What was the first Propy real estate transaction?

Could you please elaborate on the first real estate transaction that was facilitated by the Propy platform? How did it come about? What were the key players involved? Were there any challenges or unique aspects to this transaction that set it apart from traditional real estate transactions? And finally, how did the use of blockchain technology play a role in making this transaction possible? I'm particularly interested in understanding the specific details of this milestone event in the world of cryptocurrency and real estate.
