Simpleswapcrypto exchange rates lock fixed quotes temporarily while floating payouts follow market prices during processing
Simpleswapcrypto exchange rates offer a time-limited fixed quote or a floating estimate of the receiving amount. The fixed option requires timely deposit confirmation, while floating pricing applies when processing occurs. Compare the selected networks, deposit amount, and quoted output alongside the rate type.
Rate choice for the selected exchange direction
Available exchange directions determine whether a quote fits the selected assets, networks, deposit amount, and rate mode. Currency support alone does not establish that every conversion is available. The recipient address must accept the exact asset and network used for payout. A favorable estimate cannot resolve an incompatible destination.
The payout transaction and receiving wallet establish delivery; a deposit confirmation only records progress on the sending side.
Deposit timing for fixed quotes
Fixed pricing protects the quoted rate for 20 minutes when the deposit satisfies the confirmation requirement. The quote window governs deposit qualification, and subsequent processing or wallet delivery can extend beyond it.
Deposit arrival and confirmation
The deposit must arrive and receive at least one blockchain confirmation within the lock window. Sending before expiry alone does not satisfy that condition.
The sending wallet or withdrawal service and the blockchain both affect the time available. A queued withdrawal has not yet supplied a confirmed deposit. Network congestion can delay confirmation after broadcast, so the remaining quote time must cover more than submitting the transfer.
Deposits after expiry
A late deposit does not automatically receive a new rate in every case. If the originally estimated fixed rate remains unchanged, the fixed-rate terms allow processing at that rate. If it has changed, the exchange may fail, with a refund or execution at a new fixed rate offered.
Those alternatives depend on the actual exchange state. A later calculator quote does not establish that an existing deposited exchange has accepted a revised rate.
What changes a floating payout?
Floating payouts use the market rate available when the exchange processes, so the final receiving amount can exceed or fall below the initial estimate. Waiting for blockchain confirmations creates time between quote creation and execution. Prices and available liquidity can change during that interval.
Price changes on either side of the pair matter because the quote expresses one asset in units of another. A less liquid direction can also produce a different available conversion price. Floating pricing leaves the final amount open to execution conditions; a higher opening estimate is not a locked entitlement.
Amount limits and unchanged exchange details
The selected pair and rate type determine the permitted deposit amount. Minimum amounts reflect the economics of the conversion, including network costs and liquidity. Sending below the displayed minimum can prevent processing. An amount that works for a floating quote does not automatically satisfy the limits of a fixed quote. Send the amount specified in the order. You cannot change the order yourself while its status is Confirming, Exchanging, or Sending. An insufficient or excess deposit can lead to cancellation, with a refund offer conditional on the transferred amount exceeding the network fee.
The application programming interface (API) returns current amount ranges for the selected pair and rate type. A null bound alone does not confirm that an amount is permitted. Use the API's exchange check to assess whether an exchange can be created with the selected parameters. Range values can change, so an older response cannot establish the permitted amount indefinitely. Floating exchanges have no strict time or upper amount restriction, although liquidity and transaction checks still affect execution.
Pricing within the receiving amount
The crypto swap quote incorporates dynamic pricing costs into the receiving amount, while the sending wallet may charge a separate transfer fee.
Costs within the quote
The service presents an all-in rate, with its trading cost incorporated into the conversion. Pair selection, market volatility, available liquidity, network costs, and routing costs affect pricing. The quoted receiving amount describes what the conversion expects to deliver under its rate conditions. It does not isolate every component of the conversion's total cost.
The initial wallet transfer
For fixed-rate swaps, the displayed payout already includes the network fee for sending the exchanged asset to the recipient. Your wallet's fee for the initial deposit remains separate. That sending fee belongs in the total spending comparison. Deducting the included payout fee again would count the same cost twice.
Quote modes and amount direction
The API supports fixed and floating crypto exchanges. A standard estimate starts with a sending amount; a reverse estimate calculates the input for a desired receiving amount. These choices control different parts of the quote. Amount direction chooses which quantity starts the calculation, and rate type governs exposure to execution-time price changes.
| Quote option | Amount supplied | Conditions on the final amount |
|---|---|---|
| Floating, send amount specified | Sending asset amount | Final output follows execution pricing. |
| Fixed, send amount specified | Sending asset amount | Quote protection requires timely deposit arrival and confirmation. |
| Floating, receive amount specified | Desired receiving asset amount | The output target sets the estimate; settlement can change. |
| Fixed, receive amount specified | Desired receiving asset amount | The matching fixed quote and timely deposit confirmation govern output. |
| Fiat-to-crypto purchase | Fiat purchase amount | The selected payment provider governs the offer and payment checks. |
| Crypto-to-fiat sale | Crypto sale amount | Sale availability and payout terms govern fiat proceeds. |
| An output target sets the calculation direction; it does not override the rate type or provider conditions. | ||
The public API guide sets rateId to null in its floating-rate creation example. That example does not establish whether fixed-rate creation requires a matching quote identifier. A reverse estimate calculates the input needed for a chosen output target; availability still rests on the selected pair and its current limits.
