PROJECT VALUE
Client Overview
XOALA is a fully regulated Swedish neo-bank and all-in-one financial platform providing corporate banking, global payments, acquiring, and cryptocurrency solutions through a unified portal. Serving financial institutions, brokers, crypto firms, iGaming companies, and global businesses, XOALA brings multiple financial services together within a single platform.
As the platform evolved, XOALA needed to modernize its core backend while continuing to support parallel banking, card acquiring, and crypto workflows. The existing architecture also required stronger auditability, clearer access controls, and improved maintainability without disrupting live payment, IBAN, and wallet operations.

Project Background
XOALA, a regulated Swedish Electronic Money Institution, operates an all-in-one fintech platform for global businesses. It handles multi-currency accounts, virtual IBANs, card acquiring, crypto exchanges, and high-volume payments across 180+ countries. Acquaint Softtech took full ownership from analysis to deployment.
Modular Refactoring: Broke legacy monolith into clear, maintainable services for faster iteration and scalability.
Regulatory-Grade Security: Added encrypted storage and strict access guards to protect sensitive financial data.
Zero-Downtime Delivery: Modernized incrementally so operations never paused, preserving revenue and trust.
They worked as an extension of an internal engineering team as opposed to an external vendor

Founder, XOALA
Research & Ideation
We started by deeply embedding in XOALA's operations. Through structured discovery sessions with their engineering and compliance teams, we mapped every workflow. This includes payments, crypto trades, card issuing, and audit needs. This revealed pain points: fragmented logs slowed incident response, loose access controls risked compliance, and rigid code hindered new features.
Workflow-First Mapping
Aligned enterprise app modernization steps with real operational sequences to minimize disruption.
Compliance as Foundation
Built auditability and access controls early to satisfy regulators from day one.
Performance Guardrails
Designed every layer to maintain speed under high transaction loads.
Creative Design
We applied clean, disciplined architecture design to the backend. Using Laravel's strengths, we created modular services with clear boundaries, intuitive logging structures, and streamlined API layers. The result: a backend that feels modern and predictable, easy for internal teams to audit, extend, and trust under regulatory scrutiny.
Challenges
Handling Live Financial Workflows Without Disruption
Modernizing core banking, acquiring, and crypto logic while millions in transactions flowed daily demanded surgical precision; any outage meant lost revenue and eroded trust.
Translating Regulatory Needs Into Code
EMI, card scheme, and crypto rules required deep audit trails and role-based access, but legacy code obscured who accessed what and when.
Balancing Security With Speed
Adding encryption, logs, and guards risked slowing APIs critical for real-time payments and FX conversions.
Maintaining Scalability Under Growth
The platform needed to handle a growing user base, assets, and geographies without performance degradation.
Our Solutions
Acquaint Softtech delivered a layered, incremental modernization that strengthened XOALA's backend without breaking stride. We refactored legacy code into modular Laravel services, embedded enterprise-grade security, and ensured full traceability, turning a fragile system into a compliant, scalable foundation ready for growth.
Modular Backend Refactoring
Legacy financial and crypto workflows were decomposed into clearly defined, modular services. This improved maintainability and reduced systemic risk across banking, card, and crypto operations.
Encrypted Data Architecture
Sensitive operational and compliance data was secured through structured encryption mechanisms, aligned with EMI, card scheme, and crypto licensing expectations.
Comprehensive Audit Logging Framework
We implemented complete, readable audit trails mapped to user actions, API calls, and system-level events. Investigations no longer require cross-referencing fragmented systems.
Hardened API Authentication
Authentication flows were strengthened across internal services and third-party integrations, reinforcing security boundaries without slowing performance.
Custom Functionalities
XOALA operates as a fully regulated, all-in-one financial portal combining corporate banking, global payments, acquiring, and cryptocurrency services. The system needed enhancements tailored to parallel financial workflows operating inside a unified platform.
Parallel Workflow Stabilization
Backend restructuring ensured banking, card acquiring, and crypto processes could operate simultaneously within a single portal, without operational conflicts.
Regulatory-Ready Traceability Layer
Custom audit logic ensured every operational action could be traced clearly and efficiently, supporting compliance reviews and external regulatory scrutiny.
Predictable Incident Investigation Framework
We designed logging and visibility structures that simplified internal reviews. Teams could instantly validate who accessed what data and when.
Performance-Neutral Security Reinforcement
Security depth was added without degrading system responsiveness. Unlike many modernization initiatives, resilience improved while transaction speed remained stable.
Operational Access Mapping
Custom access boundaries mirrored real-world team responsibilities, reducing internal friction and strengthening governance.
On Going Support
Enterprise banking systems demand continuous oversight. Following the enterprise app modernization of XOALA, we provide structured post-deployment support focused on backend stability, regulatory alignment, and performance continuity. This includes proactive security hardening, audit log validation, infrastructure monitoring, and controlled feature enhancements, without disrupting live banking, payment, or crypto operations.
Performance Optimization
We continuously monitor transaction throughput, API latency, and system load across banking, acquiring, and crypto workflows. Where required, we fine-tune services to maintain predictable performance under growth.
Regulatory & Security Updates
As compliance expectations evolve across EMI, card schemes, and crypto licensing, we implement structured updates to access controls, authentication layers, and audit frameworks to ensure ongoing alignment.
Third-Party & Integration Support
From payment processors to crypto service providers, we maintain and optimize external integrations to ensure secure authentication flows and uninterrupted interoperability.
Project Outcome
For XOALA, the modernization delivered immediate structural clarity across banking, acquiring, and crypto operations. Internal reviews became significantly faster. Compliance checks no longer require piecing together fragmented data. Audit trails were complete, readable, and tied directly to user actions, system events, and API calls.
Acquaint Softtech managed the engagement with the discipline required in regulated fintech environments. The result was a modernized backend foundation built for growth, compliance scrutiny, and long-term maintainability. XOALA gained a system that behaves predictably under pressure, where security, traceability, and scalability coexist without friction.
