experienced in both blockchain development and designing user-friendly interfaces.

Step Two — Attract an Audience. Start marketing before launching the application to build interest and gather feedback:

1. Create a document explaining the product's value, technical aspects, and potential.
2. Launch a simple website with a waiting list form to measure audience interest.
3. Start a blog and engage with potential users.

Step Three — Prototyping. Focus on user experience (UX) and interface (UI):

1. Design the main screens of the application or plugin to visualize its functionality.
2. Test the design with the audience.
3. Incorporate user feedback and refine the UX/UI before full development.

Step Four — Coding. Develop the various components of the application:

• Smart Contracts: Write and test them on your chosen blockchain.
• Frontend: Develop the user interface using Web3 frameworks like React or Vue.js.

Step Five — Testing the Application. Ensure it runs stably:

• Test smart contracts on test networks to verify their security and functionality.
• Check the interface, including the mobile version, for errors and bugs.

Step Six — Security Audit. Conduct an in-depth audit of smart contracts to identify and fix vulnerabilities.

Step Seven. Deploy smart contracts on the chosen blockchain and set up cloud infrastructure for the app's backend if necessary.

At the eighth stage, ensure stable operation and improve the application — monitor errors and fix them quickly; educate users on how to effectively use the application.

The final stage — plan major updates. Develop the application to stay relevant:

1. Collect user feedback to enhance functionality.
2. Implement new features and technologies as they emerge.

Web3 is already shaping the future of the internet, and these products are shining examples.

ChainGPT

Magic Square

Category: App Hub

Magic Square is a platform that brings together the best Web3 applications, games, and educational resources. Users can easily discover new products, participate in promotions, and earn rewards for their activity.

MoonPay

Category: Payment Solutions

MoonPay is a bridge between the traditional financial system and the crypto economy. The platform allows users to buy cryptocurrency with fiat money and exchange crypto for fiat. MoonPay supports popular payment methods, including bank transfers, credit cards, and Apple Pay.

Sleepagotchi

Category: Gamified Health App

Sleepagotchi is an app that turns sleep tracking into a game. Users earn rewards in the form of NFTs and crypto tokens for maintaining a healthy sleep schedule. The better a user's sleep, the greater the rewards.

One of the key trends in the field is the growth of the metaverse. It is expected that in the coming years, blockchain, smart contracts, and AR/VR will contribute to creating more interactive and decentralized virtual worlds, offering users new opportunities for interaction and commerce.

Another prediction is the emergence of a new economic structure. Blockchain is advancing DeFi, providing an alternative to traditional financial systems. Experts believe that collaboration between Web3 and traditional financial institutions will deepen. As a result, a more inclusive and accessible economic environment will emerge.

Web3 games are becoming increasingly popular. In the future, they are likely to offer higher-quality gameplay by combining traditional game mechanics with the advantages of decentralization. This will attract a broader audience and create new monetization models.
With the growing number of decentralized applications (dApps), the need for user privacy and security is increasing. It is expected that new technologies, such as zero-knowledge proofs and homomorphic encryption, will emerge in the future. These will allow users to maintain control over their data and ensure safe interactions on the network.

Artificial intelligence will also play a significant role in Web3's development: improving user experience and optimizing the operation of decentralized applications. AI will be used for content personalization, increasing operational efficiency, and enabling more intelligent interactions between users and platforms.

Web3 applications are opening new horizons for developers and users. Creating your own dApp is not only an opportunity to master cutting-edge technologies but also to contribute to the internet of the future.
