Second International Eclipse Tractus-X Hackathon — 06 Nov 2026, Stuttgart, Germany

Hi Everyone 👋,

After the great energy of our first international Open Source Hackathon in Bilbao this February, it is time for round two: we are happy to invite you to the Second International Eclipse Tractus-X Hackathon, taking place on November 6, 2026 at ARENA2036 e.V. (Pfaffenwaldring 19, 70569 Stuttgart, Germany)! 🚀

This time we have one big mission: re-architecting the Eclipse Tractus-X Portal — and we want to do it together with you, in a design thinking and programming hackathon. On-site in Stuttgart, or optionally online.

Event Details​

  • 💸 Cost: FREE 🆓
  • 📅 Date: 6th of November 2026
  • 📍 Location: ARENA2036 e.V., Pfaffenwaldring 19, 70569 Stuttgart, Germany ARENA2036 on Google Maps
  • ⏰ Duration: Full Day Event
  • 🧠 Format: Design thinking and programming — we shape the target architecture together and start building it on the same day
  • 💻 Participation: On-site at ARENA2036 — joining online is optionally possible, just mention it in your email

✉️ Interested? Let Us Know​

There is no registration form this time — if you are interested in joining, simply send an email to mathias.moser@catena-x.net with your name, your organization, and a short note on what you would like to work on. We will get back to you with all further details. 📬

Please reserve the date!

Places are limited and the hackathon is a hands-on developer event — so if you are planning to come, let us know as early as possible so we can plan the challenges and the room accordingly.

‼️ IMPORTANT​

  • Please reserve this date if you're willing to come! 🗓️
  • This is a "WORKING/DEVELOPING" hands-on event — send this to your developers!
  • It is meant to be technical and we will be solving challenges together
  • This is NOT a "business oriented" event
  • SO BRING YOUR LAPTOPS! 💻 And lots of motivation to code and learn! You can use your favorite IDE (we recommend visual studio code!)

🎯 The Mission: Re-architecting the Eclipse Tractus-X Portal​

The main reason for this hackathon is the re-architecture of the Eclipse Tractus-X Portal. The Portal is the front door of every data space built on Tractus-X technology — it is where companies get onboarded, register, and start participating. We want to make it:

  • ✨ Simpler — a leaner architecture with fewer moving parts
  • 🔧 Easier to maintain — so the community can keep it evolving without a steep learning curve
  • ⚡ More performant — fast where it matters, from the first login to the last onboarding step
  • 🚀 Easier to use for data space onboardings — so onboarding into a data space with Tractus-X tech becomes straightforward, for operators and participants alike

🧠 Design Thinking + 💻 Programming​

This is not a "code first, think later" hackathon. We will start with design thinking: together we look at how onboardings work today, where the friction is, and what a simpler Portal architecture should look like. Then we switch into programming mode and start building the first pieces of that architecture — hands-on, in the open, in the Tractus-X repositories.

Whether you are an architect, a developer, a product person, or someone who has onboarded companies into a data space and knows the pain points first-hand — your perspective is needed at the table.

The detailed agenda and the concrete working tracks will be announced closer to the event. Do you have ideas, requirements, or war stories about the Portal and onboarding? Tell us in your email!

📢 Official Communications​

The official agenda, the challenges, and all further updates will be shared via:

Keep tuned for the latest updates!

🔙 Looking Back — Hackathon I in Bilbao​

In February 2026, the Eclipse Tractus-X community met for its first international hackathon in Bilbao, Spain — a full day of coding on the Tractus-X Identity Hub Wallet and the Industry Core Hub, hosted by our Project Lead Mikel Garcia and LKS Next. It showed what a room full of motivated developers can achieve in a single day, and it is exactly that spirit we want to bring to ARENA2036 in November.

📍 One Month Before the Community Days​

The hackathon takes place just a few weeks before the Seventh Eclipse Tractus-X Community Days (December 3–4, 2026), also at ARENA2036. What we build together in November is a perfect warm-up — and a great story to share with the whole community in December.

Let's build dataspaces! 🚀
