What is the difference between FixRate and FloatingRate?

FloatingRate follows the market price at the exact moment the swap executes; it's usually the faster option and works well when you are not worried about short-term rate movement. FixRate locks the exchange rate for a short window (typically a few minutes) the moment the swap is created, so the amount you receive is guaranteed even if the market moves — this is ideal for larger amounts. The trade-off: if the sending network is slow and the lock expires, the swap may execute at a new rate or be refunded.

ChangeNOW advertises a 0% commission on crypto-to-crypto swaps and shows the exact "You get" amount before you send anything, so there are no surprise deductions at the end. The actual cost sits in the network fee you pay to move the coins and in the spread of the quoted rate, which depends on liquidity partners at the moment of the swap.

FixRate mode locks the quoted rate for the duration of the swap, which is the recommended choice for large amounts or volatile market conditions. FloatingRate adjusts to the live market rate and usually lands slightly better when the market is calm, but the amount you receive can differ from the estimate if the price moves mid-swap.

Bottom line

FloatingRate follows the market price at the exact moment the swap executes; it's usually the faster option and works well when you are not worried about short-term rate movement. For the full picture, see the complete ChangeNOW FAQ covering fees, KYC, limits, refunds, supported coins, and more.
