Sponsor roster (web)

NEW prize track: 1inch ($5k); Sui gone from published Tokyo prizes; live roster = World $15k · ENS $10k · Uniswap Foundation $10k · 1inch $5k ($40k total; prize details still “coming soon”).
ethglobal.com/events/tokyo2026/prizes

  1. 1inch is a Tokyo prize partner — new $5k track; portal pitch is Pathfinder Swap API + Fusion/Fusion+ (intent/cross-chain, MEV protection) across 12+ chains — map any payment/AA/trading agent demo to their APIs.

  2. Sui not on current Tokyo prizes page (was in the 2026-07-14 set) — drop Sui-primary Tokyo scoping until they reappear; their own push this window is still Hashi = native BTC collateral on Sui Devnet.

  3. @SuiNetwork → builders: “what would you build first for $BTC with Hashi?” — BTC stays on Bitcoin; Sui contracts orchestrate collateral (MPC + guardian). Wedge if they re-sponsor: BTC-backed stable borrow / payment rails in Move.

  4. 1inch product surface (same-day web/X): syrupUSDC / syrupUSDT (Maple) live on Swap + API (ETH/Arb/Base / ETH+BNB) — tokenized institutional credit routed as normal DeFi liquidity; good Fusion+ demo fuel for the new track.

  5. Uniswap v4 hooks are where builders are shipping (bonding curves, tax→PSM, Stable Hooks narrative) — UF Tokyo $10k will likely reward real hook utility, not generic AMM UI.

  6. x402 agent micropayments still live-build — Hilt shipped TS/Python SDK 1.2.0 (x402 V2 helpers, atomic entitlements); independent builder reports autonomous agent as repeat USDC API customer on Base. Aligns with your agent-payments + AA lane; pair with World human-check if you need anti-bot.

  7. Bridge exploit lesson (Wanchain Cardano↔BNB, ~515M $NIGHT / ~$9–13M) — message/signature-reuse class bug; core L1s fine, bridge wrong. For Tokyo: treat cross-chain messaging + wrapped assets as first-class threat models (esp. CCTP/payment rails).

  8. Cosmos Labs trialing bug bounty move to Immunefi (from HackerOne, from Mon 27 Jul, 90 days) — security tooling / hunter UX remains fundable DEV work if you want a side bounty lane.

World (@worldnetwork on prize page): no material SDK/devrel signal in-window; $15k largest single pot, criteria still TBD.

ENS: no in-window official release; track still $10k.

Build seeds

  1. 1inch track: 7702/embedded-wallet agent that pays APIs (x402) then exits/enter yield stables via Fusion+ + syrupUSDC with one intent — human never sees routes.
  2. Uniswap Foundation track: v4 hook that turns stablecoin payment settlement into concentrated LP + auto fee-to-gas sponsor (delight = “send USDC, gas/fees disappear”).
  3. World + ENS: World ID–gated named pay link (you.eth → merchant) that only real humans can open, with AA session keys for agent refill under spend limits.
