Oradian Custom Code: The Power to Move Faster

With Oradian Custom Code, your tech team can embed custom logic directly into your core banking system. Custom Code belongs exclusively to you (IP) and only you can see it.

Endless configurations are possible with Oradian. We are API first, which means you can plug and play pretty much anything. But if all of that isn’t enough, we’ve got one more thing: Custom Code, allowing you to write your own nuanced logic for even more customisation.

Most systems force you to choose between customisation and stability. With Oradian, you get both. Custom Code gives your team the ability to extend product logic, automate workflows, or respond to market demands faster than any roadmap update could.

Whether it’s changing the way you calculate fees, launching a new pricing structure, or reacting to new regulations, you can build exactly what you need, and do it without waiting for vendors.

Built for ambitious teams

Oradian Custom Code is ideal for:

  • Institutions with strong tech teams or system integrators
  • Fast-growing lenders expanding across new customer segments or markets
  • Banks with specific compliance requirements or non- standard workflows
  • Fintechs looking to differentiate their UX or pricing models

Teams who want control over their core, this can work as an alternative to going fully in-house

A smarter way to customise your core

Custom Code means you never have to relinquish control again. It puts your system on steroids, letting you move faster, stay scalable, and stand out in the market without compromising your infrastructure.

What you get with Custom Code

Custom Code creates a safe environment within your Oradian system that lets you deploy custom logic without risking scalability, system speed or reliability and accuracy of calculations.

You get access to:

External JARs

Write and upload code that plugs directly into the core without breaking it, that includes use cases like fee logic, daily processing, or custom triggers.

Custom APIs 

Build bespoke endpoints that do exactly what your workflow needs, without depending on vendor timelines. With Custom Code, you can create commands that trigger actions, call external APIs, and feed results straight back into Oradian.

Advanced formulas

Implement calculated expressions, custom logic or fees, penalties, interest calculations or end of day processing.

Fraud readiness toolkit for digital banks and lenders

You can't fix what you can't see. This toolkit shows you exactly where your fraud defences are exposed.

Fraud-as-a-service means attackers now iterate weekly, while many institutions still respond in batches and rule updates that take weeks. The gap between the two is precisely what fraudsters exploit, and it's widening as regulators across Nigeria, the Philippines, and Indonesia tighten their requirements on real-time detection, AI explainability, and customer notification.

This toolkit gives product, risk, technology, compliance, and operations leaders a clear, honest picture of where they stand. It comes in three parts: a Fraud Readiness Checklist to surface the gaps costing you in losses, regulatory exposure, and unattributed churn; a scoring model that places your institution on a four-level maturity scale; and a 90-day action plan that tells you exactly where to focus first.

You don't need to solve everything at once. You need to know what to do next. Complete it with the people who know the real answers, your technology lead, your compliance officer, your fraud team, and you'll leave with a defensible starting point and a clear direction of travel.
