Glossary
Key terms used throughout the Niftipay merchant guide.
Terms & Definitions
Rolling reserve
A percentage of card-native volume held for a fixed period (10% for 181 days) and released daily as it matures, to cover potential chargebacks.
Settlement
The transfer of confirmed funds to you, paid in EUR or USDT on a T+9 business-day cycle.
Payout
The card/fiat settlement cycle (T+9), with a €100 minimum that accumulates across cycles until it is cleared — distinct from a crypto withdrawal.
Withdrawal
Moving your own crypto balance off-platform to an external wallet. Must clear your account's single euro minimum — €300 on a standard account (XRP must keep ≥10 XRP in-wallet).
KYB
Know Your Business — verification of your company's legal identity, ownership, and documents.
KYC
Know Your Customer — verification of an individual's identity, such as your company directors.
AML
Anti-Money Laundering — the regulatory controls that KYB/KYC checks support.
UBO
Ultimate Beneficial Owner — any individual who owns 25% or more of the company.
Chargeback
A card payment reversal initiated by the cardholder's bank; forfeits the matching reserve.
Underpayment
When a customer sends less crypto than the invoice requires. Tolerance is 0% by default unless configured.
Chargeback case
A historical record of an IP or email block written by the legacy fraud system. Blocking is retired, so no new cases are created; the case number is the number that was shown to a customer when that block refused a payment.
Completion rate
Completed orders divided by all orders created in the period, including declined, expired, cancelled and still-processing ones. Refunded and charged-back orders count as completed.
Fiat integration
The set of return, failure and webhook URLs for one site. Its integrationId is passed when creating fiat orders from your own code.
Payout wallet
The wallet your card and fiat settlements are sent to. Up to three active wallets can be kept in Settings → Fiat; exactly one is the payout wallet.
Help request
A bug report or support request the Niftipay assistant forwarded to the team. Listed under Get Help in the dashboard, with a status that becomes Resolved when the team closes it.
Fingerprint check
The real-time device check that now decides whether a card payment can proceed, replacing manual device blocking. The Blocked Devices page is the audit history of the old system.
