Not sure at this point i was scammed

Ok i did some checkings first, but i do not know where i stand and what are the risks now.

Note that for now i haven't lost any money. In short - i was approached by an nft reseller for my artwork. - after some discussion, they agreed to pay all gas and plaform fees, and i now stand on that platform with 4.6 wETH (roughly 17k usd). - i haven't given any personal info nor wallet details from my other wallet. - there is nothing that could trace me back given what the person already knew already from my online public info.

Questions: - is the fact i directly messaged this person through telegram a problem? What could thd risk be? - i'll trybto retrieve these wETH for real money later, i know it can be a tedious process. Again i paid nothing at all, they funded the initial eth for minting. I didnt do anything.

Should i stop everything now if there is a risk? What could be the risk given the exact situation i'm in?
