Abstract: Methods, systems, and devices for data management are described. A blockchain address application may receive a user input to exchange a first amount of a crypto token from the blockchain address application for a second amount of a fiat. The application may display, at a user interface after receiving the user input, an estimation associated with the exchange of the first amount for the second amount. The application may receive another user input to confirm the estimation and transmit, to a custodial token platform, a request to initiate the exchange. The request may cause execution of an on-chain transfer of the first amount of the crypto token from a first blockchain address of the blockchain address application to a second blockchain address associated with the custodial token platform and execution of an off-chain transfer of the second amount of the fiat from the custodial token platform to an external entity.

Abstract: A method and system for browsing and navigating web pages on a small screen device using a keypad are disclosed. A web page is divided into logical sections. In one embodiment, each section is mapped to at least one key on a keypad, such that when a user presses a key, the corresponding section of the web page is displayed on the device's display panel. In another embodiment, each section is mapped to a symbol which can be remembered by the user. The user then selects the symbol corresponding to the section of the web page that he or she desires to view. As each section of the web page is being viewed, an icon may be included on the screen to indicate that portion of the web page that is being viewed.
