Notes

Fee changes take effect immediately and affect fee calculations for all subsequent transactions. Double-check the numbers before saving.
Withdrawal limits (minimum / maximum) set incorrectly may prevent users from withdrawing. Make sure the limits are reasonable.
Fees are entered as percentages but stored as decimals. For example, entering 1 means 1% and is stored as 0.01.
The “Rate conversion” toggle determines whether USDC/USDT is converted to NUSD at the live rate during deposits and withdrawals. If disabled, it is calculated 1:1.
