Roster check (web, live prizes page): New sponsor 1inch ($5k). Published tracks now: World $15k · ENS $10k · Uniswap Foundation $10k · 1inch $5k (= $40k published; prize details TBA). Sui is not on the published prize list (was in your 2026-07-14 set). Official sponsor handles: quiet on X this window.

  1. NEW prize track — 1inch ($5k) — Re-target trading-agent / swap UX work at intent + aggregation, not just Uniswap; new track = new scoring surface.

  2. 1inch stack they are advertising for builders — Developer Portal (17 APIs), Pathfinder Swap API, Fusion / Fusion+ (intent-based + cross-chain, MEV protection, gasless) = natural fit for your exchange-agent + payment-rails lane.

  3. Sui dropped from published Tokyo prizes — Do not plan a Sui-primary submission until they reappear; keep Sui as optional multi-track only.

  4. Standing tracks (amounts locked, criteria still “coming soon”) — World $15k (human vs AI / inclusive finance), ENS $10k (names as universal pointers), Uniswap Foundation $10k (v4 / Unichain / grantee-style DeFi innovation).

  5. x402 is the agent-payments primitive devs are wiring today — AWS documents MCP + A2A + AG-UI + x402 (HTTP 402 micropayments, spend limits, retry) as the open agent stack; maps cleanly onto Tokyo + your agent-payments history.

  6. Live paid practice: Arc Programmable Money Hackathon — Circle’s stablecoin-native L1 hackathon runs ~Jul 13–Aug 22/23; USDC-as-gas, agent payments, commerce stack — free reps before Sep Tokyo.

  7. Builder security: WEMIX$ contract breach ~$724k USDC.e — Bridges/LPs suspended after stablecoin-adjacent contract compromise; treat bridge/stablecoin mint paths as high-scrutiny in any Tokyo payment rail.

Build seeds

  1. 7702 embedded wallet → 1inch Fusion+ intent swap agent with session spend caps and gasless UX (1inch track × your AA/trading agents).
  2. World-gated agent spender: humanId step-up only when agent exceeds policy; otherwise silent USDC micropays via x402 (World × agent payments).
  3. ENS-named trading desk: desk.eth text records hold policy + resolver → Uniswap v4 hook for settlement receipts (ENS × Uniswap).
