One thing worth knowing about cross-chain swaps and chain analysis: the timing correlation between the two legs of a swap is the primary deanonymization vector, not the swap mechanism itself. When both sides settle within a tight window, clustering algorithms can match them with surprisingly high accuracy just from block timestamps alone.
Atomic swaps with longer HTLC timelocks (24 hours or more) make that correlation dramatically harder. The longer the window between when each leg confirms, the more noise enters the timing signal. Most people fixate on which service they use when the actual privacy variable is how long they wait between steps.
The other underappreciated angle: UTXO consolidation patterns after the swap. If you swap into BTC and immediately combine outputs into a single spend, you just reconnected what the swap separated. Letting UTXOs age separately before spending them does more for privacy than the fanciest mixing protocol.
Good to see no-KYC options still holding up though. The on-ramp problem is where most privacy actually breaks down in practice.
