Fixed vs floating crypto exchange rates
Reviewed September 13, 2026 · Orbiswap editorial
SHORT ANSWER
A floating quote estimates the payout and can change before conversion. A fixed quote, when available, protects the stated rate subject to its deadline, deposit instructions and exchange conditions. Neither label alone promises an instant payout or removes the need to check the receiving network.
01
Floating rates leave the output open to market movement
The initial amount is an estimate, not a completed conversion. Time between requesting the quote, sending the deposit and reaching the required confirmations can expose the exchange to different market conditions. The eventual payout can be above or below the first figure.
02
Fixed rates protect a quote under stated conditions
Quote expiry determines whether an order can still be created; it is not, by itself, the deposit deadline. After creating an order, follow that order's payment instructions. A refreshed quote does not extend an existing deposit window. Late or incorrect deposits and other exchange exceptions can affect the outcome; a fixed label is not an unconditional completion guarantee.
03
Assess the quoted rate and payment conditions
Read the rate type attached to the current quote. Review its output, payment conditions and the sending wallet's readiness. A fixed quote can make the expected outcome more predictable within its conditions, while a floating quote leaves it exposed to execution-time movement. Neither is always the cheaper option.
- Check quote expiry before opening the wallet send screen
- Include the network confirmation time in the decision
- Never assume every pair supports both rate types
CONCRETE EXAMPLE
Example: reading the rate attached to an ETH-to-USDT quote
For an ETH-to-USDT quote, check the ETH amount and both networks, then read the rate type attached to that quote and the displayed USDT output. A floating figure is an estimate; a fixed figure remains subject to its payment conditions. The quote's expiry countdown limits order creation and is not itself a deposit deadline. This example explains how to read a quote; it is not a live price.
CHECK THIS CASE
- 1Compare the outputs for the same assets, networks, amount and quote time.
- 2Distinguish quote expiry from the deposit window, and read the exact payment instructions for the order.
- 3Refresh an expired quote before creating an order. Once the order exists, follow its payment instructions; if funds were already broadcast, track that order instead of making another payment.
ACTION CHECKLIST
Before you continue
- Confirm whether the quote says fixed or floating.
- Check the expiry countdown.
- Send the exact amount when fixed conditions require it.
- Compare the final estimated output.
- Refresh an expired quote before creating an order. After order creation, follow its payment instructions; after broadcast, retain that order and check its status.
FAQ
Questions about this topic
Does fixed mean the quote never expires?+
No. Quote expiry limits order creation and is distinct from the deposit window. Once the order exists, follow its payment instructions. If a payment has already been broadcast, check that order rather than sending a replacement deposit.
Can a floating output be lower or higher?+
Yes. Execution conditions can move in either direction between the estimate and conversion.
Which rate is cheaper?+
There is no permanent answer. Compare the live estimated amount received and the conditions for the specific route.
