Changelly
Changelly fees are service and network costs best compared through net output
Changelly fees are the service charge for executing a crypto swap plus the network amount deducted for outbound settlement. A direct floating-rate exchange applies a 0.25% service fee to the output, while fixed-rate pricing uses a dynamic fee embedded in the locked quote. Your sending wallet also pays its own blockchain fee. Compare identical asset pairs, networks, input amounts, and rate types, then choose by the final amount delivered to the receiving wallet.
The short version: A 0.25% floating-rate service charge matters less than the payout network deduction on many small swaps.
Net output is the decision number for wallet-to-wallet swaps
Net output from a Changelly swap is the amount expected at the destination address after the quoted deductions. It gives a wallet user one comparable number, even when two services describe their charges differently. Enter the same input quantity on each service. Match the destination asset and network. Then record the final receive amount rather than comparing percentages in isolation.
This method captures service charges, the offered conversion rate, and the outbound network deduction. It also prevents a false comparison between unlike assets. Receiving USDT as an ERC-20 token on Ethereum is operationally different from receiving USDT as a TRC-20 token on Tron. Their ticker is shared, but their settlement systems and fee units are separate.
Which charges leave the sending wallet?
A Changelly crypto swap presents two fee layers: an exchange fee and a payout network fee. The complete wallet budget has three cost effects because the sender also funds the deposit transaction. Changelly receives its exchange charge. The source blockchain's miners or validators receive the pay-in fee. The outbound venue sets the payout network amount used to settle the purchased asset.
The pay-in fee appears inside the sending wallet, not as part of the Changelly receive estimate. Bitcoin wallets calculate it from transaction size and a satoshi-per-virtual-byte rate. Ethereum wallets calculate it from gas used and the fee per gas. Sending the full wallet balance therefore requires special attention: the wallet still needs enough native currency to broadcast the deposit.
The payout network fee works differently. Changelly denominates it in the asset being received and deducts it from the converted output. A BTC-to-ETH order therefore uses ETH for its outbound network deduction, while the sender separately pays the Bitcoin transaction fee in BTC.
Floating-rate Changelly fees use a fixed 0.25%
Changelly charges a 0.25% service fee on the output of a direct floating-rate crypto exchange. That equals 25 basis points, or a decimal multiplier of 0.0025. The percentage stays proportional to the converted amount. API-partner transactions can use another schedule, so the direct-site percentage should not be imposed on an embedded quote.
A unit-free calculation makes the order of deductions clear. Suppose conversion before fees produces 100.000 units of the output asset. The service charge is 100.000 × 0.0025, which equals 0.250 units. That leaves 99.750 units before settlement. If the displayed payout network fee is 0.400 units, the destination receives 99.350 units. The sending wallet's deposit fee remains outside that figure.
Floating describes the exchange rate, not the service percentage. Market movement during execution changes the conversion output. That rate movement should be recorded separately from the 0.25% charge when reviewing the completed order.
Fixed-rate pricing replaces the percentage with a dynamic margin
That said, Changelly fixed-rate pricing embeds a dynamic exchange fee within the locked receive quote. There is no reusable fixed-rate percentage to add afterward. The useful comparison is the guaranteed payout shown for the specified input, less any network deduction that the confirmation screen displays separately.
Timing forms part of that price. A fixed-rate API rate identifier remains usable for 1 minute while the transaction is created. The fixed-rate deposit window is 15 minutes for many assets and 20 minutes for BTC, XMR, LTC, DCR, EOS, GAS, BNB, and VET. A floating-rate deposit address remains available for 3 hours. These addresses are transaction-specific rather than permanent wallet destinations.
The exact input amount matters as much as the deadline. If a wallet subtracts its mining fee from the amount entered, Changelly receives less than the fixed order specifies. The fixed terms no longer match. Configure the wallet so the required deposit reaches the supplied address, with its network fee funded separately.
The payout network fee is deducted after conversion
The Changelly payout network fee reduces the asset sent to the receiving wallet. In the Exchange API, amountTo represents output before that deduction, while networkFee states the amount to subtract. The comparable payout is therefore amountTo minus networkFee.
