Fees and commissions

Where commissions and network fees apply across deposits, invoices, withdrawals, and auto-converting.

Cryptonly applies fees at a few distinct points in the payment flow. Rates can be tenant-specific — always read the actual rate from the API response rather than hardcoding it.

Deposit commission

Every completed deposit — standalone, invoice-linked, or an address-provision child payment — has a commission deducted before the remainder is credited to your balance. The effective rate for your tenant is returned as depositCommission on GET /currencies, and reflects your tenant-specific override when one is configured, otherwise the platform default.

Withdrawal network fee

POST /withdrawal/quote returns a fee breakdown with the real on-chain network fee, in both the network's base currency (feeNative/feeCurrency) and the withdrawal currency. This fee, plus the withdrawal amount, is debited from your balance when the quote is committed — see Withdrawals lifecycle.

Conversions

Conversions (admin panel, or auto-converting on a withdrawal) are not charged a separate commission. Stablecoin-to-stablecoin pairs (e.g. USDT ↔ USDC) convert at 1:1. See Balances, transfers, and conversions.

Where to check exact amounts

  • GET /currenciesdepositCommission, minDepositAmount, minWithdrawalAmount per crypto currency

  • POST /withdrawal/quote response — fee breakdown and totalDeduction for a specific withdrawal

  • Transaction History detail drawer (Accounts → History) — commission and net credited amount for any past deposit
