2025: SCALING FINANCIAL INFRASTRUCTURE ACROSS MULTIPLE REGULATORY CONTEXTS

2025 was a year when financial infrastructure had to operate without pause — regardless of pressure, load, or constant regulatory change.

Expectations around speed, transparency, and control continued to rise. In such conditions, technology stops being an enabler and becomes the platform that either holds the system together — or doesn’t.

For Lime Systems, this meant navigating multiple regulatory environments, running high-velocity projects under strict timelines, and delivering mission-critical integrations where operational continuity was non-negotiable.

Below is a snapshot of 2025 as an operational reality: increasing loads, evolving standards, expanding system boundaries, and growing architectural complexity. This is the experience shaping our next stage.

Financial infrastructure modernization across instant payments, cross-border
payments, sanctions and AML screening, tax reporting and management reporting.

2025 PROJECTS & SOLUTIONS: KEY MILESTONES

Scaling financial infrastructure across multiple regulatory contexts for banks, non-bank payment providers and financial institutions in 2025.

INTERNATIONAL PROJECTS: MULTIPLE REGULATORY CONTEXTS AND ARCHITECTURAL MODELS
Throughout 2025, Lime Systems worked on international projects in the UK, EU markets, and Central Asia. The work covered different regulatory environments, delivery tempos, and architectures, including cloud-based solutions and phased financial module rollouts. Detailed case descriptions will follow separately.

SWIFT ISO 20022: MIGRATION AT SCALE ACROSS OUR CLIENT BASE
Across the active client base, SWIFT ISO 20022 adoption became a major modernization milestone: structured message handling, controlled coexistence with legacy formats, and governed conversion between standards. The migration established a stable foundation for cross-border payments, leveraging data-rich messaging to enhance compliance automation and straight-through processing (STP) in line with the latest SWIFT requirements.

INSTANT PAYMENTS: REAL-TIME PROCESSING AS A DEFAULT OPERATING MODE
All banks operating on Scrooge (core banking platform) were transitioned to full instant-payments processing aligned with a national electronic payments system. The capability covers the complete payment lifecycle, from initiation to beneficiary credit, in real time.

ENABLING END-TO-END PAYMENT VISIBILITY VIA REAL-TIME TRACKING
Within selected client deployments, an end-to-end payment tracking mechanism was implemented to expose payment status across processing stages. The approach relies on automated event synchronization from the payment layer and API access to a centralized tracking service, enabling front-end channels to display real-time status to end users. Rollout began with several high-volume institutions and is planned to expand further.

FATCA REPORTING: REGULATORY COMPLIANCE UNDER US LAW
At platform level, the reporting module supporting obligations under the US FATCA law was optimized for routine regulatory use. It covers data preparation, standard-aligned validation, and final XML report generation, enabling FATCA compliance as part of daily operations without manual handling or data-loss risk. Available to Scrooge core banking users.

SAF-T UA: PREPARATION FOR MANDATORY TAX REPORTING
SAF-T UA implementation projects were initiated to prepare for mandatory audit-file reporting. The solution is delivered as an autonomous, low-impact SAF-T module using Scrooge Analytics as a data aggregation platform. It allows banks to automate SAF-T independently of their core banking system by connecting both internal and external accounting data sources without disrupting core operations.

SANCTIONS & AML SCREENING: OPERATIONAL SCREENING ENGINE EMBEDDED IN TRANSACTIONS
Within selected client projects, a sanctions screening capability (FinTrace) was deployed using fuzzy matching on Elasticsearch, built with a microservice architecture and embedded into operational workflows across Scrooge and WebBank. Screening runs directly inside transaction scenarios using international sanctions sources, internal watchlists, and institution-specific lists. External integration is supported via FinTrace API.

STATE SANCTIONS REGISTRY INTEGRATION: AUTHORITATIVE AML DATA SOURCE
Integration with a national state-maintained sanctions registry was implemented as a core AML capability. The registry is used as a single authoritative data source embedded into operational screening workflows. The solution is production-ready and being rolled out across client projects.

MANAGEMENT REPORTING & BUDGETING: A UNIFIED MANAGEMENT ENVIRONMENT
Within a client project, a large-scale implementation was initiated to automate management reporting and budgeting for one of the biggest universal commercial bank. The target architecture consolidates management data, supports plan-vs-actual control, and enables consistent profitability analysis. The project starts in 2025 and continues during 2026, with results to be detailed after completion.

STREAMLINING REGULATORY REPORTING VIA DIRECT REST API INTEGRATION
Within a client project for a large non-bank payment provider, a direct REST API integration with a national tax authority was implemented to automate reporting of account openings and closures without third-party software. The solution covers register submission, receipt/status handling, and automated updates within the client registry, enabling stable, daily, auditable regulatory exchange.

CORPORATE CLIENT PLATFORM: CONTINUOUS DEVELOPMENT + CLIENT-SPECIFIC CUSTOMIZATION
Across the iTiny client platform (a digital financial hub for retail and business clients), ongoing UI modernization, functional expansion, and API enablement were delivered. In parallel, within a client-specific deployment, targeted customization was implemented for a high-volume non-bank financial partner, including corporate payment controls, document and certificate generation, and B2B process tailoring.

CROSS-BORDER B2B PAYMENTS: VISA B2B CONNECT AS AN ALTERNATIVE TO SWIFT
Implemented Visa B2B Connect integration in close cooperation with one of the commercial banks and the Visa network, enabling cross-border B2B payments without correspondent chains as a SWIFT alternative. The service provides upfront fees, predictable settlement timing, and richer remittance data, reducing errors and simplifying reconciliation for internationally active companies.

FACTORING WITH RECOURSE: LIQUIDITY MANAGEMENT FOR CORPORATE CLIENTS
A standard “factoring with recourse” product capability was implemented for the same bank. The instrument enables businesses to access working capital against future receivables without waiting for buyer payment, while keeping credit-risk allocation defined. The capability is used as an operational liquidity tool in daily corporate finance scenarios.

CENTRAL BANK CROSS-BORDER LIMITS: REGULATORY CONSTRAINTS EMBEDDED IN CORE OPERATIONS
A dedicated Scrooge module integrates a central bank system governing individual cross-border investment limits directly into daily banking workflows. Limit checks, regulator requests, and operation registration are executed inside core processes (including FX control), eliminating external workflows and manual reconciliation.

NON-BANK PAYMENT PLATFORM: RECORD TIME-TO-MARKET DELIVERY
The first phase of a licensed non-bank payment platform was delivered from scratch within a record-to-market timeframe to meet strict regulatory deadlines. The scope covered a full payment stack, including ledger, card backend, authorization, national payment rails, AML, and regulatory reporting. The platform passed regulatory approval and continues into the next phase.

FROM SYSTEMIC STABILITY TO STRATEGIC SCALING

2025 for Lime Systems was a year of work that often remains invisible — because stability is often silent. That’s exactly what makes it resilient.

We focused less on commentary and more on ensuring that financial infrastructure continues to operate predictably across payments, compliance, and regulatory processes.

Our teams worked in parallel across domestic and international projects, preparing systems for new standards, higher loads, and environments where downtime is not an option.

We enter 2026 with proven implementations, established standards, and experience that allows us to approach complexity without haste. The next phase is about scaling what already works — and deepening partnerships built on trust and delivery.
