🧠 Challenge: Build the Onchain Coworking Stack

by ETHWarsaw & Kolektyw3

Kolektyw3 is a coworking and community hub in Warsaw, built for people working in blockchain, AI, and decentralized tech. It’s an ecosystem where founders, hackers, and creatives collaborate, share knowledge, and build together.

We’re designing a new kind of space. One that is programmable, community-owned, and natively onchain.

Your challenge is to build tools that make spaces like Kolektyw3 run better.

🎯 What we’re looking for

Build a product that is actually useful for a real-world coworking + community hub, and meaningfully uses blockchain.

This is not about forcing blockchain into things.

It’s about using crypto where it makes sense.

⚙️ Example problem spaces

You don’t have to stick to these, but they’re a good starting point:

🏢 Space & Resource Management

• Booking system for meeting rooms or desks
• Onchain payments for usage (hourly, subscriptions, deposits)
• Dynamic pricing based on demand or membership tier
