The NUSDpay platform charges a standard fee of 1% in total across the Payin and Payout stages. This document describes the fee model and calculation method for each business stage.

​
Fee Overview

The rates above are the platform’s standard rates, with Payin and Payout totaling 1%. For individual merchants with special arrangements, the rates specified in the contractual agreement prevail. You can view the fee configuration currently in effect for your project 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)
Whether exchange rate conversion is enabled is configured independently per token and can be viewed in Fee Station.

​
Payout Fees

When merchants initiate on-chain payments to end users’ wallet addresses from their NUSD balance, the platform charges a fee as a percentage of the payment amount, at a standard rate of 0.2%. The fee can be borne in either of 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

When the merchant settles NUSD into USD fiat currency:

​
Limit Rules

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.

​
Gas Fee

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.

​