This deduction is an asset amount rather than the 0.25% service rate. Its value follows the selected output network, the withdrawal policy of the executing venue, and network conditions when the transaction is created. Changelly displays an estimate during order creation, but the final deduction can change when settlement conditions move.
Keep the two network charges separate during review. The wallet's pay-in transaction funds movement into the exchange process. The quoted payout network fee funds movement from the executing venue to the destination. Paying one does not remove the other.
Bitcoin, Ethereum, and Solana settle fees differently
Bitcoin, Ethereum, and Solana use different fee mechanisms, so Changelly quotes for their output assets are not directly interchangeable. Bitcoin records BTC to 8 decimal places, making 1 BTC equal to 100,000,000 satoshis. Wallets quote Bitcoin fee rates in satoshis per virtual byte. More transaction inputs increase virtual size, even when the BTC amount sent stays unchanged.
Ethereum expresses gas prices in gwei, where 1 gwei equals 1,000,000,000 wei. A plain ETH transfer starts with 21,000 gas before contract execution or added data. Under EIP-1559, the fee combines a burned base fee with a validator priority fee. The base fee moves by at most 12.5% per block, which explains why an Ethereum-based payout estimate changes with demand.
Solana charges a base fee of 5,000 lamports per signature and supports an optional prioritization fee. One SOL contains 1,000,000,000 lamports. Half of the base fee is burned, while half goes to the validator; the prioritization fee goes to the validator. Changelly's displayed SOL withdrawal amount still reflects the executing venue's settlement charge rather than promising a raw one-signature network fee.
Token standards add another layer. Tether on Ethereum uses ERC-20, on Tron it uses TRC-20, and on BNB Smart Chain it uses BEP-20. The chosen network determines the destination address rules, required native fee asset, and outbound cost.
Minimum swap amounts magnify flat network deductions
Day to day, Changelly calculates the minimum swap amount separately for each pair and rate type. The threshold must satisfy two conditions: it must cover the payout network fee and meet the executing market's minimum exchangeable lot. A change in either input produces a different minimum, so yesterday's threshold should not be reused for a new order.
Flat asset deductions weigh heavily on small swaps. In a hypothetical quote, a 0.400-unit network fee consumes 4% of a 10-unit output but only 0.4% of a 100-unit output. The service percentage remains proportional in both cases. Increasing order size lowers the relative effect of the flat deduction, although it does not guarantee a better exchange rate.
Ledger Live and API integrations may show another schedule
Broadly, Changelly fees inside Ledger Live or another API integration can differ from the direct exchange schedule. Changelly's terms specifically separate API-partner transactions from the direct 0.25% floating fee. The embedded interface may include a partner charge, so the provider name, fee details, and final receive amount all belong in the comparison.
Equally, Changelly Exchange API v2 uses JSON-RPC 2.0 and exposes fields including fee, networkFee, amountTo, and visibleAmount. That structure lets an integration represent the Changelly charge and a partner extra fee. A wallet interface may combine those values visually, which makes the final payout more dependable than reconstructing the schedule from a direct-site headline.
Fiat transactions sit outside the crypto-to-crypto calculation. Changelly's crypto-to-fiat sell flow starts with a 3.95% fee, while card-purchase charges come from the selected fiat partner. Neither schedule should be substituted for the fee on a wallet-to-wallet crypto swap.
A five-check quote comparison before confirmation
A Changelly quote comparison is valid only when every provider receives the same instructions. Use one short checklist before sending funds:
- Enter the identical input asset and exact quantity on every service.
- Match the output asset and token network, such as USDT on ERC-20.
- Compare floating quotes with floating quotes, or fixed quotes with fixed quotes.
- Record the payout after the displayed network deduction, not the pre-deduction conversion.
- Add the sending wallet's pay-in fee and any clearly identified partner charge.
Refresh all quotes within the same short decision window because rates and settlement costs move independently. Choose only after confirming the destination address, network, minimum amount, and deposit deadline. This process makes Changelly fees comparable with another route without pretending every interface uses the same labels.
