TX.Mobile
Read full descriptionHide full description
TX.Mobile is for users to store and back-up private keys and to sign generic Ethereum blockchain transactions on applications built on TEOS. TEOS is Token Economy Operating System, a blockchain infrastructure allows businesses to tokenize, document and trade any products or services. TEOS based applications execute blockchain transactions. Each transaction needs the authorization from a private key. Thus having private key information means having the right to approve transactions of digital assets, regardless if the private key is in the hands of the rightful owner. With TX.Mobile, users can safely store their private keys in their own smartphone devices with full encryption. A back-up function allows users to restore their private keys in a new mobile device when the old one gone missing. They can create as many keypairs as they want, and pair them with the CoreLedger infrastructure. Although the App stores usersβ private keys, it does not share the information nor sign transactions by itself. Users have full ownership and control of their own private keys.
