What is a full money swap?

Excuse me, could you please explain what exactly is meant by a "full money swap"? I'm a bit unclear on the concept and how it operates within the realm of cryptocurrency and finance. Is it a type of transaction where two parties exchange different currencies or assets of equal value? How does it differ from other forms of exchange, and what are the potential benefits and risks associated with engaging in a full money swap? I'd appreciate any clarification you could provide.
