In Africa, technological innovations often take on a different meaning driven by various interests and end results. In other parts of the world fintech innovations are anchored on high-speed, multifunctional apps and AI-driven finance, but what counts as real revolution in Africa, a continent of 1.5 billion people, might be happening through something as simple as a text message.

There are now innovations on SMS-based blockchain wallet, that is, transacting on a blockchain over basic text messaging. Textcash is developing one of such wallets and has launched on the Stellar Testnet. This is now game-changing solution for millions of Africans who hitherto remained excluded from the formal financial system but have access to small ubiquitous mobile phones.

There are a number of conditions that make this exciting and revolutionary at the same time. At least one in every three Africans are predicted to own a mobile phone in 2025 but access to the internet is quite limited. GSMA’s 2024 report revealed that while mobile penetration is strong, nearly half of Africa’s mobile users still rely on basic feature phones. The fintech sector’s assumption that innovation must be tied to smartphones has long alienated these populations.

That’s where SMS wallets come in. By leveraging blockchain technology on the backend while using SMS as the user interface, these wallets enable people to send, receive, and store money without needing an internet connection. The potential is massive.

Take rural Nigeria, for example. In communities where banks are absent and connectivity is patchy at best, an SMS wallet allows a farmer to receive payment for their produce instantly and securely. They don’t need middlemen. No one must trek for 10km to a banking hall. It only takes a phone and a few taps on a phone, and you get paidyou’re your services or send money to your loved ones.

Even more compelling is the promise of cross-border trade and remittances. African traders frequently operate across porous borders, from Lagos to Cotonou, from Accra to Lome, from Aba to Abidjan. Usually, moving money across these borders is expensive, slow, risky and tedious, requiring so many gatekeepers. But with blockchain-backed SMS wallets, we could witness a new era of affordable, instant remittances. The new innovative products will cut costs by more than 80% and empower informal trade networks that have for a long time prop up regional economies.

And then there’s humanitarian relief. Aid agencies have often struggled to deliver assistance efficiently to displaced populations who have no ID, no bank accounts, and no phones beyond basic feature models. With SMS wallets, digital cash assistance can be sent directly to beneficiaries with minimal fraud and overhead.

Critics might argue that security on feature phones is weak, or that blockchain is still poorly understood by the masses. They’re not wrong—but they are missing the bigger picture. Every transformative technology carries early-stage friction. What matters is whether the infrastructure exists to scale, and whether the need justifies the risk. Wallets delivered by textcash, for example, solve this problem by providing strong verification systems to ensure trust in the system.

In this case, the need couldn’t be clearer.

Africa doesn’t need to catch up with Silicon Valley. It needs solutions that work in its unique realities. SMS-based blockchain wallets are not just a workaround—they represent a radically inclusive model of financial technology. One that finally reaches the people fintech was supposed to serve in the first place.

If governments, telecom operators, and developers can rally around this innovation, we may finally see a future where every African, regardless of location or income, can access, control, and grow their own digital financial identity—starting with a text message.
