A wallet application for Ethereum and ERC-20 transactions


The Brief

As the crypto industry competes with traditional financial institutions, the demand for apps that perform cryptocurrency payments and exchange continues to grow. Our Australian business partner aims to provide a solution that renders Ethereum and ERC-20 transactions quickly and simply.










Planning stage

During the planning stage, our professionals determines the product scope, architecture, budget and timeframe for development.

We clarify the development workflow and provide a demonstration fully outlining how the app will look and feel. The development process follows this established roadmap, guaranteeing no unexpected delays or additional expenses during development.

Technological challenges

We provide our clients with a clear development plan to aid in efficient organization of resources. We are obligated to deliver both accurate pricing estimates and a working prototype.

Powerful UI/UX design pattern

Embracing both minimalistic and contemporary strengths, we provided two versions of the app – light- and dark-themed - to meet varying user preferences.

Total security

Wallet passwords are stored on a dedicated server and only the crypto wallet owner may access them through the CryptoTap app.

Blockchain implementation

Correlation with Blockchain via Blockchain connector is provided, utilizing a web3js library for RPC calls that are connected to a public blockchain node.

High level of interaction with other services

Interaction with the server application is completed via HTTP (SSL) protocol. The finished app will also connect with external services responsible for push notifications (OneSignal or FCM).
