Koinpoint Crypto Trading Platform Design

Koinpoint is a mobile-first platform that allows users to buy and sell crypto assets (BTC, ETH, USDT), perform gift card transactions, and top up their data and airtime—all in one place. The mission was simple: cut the fluff and kill the stress of trading crypto in Africa. I set out to create a sleek, intuitive product that merges crypto utility with everyday life services, giving users a one-stop shop that’s fast, simple, and accessible.

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.

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.

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

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

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.”

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

Available for all major Nigerian networks

Pay with wallet balance or card

Track recent activities

Smart shortcuts to core features

Secure authentication

Clear transaction history and PIN-protected actions

Week 1: Discovery, research, and user pain-point mapping

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.

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.
