I wonder how crypto exchanges can guarantee non-hypothecation of customer funds in a DeFi trustless manner. The methods I've heard about still are tradfi-style centralized mechanisms that can still be subverted, and do not leverage crypto currency's strengths, though I'd sure like to be pointed to any exchange that has really figured this aspect out.

But as a counterpoint, if they couldn't create AML controls for their exchange, they shouldn't have existed -- at least not until they built it.

(to elaborate: Look here, we have 2 billion in this account on Monday, 2 billion on that account on Tuesday and 2 billion over there on Wednesday, so that makes 6 billion total, right?).
