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.
