International Payments & Global Rails

While local payment rails unlock emerging market conversion, international customers expect seamless credit card processing, 3D-Secure authorization, and mobile wallets (Apple Pay and Google Pay).

[1. International Customer (USD/EUR/GBP)] ➔ [2. Route to Global Rail (Stripe)] ➔ [3. 3DS / Apple Pay Auth] ➔ [4. Direct Settlement to Your Bank]

SolydFlow enables African and cross-border businesses to accept international card payments globally by connecting Stripe or Paystack International, while managing transactions and entitlements alongside domestic rails.

A critical architectural pillar of SolydFlow is that we never sit in the flow of your money:

(Zero Access to Funds)
  1. Direct Payouts: Funds clear directly into your company’s registered merchant bank accounts according to your gateway's standard payout schedule.
  2. Zero Escrow Risk: Because SolydFlow is not a financial intermediary, your revenues are never frozen, pooled, or subject to third-party reserve withholdings.
  3. Transparent Merchant Records: Your customers see your business name on their credit card statements.

Hedging Against FX Devaluation​

For African software companies operating in volatile currency environments, selling to international customers in hard currencies is essential for protecting profit margins:

  • Base USD Anchor: You can configure your global tier as pro_monthly_usd ($4.99 USD or $19.99 USD).
  • Automated Smart Routing: When an international customer accesses your web app from London, New York, or Berlin, SolydFlow serves the USD price and routes to Stripe automatically.
  • Unified Accounting: SolydFlow records the transaction in your Immutable Ledger alongside local Naira and Shilling purchases, maintaining unified customer entitlement state.

Developer Experience: Global Checkout​

// Automatically routes international users to Stripe Card / Apple Pay:
final CustomerInfo? info = await SolydFlow.purchasePackage(
context,
"pro_monthly_usd", // $4.99 USD base tier
);

if (info?.activeEntitlements["pro_access"] == true) {
debugPrint("Global subscriber access active!");
