Technology Tools that pillar our dApp Development Services

We use Geth to launch Ethereum node, transfer funds between addresses, explore block history, mine Ether and create contracts.
We test out the dApp on Blockchain Testnet before launching it on the mainnet to prevent the system from bugs and issues.

We utilize Zeppelin tools to perform the security audits on the smart contracts and manage reusable smart contracts efficiently.
Our team of dApp developers also use BlockStack to build scalable dApps that allow users to own their data. The platform enables us to write the dApps in any programming language.

Our dApp Development Company uses Truffle which offers a development environment and asset pipelines for Ethereum application development. It allows custom deployments for many public and private networks.

FAQs

What are dApps?

dApps (Decentralized applications) run on a peer-to-peer network of computers instead of a single computer. They are similar to a conventional web application in a way that its front end uses the same technology to represent the page. But the backend uses smart contracts to connect to the blockchain network instead of an API connecting to the database.

Advantages of dApps over Traditional apps

  • dApps are tamperproof and records stored in it are unalterable, protecting the application from hacking or intrusions.
  • Decentralized apps are governed through autonomy and changes made in the applications are decided through consensus of all members in the network.
  • Unlike traditional apps, decentralized applications i.e. dApps do not rely on a single server and therefore, it prevents the risk of central point of failure.

What type of dApp suits your business case?

dApps are classified into the following three types:

  • Type 1: dApps with their own blockchain, for example, Bitcoin.
  • Type 2: Using the blockchain of Type 1, these dApps are protocols with token essential for their functions, for example, Omni protocol.
  • Type 3: These dApps use Type 2 dApp’s protocol, for example, SAFE network issuing Safecoins using Omni Protocol.

What is dApp Development?

dApp Development is the process of building decentralized applications with backend code running on a decentralized peer-to-peer network. The difference between traditional and dApp Development is the way programming is done. The coding of dApp is more rigorous than traditional app development as the code of the smart contract is unchangeable once it is commenced on the mainnet.

We provide dApp development services that include decentralized exchange development, smart contracts development, dApp consulting, dApp porting and dApp upgrade services. 

What are the steps in dApp Development Process?

Here are the steps involved in the dApp Development Process:

  • Analysis and Ideation
    Firstly, you need to analyze whether your business use case needs to be built on the decentralized network or not. Once you decide that you require a dApp for your business, you need to identify the technology components required to develop a dApp. Also, define on-chain and off-chain business entities
  • Proof of Concept
    After analyzing and identifying the tech components, the next step could be developing a PoC to test the viability of the proposed solution with minimum features.
  • Visual Interface and Technical Design
    The next step is to create a user interface design for each software component and design technical architecture to identify the working of a dApp.
  • Development and Deployment
    It is a crucial step in dApp development where blockchain developers start building the application using the agile development methodology. After the app is tested on the test network. developers deploy them on the main net and cloud platforms. 

What factors make a company the best dApp Development Company?

When it comes to looking for a decentralized app development company, you should identify if the company is excel in building web and mobile apps for your project development. The company should also have a team of dApp developers who are skilled in developing blockchain apps and know how to work on different blockchain platforms like Stellar, Tezos, EOS, Hyperledger, Corda and Tron. 

Another factor that makes a company the best decentralized application development firm is the number of blockchain projects they have worked on. 

What will be the cost to hire dapp developers?

The cost of building a dApp depends on the client’s requirements. dApp can provide anything from being able to take in hundreds of users to a million users depending on the business requirements. Therefore, the cost of hiring dApp developers is decided on the basis of factors like tech stack and your project requirements.
