Nigeria received about $59 billion in crypto-asset inflows between July 2023 and June 2024, according to the latest recorded data from the International Monetary Fund (IMF). Yet Ethereum's public node tracker, Ethernodes, lists only about 28 nodes across the entire African continent, out of roughly 8,000 worldwide. Nodes are the computers that run a blockchain such as Ethereum. Running one lets its operator verify transactions against the blockchain's records directly, rather than relying on a third-party service.

African users are adopting the technology at speed, but establishing who runs the infrastructure beneath it is considerably harder.

Nigeria offers the clearest case. The country accounts for roughly 60% of Sub-Saharan Africa's stablecoin inflows since 2019, the IMF said in a June 16 report. The fund tied that demand to the naira's sharp fall, high inflation and limited access to foreign exchange during 2023 and 2024.

What sits underneath a USDT transfer?

Stablecoins such as Tether's USDT and Circle's USDC are tokens pegged to the US dollar. Sending one from a phone in Lagos or Nairobi engages several layers at once: the blockchain itself, the node that connects the wallet to it, the cloud servers hosting the app and the company that issued the token. A disruption at any of these layers can interrupt a transfer, which is why the identity of each operator matters.

Most applications do not run their own nodes. Ethereum's documentation notes that developers often rent access from providers such as Alchemy, Infura, QuickNode or Blockdaemon, which centralises part of any product built this way. The same documentation adds that switching providers is usually a one-line code change. Technext could not find public information on which providers African crypto firms use.

How many Ethereum nodes does Africa have?

Ethernodes lists about 28 execution-layer nodes across Africa, roughly 0.3% of the global total. South Africa leads with 13, followed by Mauritius with nine. Nigeria has four, all in Lagos, and only one was fully synced with the network as of October 9. Mali and Algeria have one each. Kenya, Egypt and Ghana do not appear at all.

By comparison, the United States hosts 2,398 nodes and Germany 1,109. On the consensus layer, whose nodes agree on which blocks are added, only South Africa (30) and Mauritius (11) appear, out of about 5,800 worldwide.

The tracker can miss nodes, and cloud hosting can obscure where one physically sits. The figures indicate where nodes appear to run, not who controls the network.

Crypto issuers sit abroad too

The IMF says widespread use of US dollar stablecoins can resemble digital dollarisation, warning that it could weaken the transmission of domestic monetary policy by reducing demand for the naira.

Tether is pushing into African distribution. It invested in Kenya-based Kotani Pay, which connects crypto users to local payment channels. It has also announced plans with Shiga, an Abu Dhabi-based fintech, to build self-custodial products for Africa and the Gulf Cooperation Council on Tether's open-source Wallet Development Kit.

Tether has not named any bank or fintech that has agreed to deploy Pulse, its institutional product, according to crypto.news.

African firms handle the last step

Stablecoins are only useful if people can swap them for local money. An on-ramp converts local currency into stablecoins, and an off-ramp converts them back. African companies mostly handle this step. Onafriq runs a payments network linking banks, mobile-money operators and merchants in more than 40 African markets.

Circle says Onafriq now settles in USDC through that network. Circle has a commercial relationship with Onafriq.

Kotani Pay, Yellow Card and Quidax perform similar work. None of them run Ethereum or issue USDT or USDC.

Who owns the buildings?

A June 2026 mapping by UK consultancy Data Landscapers traced 306 data centres across 46 Sub-Saharan countries to their ultimate owners. It classed 213, or 70%, as African-controlled. US-controlled operators ran 39, or 13%, mostly in South Africa, Nigeria and Kenya.

Hyperscalers, the large global cloud providers, were present in 112 of the 213 African-controlled facilities, a share of 53%.

The authors describe the work as a working analysis: it was compiled with AI tools and their own classification, and an April version reached the opposite conclusion.

In Nigeria, 21 of the country's 25 data centres are located in Lagos, according to Intelpoint, Techpoint Africa's research arm, writing in February 2026.

Can African firms switch?

The dataset's authors note that a building's owner is not the only party with influence. Tenants, lenders and equipment suppliers hold it as well.

Ethereum's documentation says node providers can be swapped in a line of code. Whether African firms can switch cloud contracts and stablecoin liquidity just as easily is not yet documented.
