In Douala’s busy markets, a supplier’s next order depends on getting paid for the last one. Not long ago, a trader sending money across a border might have relied on a travelling relative, a trusted intermediary or a bank transfer that took days to clear. Today, digital payment services are changing that reality, allowing money to move across borders in seconds along supported payment routes.
The significance goes beyond speed. When a trader can pay a supplier on time, stock arrives sooner. When a freelancer receives an international payment and can access the money locally, distance becomes less of a barrier to earning a living. These are everyday transactions, but together they are changing how people work, trade and do business across Africa.
Grey is part of this shift, connecting international transfers with local financial systems, including mobile money in supported markets such as Cameroon. For users, the value is practical: paying a collaborator, restocking a shop or supporting family abroad without having to navigate the process alone.
Africa’s money-moving story has travelled from cash carried on buses to transfers initiated on a phone. Yet the digital economy presents an interesting contrast: information can cross the world almost instantly, but moving money still involves national borders, different currencies, regulations and financial networks. The next chapter is not simply about making payments faster. It is about making cross-border transactions work as naturally as the trade, work and family relationships that already connect the continent.
A brief history of money in Africa
Money has always moved across Africa, but the systems for moving it have rarely been simple.
For much of the continent's history, formal banking was concentrated in major cities and commercial centres. Large parts of the population operated outside the formal financial system, relying heavily on cash and informal networks to earn, save and transfer money.
Then there is the question of currency. Africa is home to more than 40 currencies, each operating within different monetary systems and financial regulations. Moving money between two African countries can involve currency conversion, intermediary banks and additional transaction fees. For example, Cameroon uses the Central African CFA franc (XAF), Côte d’Ivoire uses the West African CFA franc (XOF), while Rwanda uses the Rwandan franc (RWF). To make cross-border transactions easier, Grey has expanded into these markets, supporting regional currencies such as XAF and XOF and enabling users to move money across borders.
That fragmentation has had consequences for ordinary people as well as businesses. A family might have relatives living in another country. A trader might buy stock from across the border. Someone working in a city might earn their income hundreds of kilometres away from where their family lives.
How Africa found ways to move money across borders
As Africans moved across borders for work, trade and family, money had to follow. A trader in Lagos paying a supplier in Accra, for instance, could face currency conversion, intermediary banks and transfer fees before the money reached its destination. Historically, people relied on travelling relatives, traders and informal agents to bridge this gap.
Digital payments have changed how money moves, but sending money across African borders can still be costly and complicated. Grey helps simplify this process by enabling users to hold and exchange multiple currencies and make international transfers without relying on the traditional chain of intermediaries for every transaction. The goal is to make moving money across borders more accessible, convenient and transparent.
Mobile money, digital wallets and cross-border fintech
The arrival of mobile money changed the African financial landscape.
Mobile money has transformed financial access across Africa, and Kenya’s M-Pesa is one of its most successful examples. Launched in 2007, it allows people to send, receive and store money using their phones, with local agents providing cash-in and cash-out services. By March 2022, M-Pesa had reached 52.4 million customers across its African markets, processing more than 19 billion transactions that year. Its growth shows how mobile technology, agent networks and everyday payment services can bring financial services to people beyond traditional bank branches.
But sending money within Kenya is different from paying someone in another country. A freelancer in Nairobi paying a supplier in London or supporting family in Lagos needs a way to convert shillings and deliver the money to a foreign bank account. Grey lets users in Kenya fund their accounts through M-Pesa or a bank transfer and send money internationally. This includes Kenyan shillings to British pounds, euros to 30 European countries through SEPA, and Nigerian naira. SEPA, or the Single Euro Payments Area, is a payment network that standardises euro bank transfers across participating countries. Grey shows the exchange rate and fee before users confirm the transfer.
At the same time, infrastructure such as the Pan-African Payment and Settlement System (PAPSS), is being developed to make payments between African countries easier and reduce some of the dependence on international intermediary currencies.
The result is a financial system that looks increasingly different from the one that existed just two decades ago.
How sending money works in Nigeria, Ghana, Kenya, Rwanda and South Africa
There is no single African way of sending money.
In Nigeria, instant bank transfers have become part of everyday life. The country’s fintech industry has also created a large network of digital payment services and agent banking, making it possible to move between bank accounts, wallets and cash.
Kenya’s story is more closely associated with mobile money. M-Pesa became deeply embedded in everyday transactions, from sending money to family to paying businesses.
