For the Defi protocols like AAVE, I think Compound is another, if you lend your crypto for interest, are you going to get back the same crypto when you withdraw it, or otherwise will fungibility be an issue?

Eg if someone has dirty coins and they get them into these platforms, am I at risk for getting some of them when I withdraw the coins I put in to try to get interest?

Same thing if I use one of them to take a loan, and then try to deposit it in a centralized exchange, is there a risk it could be blocked?
