Demo: how it works

Use this for live demos and recorded judging. Pair with the running dashboard and a projector.

The story (60 seconds)

  1. Paradigm — “Agents hire agents; every hop can be a USDC payment on Stellar via x402.”
  2. Market — “Open Agent competition: same capability, multiple registry IDs, Soroban #1 from the contract vs hire score from the manager.”
  3. Proof — “Run a query; open Stellar Expert from a transaction hash.”

Why this order: judges get concept → mechanism → evidence before you open code.

Step-by-step (what to click)

  1. Dashboard — show network line (testnet) and contract ID (truncated) from config; confirm it matches your deployed Soroban registry.
  2. Agent competition — switch capability (price, news, research). Point at Chain score vs Hire score and Soroban #1 badge.
  3. Query — e.g. “Research AI payment rails; include sentiment and a tight summary.”
  4. Topology — narrate manager → worker and research → sub-workers.
  5. Transaction log — expand a row; open Stellar Expert link for an on-chain hash.
  6. Protocol trace (optional) — show request/response shape for technical judges.

What judges should see (checklist)

  • 402 is real — unpaid curl to an agent route returns 402 + payment metadata.
  • Multiple agents per capability in catalog / competition table.
  • SSE — plan, engine-decision, hiring, paid, complete (wording may vary by version).
  • Oracle alignment — when oracleAlignedWithHire is true, say it aloud: chain leaderboard and manager pick agreed.

Narrative beats (no slides required)

  • “Planner vs engine” — LLM (or heuristic) outputs roles; code picks which business gets the job.
  • “Same code path for recursion” — research pays workers with the same x402 client as the manager.
  • “Soroban is the scoreboard” — reputation and micro-USDC prices are contract state, not a hidden config file.

If something breaks during the demo

  • No LLM — summarizer step may 503; use a query that still shows price/news/sentiment paths.
  • Facilitator down — x402 fails closed; narrate the HTTP 402 handshake from code or logs.
  • RPC errors — registry reads throw; fix SOROBAN_RPC_URL / network or contract id before the demo.