Uniswap, 1inch, Coinbase Advanced, or Kraken Pro use other cost models
Uniswap, 1inch, Coinbase Advanced, and Kraken Pro separate costs differently from Changelly. Uniswap v3 routes a swap through liquidity pools with four established fee tiers: 0.01%, 0.05%, 0.30%, and 1%. The user also pays wallet gas, and an ERC-20 approval requires its own Ethereum transaction when a suitable allowance is absent.
1inch aggregates decentralized exchange routes and exposes route-specific gas alongside pool costs. Coinbase Advanced uses an order book with maker and taker pricing tied to trading activity. Kraken Pro also uses maker and taker fees, then applies an asset-specific withdrawal minimum and fee when funds leave the exchange.
Those models suit different operations. An existing exchange balance avoids a new deposit for each trade, while a decentralized route keeps execution connected to the user's wallet. Changelly remains straightforward for one-off cross-asset delivery when its final payout exceeds the alternatives after every required transfer.
Record the quote and reconcile the completed swap
A Changelly fee record should preserve the input amount, asset pair, token network, rate mode, expected payout, network deduction, deposit deadline, and Changelly transaction ID. Save the wallet's pay-in hash as well. After settlement, the payout hash confirms the output transaction and the destination balance confirms the amount actually delivered. The same ground is broken down in Changelly explainer.
Reconcile floating and fixed orders differently. A floating order's final exchange rate moves during processing, while its direct service rate remains 0.25%. A valid fixed order should be checked against the final payout displayed at confirmation. In both cases, compare asset units first; converting everything into fiat afterward introduces another moving price.
Create a fresh quote for every swap. Network conditions, market rates, minimum amounts, and partner schedules change, while old deposit addresses expire. This small maintenance habit keeps the recorded cost tied to the transaction that actually settled.
FAQ
Are larger Changelly swaps charged at a lower percentage?
Direct floating-rate swaps retain the same 0.25% service percentage as the amount grows. The payout network deduction is stated as an amount in the receiving asset, so its relative weight shrinks on a larger output. Fixed-rate and API-partner orders follow their displayed quotes instead. Compare the final receive amount because a larger order can also encounter a different market rate or limit.
How does the selected USDT network change the total fee?
The selected USDT network determines both settlement costs and address compatibility. ERC-20 USDT uses Ethereum and requires ETH for the sending wallet's gas. TRC-20 USDT uses Tron and requires TRX, while BEP-20 USDT uses BNB Smart Chain and requires BNB. Changelly's outbound network deduction also follows the chosen route, so quotes must use the same token standard before their outputs are compared.
Does splitting a swap into several smaller Changelly orders reduce fees?
Splitting an order does not reduce the 0.25% proportional charge on direct floating swaps. It repeats the payout network deduction and creates another pay-in blockchain transaction for every part, which raises the combined settlement cost. Separate orders make sense only when a quoted limit, execution requirement, or deliberate timing plan requires them. Calculate the combined delivered output before dividing the transfer.
Are bank-card purchase costs included in the 0.25% crypto swap fee?
Bank-card purchase costs are separate from Changelly's 0.25% direct floating crypto-exchange fee. Fiat partners set card-processing charges, payment-method costs, limits, and conversion terms for their own offers. The applicable total appears in the selected purchase quote. A crypto-to-crypto percentage should therefore never be used to estimate a card purchase or a bank payout.
Is identity verification charged as an extra Changelly fee?
Identity verification is not presented as a separate Changelly fee line. A transaction selected for verification can remain pending while the requested checks are completed, but that review does not replace the displayed exchange and network charges. The relevant financial effect comes from time and market movement, especially for a floating-rate order, rather than a standard verification percentage.
Will a refund return the original blockchain fees?
Blockchain fees already consumed by confirmed transfers are not reversible. A Changelly refund can also require a new outbound network payment, and certain incorrectly constructed transactions create supplementary processing costs. Those amounts are deducted from the refundable balance with the user's consent. The refund therefore should not be expected to equal the original deposit, even when no exchange was completed.
Does a memo or destination tag increase the quoted fee?
A correctly supplied memo or destination tag does not add a standard fee to the quote. Networks and custodial wallets that use shared addresses rely on that extra identifier to credit the right account. Omitting it prevents automatic allocation and introduces manual handling. Any later processing or refund cost is an exceptional operational charge, not part of the original service percentage.
