Cryptocurrency e-Wallet Application Ecosystem for a Global FinTech Enterprise

Solution Overview

The solution includes web, mobile, and kiosk-embedded application clients with similar functionality, alongside a web interface for administrators and a cloud-based backend API server.

Client Subsystem 

Client applications enable users to create new accounts through a simple registration process and KYC (Know Your Customer) verification. Once registered, users gain access to their crypto wallet, allowing them to perform various functions:

• Create and manage multiple wallets 
• Buy and sell cryptocurrencies and other digital assets
• Monitor account balances and transaction history
• Connect their traditional bank account using Plaid
• Deposit and withdraw both cryptocurrencies and fiat currency
• Locate nearby kiosks through a built-in kiosk locator

KYC verification is conducted through integration with ZeroHash KYC Service. The process requires users to provide identification and a selfie, which the system compares against the ID photo. It also checks the user against various databases such as OFAC and FinCEN to ensure compliance with strict financial regulations.

Admin Subsystem

In this subsystem, support can control the workflow of client wallets. They can monitor the following aspects:

• User details
• Client status
• KYC (Know Your Client) status
• Reasons for KYC rejection

Project Challenges

The project faced significant challenges primarily related to the integration with the cryptocurrency platform. At the time, the provider had not completed the necessary integration with the company’s systems, leading to uncertainties that complicated the development process.

Key issues included inconsistencies in their documentation, bugs present on their side, and repeated postponements of releases, as they were developing certain functionalities specifically for the project. These integration delays had a notable impact on business goals. As a result of the setbacks, the team experienced prolonged idle periods, increasing the timeline for minimum viable product (MVP) production from three months to four. Moreover, delays in data provision from the provider led to inefficiencies among the engineering team, resulting in additional expenses that pushed the budget above initial forecasts.
