In addition to this, users can also take benefit of a currency exchanger in the app that will enable them to exchange their money in different currencies like British Pound (GBP), Australian Dollar (AUD), Danish Krone (DKK), US Dollar and other currencies with low exchange fees. Even, users of this app can also convert cryptocurrencies like Bitcoin and Ether.

Client’s Requirements

When our client first contacted us, he proposed he wanted a multi-currency and cryptocurrency mobile wallet application that revolutionizes the way people send and receive money. He wanted one such solution that helps people to send and receive both currencies and cryptocurrencies like Bitcoin and Ether worldwide.

Through his idea of mobile wallet app, he wanted to eradicate the need of downloading multiple apps that support different currencies and cryptocurrencies. He wanted to provide a mobile solution that solves different problems like sending and receiving currency and cryptocurrency across the world, high exchange fees that people pay while exchanging currency and other problems.

In short, he needed a single wallet app, supporting maximum currencies and cryptocurrencies of the world so that people do not face any problem while sending and receiving money.

Our Proposed Solution

After listening to our client’s app idea and requirements about multi-currency and cryptocurrency solution, we researched and reviewed top cryptocurrency wallet apps like Coinbase and Local Bitcoin that widely used by people to send and receive cryptocurrencies like Ripple, Bitcoin, Litecoin and other cryptocurrencies.

After researching and analyzing different solutions, our dedicated team of blockchain developers made one proposal named Currency Tracker solution, a multi-currency and cryptocurrency app that supports both currencies and cryptocurrencies. The application will enable people of different countries to send and receive currency/cryptocurrency, exchange money from one currency to another with low exchange fees.

Impressed by our proposal, our client asked us to go ahead with the app development and within one month, we delivered a multi-currency and cryptocurrency wallet app named, Currency Tracker application with a comprehensive range of features. Our developed application is a highly safe and secure solution for money transfer to bank account in more than 120 countries as this application has its own server rather than any third-party server.

Different Challenges & How We Solved Them



The main challenge that our blockchain engineers faced in this project was creating a Bitcoin server because our client wanted to have its own Bitcoin server rather than hosting it on any third-party server.

The reason behind it was that every bitcoin wallet app has its public and private keys, but in case if we had used any third-party server, our client would not got those private and public keys with him, but he wanted to keep those private and public keys with him in hard copies, giving more safety and security to end-users.

How We Solved It?

Being a one of the best blockchain app development companies in India, we researched and understood about bitcoin market and its server in detail and ultimately developed a bitcoin server for our client.



Apart from this, another major challenge that faced by our blockchain consultant was the deadline of this project. Our client asked us to complete this project in just one month as he wanted to participate in the ICO (Initial Coin Offering), a new financing mechanism used by enormous startups to raise millions of dollars. So, developing a multi-currency and cryptocurrency wallet app in just one month can be a quite challenging task for any Blockchain Developer.

How We Solved It?

To solve this challenge, we assigned 1 dedicated iOS developer, who has more than 2 years of experience in iOS app development for varied categtories. He researched how entire blockchain technology works and differentiated about cryptocurrencies like Bitcoin and Ether to develop a high-end multi-currency and cryptocurrency wallet app. At last, our assigned team for this project developed the major part (Bitcoin server) of this app in just one month.

Appreciation from Clients


Douglas Laver


The Space-O team were great to work with. Every part of the process went as per the agreed schedule, and the finished prototype met, and in most cases, exceeded my expectations. While Space-O wasn’t the most price competitive of the quotes I received, the quality of their work, professionalism, and product, was well worth the additional cost. Highly recommend, and will continue to use their services for future projects.
