Client Requirements

In this digital era, there are not even a few things that you have to do without the help of digital. Technology has even made the financial transaction quick and effortless with services like net banking, UPI and even digital coins. One can even showcase their skills by developing digital art, GIFs, video, etc. Many people even trade these digital arts in exchange for digital coins. One of our US-based clients who is extremely knowledgeable and passionate about blockchain technology approached SwissCode with a mobile application idea. He wanted to develop a platform where users can trade their digital artwork using NFT. Along with that, it should allow users to create and trade their NFT using all three methods as mentioned above. The platform should also allow users to trade NFT with digital cryptocurrency coins like Matic with the use of blockchain. The platform should also allow users to add and withdraw cryptocurrency for buying NFT.


In this NFT based mobile application, We have developed some classic and simple user-side features such as login, registration, post creation, bid and buying as per client requirements. The client also wanted home and feed posts where users can see other users’ posts and update their own profiles. Our team of developers has the below-listed features for the mobile application.

1. Decentralize the Large size of the image

The primary requirement of the mobile application is to trade the digital arts using blockchain. The blockchain works on a decentralized approach. Each digital art image can be large that can encounter problems while saving the image. So our mobile app developers came up with the solution to use IPFS to store large-size images and decentralized things.

2. To Manage Raffle winner

Another application requirement that allows users to create a raffle for NFT, where users can buy a ticket for the NFT and announce the lottery winner after the designated time. Our developers encounter the challenge of creating an algorithm for the winner that they resolved by developing a custom algorithm specifically for the mobile application.

Project Approach & Results

As we are aware, blockchain is not the most scalable ecosystem currently. it always encounters problems like slow indexing at the time of creation, block size restrictions, multiple edition creation, etc. All these problems demand a unique solution to provide an impeccable user experience. So the client approached SwissCode with this great idea to develop a unique, secure and scalable NFT marketplace – *****.

So, our aim for developing this marketplace was to resolve all the mentioned issues using different frameworks and approaches. To begin with, we created a file with the complete details covering all these points, scenarios, problems, flow charts, and SRS. After finalizing the document, Our Mobile app designers started working on the app design phase. After getting approval on the final app design, our app developers move ahead with the development phase. The Mobile app developers started their development process by choosing the best-fit technology for android, iOS and the admin panel.

We chose native technology swift for iOS development and Kotlin for android development and used JSON-based rest API development with Node and Laravel Framework. SwissCode developers used Angular 9 to create an admin panel for basic tasks such as managing users, posts, reports, etc. We used web3 for calling the smart contracts with the help of solidity. Our app developers had used Magic SDK for passwordless authentication providing secure login. Any existing blockchain apps usually face the problem of poor user experience. Our app developers eliminated that with the help of a Matic network to deliver an exceptional user experience.

After the development phase, our QA team tested the mobile application before finally delivering it to the client.
