The Problem

In Nigeria and the African continent at large, buying and selling crypto is usually a messy, confusing process. Between navigating clunky apps, dodging sketchy vendors, and dealing with inconsistent platforms, the average user ends up wasting time, money, or both.

Common user complaints:

• Long and stressful onboarding processes

• Overly complex flows just to make simple trades

• Lack of trust in platforms

• No way to easily fund everyday needs like airtime and data

There was a huge opportunity to build a clean, simple, trust-first platform that made trading crypto feel like sending a text.

The Solution: Koinpoint

Koinpoint offers an ultra-simplified experience where:

• Users can purchase BTC, ETH, or USDT with ease

• Gift card exchanges happen seamlessly

• Airtime and data top-ups are available directly within the app

• Everything runs on clean UX, tight flows, and zero unnecessary steps

My Role

I led the entire product design process from zero to final prototype in just three weeks:

• Defined the information architecture

• Conducted user research to uncover local pain points

• Sketched out and tested low-fidelity wireframes

• Delivered high-fidelity screens and full interactive prototypes

• Prioritized UX clarity and speed over clutter and complexity

Design Philosophy

I built Koinpoint around simplicity, trust, and speed. No hidden steps. No confusing jargon. Just clean visuals and fast actions. The design goal was: “If your grandma can use WhatsApp, she should be able to use Koinpoint.”

Standout Design Principles:

• Minimal flow to complete a transaction

• Instant access to key actions like buy, sell, top-up

• Use of familiar mobile patterns to lower the learning curve

• Local context awareness—designed for how people in Nigeria actually use financial apps

Design Process

• Week 2: IA, wireframes, and iterative testing

• Week 3: High-fidelity UI, interactive prototype, and design handoff

Everything was scoped tightly to maximize user value and minimize bloat.

Outcome

Koinpoint’s design was completed on schedule with a final prototype that’s currently positioned for development. It’s sleek, intuitive, and tailor-made for real-world crypto users in Nigeria.

What I Learned:

• Speed matters—users want fast decisions and even faster actions

• Designing for local markets means empathy over aesthetics

• Fewer steps = more trust in financial platforms

• And most importantly: if it looks simple, it’s probably well-designed
