A quote can look clear until the market moves while your crypto swap is being processed. For a fixed vs floating rate crypto swap, choose Fixed when the recipient must get the displayed amount despite a market-rate change. Choose Floating when a higher or lower final amount is acceptable. The checks below help you compare both modes on equal terms, verify every transfer detail, and create the order without relying on another exchange’s timer or fee claims.
Summary: Fixed locks the rate when a YBEX order is created, so later market-rate movement does not change the final receive amount. Floating follows current market conditions until completion, so the result can rise or fall. Compare both modes with the same amount, pair, and networks, then verify the address and order conditions before sending.
The choice is about certainty, not a prediction of where the market will go. On the YBEX swap widget, “You send” is what leaves your wallet and “You receive” is the destination asset shown for the selected mode. The source network carries your deposit; the destination network carries the payout. Keep those settings unchanged while comparing rates, or the comparison stops being useful.
Define the result you need before choosing a rate
Ask whether the recipient must receive a specific amount of the destination coin. An invoice or wallet balance target may leave no room for a smaller payout. In that case, Fixed matches the need for certainty about market-rate movement.
If an exact payout is not required, decide whether you can accept a result above or below the first number shown. Floating keeps the receive amount linked to current market conditions until completion. It does not promise favorable movement.
Decision rule: Choose Fixed for an exact market-rate outcome. Consider Floating only when a changing final amount is acceptable in both directions.
Compare Fixed vs Floating with the same settings
Do not compare one mode using USDT on one network with the other mode using a different network or amount. Set the same send amount, source asset, destination asset, source network, and destination network. Switch the rate mode close together in time, then compare the current “You receive” values.
| Decision point | Fixed | Floating |
|---|---|---|
| Rate behavior | Locked when the order is created | May change until the order is completed |
| Receive amount | Not changed by later market-rate movement | Updates with current market conditions |
| Best fit | The recipient needs the displayed amount | A higher or lower final amount is acceptable |
| Main uncertainty removed | Market-rate movement after creation | None; market movement remains part of the outcome |
| What it does not fix | Wrong address, wrong network, wrong amount, or delays | Wrong address, wrong network, wrong amount, or delays |
Look at expected output, not a single fee label. In YBEX API terminology, rateMode controls Fixed or Floating rate behavior, while feeMode controls how a fee is treated. They are separate settings. YBEX does not publish a universal rule that Floating is always cheaper or that Fixed always adds a particular percentage.
Follow these eight steps before you tap Exchange
- Write down whether the recipient needs an exact amount of the destination asset or can accept a changing result.
- Set the real send amount, crypto pair, source network, and destination network in the YBEX widget.
- View Fixed and Floating close together in time without changing those four comparison settings.
- Compare the displayed receive amounts and read the current notices or deposit conditions on the screen.
- Select Fixed for certainty against later market-rate movement, or Floating for a market-linked result that may rise or fall.
- Check the recipient address character by character, then add the required memo or tag if the receiving service supplied one.
- Confirm both networks, the send amount, the chosen rate mode, and that the funds are ready before creating the order.
- Create the order, follow only its current payment instructions, send once, and save the Order ID with the original details.
Workflow:
Exact payout required? → keep amount, pair, and networks identical → compare both modes now → read current conditions → choose Fixed certainty or Floating market exposure → verify address, network, and memo → create and pay → save the Order ID
Prepare the sending wallet first. Once the order exists, follow that page instead of an old screenshot, a blog example, or another exchange’s timer.
Choose Fixed when the displayed payout must not move with the market
The YBEX Orders API v2 documentation says that FIXED locks the rate at order creation. A later difference in the market rate does not change the final received amount. In plain language, you take a snapshot of the rate for that order instead of letting the payout follow the market until completion.
Use Fixed when receiving less because of market movement would cause a problem. It does not fix a wrong address, make networks interchangeable, or remove technical and compliance delays. Public YBEX documentation also gives no universal late-send timer, so follow the conditions on the live order.
Choose Floating only when movement in either direction is acceptable
FLOATING may change until order completion according to current market conditions. The first receive amount is therefore an estimate, not an exact payout promise. If the market changes, the final amount can be higher or lower than the number you saw before sending.
Floating can fit a swap where a precise destination amount is unimportant and you deliberately accept that uncertainty. Do not choose it because someone says it is always cheaper. Compare the live outputs under identical settings and judge whether the possible change matters to your purpose.
Read the current order conditions instead of assuming a timer or fee
The YBEX Terms of Use describe platform rates as indicative and able to vary in real time, so refresh the comparison before creating an order. For a created Fixed order, the more specific API rule applies: later market-rate movement does not alter the final receive amount.
Processing time and rate behavior are separate. Networks, technical issues, and compliance checks may affect completion. A general processing range is not a Fixed-rate lock timer, and rate mode is not a promise of speed.
If the order page shows a warning or another option, follow that page. Public documentation does not promise a universal retail switch, cancellation, or refund action for every order.
Check address, network, memo, and amount before sending
A rate choice cannot rescue incorrect transfer details. Match the wallet’s source network to the order’s deposit network, and match the destination network to what the receiving wallet supports. A token name alone is not enough because the same token can use different transaction networks.
- Confirm the send asset and exact deposit amount shown by the created order.
- Confirm the receive asset and destination network with the recipient.
- Paste the destination address, then compare its beginning and ending characters.
- Add a memo or destination tag when the receiving wallet requires that extra routing note.
- Verify that the selected rate mode still matches your exact-payout decision.
- Check that the sending wallet has enough balance to make the requested transfer.
The Terms place responsibility for accurate details on the user. Do not use an address from an old order. Any pair example can illustrate the workflow, but your new order always takes priority.
Save the order details and act on the live status
Save the Order ID, rate mode, amount, pair, networks, and address. Send only to that order’s deposit address, do not create a replacement after funds leave your wallet, and follow the live status.
If an instruction does not match, pause and contact official YBEX support with the Order ID. When every check matches, create the swap through the YBEX widget.
Frequently asked questions
Does a fixed rate stay fixed if I send late?
Do not rely on another exchange’s timer. YBEX defines FIXED as locked at order creation, but publishes no universal late-send rule. Read your live order conditions and send only when ready.
Is a floating rate always cheaper than a fixed rate?
No universal YBEX rule says so. Compare the current outputs with the same amount, pair, and networks, then decide whether a changing final amount is acceptable.
Can I switch from Fixed to Floating after creating an order?
Do not assume you can switch freely. Rate mode belongs to the created order, and public retail documentation promises no switch in every case. Follow the live page or ask support.
Can Fixed protect me from a wrong address or network?
No. Fixed addresses market-rate movement, not incorrect details. Before sending, recheck the address, both networks, deposit amount, and required memo or tag.
Why did a Floating swap deliver a different amount from the first quote?
Floating follows market conditions until completion, so the receive amount can move either way. Compare the result with the order details and use the saved Order ID for support.
Does choosing Fixed make the swap complete faster?
No speed promise follows from rate mode. Network confirmations, technical conditions, and compliance checks affect completion separately. Track the live order and act on its status.
