GetLogin Mobile

GetLogin Mobile is a single sign-on solution for decentralized applications.

With it, you can authorize third-party mobile applications to work on your behalf with the safe allocation of cryptocurrency for these actions.

Gnosis Chain is used as the blockchain. The application has built-in support for the BZZ token from Swarm. With this combination, developers can create applications that use not only decentralized finance, but also storage.

BZZ tokens are used to pay for storage. With the help of them you can pay for the download and upload of data. Despite the fact that at the moment the node and gateways do not support the mechanism of direct payment for data operations, such a mechanism is under consideration by the application developers.

With this combination of technologies, applications can be built that can act as a secure cloud for your data. You can store any kind of files: music, video, photo. You can securely share files with other users, store application settings, and so on.

Application sessions

Application session is an Ethereum-based wallet that is funded with a safe amount of funds. The address is registered in the smart contract as an address operating on behalf of the user. Such an address can be checked for validity in smart contracts created on Solidity.

An example of such a smart contract can be seen in the demo project.
