Hosted payment
Card, PayPal, and cryptocurrency credentials are handled by the selected provider. ReachViva does not store raw card numbers, CVV values, wallet keys, or seed phrases.
Server-authoritative totals
The server loads the active package and creates payment using its expected amount. Browser-supplied prices are never trusted.
Verified events
Signed webhooks or reconciled captures must confirm the exact amount and currency before an order is paid. Unique checkout, provider, and event identifiers prevent duplicate processing.
