ETHAccra Hackathon 2025

⚡ETHAccra Hackathon 2025⚡

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.

⚡Audience⚡

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.

⚡Scope⚡️      

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.
