Sponsor roster (web)

Published prizes now: World $15k · 1inch $5k · ENS $10k · Uniswap Foundation $10k ($40k total; prize criteria still “coming soon”).
New vs 2026-07-14 roster: 1inch (new track). Sui is not on the published prizes page (was listed Jul-14). World X handle on page: @worldnetwork.

  1. NEW prize track: 1inch ($5k) — Tokyo stack to learn now: Developer Portal (17 APIs), Pathfinder Swap API, Fusion / Fusion+ (intent + cross-chain, MEV protection, gasless).
    takeaway — Your exchange-agent / payment-rail lane maps cleanly onto Swap + Fusion+; prize details TBD so ship a real aggregator/intent demo early.

  2. Uniswap official: “A billion reasons to build on Uniswap” (congrats to @ponsdotfamily on $1B mark).
    takeaway — UF is amplifying consumer/launch volume on Uniswap rails — for Tokyo, bias v4 hooks / Unichain UX that makes non-pro flows feel one-tap, not another DEX UI.

  3. Sui Hashi (BTCFi) still hot on X + product page (testnet community traffic today; product: native BTC collateral on Sui → hBTC / programmable LTV). Note: Sui not on current Tokyo prizes page — treat as watchlist, not confirmed track.
    takeaway — If Sui reappears as a sponsor, BTC-collateral UX + CCTP/stable borrow is an obvious wedge; if not, ignore for prize targeting.

  4. ENS / World — quiet window (no material SDK/prize/devrel push from @ensdomains, @UniswapFND, @worldnetwork / World in this 8h).
    takeaway — Roster is real ($10k ENS / $15k World) but no new builder signal today; default to known ENS naming + World ID / Mini App patterns until prize briefs drop.

  5. Agent-payments narrative: settlement ≠ safety — X discourse: x402 moves money; missing pieces called out as identity (ERC-8004), escrow (ERC-8183), human mandate (x401), adjudication gaps.
    takeaway — Perfect overlap with your AA + stablecoin + agent work: Tokyo demos that compose pay + identity + limits/escrow beat bare x402 “4 lines of middleware.”

  6. Builder security lesson (recent cluster, still circulating): AFX Trade ~$24.15M USDC — protocol bridge validator keys compromised (Arbitrum chain/native bridge OK); Lien Finance ~$542k — bond/OTC input-validation / pricing logic.
    takeaway — For any Tokyo swap/agent/bridge surface: no hot-key quorum, whitelist call targets/selectors, treat permissionless “register asset” paths as exploit surface.

Build seeds (≤3)

  1. 1inch Fusion+ trading agent — EIP-7702 session wallet that only signs Fusion+/Pathfinder intents (spend caps, MEV-safe, gasless UX) for non-custodial “agent that trades for me.”
  2. World-gated agent merchant — World ID proof before an x402/USDC pay endpoint unlocks; human mandate + refund path for AI agents (payment rails × World track).
  3. ENS-resolved payment identity — pay.alice.eth resolves to embedded-wallet + CCTP receive address with 1inch best-route “send any token, land USDC” delight for remittance/merchant demos.
