Fee Overview
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.
Payin Fees
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.Exchange Rate Conversion
Payin supports two modes:- 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)
Payout Fees
When merchants initiate on-chain payments to end users’ wallet addresses from their NUSD balance, the fee can be borne in two modes:App-Pays Mode (Merchant Pays)
User-Pays Mode (End User Pays)
Payout Exchange Rate Conversion
During Payout, NUSD needs to be converted to the on-chain token (USDT/USDC). The system performs the conversion at the real-time exchange rate.Settlement Fees
