FAQs
Where do the rates come from?
From reputable exchangers and an industry-standard rate source. We compare in real time and show you the most competitive offer first.
What does “reserve” mean?
It’s the exchanger’s available liquidity for the selected pair. A higher reserve generally means your swap can be fulfilled immediately.
Why does the UI show an “inverse” rate?
To make comparisons intuitive. We display an effective, normalized number so higher values mean a better deal for you, while we still rank based on the underlying best rate.
Do you charge any extra fees?
No. You complete the transaction on the exchanger’s website. Always review the final amount and fees on that checkout page.
Is KYC required?
Requirements vary by exchanger and pair. Please check the exchanger’s policy during checkout.
