Circle Internet Group announced on Tuesday that an affiliate has formed a strategic partnership with Sasai Fintech, a subsidiary of Cassava Technologies, which counts Nvidia among its investors. The collaboration aims to significantly expand the reach of Circle's USDC stablecoin across Africa for business payments, cross-border remittances, and mobile wallet services.
USDC, a digital currency pegged to the U.S. dollar, is designed to maintain a stable value, with Circle guaranteeing holders the ability to redeem each token for one U.S. dollar. The partnership is strategically timed, following a period of substantial growth for the stablecoin. In the fourth quarter of 2025, the circulating supply of USDC jumped 72% compared to the same period a year earlier, reaching $75.3 billion. This surge helped drive Circle's revenue above market expectations, with Seaport Research Partners analyst Jeff Cantwell noting at the time that the token was "scaling rapidly."
Africa as a Key Market for Digital Finance
The African continent represents a critical testing ground for stablecoin adoption. A study conducted in February 2026 revealed that nearly 80% of survey respondents in Nigeria and South Africa already hold stablecoins. Industry experts point to systemic inefficiencies in traditional payment networks as a primary driver. Chris Harmse, co-founder of payments infrastructure firm BVNK, observed that people in the region frequently turn to digital dollar tokens when conventional systems prove "slow, expensive, or unreliable."
Circle stated that its collaboration with Sasai is focused on deploying USDC in practical, real-world financial applications. The goal is to drastically reduce costs, eliminate friction, and shorten settlement times for both Sasai's business clients and retail customers. Sasai's platform handles a range of services including business-to-business payments, individual cross-border transfers, remittance operator services, and mobile wallet offerings.
Strategic Vision and Previous Expansion
Cassava founder Strive Masiyiwa characterized Africa's digital economy as entering "a new era," while Circle CEO Jeremy Allaire identified the region as a "significant opportunity" for internet-native financial systems. This partnership is part of Circle's ongoing expansion across Africa. In April 2025, the company teamed with payments gateway Onafriq to pilot USDC-based remittance and settlement systems in more than 40 African countries. Separately, Sasai recently launched a remittance application focused on South Africa in collaboration with Western Union.
The competitive landscape for blockchain-based payments is intensifying beyond Africa. Payment giants Visa and Mastercard are aggressively pursuing their own stablecoin initiatives. Visa has begun testing USDC settlement capabilities with several U.S. financial institutions. Meanwhile, Mastercard has entered into an agreement to acquire BVNK, a stablecoin infrastructure provider, for up to $1.8 billion. Both companies are racing to establish early dominance in the emerging field of blockchain-driven cross-border payments.
Challenges to Mainstream Adoption
Despite this momentum, significant hurdles remain for integrating digital token rails into everyday commerce. In January 2026, Visa's head of cryptocurrency publicly acknowledged the persistent lack of broad merchant acceptance, stating that scalable solutions were not yet in place. Research cited by Boston Consulting Group (BCG) indicates that only about 6% of all stablecoin transactions are currently used for purchasing goods or services.
Regulatory scrutiny also presents a challenge, particularly in emerging markets. Authorities in some countries have expressed concerns that dollar-linked stablecoins could accelerate capital flight and deepen economic dollarization, potentially undermining local currencies and monetary policy.
Cassava Technologies disclosed last year that it had secured an investment from semiconductor leader Nvidia. For Circle, aligning with Sasai expands its network of African partners as financial technology firms globally seek to increase the speed and reduce the cost of international money movement.
