On the 17th of July, 1975, two mission commanders, Stafford and Leonov, exchanged the first international handshake in space through the “open hatch” of the Soviet Soyuz 7K-TM spacecraft. Nasa publicly referred to this mission as Apollo 18; respectively, the mission under the Soviet Soyuz programme was given a number designation of Soyuz 19. The Apollo-Soyuz handshake was symbolic of something much more significant than simply being the first international handshake in space; it was a symbol of détente (the easing of hostility or strained relations) between two nations that were in opposition during the Cold War. In likeness to the Apollo-Soyuz handshake, through the use of OpenHatch, users will be able to shake hands on business arrangements so as to achieve a common goal.

### OpenHatch today

OpenHatch is Messier's **non-custodial escrow** for peer-to-peer (P2P) and business-to-business (B2B) deals. It covers digital assets, services and real-world assets (RWAs). Funds are locked in immutable smart contracts and released only when the agreed conditions are met, such as delivery confirmation or verified proof of work.

### The RWA settlement layer

OpenHatch is becoming the settlement rail for real-world assets across Messier:

* **P2P RWA Exchange Hub:** OpenHatch escrow will plug directly into the Messier P2P Exchange, so users can settle and exchange physical assets peer to peer.
* **DeepSky:** tokenized real-estate transactions from the first Innovator Hub winner are designed to settle through OpenHatch.
