What is FRAX swap?

Could you kindly elaborate on what FRAX swap exactly entails? I've been hearing about it quite frequently in the cryptocurrency circles, but I'm still a bit hazy on the specifics. Is it a type of trading mechanism? Or does it refer to a particular type of cryptocurrency swap? Would it be accurate to compare it to other swap mechanisms I may be familiar with? Moreover, how does FRAX swap fit into the broader landscape of cryptocurrency finance? I'm eager to understand its role and significance in this rapidly evolving field.
