A fixed-rate exchange request locks the displayed service quote for a defined payment window so the expected receive amount does not move every second while payment is being sent.
Public crypto markets move continuously. A fixed payment window gives the customer time to copy the payment address, send the correct asset and wait for the transaction to reach the network without recalculating the request every few seconds.
The final quote can reflect market movement protection, available liquidity, expected network costs, monitoring, payout processing and operational risk during the payment window.
Confirm the asset, network, exact send amount, sender wallet and recipient wallet before sending. The request screen is the authoritative source for the fixed quote and timer.
