Four months in, and the numbers tell a story that even Grey's founders might not have fully anticipated.
Since launching its B2B payments platform on February 10, 2026, the Nigerian fintech has processed $61.4 million in cross-border transactions. But here's the twist: stablecoins—USDC and USDT, those blockchain-based dollar proxies once dismissed as speculative playthings—have become the dominant payment method on the platform. Not a growing category. Not a promising experiment. The largest rail, outpacing traditional fiat channels entirely.
For a payments infrastructure built to serve African startups and SMEs, that's more than a curiosity. It's a data point that suggests the ground is shifting beneath how emerging market businesses actually move money.
Grey CEO Idorenyin Obong unveiled the $61.4 million figure in early June, several months after the company introduced Grey Business at a side event during Africa Tech Summit Nairobi on February 10. The platform hasn't disclosed what percentage of that volume stablecoins represent—only that they've eclipsed conventional routes. Nigeria leads in transaction count; Western Europe and the Middle East in transaction value. The stablecoin dominance wasn't engineered. It emerged.
They Built Multi-Rail Infrastructure. Users Chose Crypto.
Grey Business was designed with optionality in mind. The platform offers USD corporate accounts complete with routing numbers, IBAN, and SWIFT codes for companies operating in emerging markets. Bulk CSV payouts reach over 170 countries through local bank transfers and mobile money networks. Real-time FX conversion sits alongside native USDC support. Customers could pick their preferred method.
And they picked stablecoins.
USDC deposits currently flow through BEP-20 and Solana networks, credited in real time once confirmed on-chain. USDT is also supported, though the platform has tweaked network offerings as the technology evolved. Help documentation updated in May and June 2026 now supports BEP-20 and Solana for USDC deposits, a reflection of shifting cost structures and transaction speeds in the blockchain world.
The workflow is straightforward: businesses deposit USDC, convert to USD if necessary, and disburse payments to vendors or contractors via local methods. Or they skip conversion altogether and send stablecoin-to-stablecoin. Grey's conversion fee page lists crypto pairs that include USDC and USDT alongside Bitcoin, Ethereum, Solana, BNB, and LINK.
Nothing exotic. Just practical infrastructure that happens to run on blockchain rails.
The Macro Context: A $205 Billion On-Chain Moment
Grey's traction didn't materialize in a vacuum. Sub-Saharan Africa recorded $205 billion in on-chain transaction volume between July 2024 and June 2025—a 52% year-over-year jump, according to Chainalysis. The blockchain analytics firm flagged frequent multi-million-dollar stablecoin transfers linked to trade flows and B2B cross-border activity, not the retail remittance use cases that once dominated the narrative.
Nigerian businesses, in particular, are operating in a foreign exchange minefield. In February, the Central Bank of Nigeria issued a warning that stablecoins could exacerbate FX volatility, citing ongoing improvements to the country's Payment System Vision framework. Yet a Techpoint Africa analysis from April found that USD-backed stablecoins are helping Nigerian companies manage cross-border risks more effectively than traditional banking channels can in environments where currency swings are both frequent and severe.
The regulatory stance, as the CBN's commentary on stablecoins indicates, remains in flux, not settled. Grey itself operates through dual entities: Grey Inc. in Delaware and Grey Finance Inc. in Canada, with FinCEN and FINTRAC registrations dating to September 2024, when the company crossed one million users. No updated user count has surfaced since—though the payment volume suggests growth, the company hasn't quantified it.
A Sector-Wide Pivot, Not an Outlier
Grey isn't running this play in isolation. Flutterwave announced stablecoin integrations in October 2025 and again in June, targeting cross-border merchant payments. Yellow Card, once a retail-focused crypto platform, shut down its consumer offering in late 2025 to pivot entirely to B2B stablecoin payments, later announcing a Mastercard partnership in May. Paga tapped the Sui blockchain network that same month for crypto payments and stablecoin yield products. Onafriq partnered with Conduit in February to enable stablecoin-powered treasury and cross-border settlement across the continent.
These aren't experimental add-ons tucked into a broader product suite. Multiple African fintechs are repositioning stablecoins as core infrastructure for business payments—not as a consumer remittance feature, but as the primary rails themselves.
The pattern is hard to ignore.
Product-Market Fit in Sixteen Weeks
Grey raised a $2 million seed round in August 2022 from Y Combinator, Soma Capital, Heirloom Fund, True Culture Fund, and a group of angel investors. Nearly four years later, the business line they launched in February has moved $61.4 million in four months, with stablecoins emerging as the preferred method—not through incentives or subsidies, but user choice.
The company hasn't shared customer counts, average transaction sizes, or customer acquisition costs specific to Grey Business. Those metrics would fill out the picture. But the payment mix itself tells a story most dashboards can't: when given a choice between USD corporate accounts, traditional foreign exchange services, and stablecoins, businesses in emerging markets are opting for crypto rails.
Speed, cost, control—perhaps all three. Or maybe something simpler: they work, and the alternatives increasingly don't.
The stablecoin adoption here isn't a sideshow. It's the headline.
