What do we call tava in English?

Excuse me, but I'm curious about something. Could you please clarify for me what the English equivalent of "tava" is? I've come across this term in my research but I'm having trouble finding a precise translation. It seems to be a specific concept related to either cryptocurrency or finance, but I'm not entirely sure. Could you shed some light on this for me? I'd greatly appreciate your help in understanding this terminology.
