Decentralized applications, or dApps, have gained significant attention in the world of blockchain and cryptocurrency. These applications operate on decentralized networks, providing transparency, security, and autonomy.

Developing dApps can be a rewarding venture, but it’s essential to navigate the development process carefully to avoid unnecessary costs. In this guide, we’ll explore dos and don’ts, as well as the pros and cons, as we show you how to build a dApp from scratch.

Decentralized Applications (dApps): A Brief Survey

With the rise in blockchain technology, there has been higher usage of decentralized applications in recent years. One can easily deduce that decentralized applications (dApps) are the future of digital markets. The design and development of these applications are unique, such that they are easily able to satisfy the privacy and decentralization requirements of modern consumers.

Today, millions of people use apps regularly, and these apps have astoundingly expanded in the last five years.

One of the major features of these apps is that they do not rely on a centralized server. Apart from that, a dApp also does not rely on back-end hardware either to provide services. This unique characteristic of dApps makes them a secure option for consumers as compared to other cloud-based or even offline applications. Furthermore, generally, dApp transactions are also free of tampering.

The following are some of the major characteristics of dApps that you need to be aware of:

• They are based on blockchain systems.
• There are no censorship or outages concerning dApps.
• You will receive top-level privacy by using dApps.
• Transactions on dApps are also possible with the help of smart cards.
• You can also make use of the functionality of dApps by exchanging native tokens.

Another great advantage of dApps is that you will be able to create Web3 technology. However, some aspects of dApps make them expensive to maintain. Furthermore, in many cases, users also complained about poor UX experience in certain use cases of dApps. This is because, many times, those use cases connect to third-party wallets to gain access to the functionality of dApps.

The Basics Of Developing Dapps

Unlike traditional applications, apps run on blockchain networks, utilizing smart contracts to execute code autonomously. They operate on decentralized networks, often on platforms like Ethereum, Binance Smart Chain, or Polkadot. If you want to create a dApp on Ethereum or a similar network, you must build an app that can handle smart contracts and user interfaces and integrate with blockchain protocols.

Let’s take a look at how to develop apps!

Practical Steps When You Create A Decentralized Application With Blockchain 

Firstly, start with a comprehensive plan that outlines your app’s purpose, features, and target audience. A well-thought-out plan helps in avoiding unnecessary revisions and additional costs during development.

Leverage open-source tools and frameworks for dApp development. Platforms like Truffle, Hardhat, and OpenZeppelin offer pre-built components and libraries that can significantly reduce development time and costs.

Then, prioritize smart contract security. Conduct thorough audits to identify vulnerabilities and ensure the safety of funds and data. Investing in security at the early stages can save significant costs associated with potential breaches later.

Plan for scalability from the start. Choose blockchain platforms that offer scalability solutions or consider layer 2 solutions to accommodate future growth without incurring extensive development costs.

Engage with the blockchain community. Platforms like Ethereum have active communities where developers share knowledge, resources, and best practices. Utilize forums, social media, and developer communities to seek advice and solutions.

Don’Ts: Pitfalls To Avoid When You Create A Decentralized App 

Don’t overlook best practices when writing smart contracts. Ignoring security measures can lead to vulnerabilities, potentially resulting in costly attacks or exploits.

Don’t resist the temptation to add unnecessary features. While additional functionalities may seem appealing, they can significantly increase development time and costs without necessarily adding value to the user experience.

Don’t disregard gas costs associated with transactions on blockchain networks. Optimize smart contracts and transactions to minimize gas fees, especially when deploying and executing code on platforms like Ethereum.

Don’t underestimate the importance of a user-friendly interface. A poor user experience can lead to low adoption rates and costly updates to address usability issues.

Don’t select a blockchain platform without considering its features, community support, and associated costs. Evaluate different blockchains based on your app’s requirements to avoid potential migration costs later afterward.

How Much Does It Cost To Develop A Decentralized Application (Dapp)?

Once you have developed a dApp, it is also important for you to calculate its cost. The following are some of the major factors that you must consider while determining the cost of dApps:

1. The Dimensions Of The dApp

A simple dApp with basic features for a small company can cost between $2,500 and $25,000. However, if you are developing a dApp for a medium-sized company, it can cost between $25,000 to $200,000. On the other hand, for large companies, the cost reaches as much as $450,000.

2. Industry Specialization

This part includes the domain or industry in which your company specializes since it greatly impacts the quote. For example, creating a real estate dApp is very different from creating a dApp for a healthcare company. Furthermore, you must also be willing to pay more for newer and cutting-edge crypto initiatives. For instance, the cost of a blockchain-based social media network can be almost $100K, while the cost of a financial dApp starts from $50K.

3. Complexity Of The dApp

Some of the primary factors of a dApp include its complexity and number of features. Here are some factors you must consider related to the complexity of the dApp:

• The decentralized application’s consensus mechanism.
• Platform for building the app.
• The combination of blockchain programming languages.
• Requirements of UX/UI and API integration.
• Implementation of security protocols and authentication procedures.

Pros Of Building A Dapp Without Extra Costs

There are perks if you can build a dApp without extra costs:

Cost Efficiency: Developing a dApp without incurring unnecessary costs ensures that resources are utilized efficiently, maximizing the return on investment.

Community Support: Engaging with open-source tools and the blockchain community provides access to valuable resources, knowledge, and support, contributing to the success of the dApp.

Security Focus: Prioritizing smart contract audits and security measures from the outset reduces the likelihood of costly security breaches, safeguarding user funds and data.

Scalability Planning: Planning for scalability at the beginning helps the dApp handle increased user traffic without requiring extensive modifications, saving time and resources.

Cons Of Building A Dapp Without Extra Costs

There’s always a trade-off when you cut costs.

Firstly, this includes limited features. Strict cost considerations may limit the inclusion of certain features, potentially impacting the dApp’s competitiveness in the market.

Plus, cost-effective development may take longer due to reliance on open-source tools and community support, which might not offer the same speed as dedicated, proprietary solutions.

And, of course, prioritizing cost efficiency over user experience may result in usability challenges, potentially affecting user adoption and satisfaction.

Conclusion

Developing dApps can be a minefield of do’s and don’ts, as well as other considerations and trade-offs… each with its pros and cons. Plan carefully, with the right team by your side, and you can succeed.
