Competition Tracks

Four tracks.
Pick one. Ship something real.

Register Now

Every track is judged on the same principle: does it actually work autonomously? Specific challenges and judging criteria released to registered participants before the event.

🛒
Track 01
Agentic Commerce
Build agents that participate in autonomous commercial transactions — procurement, negotiation, fulfilment, or agent-to-agent commerce. This track is built around the core theme of AIS26.
Agent-to-agent payments Autonomous procurement Commerce workflows Nanopayments
💹
Track 02
Agentic Finance
Autonomous agents operating in financial contexts — trading, DeFi, on-chain operations, or portfolio management. Judges look for genuine autonomy, not just LLM wrappers calling an API.
On-chain agents DeFi automation Risk management Multi-agent coordination
🤖
Track 03
Personal Assistant
Agents that genuinely replace manual work in a user's daily or professional life. High bar: it has to work reliably without human oversight, not just look impressive in a demo.
Autonomous research Workflow automation Calendar & comms Multi-step task execution
⚙️
Track 04
Agent Infrastructure
Build the tools, protocols, or primitives that other agents depend on. Memory systems, identity layers, inter-agent communication, orchestration frameworks, or evaluation tooling.
Agent memory Identity & trust Orchestration ERC-8004

Confirmed Workshops

Learn from the infrastructure teams.

Three hands-on workshops from partners who are building the infrastructure agents run on. Access to their teams throughout the weekend.

Workshop Partner
Circle
Payments infrastructure for the agentic economy. Learn how to integrate programmable money movement into your agent — USDC, cross-border settlements, and autonomous payment flows built for machine-to-machine commerce.
Workshop Partner
Cloudflare
Deploy agents at the edge. Cloudflare's developer platform — Workers, Durable Objects, AI Gateway — gives your agent the infrastructure to run reliably at scale without managing servers.
Workshop Partner
NEAR
On-chain agent identity and autonomous transactions on NEAR. Build agents that can own accounts, sign transactions, and interact with smart contracts without human intervention.
Who Should Participate

You don't need a team
to show up.

Solo participants welcome — we run team formation on Day 1. The only requirement is that you're serious about building something that works.

💻
Developers
Backend, frontend, ML engineers. If you can ship code, you belong here. Agent experience helpful but not required.
🎨
Designers
Product and UX designers who want to work on how humans interact with autonomous systems. Underrepresented and highly valued in hackathon teams.
🧭
Domain Experts
Finance, commerce, legal, healthcare — deep domain knowledge paired with builders is often the difference between a demo and a product.
🚀
Founders
Early-stage founders who want to validate a product idea in a structured environment with feedback from builders and potential investors in the room.

Judging criteria

Every submission is evaluated on the same four dimensions regardless of track:

  • Genuine autonomy — does it act without human prompting?
  • Real-world viability — could this ship as a product?
  • Technical quality — architecture, reliability, efficiency
  • Demo quality — can you explain what it does and why it matters?

19 June starts the clock.

Register on Luma now. After the opening ceremony, you'll move to DoraHacks for submissions.

Solo participants welcome — team formation happens on Day 1.
