The above fees are configured independently per project; different projects may have different fee schemes. The specific fees are subject to the contractual agreement. You can view the current project’s fee configuration in the admin console Fee Station or via the Query Platform Fees API.
When an end user pays to the merchant’s deposit address, NUSDpay charges a fee based on the deposit amount, which is deducted before crediting to the merchant wallet in NUSD.
Actual credited to merchant (NUSD) = Deposit amount × (1 - Payin fee rate) × Exchange rate

Exchange rate
Real-time exchange rate of deposit token → NUSD (if exchange rate conversion is configured)
No exchange rate conversion: Deposit tokens are credited directly as NUSD at 1:1 (applicable to NUSD token deposits)
With exchange rate conversion: Deposit tokens are credited as NUSD after being converted at the real-time market exchange rate (applicable to USDT/USDC deposits)
Whether exchange rate conversion is enabled is configured independently per token and can be viewed in Fee Station.
Payout requests below the minimum withdrawal amount or above the maximum withdrawal amount will be rejected. The specific limits can be viewed in Fee Station.
The gas fee for on-chain transactions is advanced by the NUSDpay platform and is already included in the service fee rate, so merchants do not need to be concerned about it separately.
