Processing fee

When your customer fulfills a payment request and you receive the funds, a processing fee will be subtracted from your account. The fee is the same as a deposit fee for the same amount. Just like for a deposit, the fee may depend on the currency and on whether the payment involved a conversion between different currencies. Each fee has a minimum amount that will be subtracted regardless of the transaction amount. The fees are listed on the Fees tab in your merchant dashboard, under the Deposit operations section. The applicable fees are:
  • Deposit crypto
  • Deposit crypto exchange to crypto
  • Deposit crypto exchange to fiat

​
Passing the processing fee to your customer

By default, the processing fee is covered by the merchant. If you prefer, you can pass this fee on to your customer. In this case, after the customer selects the payment currency, CryptoProcessing adds the corresponding processing fee to the total payment amount which the customer needs to pay. To enable this, check the Customer pays the processing fee option when creating a payment request via the dashboard or use the user_fee_percent parameter when creating it via the API. This parameter does not affect the transfer fee which may be subtracted for ETH payments.

​
Transfer fee for Ethereum

When receiving ETH funds or ERC-20 tokens, a transfer fee is subtracted from the merchant’s balance, in addition to the processing fee. The transfer fee covers the cost of gas in the Ethereum network. The transfer fee amount depends on the current gas price when the payment is being processed. It is subtracted in the same currency as the payment itself: for example, the transfer fee for a USDC payment will be in USDC. Unlike the processing fee, the transfer fee cannot be paid by the customer. You can see this fee as Fee transfer in a payment request’s details panel.

​
Refund fee

If an automatic or manual refund is initiated, a fixed refund fee will be subtracted from its amount. The customer will be shown both the fee amount and the result amount they receive when they fill in the refund form. The fee may depend on the currency in which the refund will be sent, which is the same currency the customer paid. If the refund itself is smaller than the fee, the customer will not be able to receive it.
