Frequently Asked Questions on Domain Architecture
How do you prevent race conditions and duplicate charges in high-volume payment ledgers?
We implement idempotent API request tokens combined with strict database transactions and PostgreSQL row-level locks (SELECT FOR UPDATE). Every transaction generates an immutable double-entry journal entry that must balance before commitment.
Can you assist with PCI-DSS compliance and payment processor approvals?
Yes. We architect your frontend using tokenized elements (e.g. Stripe Elements / Hosted Fields) to keep your servers out of PCI scope (SAQ A-EP), while encrypting all database payloads with AWS KMS and AES-256.
How are multi-currency cross-border exchange rates handled?
We integrate automated forex rate providers with configurable spread buffers, real-time rate locking during checkout, and settlement tracking to protect against currency volatility.
Can we integrate automated identity verification (KYC)?
Yes, we integrate with industry leaders like Sumsub, Onfido, and Persona to provide automated document verification, biometric facial recognition, and AML watchlist screening directly inside the user onboarding flow.
