STM.Wallet 2.0

Мobile wallet iOS/Android

Project

STM.Wallet 2.0 is a decentralised crypto-wallet app for iOS/Android for storing, sending, receiving and interchanging cryptocurrencies as well as exchanging fiat money.

STM.Wallet 2.0 is currently published under WIN.Wallet and is an upgraded version with the extended functionality of the STM.Wallet 1.0.

We upgraded design and functionality, bringing it to a new level of user-friendly UX/UI. This wallet app is written in a modern technology stack flutter/dart.

Users can make transactions in BTC, ETH blockchain networks and work with STM, IDRT and ERC-20 tokens. They also can import and export their wallets. All the data is stored locally on the users’ smartphone.

There is no need to log in to the system to use it, and users can send and exchange fiat money and cryptocurrency in two clicks with their bank card and smartphone.

Users can find the transaction recipient by email; this function solved the problem of remembering the wallet’s lengthy numbers.

Completed tasks

We developed a modern, user-friendly UX/UI interface.
We developed a cross-platform solution.
We integrated the app with blockchain networks Bitcoin, Ethereum and customised the BD responsible for blockchain interactions.
We developed and implemented a storage function for storing and managing the ecosystem’s token – STM.
We developed a decentralised storage system for crypto-wallets’ data. All private data is stored locally on the user’s smartphone.
The ERC-20 tokens are supported in the app. Tokens are automatically added to the Ethereum wallet and are ready for transactions.
We added the option of transactions without the waiting time from the previous transaction “mining”.
We added an exchange rates function in the app.
