Africa’s Stablecoin Infrastructure Problem is Not Adoption — It’s Rails

The story that has been told about stablecoins in Africa for the last three years is the story of a chart. It goes up and to the right. Sub-Saharan Africa received over $205 billion in on-chain crypto value between July 2024 and June 2025, a 52 percent year-on-year jump. Nigeria alone received $92.1 billion, nearly three times the total of second-place South Africa. Stablecoins now account for approximately 43 percent of Sub-Saharan Africa’s total crypto transaction volume. The numbers are real, and they are reported faithfully every quarter, and they have produced an industry-wide consensus that the African stablecoin opportunity is fundamentally a story about consumer adoption catching up to a product that finally works.

It is not.

The adoption is already here. The infrastructure underneath it is what isn’t. And the gap between the two — the gap between what users are doing on* stablecoin rails* and what the rails themselves can actually carry — is now the single most consequential bottleneck in African on-chain finance. Most strategic capital being deployed into the space is being deployed against the wrong problem.

Has stablecoin adoption in Africa happened yet?

Yes. Adoption has already happened, and the numbers say so without ambiguity. Sub-Saharan Africa took in over $205 billion in on-chain volume between July 2024 and June 2025, stablecoins are 43 percent of that volume, and the IMF estimates regional usage at 6.7 percent of GDP — one of the highest rates globally.

It is worth being precise about what the data is saying. The growth in African stablecoin volume between 2023 and 2025 is not a forecast. It is a record. In March 2025 alone, monthly on-chain volume in Sub-Saharan Africa reached nearly $25 billion, a clear outlier during a month when most other regions experienced declines. That spike was driven by a specific event — a naira devaluation in early 2025 that pushed Nigerian users into dollar-pegged assets at speed — but the structural story sits underneath the spike. Stablecoin behavior in the region is increasingly tied to high-value transactions linked to trade flows between Africa, the Middle East, and Asia.

That is not retail speculation. That is B2B settlement happening on rails that nobody designed for B2B settlement.

The global pattern around it is consistent. B2B stablecoin payments rose 733 percent year-over-year and now account for roughly 60 percent of global stablecoin payment volume. Monthly B2B stablecoin volume rose from under $100 million in early 2023 to over $6 billion by mid-2025. The IMF, in a 2025 Working Paper, estimated that stablecoin usage across Africa and the Middle East represented approximately 6.7 percent of total regional GDP in 2024 — one of the highest adoption rates globally.

When usage reaches 6.7 percent of GDP, the conversation about whether people will use the thing is over. The interesting question, the one strategic capital should be asking, is what is carrying that volume — and whether it can carry the next ten times of it.

What sits beneath the wallet layer in African stablecoin infrastructure?
A stack of custody, key management, policy, and compliance components that almost every African fintech has assembled internally because mid-market infrastructure for them has not existed. Consumer-facing companies sit on top of this layer. The layer itself is largely unbuilt as a market.

What is carrying African stablecoin volume today is a mix of consumer exchanges, on-and-off-ramp providers, and a handful of payment-layer fintechs that have stitched together correspondent relationships, custodial wallets, and bilateral integrations into something resembling rails. Companies like Yellow Card, Flutterwave, and Onafriq joined Circle’s new Payments Network in 2025 as design partners, bringing critical on-and-off-ramp infrastructure and access to over 500 million mobile wallets to the network. Flutterwave’s CEO told the World Economic Forum in early 2026 that the company is now building stablecoin rails on top of its existing fiat infrastructure, citing B2B payment costs as low as 0.5 percent on stablecoin rails compared with 1.5 percent on traditional ones.

This is real, and it works, and it is also not the bottom of the stack.
What sits beneath Yellow Card, Flutterwave, Onafriq, and the dozen smaller payment-layer companies operating in the region is a custody, key management, policy, and compliance layer that, in almost every case, has been assembled internally — by engineering teams who would much rather have been building product. The wallet is the visible part. The thing that signs the transaction, holds the key shards, applies the policy, screens the counterparty, records the audit trail, and survives the security review is the invisible part. And in Africa specifically, the invisible part is what has been holding the consumer-facing growth together with engineering effort that does not scale.

This is the layer that the industry has not built. It is also the layer that determines whether the next phase of growth happens at all.

Why is correspondent banking no longer a viable fallback for African payments?

Because the global banks that anchored it are leaving. Active correspondent banking relationships have declined 22 percent worldwide since 2011, and Barclays, Standard Chartered, Société Générale, and BNP Paribas have each exited major African corridors between 2022 and 2026.

The reason this matters now, and did not matter as urgently three years ago, is that the alternative — the correspondent banking system that Africa-to-the-world payments have run on for fifty years — is in a state of measurable retreat. The number of active correspondent banking relationships worldwide has declined by 22 percent since 2011, with the country-level declines ranging from 23 percent in advanced economies to 41 percent in small island developing states. The retreat from Africa in particular is documented and ongoing. Barclays completed its century-long African exit in 2022. Standard Chartered divested across Angola, Cameroon, Gambia, Sierra Leone, and Zimbabwe between 2022 and 2025, and confirmed a full exit from Botswana in early 2026. Société Générale divested its Moroccan and Algerian interests in 2024–2025, and BNP Paribas shut down its South African investment arm in 2024.

This is the kind of cost that is easy to absorb because it has always been there, until suddenly it isn’t. The ECB has noted that average remittance costs to Sub-Saharan Africa remain at 7.7 percent, with the global Sustainable Development Goal target of 3 percent still far from being met. The CEPR has shown, using firm-level data, that when a firm’s main bank loses a correspondent relationship, the probability of exporting falls by 9.7 percentage points on average, and small firms see total exports decline by 42.7 percent.

