Mojaloop Foundation's Open-Source Technology Powers Launch of NimbaPay, Guinea's National Instant Payment System

Guinea joins a growing community of African nations now running interoperable, inclusive instant payments based on Mojaloop’s software infrastructure

WAKEFIELD, Mass.--(BUSINESS WIRE)--The Mojaloop Foundation, a nonprofit advancing financial inclusion through open-source interoperable, instant payment systems, today announced that its technology has been implemented in Guinea to power NimbaPay, the country’s national Inclusive Instant Payment System (IIPS).

NimbaPay is built on Mojaloop's open-source payment infrastructure and enables secure, interoperable instant payments between Guinea's participating banks, e-money providers, and microfinance institutions.

In addition to providing the technology underpinning NimbaPay's payment rails, Mojaloop also provided training for Guinea's local technical service providers, including the systems integrators now supporting the platform's ongoing operation and development. The Foundation also participated in the stakeholder engagement that helped build consensus around the initiative, working alongside AfricaNenda, Banque Centrale de la République de Guinée (BCRG), GuiM and Guinea's participating financial institutions. According to AfricaNenda's 2025 State of Instant and Inclusive Payment Systems (SIIPS) report, Guinea becomes the 31st African nation to operate a national instant payment system, joining a growing regional movement that includes Rwanda and Liberia.

Jean Bosco Iyacu, Chief Executive Officer, Mojaloop Foundation, said: "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.”

Dr. Karamo KABA, Governor of the Central Bank of the Republic of Guinea, said: “The launch of NimbaPay is a major milestone in the development of Guinea’s national payments infrastructure. As a sovereign platform, it will strengthen our control over critical financial infrastructure, support secure and efficient everyday transactions, enable businesses to operate more effectively and advance the modernization of our economy. Its impact will extend well beyond today, providing a foundation for Guinea’s economic development for decades to come.”

NimbaPay went live on 22nd July 2026 under the leadership of “La Banque Centrale de la République de Guinée (BCRG)” and “La Guinéenne de Monétique (GuiM),” the national payment switch operator, with strategic and technical support from the AfricaNenda Foundation and system implementation by ThitsaWorks.

Since going live, NimbaPay has seen a rapid growth in usage, processing 24,064 transactions worth GNF 19.151 billion (approximately US$2.18 million) between June and August 2026. Transaction volumes increased from 5,542 in July to 18,459 in August, while transaction value rose from GNF 2.584 billion (US$294,000) to GNF 16.567 billion (US$1.88 million). More than 99% of transactions were processed automatically end-to-end, with just 228 errors recorded across the period demonstrating the platform’s ability to support rapidly growing transaction volumes efficiently and reliably as adoption scales.

The initiative benefited from explicit government backing throughout: BCRG First Vice-Governor Elhadj Mohamed Lamine Conté, who also chairs GuiM's Board of Directors, chaired the project's steering committee under the oversight of BCRG Governor Dr. Karamo KABA, while Aly Badara Bérété, Director General of GuiM, provided operational leadership. The deployment moved from initiation to go-live in six months.

Steve Haley, Global Director, Ecosystem and Adoption, Mojaloop Foundation, added: “Collaboration has been the key to NimbaPay’s successful implementation. From the government champions who backed the vision publicly, to the technical teams managing the integration, it is this shared commitment that turns an open-source technology into a live national payment system. Collaboration only moves forward with strong and capable leadership, however, and Aly Badara Bérété has been a relentless changemaker for his country.”

Looking ahead, GuiM and its partners plan to scale NimbaPay, and are already moving forward with additional use cases, while Mojaloop Foundation continues to support the growth of local technical capacity in Guinea.
