Components
eSteem is a cryptocurrency-based application blend of blogs and social media in compilation into a modern app that benefits users.
Proposal
My suggestion is to add QR code to easily add friends in eSteem app, with this feature eSteem user easier to add friends do not need to memorize and write username.
Mockups / Examples
The photo below is the basic view of the app before the feature is added.
The photo below is the design view I recommend.
The photo below is the view when the user presses on the QR code.
Benefits
The benefits of this QR code are to quickly add friends so that users can more easily add friends, and to avoid manual typing by users. because in general the username is a unique address to differentiate with other users. So it's safer so no need to type username again, because it can be scanned through the user QR code.
