When you buy from Smallcase and demat is with Zerodha, who holds the stocks?

Basically I bought some smallcases and the demat account was zerodha. Now I sold off my stocks after a while via zerodha, whateve it had. But Smallcase is still showing those cases there. It has been a year since I sold, so I don't remember what was that. My question is what is smallcase showing, are those stocks or some other financial instruments (I mean they say it is a smallcase, might just be on paper or something) IDK. Total stock noob here.