Quotes compared on matching inputs
Comparable quotes use the same sending amount, asset direction, networks, and rate type, because changing those inputs changes the offer. Quotes taken at different moments also face different market and liquidity conditions. Dividing quoted receiving units by deposit units gives an effective quoted rate in receiving units per sending unit. That ratio describes the displayed conversion. It does not establish an independently tradable market price or reveal the exact service fee. Wallet transfer costs remain separate unless the comparison explicitly includes them.
An earlier fixed quote and a fresh floating estimate express different commitments. Their receiving amounts need the accompanying timing and deposit conditions.
Changing the deposit amount before sending funds calls for a fresh estimate. Pricing and available liquidity can affect the output for the new amount.
Account and partner pricing differences
Account benefits and partner commissions can change a quote even when the asset pair stays the same. Eligible Loyalty Program discounts reduce the service-fee component within the rate. Cashback follows its own reward conditions, so an accrued reward remains separate from the amount quoted for delivery. A rate comparison needs the account's active reward setting.
Partner integrations can apply their own configured commission to crypto-to-crypto exchanges. The API supports commission settings by key and pair, with a transaction-specific setting available at exchange creation. That makes the surrounding exchange interface relevant to pricing. Two interfaces using the same underlying service need not present identical receiving amounts, even before market timing changes.
Fiat offers outside crypto rate locks
Fiat offers use the selected payment arrangement, so a crypto swap's fixed-rate window does not automatically apply to a purchase or sale. Purchases depend on provider, payment method, region, and verification requirements. Supported sales quote fiat proceeds under their own availability and payout conditions. Comparing these offers requires preserving the payment currency and the actual receiving currency. A crypto receiving amount and a fiat payout measure different outcomes.
Rate records and confirmed wallet delivery
Exchange records give the currencies, amounts, and current status for the swap identified by its Exchange ID. Reconciliation uses that exchange's quote and payout details. A later calculator refresh describes a separate pricing moment.
Confirming means the deposit is awaiting the required blockchain confirmations. Exchanging describes conversion, and Sending describes dispatch toward the recipient. A deposit hash or an exchange-creation response therefore cannot establish the amount that reached the receiving wallet.
If the exchange is Failed, Expired, or Verifying, contact support before sending more funds. Support can investigate that state using the Exchange ID and transaction details. A significant floating-rate discrepancy may lead to a pause, with approval sought for the revised rate or a refund offered. Those options depend on the particular exchange.
The service identifies a completed exchange with the status Finished.
Frequently asked questions about Simpleswapcrypto exchange rates
Can a fixed quote guarantee the later cash value of the received crypto?
A fixed crypto quote does not guarantee the later cash value of the received asset. Its protection concerns the quoted crypto conversion under the deposit and confirmation conditions. Any later sale uses that sale's own market rate, fees, and payout arrangements.
Is a reverse estimate the same as swapping the pair in the opposite direction?
A reverse estimate changes which amount drives the calculation, while the sending and receiving assets keep their selected roles. It asks how much input is needed for a chosen output target. Swapping the pair direction exchanges those roles and creates a different conversion request.
What does v3 API error 422 mean when requesting an exchange quote?
In the v3 API, error 422 means the requested amount is outside the permitted range. The valid limits belong to the selected currencies, networks, and rate mode. Retrieve the corresponding ranges before changing the amount. A pair-not-found response identifies a different issue, so an out-of-range amount does not establish that the entire exchange direction is unavailable.
Can I reuse a Simpleswapcrypto deposit address to recover an earlier quote?
A deposit address belongs to one specific exchange and must not be reused for another transaction. A fresh exchange must use its own deposit instructions. Sending again to an old address does not recreate the earlier rate conditions, and recovery of a repeated deposit is not guaranteed.
How can I share a rate discrepancy without exposing private exchange details?
Share the Exchange ID and relevant transaction details privately with the service's support team. The Exchange ID allows the team to identify the affected swap. Publishing it can expose exchange information to people using fake support messages or social engineering. A public description can discuss the rate issue without including the identifier or private account details.
