04 / FAQ
Before you get started
Who can enter?
Developers aged 18 or over residing in Cameroon, with a MeSomb developer account. One project per person; up to three people per team. Organizers and evaluators cannot enter.
Can I use an existing application?
Yes. Integrate MeSomb into an existing product or build a new solution. Both tracks use the same evaluation criteria.
Do I need to make a real payment?
No. A working integration in an authorized test environment is sufficient. Entry is free and no purchase is required.
How does XP work?
Eight missions offer up to 1,000 XP per project, worth 25 points. Evidence must be validated. Social media likes do not earn extra XP.
How are finalists selected?
Projects need a working integration, successful technical checks and at least 36 out of 60 jury points. The five best qualifying projects advance to the final.
Must I publish my code?
No. A public repository is optional. You retain ownership of your project and source code. A private demonstration may be requested.
How are prizes paid?
100,000 FCFA for first place and 50,000 FCFA for second, through MTN Mobile Money or Orange Money. Hachther covers transfer fees. Payment is planned by January 18, 2027, subject to the official rules.
