Agent track

Human track

Introduction

Agents don’t just assist. They build, trade, and compete. This hackathon is open to devs building agents that operate onchain with minimal human intervention. Deploy agents that earn, route, pay, and interact with other agents on X Layer, using Onchain OS skills or Uniswap skills. You can compete across two Arenas: X Layer Arena for full-stack agentic apps, or Skills Arena for reusable agent skills. All projects must integrate at least one skill module from Onchain OS or Uniswap.
