What a Swap Service Can and Cannot See About Your Trade

It is worth knowing exactly what a swap service observes when you use it — not the marketing version, but the honest inventory. That knowledge lets you judge the "no-logs" claim sensibly and shrink your own footprint regardless of what any service promises.
