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.

We create, deploy, debug and test smart contracts written in Solidity language on Remix, a browser-based IDE. It can connect with Ethereum Blockchain via Metamask.

Back-end Programming Languages We Understand


We write smart contracts for blind auctions, voting, multi-signature wallets and crowdfunding in Solidity programming language. Solidity is an object-oriented language that supports libraries, inheritance and user-defined types.


Our developers understand Golang and use it for writing chaincodes in Hyperledger Fabric. It is an open source and statically typed programming language which is platform independent.


Rust is a multi-paradigm, high-performance, statically typed programming language. With a primary emphasis on safety and performance, this language assists developers in developing stable and resilient apps.


We use JavaScript language to store all the code of a dApp. It is a dynamic and prototype-based language that supports object-oriented and declarative styles.


We utilize Java programming language to write code for microservices to be used in a dApp if required. Also, various SDKs for different blockchain platforms are written in Java.


Our developers also understand Node.js which can be used to build backend of real-time multi-user decentralized applications.

Front-end Development Stack We Follow


We simplify the development of dynamic web dApps with a feature-packed JavaScript framework, Angular.js.


We utilize an open-source toolkit, BootStrap, which allows us to build a decentralized and responsive website using HTML, CSS and JS.


Since jQuery is light-weight and supports a wide range of plugins to present special effects in the web apps, we utilize it while building decentralized web applications for clients.


We use React, an open-source JavaScript Library, to build user interfaces for single page applications. It can be used for managing the view layer for both web and mobile apps.

We leverage high-performance cloud services to deploy and manage enterprise dApps


Our dApp Development Team uses Amazon Web Services (AWS) to deploy dApps built on various platforms including Hyperledger Fabric/Sawtooth, Ethereum and Corda worldwide in a few clicks.

Google Cloud

We also use Google Cloud’s Blockchain Kit to build and deploy blockchain apps with a unique feature “Pay-as-you-go.”

Microsoft Azure

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.
