A dead drop is a spy technique used for anonymous information exchange. I tried to create place to host such exchanges. Only requirement to stash or read a message is to know the location. I used What 3 Words grid system as it offers more precise locations and overall more than 50 trillion possible places to stash messages.

It ain't much, but I would like to hear your thoughts on it.

"Enter the coordinates of a dead drop to check if it's hot (has stashed message)"

I entered ///limit.broom.flip as the co-ords.

It said it was empty.

So I wrote "This is a secret message!"

>Message stashed at ///limit.broom.flip >Your dead drop is hot.

In another browser, private window I went to https://www.dpolakovic.space/dead-drop and again entered ///limit.broom.flip

I see "This is a secret message! and a button to "Burn message"

How is this better than OneTimeSecret?

The difference would be, that message could be shared in coordinates, not the link itself. This implementation on my site is just prototype.

Gotta be honest, I'm not entirely following this.

Is there an usage example?

Idea was, that just like with spies - if you have a medior component in communication, you can communicate without knowing who is on the other side. This medior would only tell you the location where the message will be hidden (stashed). Like when two spies exchange information without meeting each other.
