9 Women in Crypto and DeFi Making Their Mark on Africa’s Digital Finance 

For years, the cryptocurrency industry was associated with technical jargon, unfamiliar technology, and a largely male-dominated culture. But across Africa, a growing number of women are now helping shape what the sector becomes next, building careers in an industry that once seemed difficult to enter.

Women are taking on roles far beyond simply using or investing in digital assets. They are founding companies, developing blockchain technology, building communities, contributing to regulation, educating new users and helping create the infrastructure supporting Africa’s digital-asset economy.

Crypto describes digital assets that rely on blockchain networks to record and verify transactions. At the same time, decentralised finance, or DeFi, uses blockchain technology to provide financial services such as lending, trading and payments without depending entirely on traditional financial intermediaries.

What makes this shift particularly notable is not merely the growing number of women entering crypto. It is the diversity of positions they now occupy and the different ways they are influencing the industry’s direction.

Here are nine women worth knowing.

1. Sarah Idahosa — Founder, Women in DeFi

Idahosa founded Women in DeFi, a pan-African organisation focused on education, mentorship and access for women entering blockchain and decentralised finance.

The organisation says its work has reached thousands of women, while Idahosa also works with MANSA, a DeFi liquidity platform.

2. Ruth Iselema — Co-founder and CEO, Bitmama

Iselema founded Bitmama in 2019, building a crypto and blockchain payments company that grew from a community on WhatsApp into a platform serving users across African and international markets.

Her work sits at the intersection of cryptocurrency, payments, and cross-border finance.

3. Oluchi Enebeli — Founder, Web3 Ladies

Enebeli is one of Nigeria’s early female blockchain engineers and the founder of Web3 Ladies, a community created to help African women develop technical skills for Web3.

She also co-founded Crevatal and has worked with companies including Binance, Crypto.com, and Bundle.

For Enebeli, the issue was never simply getting women interested in blockchain. It was giving them the skills and community to actually build in it.

4. Faith Obafemi — Emerging Technology Lawyer

Obafemi works at the intersection of law, blockchain, cryptocurrency, and emerging technology. Her work focuses on helping organisations navigate the regulatory and compliance questions surrounding technologies that often move faster than legislation.

That role matters because crypto cannot exist on technology alone. Someone still has to figure out what happens when innovation meets the law.

5. Deborah Ojengbede — Founder and CEO, AFEN

Ojengbede brought experience from traditional banking into blockchain, where she leads AFEN, a Web3 infrastructure company focused on financial inclusion and decentralised technology.

AFEN describes its mission as expanding the practical use of Web3 and DeFi across Africa.

6. Doris Ojuederie — Founder, Blockchain Africa Ladies

Ojuederie founded Blockchain Africa Ladies, a community focused on helping women understand and participate in blockchain technology.

Her approach has centred heavily on education and practical skills, making complicated technology easier for newcomers to approach.

7. Olayinka Odeniran — Founder, Black Women Blockchain Council

Odeniran founded the Black Women Blockchain Council to create opportunities for Black women pursuing careers and businesses in blockchain and fintech.

With a background in compliance, cybersecurity, and financial services, she brings another perspective to an industry that needs both technical innovation and stronger institutional participation.

8. Alakanani Itireleng — “The Bitcoin Lady”

Based in Botswana, Itireleng became known as “The Bitcoin Lady” through her work educating people about Bitcoin and encouraging broader understanding of cryptocurrency.

Her story is a reminder that adoption is not only about building protocols; sometimes it begins with someone patiently explaining what the technology means to ordinary people.

9. Sonya Kuhnel — Co-founder, Bitcoin Events

In South Africa, Kuhnel co-founded Bitcoin Events in 2014, helping create platforms for blockchain and cryptocurrency education across the continent.

The organisation went on to host Blockchain Africa Conferences and Crypto Fest, while Kuhnel also founded the Blockchain Academy to provide training in blockchain and cryptocurrency.

The Bigger Story Is Bigger Than Crypto

Put these women together and an interesting picture appears.

One is building an exchange. Another is writing code. Another is thinking about regulation. Others are teaching, organising communities, developing infrastructure or creating spaces where the next generation can enter the industry.

That diversity of roles may be more important than the technology itself.

Africa's digital-finance future will not be shaped only by the people who write protocols or launch tokens. It will also be shaped by the people who explain the technology, regulate it, build businesses around it, and make room for others to participate.

And perhaps that is the real story behind these nine women.

They are not simply finding a place inside crypto. They are helping decide what that place looks like.
