What are Decentralized Applications

DApps are open-source applications that are used to interact with smart contracts running on a peer-to-peer network of servers. These applications can be based on a variety of blockchain platforms such as Ethereum, NEAR, Polkadot, EOS, and others. Since dApps don’t rely on central servers, this vastly reduces the risk of failure, making them more reliable than traditional applications. By eliminating the middlemen between users and service providers, dApps allow for greater freedom, openness, and transparency while also reducing the risks associated with handling user data. Due to their nature, developing a dApp is a rigorous process that requires a lot of attention and care. Part of the reason for this, is that once a dApp (and the underlying smart contract) has been deployed, it is difficult to introduce fixes and major updates. For this reason, it is important that your dApp is developed professionally.

Benefits of dApps for Your Business


Decentralized applications are powered by smart contracts – self-executing contracts written in code that provide automation. This can drastically reduce transaction costs and enable frictionless peer-to-peer transactions. They also reduce costs associated with employees, auditors, and legal advisors.


The use of a blockchain eliminates the need for users to create accounts. The dApp recognizes blockchain-validated cryptography, facilitating greater privacy and ease of use.


DApp data is stored on a public ledger that records everything in a secure and transparent way, guaranteeing that it cannot be manipulated. This creates openness and transparency while eliminating the need for middlemen. The ledger can be checked and audited by anyone as it is open source, which allows participants to truly understand how the application works, or even to improve it by finding and fixing bugs.

User governance and autonomy

Due to their decentralized nature, dApps function on the basis of consensus by all users, which guarantees that no one can dominate and act as a gatekeeper. This includes consensus about the cryptographic algorithm that is used to show proof of value. Consensus is also required when any changes are made to the code of the dApp itself.

Fault tolerance

Because dApps are decentralized rather than being based on standard client/server networks, no single node controls all the transactions or records. In other words, there is no single point of failure that can crash or sabotage the whole app. As a result, dApps are both more stable and safer than traditional apps, do not need downtime, and provide constant access.

Dapp development Process


Gather requirements and run business and technical analysis.

Our analysts and engineers discuss your requirements in order to understand the business conditions and propose a solid concept and solution that defines the entire scope of work.

Architecture design

When the use case has been determined, the dApp architecture is designed. The purpose of this is to create a Proof of Concept (POC), and demonstrate how all of the parts of the dApp will fit together. The architectural design also includes a plan for how the frontend layer, user interface, and backend layer (smart contracts, storage, and blockchain) will interact with each other.

Low- and high-fidelity designs

After the architecture of the dApp has been agreed upon, both low and high-fidelity design prototypes are created. Fidelity design includes elements such as visual design, content, and interactivity. The initial low-fidelity design is used to further flesh out how the app will look and work. After this has been finalized, a high-fidelity design is created that results in a clickable prototype.

Development of smart contracts / wallets

The next step involves the creation of the smart contracts that will connect the dApp to the blockchain and execute the business logic and functionality of the app. Wallets are also developed at this stage to enable the exchange of tokens within the dApp.

Backend / frontend development

At this stage, the fidelity designs are moved to the development stage and the frontend and backend are finalized. The frontend can be created in any programming language that can make API calls to the backend.

Internal audit

An internal audit is conducted to review the previous development stages and establish if all requirements and specifications have been met. During the audit, tests are also conducted to check how the various parts of the dApp work together.

Testnet deployment

After the audit is completed, and any potential issues have been identified and resolved, the dApp is deployed on a testnet. This allows developers and clients to test the dApp at no cost, and to evaluate whether it works as planned.

Mainnet deployment

The dApp is deployed on the mainnet on which it will function, and becomes available to users.

