We take a lot of pride in how fast money moves in Nigeria. Ask anyone who has used a mobile banking app, a fintech wallet, or even a traditional bank’s USSD platform, and they will likely mention how funds arrive in seconds. Whether it is paying a vendor, settling a friend, or topping up airtime, real-time transactions have become part of everyday life. It has become a badge of honour for Nigeria’s financial system, evidence that we are not behind.

In truth, this is something we should celebrate. Real-time payments have revolutionised access to money, reduced the friction of cash-heavy transactions, and powered a new wave of digital commerce. But beneath this efficiency is a less talked-about reality, one that is beginning to show cracks.

For every instant transaction that works as expected, there are dozens that fail, delay, or disappear without clear explanation. Ask merchants how often they are told to “wait for a reversal” or customers how frequently they hit refresh on an app hoping to see an update. These experiences are frustrating, not just because they cause inconvenience, but because they erode trust. Over time, that erosion becomes difficult to repair.

This is not just a user experience problem. It is an infrastructure problem. And it is one that we are going to have to confront seriously if we want to build a digital economy that can scale.

Instant transfers rely on a complex dance between financial institutions, payment service providers, switches, and APIs. There is a lot going on under the hood, and much of it depends on uptime, interconnectivity, and systems that were not always designed with today’s volumes in mind. Nigeria’s payment infrastructure has come a long way, but the rate of adoption has outpaced the rate of backend innovation. What was once “advanced” is now strained.

Behind the scenes, fintech companies spend a disproportionate amount of time and resources managing these cracks. They build fallback mechanisms, retry queues, reconciliation tools, webhooks, and escalation paths just to keep up the illusion of reliability. Some of these companies run entire support teams just to follow up on failed transfers. And yet, the end user does not know, and often does not care, what went wrong. They just want their money to arrive.

For banks and legacy institutions, the pressure is even more intense. Many core systems were built in eras where volume was predictable and traffic was linear. Today, we are in an always-on environment, where users transact across time zones, devices, and layers. Supporting real-time transfers under this kind of load is not a matter of simple upgrades. It requires architectural rethinking and long-term investment.

But the real cost is often invisible. It is not just measured in failed transactions or support tickets. It is measured in broken trust, lost revenue, abandoned carts, and the long-term hesitation that people develop when they are unsure a transfer will go through. In some communities, fintech apps are only trusted for airtime, not transfers. In others, users still “test” apps with small amounts to see if they work before moving larger sums. This lack of confidence is not irrational, it is learned.

We need to rethink our obsession with speed. Fast is good, but fast without resilience is risky. Not every transaction needs to be instant. What users value more is reliability, the confidence that when they hit “send,” the money will get there, even if it takes a few extra seconds. Systems should fail gracefully, communicate clearly, and prioritise accuracy over artificial speed. We should not be chasing instant for its own sake.

In some cases, a slightly delayed transaction with a clear message and confirmation of expected delivery may be preferable to a system that promises real-time but collapses unpredictably. We need to normalise infrastructure conversations in the fintech space, not just UX, fundraising, or flashy features. Infrastructure is the backbone of everything else.

We can also take lessons from more mature systems. The UK’s Faster Payments Service was not built overnight. It went through multiple stages of iteration, policy enforcement, and technology upgrades. India’s UPI has become a global case study, but it still faces challenges with service-level agreements across banks and fintechs. These systems work not just because of tech, but because of discipline, monitoring, and clear responsibility for failure.

In Nigeria, we need to stop pretending that we are only one API away from world-class infrastructure. The truth is more complicated. Our infrastructure must reflect our context. That means taking into account power issues, device diversity, network unreliability, fragmented institutions, and rapidly growing user bases. It means designing for chaos, not perfection. Building for edge cases, not just the happy path.

This is a call to fintech founders, engineers, banks, and regulators. Let us begin to value infrastructure resilience with the same energy we give to innovation. Let us treat uptime, observability, and graceful failure as product features, not backend tasks. Let us have honest conversations about what it takes to deliver not just convenience, but reliability.

Because in the end, the real foundation of digital transformation is trust. And trust is not built on speed alone. It is built on systems that work, even when no one is watching.