What this means in practice is that for a growing portion of African

trade, the question is no longer whether stablecoin rails are better than correspondent banking. The question is whether they are available in the corridor at all. Where they are, businesses use them. Where they aren’t, businesses lose export volume.

What does “building the rails” mean in concrete terms?

It means owning six distinct layers — consumer interface, payment orchestration, custody, policy engine, compliance, and settlement network. In Africa, the top two layers have credible vendors. The middle three have almost none, which is the mid-market gap.

The term “rails” gets used loosely in this conversation, so it is worth being specific about what is on the list and who is responsible for each layer.

Every African fintech serious about stablecoin volume has had to assemble the middle three layers — custody, policy, compliance — internally, because the existing options were built for a different market. Fireblocks was built for institutional desks in New York and London with four-month integration cycles and seven-figure annual contracts. Privy, now part of Stripe, was built for consumer-facing Web3 apps that did not need a policy engine or institutional-grade compliance. Both work for what they were built for. Neither was built for a Series B Nigerian fintech with a CFO watching the burn and a CISO with a SOC 2 audit on the calendar.

This is the mid-market gap, and in Africa it is not a gap in features — it is a gap in whether the rails exist at all for the companies trying to use them.

Why is most stablecoin capital going to the wrong layer of the stack?

Because consumer-facing companies are legible to fintech investors and infrastructure companies are not. Wallets and on-ramps pattern-match to mobile money. The custody-policy-compliance layer beneath them looks like enterprise sales, which is harder to underwrite — so it gets underfunded.

The fundraising data shows where the industry’s attention is. Most African stablecoin-adjacent capital in the last twenty-four months has flowed to consumer-facing on-and-off-ramps and to payment orchestrators sitting one layer above the rails. Both are valuable. Neither is the bottleneck.

The reason is partly that consumer-facing companies are legible to investors who came up in fintech and pattern-match stablecoins to mobile money. The chart on the slide is volume, and the volume is real, and the company telling the story is the one the user opens on their phone. Infrastructure companies — the ones building the layer below the layer everyone else is looking at — are harder to underwrite because their customers are other companies and their growth looks like enterprise sales rather than user acquisition.

This is the familiar pattern of infrastructure markets. The companies that get funded first are the ones building the visible parts. The companies that get funded next are the ones building the parts that turned out to be load-bearing. Stripe is now worth what it is worth not because it built a checkout button — many companies built a checkout button — but because it built the unglamorous layer beneath, the part where compliance, routing, fraud detection, and reconciliation happen.

Africa’s stablecoin infrastructure is currently in the first phase of that cycle. The checkout-button equivalents — the wallets, the on-ramps, the orchestrators — have been built and are growing. The Stripe-equivalent layer — the configurable, compliant, programmable rails that everything else depends on — has not.

What changes for African stablecoin builders in the next eighteen months?

Three forces converge: demand keeps growing, the GENIUS Act and MiCA harden compliance requirements, and Visa and Mastercard move stablecoins into core settlement. Fintechs whose rails are already production-grade survive the shift. Fintechs whose rails were assembled in a sprint will not.

Three things are now true at the same time, and the convergence is what makes this moment different from the moment a year ago.

First, the demand is real and growing. The 52 percent year-on-year growth in Sub-Saharan African on-chain volume is not driven by speculation; it is driven by Nigerian fintechs replacing correspondent banking, by Kenyan logistics companies paying trucking partners daily, by Ghanaian agricultural businesses receiving payment from European buyers on shipment confirmation. The use cases are mundane, which is exactly what makes them durable.

Second, the regulatory frame is solidifying. The GENIUS Act in the United States, MiCA in Europe, and the Virtual Asset Service Provider regimes now being implemented across Ghana, Nigeria, South Africa, and Kenya are converging on a model that treats stablecoins as regulated payment infrastructure rather than as crypto-adjacent assets. The GENIUS Act requires stablecoins to be fully backed by liquid assets and mandates regular public disclosures of reserves; in the UK and Hong Kong, issuers face increasingly strict transparency and audit requirements. This is good news for fintechs building on stablecoin rails — but only if the rails they build on can produce the audit trails, sanctions screening, and Travel Rule compliance the regulation demands. Most internally-assembled stacks cannot.

Third, the institutional players have stopped waiting. On March 3, 2026, Visa and Bridge announced an expansion of their stablecoin-linked card program to over 100 countries; SoFi and Mastercard partnered to allow the SoFiUSD stablecoin to be used for settlement across Mastercard’s global network. Yellow Card’s partnership with Mastercard, announced in 2026 and piloting across Ghana, Kenya, Nigeria, South Africa, and the UAE, is the African expression of the same shift. When Visa and Mastercard — networks that together process over $14 trillion annually — start integrating stablecoins into core settlement, the question for every other player in the system becomes whether their infrastructure can keep up.

The fintechs that win the next eighteen months in Africa will be the ones whose rails are already production-grade when the volume arrives. The ones whose rails were assembled in a sprint will spend the next eighteen months trying to refactor while shipping, and most of them will not make it.

What question should replace the adoption question?

What does the layer beneath the wallet need to look like to carry what the people are already doing? It is a more technical question, and a less marketable one, and it is the question whose answer will determine which African fintechs are still operating at scale in 2030.

The question that has driven African stablecoin strategy for three years is: how do we get more people to use stablecoins?

That question has been answered by the market. The people are using them.

This is on-chain finance — the category Tresori is building infrastructure for — and the African opportunity inside it is no longer about persuading users to adopt the rails. It is about whether the rails will be built in time.

For founders and engineering leaders evaluating where to spend the next twelve months, the practical move is to look at the layer beneath the wallet you are building, and ask whether you assembled it because you wanted to or because nothing else was available. If the answer is the second one, the on-chain finance infrastructure layer is now the thing worth evaluating.
