Enterprise payment orchestration for healthcare, government & banks · registered MSP/ISO of Elavon, Visa & Mastercard

Dual-rail payment orchestration,
secured for the post-quantum era

PaychainX is the orchestration and post-quantum proof layer we built: an intelligent API router with tokenization, settlement, and a tamper-evident audit trail. It connects to CyberSource for card processing, is in pilot with Propelr, and is partnered with Zero Hash for stablecoin settlement. Purpose-built for regulated, high-assurance markets, medical payments, government, and banking, where every transaction is sealed with a post-quantum-ready cryptographic proof no legacy processor offers.

Figures reflect the PaychainX reference/sandbox environment, shown for demonstration. No production credentials or live cardholder data are exposed on this site.

Most gateways move transactions. PaychainX routes, secures, orchestrates, and proves them.

A complete gateway, not a single feature

PaychainX runs the full transaction lifecycle today across our reference and pilot environment. Post-quantum is the newest layer on top of an already enterprise-grade platform.

API router

Intelligent API router

One API. The router selects the right processor and rail per transaction, with retriable payment attempts and processor failover. Orchestration, not just a passthrough.

Dual rail orchestration

Dual-rail orchestration

Route the same payment intent across the card rail (live via CyberSource) and the stablecoin rails (settled by Zero Hash, B2C nearing production, B2B in design), one orchestration layer bridging traditional and digital settlement.

Tokenization

Tokenization & vaulting

Card data is replaced with a token at the edge (card_token). The PAN never touches merchant systems, shrinking PCI scope.

Omnichannel

Omnichannel acceptance

One gateway for online (channel: api) and card-present terminals (PAX A920 Pro, with terminal and device identity), with unified reporting across both.

Reliable webhooks

Reliable signed webhooks

HMAC-signed events with automatic retry and full delivery tracking (attempts, HTTP status, delivered or failed), so merchants never silently miss a payment update.

Reconciliation

Reporting & reconciliation

Daily transaction aggregates per processor, settlement lifecycle, and an admin search API over the full payment history with pagination.

One integration, every rail, under the hood

A merchant integrates once. Behind that single API, a router normalizes every payment, selects a rail, runs it through a uniform adapter, and seals the result in a tamper-evident proof. Here is exactly how it works in the gateway today.

The rails, and exactly what is live

PaychainX is the orchestration and post-quantum layer. CyberSource is the connected card processor, Propelr is our pilot partner, and Zero Hash is our stablecoin settlement partner. Every rail implements the same adapter contract, and we label precisely what is live versus on the roadmap.

Uniform rail adapter

Add a rail by implementing one interface. The router never changes.

interface ProcessorAdapter { sale(input): Promise<NormalizedPaymentResult>; capture(input): Promise<NormalizedPaymentResult>; void(input): Promise<NormalizedPaymentResult>; refund(input): Promise<NormalizedPaymentResult>; } type NormalizedPaymentResult = { processor: string; success: boolean; status: "authorized" | "captured" | "voided" | "refunded" | "failed"; processorTransactionId?: string; processorStatus?: string; };

The router

One function resolves a normalized payment to a rail.

function resolveProcessor(preferred = "cybersource") { switch (preferred) { case "cybersource": return new CyberSourceAdapter(); // live case "bank_rail": return new BankRailAdapter(); // roadmap default: throw new Error("Unsupported processor"); } }

Payment sources the router accepts:

sandbox_cardcybersource_transient_tokenbank_token

Safe retries by design, idempotency

Networks fail and clients retry. The gateway guarantees a retry never creates a second charge. Every POST /v1/payments/* requires an Idempotency-Key, and the body is fingerprinted so reuse is detected exactly.

requestHash = SHA-256( canonicalize( body ) ) same key + same body replays the stored response (x-idempotent-replay: true) same key + different body 409 IDEMPOTENCY_CONFLICT key still processing 409 IDEMPOTENCY_IN_PROGRESS missing key 400 IDEMPOTENCY_KEY_REQUIRED

Merchant onboarding, compliance, and dashboard

Near production

Merchant self-onboarding with identity and business verification, and a merchant dashboard for activity, settlements, and reporting. UI and UX are roughly 95 percent complete and nearing production.

The differentiator

Post-quantum-secured payment proofs

Every PaychainX payment emits a tamper-evident proof (proof_id: pq_…), an independently verifiable record of what happened. Each proof is sealed with ML-DSA-65 (FIPS 204), the NIST post-quantum signature standard, signed gateway-side with ML-DSA-65 today in our reference environment and independently verifiable in your own browser, so audit trails stay trustworthy even against a quantum adversary. No card processor on the market offers this.

Hybrid post-quantum audit

Built for regulated, high-assurance markets

Where a payment must be provable, private, and auditable, not just processed. PaychainX pairs dual-rail orchestration with post-quantum proof for the sectors that answer to regulators.

🏥

Healthcare & medical payments

Patient payments, claims, and provider settlement with tokenized card data, tamper-evident proofs for every transaction, and an audit trail built for HIPAA-grade accountability. Dual-rail lets payers settle by card or stablecoin.

Target vertical
🏛️

Government & public sector

Disbursements, benefits, and cross-agency payments with cryptographic, independently verifiable evidence for every movement of funds, sovereign deployment, and multi-currency reach for programs that must withstand audit.

Target vertical
🏦

Banks & enterprise

A single integration that routes across card and settlement rails with processor failover, idempotency, and reconciliation. Deploy as a license, white-label gateway, or internal routing infrastructure. Registered MSP/ISO of Elavon, Visa & Mastercard.

Card rail live

Vertical positioning reflects PaychainX's target markets. Card rail is live via CyberSource; stablecoin settlement is partnered with Zero Hash (B2C nearing production, B2B in design); capabilities are labeled live vs. roadmap across the site.

Built for global deployment

PaychainX is processor and rail agnostic by design, so a single integration can serve enterprises, banks, and governments across regions and settlement networks. The gateway already runs behind a global edge network with TLS at every hop.

PaychainX deployable across global regions and settlement networks
🌐

Global edge network

Requests are served over HTTPS behind a worldwide edge, keeping routing overhead low wherever the merchant or terminal sits.

💱

Cross-border and multi-currency

The canonical request carries currency on every transaction, the foundation for cross-border acceptance and multi-currency orchestration.

🏛️

Enterprises, banks, governments

Deploy as a license, a white-label gateway, or internal routing and settlement infrastructure for regulated, high-assurance markets.

Regions shown represent target deployment reach. PaychainX is a registered MSP/ISO of Elavon, Visa, and Mastercard. Cross-border, multi-currency, and additional settlement rails are a mix of live and roadmap capabilities, labeled as such across the site.

Built for the controls banks require

We separate what is live today from what is on the roadmap, with no overstated production claims.
