Success Stories

Bitcoin Wallet

The first Bitcoin Wallet with a Private Key Recovery – a unique bitcoin solution, that our tech team helped develop from scratch.

Some of the main benefits of Tatoshi Wallet:

  • Recovery Functionality for Private Keys Store your back-up data with your friends & family and use them in case you need to recover your private key. Your Protectors will never have any access to your Bitcoins.
  • Non-custody Storage You are always in full control of your private key. Nobody except you has ever access to your funds. As there is no centralization of assets, the risk of attracting hackers is minimized.
  • Usability Comparable To Messenger Apps Designed to be usable for everyone. You do not have to be a tech nerd. Our usability is similar to well-known messenger apps. Sending Bitcoins is as easy as sending a message.

    ‘Simple Task supported our Blockchain project from the initial idea to its final realization. We have built the application from scratch and used Swift and Objective C for mobile development, and for the backend part, we have used Java and Docker. I have found Simple Task to be very professional, proactive and great to work with.’
