The Hashgraph Association, a Swiss based non profit advancing digital enablement, innovation, and education across the Hedera ecosystem, and Exponential Science, an organization focused on supporting emerging technologies to advance human progress, have announced the winners of its Hedera Africa Hackathon, which has officially become the largest hackathon globally.

More than 13,000 developers, 1,300 project submissions, and 45,000 certification participants across 20+ African hubs participated in the Hedera Africa Hackathon.

The winning projects focused on building real infrastructure projects on top of Hedera Technology. These solutions included route payments across incompatible networks, verified renewable energy certificates, and secure medical records against silent or unauthorized alteration.

The $1 million prize pool, among the largest ever awarded at a Web3 hackathon, co funded by The Hashgraph Association, and Exponential Science, was distributed across four thematic tracks, alongside a cross-track championship recognizing the strongest projects overall. In addition to the success of the hackathon, The Hashgraph Association also formed an Investment Committee, which will make multi-million-dollar commitments in strategic partnerships, expanding the ecosystem’s global footprint and emphasis on emerging markets. This committee positions Hedera as one of the few ecosystems directly supporting builders with capital, mentorship, and enterprise pathways.
