How it works
- Choose your pair — Select the currency you want to send (From) and the one you want to receive (To).

- Go to the exchanger — Click through to complete your swap on the exchanger’s site.
Why traders use this tool
- Best rate first: We surface the offer with the most favorable effective price and clearly mark it as BEST.
- Transparent math: Displayed numbers use an effective rate that helps you compare offers fairly (we show the inverse form so “bigger is better” on screen).
- Reserve shown: See the liquidity reserve of each exchanger to avoid failed or partial swaps.
- Real-time data: Offers and names are pulled live from trusted sources.
- Clean UX: Names are mapped to human-readable exchanger titles. No guesswork.

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.
