Double drops
Basic, a clean typography, smooth colors and a double drops visual.

Solution

First a clean typography for a good legibility of the name.
I think it's a essential part of a logo creation.
For the visual, two drops. That symbolize for me the transfer between two users using Dead Drops. Same idea for the two colors Orange an Pink relied with a gradient, connoting the connection, the exchange. I choose this two colors for here energy and here legibility. And the two "D" write in the big drop recalls the initials of "Dead Drops".

I create a Black and white version too.
