What is the Seneam fee?

Excuse me, could you please elaborate on the Seneam fee? I'm a bit unclear on what it encompasses and how it impacts transactions or usage within the Seneam ecosystem. Could you provide some context on how it's calculated, if there are any variable factors that come into play, and perhaps give an example scenario where this fee might be incurred? Additionally, is there any transparency or predictability in the fee structure that users can rely on? Thank you for your time and consideration.