In Rwanda, services such as MTN MoMo allow people to send money, pay bills and make purchases using their phones. The country’s 2024 FinScope survey found that 86% of Rwandans had used mobile money, showing how widely these services have been adopted. For international transfers, Grey supports sending money to Rwanda, making it easier to move funds across borders.
Ghana has also embraced mobile money, with approximately 73 million registered accounts by the end of 2024. Its payment infrastructure allows users to transfer funds across different mobile money providers and bank accounts. Grey also supports transfers to Ghana, connecting international payments with local receiving methods.
In South Africa, where bank transfers are already part of everyday life, the next step is to make it easier to move money out of the country. Grey enables users to send and receive money internationally without relying solely on traditional banking channels.
A person sending money from Nigeria may be using a bank account. The recipient in Cameroon may be using MTN MoMo. Someone in Kenya may expect the money to arrive through M-Pesa.
For the payment to work smoothly, all those systems have to communicate.
Why sending money differs across African Markets
The differences are not accidental.
Each country has developed its payment ecosystem around its own regulations, infrastructure, economy and consumer behaviour.
Kenya’s mobile-money success was helped by an environment in which telecommunications companies could play a major role in financial services. Other markets have placed greater emphasis on commercial banks and licensed fintech companies.
Infrastructure also shapes behaviour. Where bank branches and formal financial services are easily accessible, consumers have more options. Where banking access is limited, mobile money agents can become a practical alternative.
Currency conditions matter too.
In countries experiencing significant currency volatility, people may look for ways to hold or receive money in stronger foreign currencies. For businesses operating across borders, access to foreign-currency accounts and efficient conversion can become particularly important.
This is why there cannot be a single solution for the entire continent. A payment product has to fit the market it enters, and increasingly, it also has to connect that market to others.
What sending money means in everyday African life
Behind all this infrastructure are very ordinary transactions.
A parent sends money to a child studying in another city. Someone working in construction sends part of their wages home. A trader pays a supplier. A family member abroad sends money to relatives. A small business receives payment from a customer in another country.
The amounts may vary enormously, but the importance of the transaction does not necessarily depend on its size. For someone running a market stall, a delayed payment can mean missing the chance to buy stock. For a family, it can mean waiting for money needed for food, transport or school fees. This is why the development of digital payments has been so significant. It is not simply making financial transactions faster. It is changing how people organise their economic lives across distance.
The future of cross-border payments: PAPSS, Grey and Francophone Africa
The next challenge is connecting all these systems.
Cameroon provides a useful example. Mobile-money services such as MTN MoMo and Orange Money have become important parts of the country's financial ecosystem. International remittance services can increasingly connect people outside Cameroon with recipients using these local wallets.
That creates a very different experience from the traditional bank wire. A recipient does not necessarily need a conventional bank account. Money can be deposited directly into the mobile wallet already used for everyday transactions. Grey is part of this emerging cross-border infrastructure, enabling supported users to send money to Cameroon via local payment networks, including MTN and Orange mobile money wallets.
One of the biggest challenges when moving money across Africa is that cross-border payments can be more complicated than they should be. A Nigerian business paying a supplier in Cameroon, for example, may face currency conversion requirements, intermediary banks, additional fees and delays, depending on the banks and payment route involved.
The Pan-African Payment and Settlement System (PAPSS), developed by Afreximbank in collaboration with the African Union, was created to address this problem. It connects participating banks and payment systems, allowing payments between African countries to be processed in local currencies without always routing them through third-party currencies such as the US dollar. PAPSS is expanding its network of participating countries and financial institutions to make cross-border payments easier and support trade under the African Continental Free Trade Area (AfCFTA). The goal is to make it easier for African businesses to buy and sell across borders without the cost and complexity of traditional international payment routes.
The significance of these developments goes beyond remittances. If money can move more easily between African countries, businesses can trade more easily. Freelancers can work for clients in other markets. Families can support relatives across borders. Traders can buy stock without relying on someone to physically carry cash. Africa’s payments story began with people finding ways to move money when formal systems could not do so easily.
It moved from cash carried by people, to money sent through mobile phones, to digital wallets and increasingly connected payment networks. The next stage is not simply about making transfers faster. It is about making the continent’s different financial systems work together.
And when that happens, sending money across Africa may finally become less about crossing borders, and more about simply moving money where it is needed.
