One operational layer across payment rails
The architecture separates provider identifiers from PayMatrixAI's canonical transaction identity, so payment operations remain consistent as providers and rails evolve.
Provider-neutral payment layer
Application logic works against canonical PMX payment records rather than a provider-specific schema.
Explicit lifecycle
Payment state changes are validated server-side and represented as controlled transitions.
Idempotent writes
Repeated write requests can be safely replayed using durable idempotency keys.
Failure & event timelines
Operational history keeps payment state, failure reasons and provider events connected.
Sandbox payment methods
Test Visa, Mastercard, bank transfer and wallet-style flows without live-money movement.
Financial continuity
Payment activity connects to the universal ledger and downstream reconciliation workflows.
Production deployment requires separate provider connectivity, compliance approval, security verification and operational readiness. The current public experience remains sandbox/pre-production.
