Cryptocurrency Ecosystem 

The advent of cryptocurrencies has led to the creation of a new ecosystem of applications that allow users to store, manage and trade their digital assets. One of the essential components of this ecosystem is the crypto wallet app. Crypto wallet apps enable users to securely store their cryptocurrencies, view their balances, and make transactions. In this case study, we will discuss the development of a crypto wallet app that includes the integration of third-party APIs, smart contract calls for swap, and the integration of the Ethereum and Binance Smart Chain (BNB) mainnet.

Project Highlights

  • The project involves developing a blockchain-based application that enables users securely send, swap digital assets, add and receive token, generating seed phrase and wallet development. 
  • The app is built using Android Kotlin, Swift iOS, Python API, Coin market third-party API, MySQL DB, and a public blockchain smart contract. 
  • The app has an intuitive user interface that makes it easy for users to navigate and perform various tasks such as send, swap and transferring cryptocurrencies.
  • The app leverages blockchain technology to ensure the security of user transactions. The use of public blockchain smart contracts ensures that all transactions are transparent and immutable. 
  • The app integrates with Coinmarket third-party API to provide users with real-time updates on cryptocurrency prices and trends. 
  • The app’s backend infrastructure is built using Python and MySQL DB. This ensures that the app is scalable and can handle large volumes of transactions. 
  • The app’s public blockchain smart contract is written using Solidity, a programming language specifically designed for Ethereum smart contracts. 
  • The app undergoes rigorous testing to ensure that it is free of bugs and vulnerabilities. It is then deployed to a production environment where it can be accessed by users. 
  • The app requires users to register and authenticate themselves before they can use the app. This ensures that all transactions are carried out by verified users. 

Our Client

Our client, a startup company in the cryptocurrency space, approached us with the idea of developing a crypto wallet app that could enable their users to store, manage, and trade their digital assets. They wanted the app to be user-friendly, secure, and robust. They also wanted the app to be able to integrate with third-party APIs such as Coinmarketcap, allowing users to view real-time market data for various cryptocurrencies. 

Client Requirement

  • Secure and reliable transactions  
  • Real-time updates on cryptocurrency prices 
  • Support for multiple cryptocurrencies 
  • Smart contract development  
  • Robust security and compliance measures  

Proposed Solution to fix operational process

Based on the client’s requirements, we proposed to build a blockchain app that is user-friendly, secure, and reliable. To achieve this, we recommended developing the app using Kotlin for Android, Swift for iOS, and Python for the backend API. The app would also integrate with third-party APIs, such as Coinmarket, to provide users with real-time updates on cryptocurrency prices and trends. To ensure the security and reliability of transactions, we proposed implementing features such as two-factor authentication, encrypted communications, and robust backend infrastructure.  

We also recommended including public blockchain smart contract development to ensure transparent and immutable transactions. To support multiple cryptocurrencies, the app would be designed to allow users to store and transfer a variety of digital assets, such as Bitcoin, Ethereum, and Litecoin. Additionally, the app would be customizable, allowing users to choose their preferred settings and features. 

Why we chose this solution: We chose this solution based on the client’s requirements for a blockchain app that is user-friendly, secure, and reliable. We believe that building the app using Kotlin for Android, Swift for iOS, and Python for the backend API will provide a solid foundation for a high-quality app that is well-suited for mobile devices. These technologies are widely used and have proven to be reliable and efficient for app development.


Integrating with third-party APIs such as us to provide real-time updates on cryptocurrency prices and trends, which is an essential feature for any cryptocurrency-related app.


Additionally, the inclusion of public blockchain smart contract development will ensure that transactions are transparent and immutable, which is critical for maintaining user trust and security.


By supporting multiple cryptocurrencies and allowing for customization, we ensured that the app is accessible to a wide range of users and meets their individual needs.


The development of the app for both Android and iOS platforms allowed us to reach a larger user base.


By implementing robust security and compliance measures and offering technical support, we can ensure that the app is secure, compliant with relevant regulations and standards, and user-friendly.

Key Features


  • 01. Decentralization

    Blockchain technology is often associated with decentralization, which means that it operates without a central authority controlling it. This feature is often used to ensure security, transparency, and trust in the project.

  • 02. Smart contracts

    Smart contracts are self-executing contracts with the terms of the agreement directly written into lines of code. They can be used to automate processes, enforce rules and regulations, and eliminate the need for intermediaries in transactions.

  • 03. Tokenization

    Tokens are digital assets that can represent anything from a cryptocurrency to a real-world asset like property or shares in a company. Tokenization can be used to enable fractional ownership, simplify asset transfer, and increase liquidity.

  • 04. Crypto Swap

    Instantly exchange cryptocurrencies in a seamless and decentralized manner. Swap between digital assets with ease and convenience. Benefit from competitive rates and secure transactions, empowering users to manage crypto portfolio efficiently.

  • 05. Seed Phrase Generator

    The seed phrase generator uses cryptographic algorithms to generate a random and secure set of words. It can be used to restore or recreate a wallet in case of loss, theft, or damage to the original wallet.

  • 06. Wallet

    A wallet is a digital application or device that enables individuals to securely store, manage, and transact with their cryptocurrencies. It provides a user-friendly interface for accessing and interacting with digital assets. It allows users to send, receive, and monitor their cryptocurrency holdings.

  • 07. Interoperability

    Interoperability refers to the ability of different blockchain networks to communicate and work together seamlessly. This feature is important for creating a robust and interconnected blockchain ecosystem.

  • 08. Privacy

    Some blockchain projects prioritize privacy and anonymity for their users, either through the use of advanced encryption techniques or by enabling privacy-focused transactions.

  • 09. Scalability

    Scalability refers to the ability of a blockchain network to handle a large number of transactions without slowing down or becoming congested. This feature is crucial for ensuring that the network can support a growing user base and remain efficient over time.


Benefits of Solution

By having a website, users could access the platform from any device with an internet connection, without the need to download and install a dedicated app. This helped to increase the reach of the platform and made it more accessible to a wider range of users. With a mobile app, users can access the platform from their mobile devices, making it more convenient to use and access on the go. This can increase the frequency of use and user satisfaction. 


The Result

We did not only meet the clients’ expectations but exceeded them. The client was delighted to get the right solution for their business.
