Start with Primer — highest vibe code, weakest moat.
Airwallex
Airwallex is a regulated financial institution providing direct access to SWIFT, local clearing networks, multi-currency IBAN provisioning, and Visa/Mastercard card issuing. While an AI agent can build a frontend dashboard or an internal double-entry ledger in a weekend, it cannot replace money transmitter licenses, wholesale FX liquidity lines, or central bank clearing integrations.
you can rebuild
- Internal multi-currency balance dashboard
- Basic double-entry ledger for internal record keeping
- Transaction tagging and expense categorization UI
- Custom invoice generation with multi-currency payment instructions
- Internal approval workflows for payout requests
what you lose
- Native multi-currency virtual IBAN generation (USD, EUR, GBP, AUD, JPY)
- Direct SWIFT and local clearing network settlement (ACH, SEPA, FPS)
- Visa and Mastercard virtual card issuance and spending limits
- Wholesale FX spot rate execution and hedging capabilities
- Global regulatory compliance, KYC/AML screening, and Money Transmitter Licenses
real moats
- Global regulatory licensing (EMI / MTL licenses across North America, EU, UK, HK, SG, AU)

Primer
Building basic logic to failover between Stripe and Adyen in Node.js takes a few days. However, Primer provides PCI-DSS Level 1 card vaulting, 3DS2 orchestration, unified tokenization, and dozens of pre-built payment connectors. Replacing Primer with custom code creates massive regulatory and engineering overhead.
you can rebuild
- Basic conditional payment routing (if Gateway A fails, try Gateway B)
- Rule-based PSP selection by buyer currency or country
- Basic payment transaction logging and status dashboard
- Dynamic surcharge calculations based on payment method
- Centralized webhook aggregation for payment status events
what you lose
- PCI-DSS Level 1 compliant card tokenization vault
- Pre-built integrations for 100+ PSPs, BNPLs, and alternative payment methods
- Native 3DS2 (Strong Customer Authentication) flow orchestration across gateways
- No-code visual drag-and-drop payment workflow automation editor
- Unified financial reconciliation and automated payout matching across processors

- PCI-DSS Level 1 security architecture and ongoing audit compliance
- Universal card vaulting and token format translation between legacy gateways
- Battle-tested maintenance of dozens of volatile payment processor APIs
