Assuming you are looking for monetary privateness from different community members, sure most likely. Else it relies on what sort of info entry your hypothetical adversary has.
I am not acquainted with any of the three companies. Cursory search appears to point that they’re centrally operated, however some are known as “non-custodial”. It isn’t apparent to me, what mentioned function is meant to ivolve precisely or how it’s applied, however I did not attempt too laborious to seek out out.
I didn’t see any indication or guarantees that the companies don’t maintain logs. In reality, since a few of these companies promote their nice buyer assist, I’d count on them to maintain complete logs so as to have the ability to reply to buyer assist requests. Clearly, no one however the staff (or perhaps even only a subset of them) can let you know what the precise inside information retention practices of those companies are.
That being mentioned, buying and selling to a different coin will disintermediate your transaction historical past to all however the change that facilitated the commerce (“swap change”). Relying on how the swap change receives the deposits or facilitates the commerce, the service that you simply initially bought from (“unique change”) wouldn’t essentially know who you despatched to, however particularly would have nearly no likelihood to attach it to the later fee that despatched you the opposite forex, besides maybe by the quantities transferred and the timing or through mixed info from unique and swap change.
There are nonetheless information of:
- your unique buy on the unique change together with your full buyer data
- the onchain document of the switch(s) connecting the unique change and the swap change
- the document on the swap change the place you hopped chains
- the onchain document of the withdrawal from the swap change
- pockets fingerprints, transactions you made, and so forth. that is perhaps linked by a sufficiently motivated sleuth
So, it does enhance your privateness from different community members normally, however relying on what your risk mannequin is, an adversary would possibly a) simply ask clients of the unique change what they did after buying there, and usually assume that you simply nonetheless personal the cash except you present info that convinces them in any other case, or b) assuming that your purported adversary has entry to the logs of each companies merely be capable to comply with the trail utterly.
