Are SFP brand specific?

Excuse me, could you elaborate on the nature of SFP tokens? Specifically, are they branded or specific to a certain platform, protocol, or ecosystem? I've heard various opinions on the topic, but I'm still unclear on whether they maintain a unique identity that is tied to a specific entity. Understanding this distinction is crucial for investors and users alike, as it determines the token's liquidity, use cases, and overall value proposition. Could you clarify this matter for me?
