Sub-Saharan Africa Moved $205 Billion in Crypto Last Year. Circle Is Finally Paying Attention.
Sub-Saharan Africa processed $205 billion in on-chain transactions in the 12 months to June 2025, per Chainalysis. Nigeria alone accounted for $92 billion of that. Crypto adoption in the region grew 52% in the same period — the fastest rate of any major geography globally. And USDC barely shows up in any of it.
That's the context for Circle's partnership with Sasai, a Pan-African payment platform owned by Cassava Technologies. Announced March 24, the deal will integrate USDC into Sasai's existing payment infrastructure across Nigeria, South Africa, Kenya, Ethiopia, and Ghana. Circle CEO Jeremy Allaire described it as targeting "high-growth payment corridors in emerging markets."
The USDT Problem Nobody's Mentioning
Africa's stablecoin story is almost entirely a USDT story. Tether dominates the continent's stablecoin usage — not because of any particular strategic push into Africa, but because USDT has been on Tron since 2019, with near-zero transaction fees. A $200 USDT transfer on Tron costs under a dollar. That product-market fit drove adoption years before any of the major Western stablecoin companies were paying attention to African markets.
USDC, by contrast, started life on Ethereum — expensive, slow, and inaccessible for people who can't absorb gas fees. Circle has pushed hard onto Base and Solana, which improves the cost picture. But the network effects in African markets were built by USDT on Tron, and behavioral inertia in payment habits is real.
What Sasai Actually Is
Sasai isn't a crypto company. It's a super-app with existing payment infrastructure in multiple African markets, owned by Cassava Technologies. Cassava's chairman is Strive Masiyiwa — a Zimbabwe-born entrepreneur who built Econet Wireless into a Pan-African telecoms group before it existed as a category. Sasai already moves money across African borders through its platform. Adding USDC rails is an extension of existing infrastructure, not a pivot into crypto from nowhere.
That makes this more credible than a typical "expanding to Africa" press release. Sasai has distribution. Circle has the dollar peg. Ghana's Financial Intelligence Centre approved 11 crypto platforms for its regulatory sandbox in March 2026. Nigeria reversed its blanket crypto restrictions in 2024. The regulatory window for compliant stablecoin use in these markets is opening.
The Remittance Math
Remittance costs into Sierra Leone, Uganda, and Angola exceed 7% per transaction — more than double the United Nations' 3% target. On a $200 transfer, that's $14 going to intermediaries rather than a family. If USDC through Sasai delivers the same transaction at $4, that's a real improvement for households where the margin is thin.
Whether it gets there depends on details the announcement doesn't provide: Sasai's active user count, specific USDC pricing, and the timeline for actual deployment. Partnership announcements are not launched products. Circle announced a USDC integration with MoneyGram in 2023; MoneyGram's off-ramp volumes never matched the press release's ambition. Africa's stablecoin users will decide whether this one is different.
