WLLT

A user-friendly secure ETH wallet and payment app, that enables users to manage their ETH wallets as well as ERC-20 tokens.

  • Project Challenge

    Our team provided a secure environment for crypto-assets management. One of the biggest technical challenges for our mobile team was to arrange the transaction that will be executed as fast as possible, using ETH cryptocurrency and ERC-20 tokens. Moreover, this application needed to enable importing existing wallets and creating new ones, shielding them with advanced security settings.

  • Design Challenge

    The application’s design had to meet the next requirements: have blue and white as predominant colors, be eye-pleasing and not overflown with crypto-information since this application is aimed at average non-expert users.

Wireframing

Not a single UI/UX design creation process can skip the wireframing stage. WLLT wireframes formed a “skeleton” for the future visual design. Wireframes gave us more freedom and flexibility since it is easier to adjust black-and-white schematics pictures with basic elements than to change the whole UI design after it’s concept has been formed and drawn.

ETH Wallet

We’ve developed a scalable mobile application for the Android platform. By far it supports only ETH and ERC-tokens, but our team is already working on implementing other cryptocurrencies in the application. The application is safe, with advanced security settings. The application gives users the opportunity to execute fast crypto-transactions and get push-notifications every time he receives assets. There is a unique “trick” - “watch-only” wallets - users can trace the transaction history of any wallet in the network provided that they import it in the app via the public key.

Interface of user wallet

Send & Receive ETH

Easy and fast transactions between any existing ETH wallets. Quick transaction info filling via QR-code scanning - no need to enter the wallet address manually, just use the scanner, or show your QR code to the addresser to receive the funds sooner. The same applies to ERC-20 tokens: the application has its own database of tokens, but you can add others to the list via its contract’s address.

Transaction History

The application gives you full transparent view on your transactions and the “watch-only” wallets transactions with maximum information presented in a perceivable way. Moreover, user can add their custom notes to any transaction to make them more distinguishable.

Result

The WLLT’s MVP is already on the Google Play market with all the features described above. At the moment we are working on implementing new features, such as:

  • BTC support in app
  • The ability to buy crypto-assets via credit and debit cards
  • Translating the application to more languages
  • Cryptocurrency exchange functionality
