Quantum Fintech Lab

Production-ready prototypes and reference architectures for US instant payments—FedNow, RTP, and ISO 20022—built with bank-grade resilience, fraud controls, and compliance automation.

Modern US payments need an overlay + trust layer

The US doesn’t have one universal "front door" to payments. Consumers and businesses bounce between cards (expensive), ACH (slow), and closed-loop wallets.

Our Lab builds the missing layer: Software that makes real-time rails usable, interoperable, and safe at scale. We focus on multi-rail orchestration and UPI-like primitives adapted for the US market.

Next-Gen Infrastructure

Built for the Quantum Age

Legacy banking cores run on COBOL and batch processing from the 1970s. Our system is engineered from the ground up for the speed, security, and complexity of the post-quantum era.

Yesterday's Systems

  • Monolithic & Fragile

    Single points of failure. Updates take months. Downtime is expected.

  • Vulnerable Encryption

    Standard RSA/ECC is susceptible to future quantum decryption attacks.

  • Batch Processing

    Data moves in "nacha files" overnight. Reconciliation is always T+1.

The Quantum Insider Advantage

  • Atomic & Event-Driven

    Microservices architecture. Transaction finality in milliseconds. 99.999% uptime.

  • PQC-Native Spec

    Built with Post-Quantum Cryptography standards (NIST finalists) ready for 2030+ security needs.

  • AI-Powered Liquidity

    Predictive models manage intraday liquidity automatically, optimizing capital efficiency.

We don't just patch the old system. We replace the foundation with mathematical certainty.

Credit Cards Aren’t Going Away —
We Design for Interoperability

The US payments system is deeply shaped by the open-loop credit card ecosystem. Quantum doesn’t try to replace cards. We build a multi-rail orchestration layer that integrates with card networks while expanding the reach of instant payments where they’re a better fit.

Where cards remain the best tool

  • Credit at the point of sale (revolving credit, financing)
  • Global acceptance + mature merchant tooling
  • Chargebacks and dispute frameworks consumers understand
  • Tokenization + strong fraud tooling embedded
  • Rewards economics that drive consumer behavior

Our approach preserves these strengths—and then modernizes everything around them.

Deeply entrenched ecosystem

The "Multi-Rail Decision Engine"

Card Rails
Best For:
  • • Credit purchases (financing)
  • • High-risk transactions
  • • Cross-border travel
Preserves rewards & protections
Smart Router
Instant Rails (FedNow/RTP)
Best For:
  • • Bill Pay & Rent
  • • Payroll & Disbursements
  • • P2P & Account Funding
Optimizes cashflow & data

Fallback Logic: If one rail is degraded, we route to the next best rail with safe retries and idempotency to prevent duplicates.

How we differ from UPI

"UPI-style" in the US isn't a copy—it’s an adaptation. India’s model is domestic-first and bank-centric. The US version must account for credit centrality and enterprise needs.

1

Credit + Rewards are Central

Quantum supports rail-agnostic incentives and keeps card rails where credit is the product.

2

Enterprise Reconciliation

ISO 20022-first workflows help B2B payments carry usable remittance data that cards often strip.

3

Higher Risk Pressure

We treat risk + compliance as first-class infrastructure, not a bolt-on.

More Economically Compelling

MerchantsLower cost options for debit-like transactions, fewer disputes, faster cashflow.
IssuersPreserve card economics for credit; reduce fraud losses with better identity patterns.
ProcessorsOne integration surface that supports multiple rails; differentiated fraud value.
NetworksParticipate through value-added services rather than being disintermediated.
Global Innovation, Local Reality

What "UPI-style" means in the US

We abstract the complexity of US rails to provide 5 frictionless user experience primitives.

Payment Addressing

Pay to email/phone/handle, not routing numbers.

Request-to-Pay

Merchant sends request; user approves in-app.

QR + Links

Frictionless in-person and remote checkout.

Interoperability

Any bank to any bank, seamlessly connected.

Instant Confirm

Settled and confirmed in seconds.

In the US, we implement these using FedNow/RTP for settlement with ISO 20022 rich messaging.

Frequently Asked Questions

Common questions from technical teams, compliance officers, and procurement.

How does multi-rail routing work?

Our Smart Router evaluates each transaction against configurable policies: cost (lowest fee), speed (fastest rail), risk (safest option), and availability (working rail). You can set static preferences or let the engine optimize dynamically. Fallback logic handles rail degradation automatically with idempotent retry patterns.

What happens if a payment fails on the primary rail?

The system automatically attempts the next best rail based on your policy configuration. All retries use idempotent keys to prevent duplicates. You receive real-time webhook notifications at each stage. If all rails fail, the transaction is queued with configurable retry schedules.

How do you handle fraud for instant payments?

Pre-transaction risk scoring runs in <10ms using graph neural networks that detect anomalous patterns. We support Confirmation of Payee to verify recipients before funds leave. Device binding, behavioral biometrics, and velocity limits provide layered defense. All decisions are logged for audit.

What's required for ISO 20022 compliance?

We handle the heavy lifting: message translation, validation, and enrichment. Our mapping library converts legacy formats to ISO 20022 and vice versa. Rich remittance data flows through end-to-end, enabling automated reconciliation that legacy systems can't match.

Can you integrate with our existing core banking system?

Yes. We have pre-built connectors for major cores (Temenos, FIS, Fiserv, Jack Henry) and a flexible adapter framework for custom integrations. Most implementations are completed within 8-12 weeks, with a sandbox available immediately for testing.

What's the pricing model?

Usage-based pricing with volume discounts. You pay per transaction processed, with no minimums or long-term commitments for cloud deployments. Enterprise and on-premise deployments include platform fees. Contact us for detailed pricing based on your volume and deployment requirements.
