Hacker essentials

Venue

Warehouse ONE16, Marvila, Lisbon. ONE16.

Search “Warehouse ONE16” in Google Maps — not the street address. The street address can send you to the wrong place.

From the airport: about 15 minutes by Bolt or Uber.

Prizes

$30,000 across 6 winners.

Prize amounts are denominated in USD and paid in the equivalent value of XLM.

Prizes are awarded on merit. Judges score every project using the criteria in the Judging section.

How to submit

Hacking ends at 12:00 on Mon 26 Oct. That is the submission deadline. No late submissions. Then judging.

A clear README that shows how your project works, including its specs, does most of the work for judges.

You own what you build. Submissions and IP.

Rules and AI

Behave professionally and respectfully. Follow the event rules, schedules, and venue requirements. Do not harass, cheat, plagiarize, or misrepresent your work.

Participation and code of conduct. It applies to everyone at the event.

AI-assisted development is allowed.

Two paths

Genesis

Start something.

For builders turning a new idea, early prototype, or problem worth solving into a working product.

Idea → MVP

Scale

Take it further.

For experienced builders, founders, and teams ready to move an existing product or ambitious concept toward production.

Prototype → Product

Tracks on the Genesis path

These tracks belong to the Genesis path. Genesis builders can be part of both. Scale projects don’t need to pick a track.

Stellar Unlocked

Your project gets something new out of Stellar's core protocol features.

Stellar Composed

Your project combines two or more ecosystem tools or projects into something new.

Judging

How projects are judged.

How judging works: async review of the demo video, pitch deck, GitHub repo, and submission answers. Live pitches are only for finalists, on Wed Oct 28.

Judging priority order: Adoption → Discovery → Continuation.

One rubric scores every project. Each criterion is scored 1–5. Genesis is scored on Track Alignment. Scale is scored on Ecosystem Alignment. The criteria and weights are on the Build page.

Genesis is judged as Idea → MVP. Scale is judged as Prototype → Product.
