Four scenarios the gateway is configured for without custom work
Many addresses and high operation frequency. Your own nodes, sweep thresholds to cold storage, sender scoring before funds are credited.
Recurring charges priced in fiat: the amount is computed at a locked rate and the address is tied to the subscription ID.
Invoice in EUR or USD, settle in USDT, with sequential numbering and amount reconciliation within tolerance. The owner is notified on credit.
Client deposits and bulk payouts. Allow-lists for withdrawal addresses and a second factor on every send.
