Stellar PULSO Hackathon

Introduction NearX and the Stellar Development Foundation present PULSO Hackathon, a 10-day fully online builder competition running simultaneously across Brazil, Argentina, and Colombia. Teams build on Stellar infrastructure, complete a minimum of 5 customer discovery interviews, and deploy on testnet. The top finalists from each country pitch live on July 6 in São Paulo, Buenos Aires, and Bogotá simultaneously. The top 3 winning teams per country earn a fully sponsored trip to São Paulo for Stellar House SP and the Stellar Summit immersion. PULSO is built for builders who are ready to ship. Timeline - Until June 20 - Applications open - June 21 - Hackathon begins - June 30 - Submission deadline - July 1 - Finalists announced (up to 10 per country) - July 6 - In-person pitch sessions · São Paulo · Buenos Aires · Bogotá - July 8 - Winners announced - Late July - Winner travels to São Paulo - July 30 / August 6 - Stellar Summit SP · 8-day immersion - August 6 - Stellar House SP Submission Requirements We're keeping requirements very balanced. To be eligible, your submission needs: 1. An open-source repo. A public GitHub, GitLab, or Bitbucket repository with your full source code and a clear README.md explaining what you built. The more detail, the better. 2. Integrations on Stellar. Your project should use integrations in a meaningful way and it should touch Stellar - for example, on/off-ramping values, or otherwise integrating the Stellar testnet or mainnet. The integration should be load-bearing: it powers a real part of how the project works, rather than appearing only on a slide. 3. A pitch-deck. A presentation for you to show the most relevant aspects of your project, such as the problem that you're solving, how your solution differs from others, and anything else you feel is relevant to highlight. Do something beautiful; you might need to pitch IRL. 4. A short demo video. A 1-2 minute walkthrough showing what you built. It doesn't need to be heavily technical or produced, just clearly show the prototype working and explain which real-world problem you're solving with it. You do not have to be in the video. That's it. No exhaustive mandatory framework, no bounty to apply for, no specific track to fit into (rather than the local track). Just build something amazing. Prizes 1st. Place: Instawards + fully sponsored trip to São Paulo 2nd. Place: Instawards + fully sponsored trip to São Paulo 3rd.

Mainnet deployment or live traction is a scoring advantage. Contact us https://t.me/+nR071cZP3LY2OGQx About us NearX is a builder-focused innovation organization operating across Latin America.
