NEX-FS07-#
NEX App Requirement - Wallet Functions
The keyword shall indicates a requirement statement.
The keywords may, could, and should are not requirements but rather indicate items related to requirements that are worthy of consideration.
5. Process Overviews
The processes which will be described here are as follows.
sending assets
receiving assets
5.1. Sending Assets
The user navigates to the wallet send function.
The user reviews their assets available to send.
The user selects an asset in the asset selection field.
The send form updates as necessary per the selected asset.
The user enters an amount of available asset to send in the amount field.
The send form updates as necessary per the user inputs.
The user enters the recipient account name into the to field.
The user selects which blockchain to send the funds to, if withdrawing to a sidechain.
The user may enter a memo if sending assets within the Peerplays network.
The user reviews the send transaction information, such as fees, total costs, and estimated confirmation time.
The user initiates the transaction by clicking the “send” button.
The app displays a confirmation dialog to the user.
The user reviews and accepts the confirmation.
The app signs and sends the transaction to the blockchain.
Upon success, the app displays a success message to the user and updates the user’s available balances.
5.2. Receiving Assets
The user navigates to the wallet receive function.
The user selects an asset in the asset selection field.
The receive form updates as necessary per the selected asset.
The user reviews the instructions for receiving the asset they selected.
If the selected asset is BTC, the app displays their BTC deposit address and allows the user to cope the address to their clipboard.
If the selected asset is BTC and a BTC deposit address is not yet associated with the user’s Peerplays account, the app displays a “Generate Bitcoin Address” function.
The user clicks the “Generate Bitcoin Address” button.
The app generates a new BTC deposit and BTC withdraw address, displays the BTC deposit address to the user, and displays a download link for the deposit and withdraw address private keys.
The user downloads their private keys.
6. Context
The wallet is at the heart of the app. It’s the way assets can come and go from the market. Using the wallet, users can work seamlessly with sidechain assets like BTC and HIVE. These assets can then be traded in the open exchange, sent around the network, and even sent back to the sidechains.
7. Design Wire-frames
The original designs for the NEX app wallet functions are available here:
Here are updated wire-frames for the design covered in this FS:
