A clear exchange quote should show:
| Field | What it tells you |
|---|
| You exchange | Asset or fiat currency and amount deducted |
| You receive | Estimated asset or fiat currency and amount credited |
| Exchange rate | Rate used to calculate the result |
| Applicable costs | Fee, spread or other cost shown for the operation |
| Quote validity | Whether the quote can still be confirmed, if applicable |
| Provider | Entity providing the exchange service for the account |
Do not confirm an exchange if the currencies, assets or expected amounts are unclear.
What is the difference between a rate, fee and spread?
Exchange rate is the conversion relationship between the two assets or currencies.
Fee is a separately identified cost charged for the operation, if applicable.
Spread or markup is a difference that can be incorporated into the quoted rate rather than shown as a separate line.
Network cost relates to an external blockchain transfer and is not the same as an exchange cost.
The final quote must make the total expected result understandable even when not every pricing component is presented in the same format.
Can the rate change?
Yes. Crypto markets can move quickly. A rate shown before the confirmation screen, in a public market widget or in an old screenshot may no longer apply when you submit the exchange.
The rate that matters is the current executable quote shown in Quppy at the point of confirmation, subject to any quote-validity rule displayed there.
Quppy must not use claims such as “guaranteed rate,” “rate locked,” “best rate” or “the rate you see is always the rate you get” unless the product mechanics and evidence support them.
Are crypto exchanges free?
This article does not state that crypto exchange is free.
Quppy currently has a separate commercial claim for supported EUR and GBP fiat transfers: no Quppy transfer fee. That statement does not automatically cover:
- fiat-to-crypto exchange;
- crypto-to-fiat exchange;
- crypto-to-crypto exchange;
- blockchain-network costs;
- third-party costs.
Review the current quote and applicable terms before confirming.
When does a network cost apply?
A blockchain network cost can apply when crypto is sent to an external wallet or received through a transaction whose sending platform charges a network fee.
It is separate from the exchange quote unless the app explicitly combines or discloses it as part of the same transaction.
Network costs can change with the blockchain, congestion and provider policy. Quppy does not publish one fixed network fee for all assets and networks.
A public website rate, if shown, should normally be treated as indicative unless the page explicitly states that it is executable and describes its validity.
An indicative widget can help compare pairs but should not be used to promise:
- a guaranteed result;
- zero spread;
- a locked rate;
- the final amount received;
- availability of a pair for every user.
The final exchange decision must be based on the in-product quote.
Why can the amount received differ from a market-price website?
Differences can result from:
- market movement;
- bid/ask spread;
- liquidity and execution route;
- size of the transaction;
- provider pricing;
- exchange or service cost;
- rounding;
- regional pair availability;
- quote timing.
A public market index does not necessarily represent an executable price for a specific customer and amount.
What if the final result looks wrong?
Before confirmation, stop and review the pair, direction, amount and quote.
After confirmation:
- preserve the transaction reference;
- record the quoted and completed amounts;
- take a screenshot if available;
- check whether the transaction is complete or pending;
- contact Quppy Support if the result does not match the confirmed details.
Do not repeat the exchange while the first operation is unresolved.
