Compose the Future on Stellar

The best smart contract platforms aren't just built—they're built together. Composability is key to a thriving ecosystem, and that starts with you. Instead of building from scratch, join us for the final hackathon in our mini-hackathon series where we spotlight and build directly on top of real, live projects on Stellar.

This month we’re featuring 2 projects: KALE and Reflector.

KALE is a proof-of-teamwork meme token where participants stake, complete work and harvest their rewards. This is not a winner takes all farming contract. Rewards are distributed to all working farmers based on their contributions. The community has open sourced different miners, from web-based to GPU-enabled, so that anyone can participate, even from your phone!

Reflector is a push based Stellar native oracle that features price feeds for classic assets, fx rates and Cexs/Dexs. Reflector operates as a DAO with decisions being governed by its token and node operators. Due to how the smart contract side operates, oracles like Reflector are required on Stellar to integrate classic asset pricing.

The Challenge: Build on KALE and/or Reflector

This isn't about broad concepts; it's about targeted innovation. Your mission is to build a new tool, feature, or integration that directly leverages or enhances KALE or Reflector. We want to see how you can use them as a foundational layer to create new user experiences and financial solutions. While both of these projects are vastly different, we hope that together their open nature will foster fun new experiences on Stellar. To help you get started both projects have provided a workshop video to get you quickly up to speed on the project and structure of their code.
