What is FRAX share?

Excuse me, could you please elaborate on FRAX share? I've heard it mentioned in the cryptocurrency community but I'm not entirely sure what it entails. Is FRAX share a token or a stake in a specific project? How does it function within the broader cryptocurrency ecosystem? Is it used as a stablecoin or does it have a different purpose? Additionally, what are the key features and benefits of FRAX share that make it unique in the market? I'd appreciate a concise yet comprehensive explanation of this concept.
