I need an application for Android.
I just want an application that allows you to:
1). Buy cryptocurrency Via Admin
2). Sell cryptocurrency in USD + FIAT Via Admin
3). Merchant = User can connect his store to us and can use BTC cryptocurrency, Token ERC20. ===> You to rent my application to the business or warehouse for customer use and I get a commission for its use.
4). Buy and sell through third parties (Changelly API)
5). Transaction security uses the fingerprint sensor on your mobile screen,
Note: You may use the open source code from Github and modify it and the most important thing is the code script must be clean (WITHOUT BUG)
