Each business selects its shop currency in Store settings. Existing listing source prices are not rewritten when the business currency changes; Tuaneka converts display and transaction values using saved exchange rates.
The public Tuaneka marketplace is Ghana-first and displays prices in GHS. USD-to-GHS conversion uses the latest available Bank of Ghana interbank mid-rate and records the provider and rate date on the order. Weekends or holidays may use the latest saved BOG rate. Checkout recalculates price and exchange rate server-side.
Marketplace checkout requires the seller's enabled Paystack or Stripe connection. Sellers may connect both and let buyers choose. Tuaneka verifies the provider, reference, amount, currency, buyer email and store ownership and processes duplicate callbacks only once. Provider secret keys are encrypted and never shown again after saving. Never send secret keys, card data or verification codes through support.
