Roster delta (web): Prizes page now lists World $15k · ENS $10k · Uniswap Foundation $10k · 1inch $5k — prize details still “coming soon.”1(https://ethglobal.com/events/tokyo2026/prizes)
NEW vs 2026-07-14 list: 1inch is on the roster; Sui is not among the four published prize tracks.1(https://ethglobal.com/events/tokyo2026/prizes)

  1. 1inch is a new Tokyo prize track ($5k) — primary wedge is intent/cross-chain swaps (Swap API + Pathfinder, Fusion/Fusion+, 17-API Developer Portal), not “another DEX UI.” — ethglobal.com/events/tokyo2026/prizes/1inch
    takeaway: Rehearse a shippable 1inch-API integration (Fusion+/MEV-protected path or agent/trading route) so you can claim this track the day prize rubrics drop.

  2. ENS is openly scoring Lisbon winners as Tokyo-relevant patterns — passkey name→wallet (ENSignv2), agent mini-apps under ENS (Atlas), human-only trust graph on ENSv2 subnames (VouchMe); framing: “names as infrastructure.” — x.com/ensdomains/status/2082848180782379064
    takeaway: Your AA/7702 + embedded-wallet stack maps cleanly to the Continuity pattern they just paid for; avoid pure naming demos.

  3. 1inch is devrel-pushing Aqua (shared liquidity) hard today — Lisbon talk clip on what Aqua enables for LPs + step-by-step “first position” guide; co-founder birthday post re-anchors Aqua on Ethereum. — x.com/1inch/status/2082803350769148125 · x.com/1inch/status/2082836625797578924
    takeaway: If you touch Uniswap and 1inch, differentiate on LP/intent UX on Aqua rails, not vanilla swaps.

  4. World ($15k largest published Tokyo prize) — quiet window on X/SDK — page still generic (human vs AI, inclusive finance); no prize rubric or SDK push in-window. — ethglobal.com/events/tokyo2026/prizes/world
    takeaway: Treat World as the open slot for human-gated agent spend / payment rails once details land; don’t block prep on it today.

  5. Uniswap Foundation — quiet on X this window — Tokyo prize still $10k, details TBD; no new v4/Unichain/devrel post in the 8h sample. — ethglobal.com/events/tokyo2026/prizes
    takeaway: No new signal to re-scope; keep a thin Unichain/v4 hook only if it multiplies a 1inch/ENS demo.

  6. x402 agent payments are the live build narrative — Circle Dev: agents discover API → pay USDC per request (x402 + Circle Agent Stack); parallel: agents launching paid launchpads via x402. — x.com/BuildOnCircle/status/2082872673189986690 · x.com/jenilt/status/2082828658591588512
    takeaway: This is the cleanest bridge from your exchange-agent + stablecoin track to World/ENS identity + 1inch execution.

  7. x402 security landmine (wedge, not hype) — claim that all 15 x402 payment facilitators failed a USENIX-linked audit (free API calls / two-phase payment gap); Masumi shipping a fix write-up. — x.com/MasumiNetwork/status/2082873936115544373 · masumi.network/blogs/x402-protocol-security-two-phase-gap
    takeaway: A Tokyo demo that hardens agent micropayments (atomic pay→serve, no free replays) beats another “agent pays API” toy.

  8. Builder security lesson (small $$, clean class) — SlowMist: Index Coop / Set Protocol ExchangeIssuance TOCTOU via malicious Set manager pre-issue hook inflating positionMultiplier (~$9.6k residual drain). — x.com/SlowMist_Team/status/2082767887245410320
    takeaway: If you ship any “issue / route / hook” surface, freeze quoted state before pull — classic helper-contract pitfall.

Sui note: Official reply in-window was conference early-bird logistics (deadline Jul 31), not Tokyo prize/SDK; Sui is absent from current Tokyo prize list — deprioritize unless they reappear. — x.com/SuiNetwork/status/2082873160668680328 · ethglobal.com/events/tokyo2026/prizes

Build seeds

  1. ENSv2 passkey wallet + World human check + 1inch Fusion+ “one-tap spend” — FaceID/passkey mints you.tokyo.eth, World gates agent spend caps, 1inch executes MEV-safe swaps (ENS Continuity × World × 1inch).
  2. Hardened x402 agent terminal for trading/payment APIs — Circle-style pay-per-call, with two-phase commit so facilitators can’t double-serve free; settle via USDC, optional 1inch path for non-USDC inventory.
  3. Agent-named mini-app under ENS that only humans can authorize — Atlas-style ENS app identity + VouchMe-style human graph for spend approvals, 1inch/Uniswap as execution backend (anti-bot delight vs pure agent spam).