Perfectus can develop some of the most popular types of DeFi applications, including:

Use Case: Reward dashboards are connected to token contracts (reflection tokens or reward token contracts) so that any token holders can connect their wallets and check their token investment value, see their rewards, and locate any other details related to the token, all updated in real time. Holders can manually claim rewards by interacting with the platform and paying a gas fee. The calculator is for investors to check their rewards against their investments on a daily, weekly, monthly, and yearly basis, broken down by token volume. Features:
  • Full interaction with token smart contracts 
  • Total visibility of distribution amounts by user, with detailed breakdowns
  • Manual claim option for users

Number of projects completed: +20 View Projects
Use Case: APY platforms are also connected to token contracts, (rebase contracts) so holders can connect their wallets and check their investment value and track their rebase rewards in real time. The platform interacts with the contract, and investors can see all the contract details, as well as a prediction of the rebasing rewards they will be getting per day, week, month and year. Features:
  • Full interaction with token smart contracts 
  • Rebase time visibility with reward loops
  • User-specific rebase time visibility 
  • User-specific rebase reward prediction against the invested value 

Number of projects completed: +10 View Projects
Use Case: A staking platform is a crypto exchange, broker, or app that lets you earn rewards on cryptocurrencies. To earn rewards, you commit your cryptocurrency to the platform, which is known as staking. That platform then pays you a rewards rate on your deposit. Features:
  • Staking smart contract
  • Multiple pools and lock periods 
  • Staking rewards
  • Dynamic APY calculation for pools
  • Fixed APR set up with lower and upper boundaries
  • Fixed APY set ups 
  • Any features upon client requests

Use Case: The lottery mechanism has been developed as one of our key products, and the mechanism is that the lottery pool is being accumulated with given crypto tokens/coins, and all holder details are getting checked in realtime whether all eligible conditions are fulfilled to be part with the lottery. Once the lottery is drawn, 5 to 20 (adjustable) lucky winners are getting selected and populated with their wallet addresses on the screen in descending order with reward amounts. Winners can connect and claim their rewards if they are lucky winners.


  • Smart contract for the lottery pool
  • Lottery eligibility mechanism 
  • Realtime data sync
  • The lottery drawing mechanism randomly selects given users 
  • Lottery winning amount distribution

Use Case:  The private sale launchpad is for projects to raise funds from investors by creating pools and allowing them to claim tokens/ coins as Initial Coin Offerings. The resulting funds can be easily claimed by project owners and utilized  for marketing and development before moving onto the public sale or launch stage of the project.



  • Launchpad smart contract
  • Multiple pool creation for tokens
  • Technical fundraising
  • Vesting periods
  • Reward claim feature 
  • Token claim features 
  • Insurance funds for investors

Use Case:  As with private sale launchpads, a presale sale launchpad is for projects to raise funds from investors by creating pools and allowing them to claim tokens/ coins as Initial Coin Offerings. But in this case, the resulting funds can then be utilized for token liquidity on DEX platforms, and for marketing and development.


  • Launchpad smart contract
  • Multiple token pools
  • Vesting periods
  • Dex listing and auto liquidity
  • Token claim features 
  • Insurance funds for investors

Use Case: Decentralized exchanges, also known as DEXs, are peer-to-peer marketplaces on which cryptocurrency traders make transactions directly without surrendering the management of their funds to an intermediary or custodian. These transactions are facilitated through the use of self-executing agreements, written in code called smart contracts. DEXs fulfill one of crypto’s core possibilities: fostering financial transactions that aren’t officiated by banks, brokers, payment processors, or any other kind of intermediary. They were created to remove the requirement for any authority to oversee and authorize trades performed within a specific exchange. Decentralized exchanges allow for the Peer-to-Peer (P2P) trading of cryptocurrencies by directly linking buyers and sellers. They are usually non-custodial, which means that users keep control of their wallet’s private keys – a type of advanced encryption that enables users to access their cryptocurrencies. Users can immediately access their crypto balances after logging into the DEX with their private key, and they will not be required to submit any personal information like names and addresses, thereby providing the benefit of ultimate privacy.


  • Swapping
    • The platform is an open-source DeFi protocol designed especially for swapping BEP-20 tokens. Anyone can use the platform and swap BEP-20 tokens on the exchange, which is built on Binance Smart Chain.
  • Addition of Liquidity
    • Our DEXs work on the AMM model, allowing traders to swap tokens without an order book. You simply select the token pair that you wish to deposit and add liquidity to the exchange. Users should always make sure they understand the concept of impermanent loss before adding liquidity to a pool.
