Under the Hood: Powering Real-Time Banking with Vestigo’s Instant Payment Connector

  • November 18, 2025

Ana Bojanić

Product Manager

In today’s fast-paced digital world, “instant” is the new standard. From messaging to media, consumers expect immediate results, and financial transactions are no exception. The era of waiting days for payments to clear is over. This shift is driven by the SEPA Instant Credit Transfer (SCT Inst) scheme, which is reshaping the European payments landscape.

For banks, this presents both a regulatory challenge and a strategic opportunity. The upcoming EU mandate requires all banks offering euro transfers to provide an instant version by 2025, processing payments within 10 seconds, 24/7/365. Meeting this demand requires more than a simple update; it often involves navigating complex legacy systems not built for real-time operations.

At Vestigo, we thrive on this complexity. Our Instant Payment Connector is a purpose-built solution that enables banks to embrace the instant economy. Already in production at two banks, our connector is successfully processing both incoming and outgoing instant payments, turning a complex challenge into a competitive edge.

The Challenge: Bridging Legacy Systems with Instant Demands

Traditional banking infrastructures were designed for batch processing, where payments are settled during specific business hours. SEPA Instant, however, operates continuously. This requires a fundamental change in how transactions are handled, demanding real-time processing, continuous availability, and instant liquidity management.

Many financial institutions face significant hurdles:

  • Technological Overhaul: Legacy core banking systems often lack the capability to handle real-time payment processing, making integration a major obstacle.
  • Operational Strain: The need for 24/7 monitoring and instant fraud detection places new demands on operational teams.
  • Complex Integration: Connecting to Clearing and Settlement Mechanisms (CSMs) like the ECB’s TIPS or EBA Clearing’s RT1 requires specialized interfaces and adherence to strict protocols.

The Architecture of the Vestigo Connector

Vestigo’s solution is built on a modern architecture. Our Instant Payment Connector is a modular component of the Vestigo Payments Hub – a cloud-born, API-driven payments platform In practice, Vestigo’s connector handles both outgoing instant payments from the bank to the SCT Inst scheme) and incoming payments (from the scheme to the bank).

API-First Architecture: The connector exposes RESTful APIs for core systems. Banks simply call these APIs (for outgoing payments) or receive push notifications/webhooks (for incoming payments) This will make integration straightforward and riskless for core system and other payment processing.

ISO 20022 Support: The connector fully implements the SCT Inst messaging standards (e.g. pacs 008 for credit transfers, pacs 002 for status reports). Because SEPA Instant uses ISO 20022, it “simplifies” integration with various banking systems and eliminates the need for banks to reformat messages.

Performance: Designed for high throughput and 24/7 availability, the connector runs in a scalable cloud and container environment and meets SCT Inst’s real-time performance requirements.

For banks’ IT teams, this means they can plug in instant payments with minimal fuss. Our connector is platform-agnostic (it can run on distributed systems, mainframes or cloud) and easily integrates alongside existing legacy systems. In many cases the core system only needs a lightweight adapter or a few API calls to interface with Vestigo’s service.

Key benefits of this approach include:

  • Immediate Funds Access: Recipients see the credit instantly. Vestigo’s system passes the settlement confirmations to the core in seconds, so customers have instant access to their funds. This “up-to-the-minute visibility into cash positions” also greatly improves banks’ liquidity management
  • Scalability: Container and cloud deployment allows banks to scale the service as transaction volumes grow. New banks can spin up the connector quickly, without long hardware procurement cycles.
  • This entire process is completed in under 10 seconds, ensuring full compliance with the SEPA Instant mandate.

More Than Speed: Features That Drive Operational Excellence

While speed is crucial, a truly modern payment solution delivers reliability and insight. Our connector is part of the integrated Vestigo Payments Hub and is complemented by our Instant Payment Dashboard, providing a unified view of all transaction activity.

Key features include:

  • Real-Time Monitoring: Gain up-to-the-second insight into transaction statuses, processing times, and routing paths. This allows for instant identification of delays or failures, enabling rapid intervention.
  • Actionable Analytics: The dashboard provides advanced analytics on payment patterns and peak volumes. Banks can track key metrics, such as rejection codes (e.g., TM01 for timeout, AG01 for invalid account), to address root causes and optimize performance.
  • Streamlined Integration: Designed for smooth integration, our connector allows banks to preserve their existing core system investments while seamlessly connecting to the instant payment ecosystem.

Delivering Real Value Today

This technology is not just a blueprint for the future; it’s a proven solution delivering results now. With Vestigo’s Instant Payment Connector already live in two banks for both incoming and outgoing payments, we have demonstrated our ability to navigate complex integrations and deliver a robust, reliable, and compliant instant payment service.

Vestigo’s underlying Payments Hub was explicitly built to future-proof banks’ payment infrastructure. It covers all payment types (instant, standard SEPA, cross-border, high-value, etc.) with unified The Instant Connector is simply one module of this platform. Because the platform is cloud-native and API-first, adding new features or scaling up is straightforward – banks can innovate without the risk of legacy bottlenecks.

By using Vestigo’s connector, banks gain:

  • Regulatory Compliance: Full support for the 2025 SCT Inst , including the requirement to credit recipients within 10 seconds. Vestigo’s solution meets these rules out of the box.
  • Faster Innovation: The connector’s API framework lets banks extend services quickly. For example, offering instant payments in a mobile app can be done by calling Vestigo’s APIs, not by building a whole new back-end.
  • Reduced Complexity: Because SEPA Instant uses a single ISO 20022 standard for all countries, banks avoid the “patchwork” of legacy country-specific systems. Competitive Edge: Instant transfer capability is increasingly demanded by corporate and retail customers. Being able to promise near-immediate fund delivery (around the clock) is a strong differentiator in the market.

In summary, the combination of standard ISO, cloud-based and connectivity to TIPS/RT enables Vestigo’s connector to deliver true instant payment capability. It’s now production-ready, already serving live traffic in multiple banks. This means our clients can offer full incoming and outgoing SEPA Instant payments immediately – with minimal integration effort, modern APIs, and the assurance of a fully compliant, high-performance system.

By partnering with Vestigo, banks can confidently step into the future of payments, enhancing customer satisfaction, improving operational efficiency, and transforming a regulatory requirement into a lasting competitive advantage.
