Swapuz and Exolix are two different services. First, it was said that exolix was related to changelly/the change, now you say they were over estimating rates.
Do you have any relationship with Quickex? You seem to be shilling it a lot in this thread, and on top of that, spreading misinformation about other services.
For those who are privacy concerned, Trocador only validates to use Exolix or WizardSwap. Quickex has a KYC rating of C (meaning more likely to freeze due to KYC) and requires your IP to be logged with Trocador if you use it, while Exolix does not require IP logging and has a KYC rating of B (meaning less likely to freeze for KYC than Quickex).
Based on Trocador's assessment alone, Exolix seems to be a more privacy friendly and safer option than Quickex.
I just share information I found about Swapuz and Exolix. Of course, they're distinct services, and my intention wasn't to blur the lines there.
I don't work for Quickex, but I've had positive experiences using them, and wanted to highlight them as an option for rate checking (as you mentioned getting different rates). I will clarify my posts in the future to not appear as if promoting one service over another. I just wanted to give context as to why you may see higher/lower rates across certain aggregators and swaps.
It seems that regardless of the security rating, if you make an exchange through Trocador, the IP address will be saved. Again, nothing prevents you from using a proxy.
