Sarah Wahinya, the Stellar Development Foundation's East Africa Lead, gave a candid account of how blockchain technology is actually being used across Kenya and Nigeria in an interview published May 8, 2026, by TechCabal. Speaking from her position at the intersection of regional partnerships, market expansion, and developer ecosystems, Wahinya described a continent where crypto adoption is being driven by concrete financial problems, not market cycles.

"Africa didn't adopt Web3 because it was trendy," she said. "We adopted it because the existing system was failing us."

Her examples are specific and verifiable. Kenyan freelancers are settling cross-border invoices in USDC (a dollar-pegged stablecoin) to avoid the banking delays built into traditional bank transfers. Nigerian traders are holding stablecoins as a hedge against naira volatility. Ethiopia saw 180 percent year-over-year growth in retail stablecoin transfers in 2025, a surge directly linked to a 30 percent devaluation of the local currency, a pattern that underscores the same underlying pressure driving adoption across the continent. These are not edge cases. Kenya ranks fifth globally in stablecoin transactional use, according to Transak's 2026 Africa Fintech Report, and Nigeria accounts for roughly 40 percent of continental stablecoin inflows. The same report found that stablecoins now represent 43 percent of all crypto transactions across Sub-Saharan Africa.

The underlying cost problem is substantial. A standard $200 remittance sent to Africa through conventional channels costs around 7.9 percent on average. Stablecoin rails have brought that figure closer to 2 percent in documented pilots, a reduction that matters significantly given Africa received $54 billion in remittances in 2023, according to Transak's 2026 Africa Fintech Report. Routing inefficiencies compound the issue: approximately 80 percent of intra-African payments are still processed through banks located outside the continent, generating an estimated $5 billion in avoidable annual fees.

Stellar has been building payment infrastructure across the region for several years. Its network currently supports Cowrie Integrated Systems, which routes dollar payouts into Nigerian bank accounts via USDC, and ClickPesa, which issues Kenyan and Tanzanian shilling representations directly on the Stellar ledger. Flutterwave and Tempo use Stellar-based USDC rails for Europe-to-Africa remittance corridors. The network has also backed companies including ChipperCash, Yellowcard, Kredete, and Cedar through its investment portfolio. Stellar's own 2025 annual review reported more than 10 million active accounts, 21.5 billion total operations since launch, and growth of 31 percent in full-time developers, a pace three times faster than the industry average.

As of May 8, XLM (Stellar's native token) was trading at approximately $0.16 with a market capitalization near $5.32 billion, ranking 22nd among all crypto assets by CoinGecko's measure. The network's total value locked grew 95 percent in 2025 to surpass $211 million, and tokenized real-world assets on Stellar exceeded $1.2 billion, including a $496 million position held by Franklin Templeton's BENJI token.

Wahinya also founded and runs the #WomenInDeFi Community, a mentorship network focused on career development for women working across African Web3 sectors. She described guiding a mentee from a position of self-doubt through to a leadership role in a protocol community, a reminder that the human infrastructure behind blockchain adoption requires as much deliberate investment as the technical kind. She is direct about the personal costs of working in an industry that operates around the clock: "Crypto's 24/7 nature demands constant availability. I sacrificed rest and boundaries. I'm actively relearning their importance."

On what constitutes real growth in her ecosystem, Wahinya draws a firm line. Token incentive campaigns may generate brief spikes in user numbers, but she argues that retention and developer engagement are the only metrics worth tracking if a protocol intends to build durable infrastructure.

That framing fits the timeline Stellar is now operating under. Ten days before Wahinya's interview was published, the Stellar Development Foundation announced a joint accelerator with CV Labs targeting EMEA-region startups. The program will fund up to 10 early-stage teams working in payments, tokenized real-world assets, and decentralized finance, with grants of up to $150,000 in XLM per team and an in-person component scheduled in Cape Town, South Africa, in August 2026. The foundation has set a 2026 target of $1 billion in network asset value growth and plans to sign 15 new enterprise partners and deploy at least 5 during the year.

Kenya's passage of the Virtual Asset Service Providers Act in October 2025 has added a layer of regulatory clarity that was absent as recently as 12 months ago. For developers and startups building payment tools in East Africa, that legal framework now provides a compliance pathway that makes the accelerator opportunity more actionable. Wahinya has spent years navigating the conditions that define this region: high remittance costs, currency instability, and infrastructure gaps that are unlikely to resolve quickly. Her position, shaped by that experience, is straightforward. Lasting adoption is built through retention and developer commitment, and in her view, those are the only metrics that have ever actually counted.
