The ETHAccra Hackathon brings together the Ethereum community of developers to compete and build innovative projects using the Ethereum blockchain and connecting the blockchain technology to real use cases.
Everyone is able to apply to be a hacker but the organisation will manually select and curate the candidates. Entries for all hackers will be free of charge.
Bringing together developers and builders from diverse backgrounds, the hackathon will encourage the creation of new applications that can help address local problems in West Africa and advance the Ethereum community in West Africa.
The scope of this hackathon is to build and present projects that can have impact in real use cases.
The hackathon will be “Open Track”, there are no “predefined” themes, but every project should be related to the Ethereum ecosystem.

🎨 Culture, Creativity & Community
Description: Ethereum is more than finance — it’s a canvas for culture, creativity, and community-building. This track challenges hackers to design NFTs, DAOs, and creative platforms that capture the richness of African art, music, and traditions while enabling communities to thrive. The goal is to empower creators, preserve culture, and unlock new models of collective ownership.
🎯 Focus: NFTs, DAOs, gaming, music, and digital identity rooted in African culture.
🏆 Prize:
🥇 1st: $500
🥈 2nd: $500
📝 Qualification Requirements: Culture, Creativity & Community
🥇 1st: $2,000
🥈 2nd: $1,000
🎁 Builder Pool: $1,800 (shared among other eligible projects)
Africa is pioneering new models for digital identity, payments, and community coordination. Show how ENS can power the next generation of decentralized applications for both local and global communities.
Looking for creative ENS integrations that go beyond simple name resolution, including:
Identity & Reputation: portable digital identity, verifiable credentials in text records, community attestations, community subnames
