Can Dex transactions be traced?

Could you please elaborate on the traceability of transactions conducted on decentralized exchanges, or DEXs? Are there any inherent features in these platforms that make it difficult, if not impossible, for regulators or other interested parties to trace the origin, destination, or details of these transactions? Furthermore, are there any specific privacy-enhancing technologies employed by DEXs that further obscure the visibility of these transactions, and what are the implications of such measures for both users and the broader cryptocurrency ecosystem?
