[mazurroman]

Brainstorm this up. We need the playground to make this more clear.

The user needs to understand who is receiver, who is sender and who is composer.

Idea

FEEDBACK FROM MARIJA: Executing Account – the label suggests that it's the sender of the transaction. We should rename it to "Receiving Account" to make it crystal clear.
