Mojaloop Foundation Powers Launch of NimbaPay: Guinea’s New National Instant Payment System

Guinea has launched NimbaPay, a national Inclusive Instant Payment System (IIPS) built on Mojaloop’s open-source infrastructure. This deployment marks Guinea as the 31st African nation to adopt a national instant payment system, offering fintech professionals a significant case study in how interoperable digital public infrastructure can drive financial inclusion and modernize sovereign financial systems.

What was announced

NimbaPay is Guinea’s new national payment rail, designed to facilitate secure, interoperable, and instant transactions. The platform connects a diverse range of financial participants, including the country’s commercial banks, e-money providers, and microfinance institutions. By utilizing Mojaloop’s open-source payment infrastructure, the system allows these disparate entities to exchange value in real-time, regardless of the specific provider used by the sender or receiver.

The platform officially went live on July 22, 2026. It is operated by La Guinéenne de Monétique (GuiM), the national payment switch operator, under the leadership of the Banque Centrale de la République de Guinée (BCRG). Technical implementation was handled by ThitsaWorks, with strategic and technical support provided by the AfricaNenda Foundation. Beyond providing the underlying technology, the Mojaloop Foundation conducted training for local technical service providers and systems integrators to manage the platform’s ongoing development.

Early performance data indicates rapid adoption following the launch. Between June and August 2026, NimbaPay processed 24,064 transactions with a total value of GNF 19.151 billion (approximately US$2.18 million). The growth trajectory is steep; transaction volume rose from 5,542 in July to 18,459 in August. Correspondingly, the value of those transactions jumped from GNF 2.584 billion (US$294,000) to GNF 16.567 billion (US$1.88 million). System reliability has remained high during this scaling phase, with over 99% of transactions processed automatically end-to-end and only 228 errors recorded during the initial period.

"NimbaPay is more than a new payment system, it is foundational digital public infrastructure that will enable the people and businesses of Guinea to move money instantly, securely and affordably. Our role has not only been to provide open-source technology, but to work alongside our partners to help Guinea bring to life its vision of a payment system that enables innovation, strengthens financial inclusion and expands economic participation."

The companies involved

The Mojaloop Foundation is a nonprofit organization dedicated to advancing financial inclusion through the development of open-source, interoperable payment systems. Its technology is designed to lower the barriers for emerging markets to build sovereign financial infrastructure. AfricaNenda, a key partner in the Guinea project, is an organization focused on accelerating the deployment of inclusive instant payment systems across the African continent to benefit the unbanked and underbanked populations.

The project was spearheaded by the Banque Centrale de la République de Guinée (BCRG), the nation's central bank, and La Guinéenne de Monétique (GuiM). GuiM serves as the national switch operator, managing the technical exchange between financial institutions. Aly Badara Bérété serves as the Managing Director of GuiM. This initiative places Guinea alongside regional peers like Rwanda and Liberia, which have also moved toward national instant payment frameworks to modernize their economies and reduce reliance on cash. The implementation was further supported by ThitsaWorks, which managed the system integration.

What FF News has reported before

FF News has closely followed the expansion of Mojaloop-based systems across the continent as central banks seek to modernize their domestic rails. In late 2025, we reported that the Central Bank of Liberia Launches Transformational Inclusive Instant Payments System (IIPS) Powered by Mojaloop, a move that mirrored Guinea's current strategy of using open-source tools for national infrastructure. More recently, we covered how Mastercard Partners with Mojaloop and AfricaNenda to Secure African Instant Payments, highlighting the growing interest from global private sector giants in supporting these nonprofit-led interoperability initiatives to ensure security and trust in emerging digital economies.

What this means

The launch of NimbaPay reinforces a growing trend where African central banks are opting for open-source "Digital Public Infrastructure" (DPI) over proprietary, vendor-locked solutions. By choosing Mojaloop, Guinea is asserting sovereign control over its financial rails, which puts traditional, high-fee international remittance and payment providers under pressure to justify their costs in an increasingly low-friction environment. The success of this model hinges on local technical capacity; while the initial transaction growth is impressive, the long-term challenge for the sector will be maintaining these systems without perpetual external support. This move signals to the market that interoperability between mobile money and traditional banking is no longer optional for national economic modernization.
