Sponsor roster (web)

  1. NEW prize track: 1inch ($5k) — not on the 2026-07-14 partner list; prizes page now lists 1inch + World ($15k) + ENS ($10k) + Uniswap Foundation ($10k) = $40k published (prize details still “coming soon”). Sui is absent from the current prizes page (was on the Jul-14 confirmed set with $55k published). ethglobal.com/events/tokyo2026/prizes · ethglobal.com/events/tokyo2026/prizes/1inch
    takeaway — Re-target builds: open a 1inch Pathfinder / Fusion+ intent lane; treat Sui as optional ecosystem leverage until it reappears on prizes.

  2. 1inch wants builders on the Developer Portal stack (17 APIs, Swap API + Pathfinder, Fusion / Fusion+ intent + cross-chain swaps, MEV protection, gasless UX) — prize copy is the clearest Tokyo product brief for this new track. ethglobal.com/events/tokyo2026/prizes/1inch
    takeaway — Best Tokyo angle is an agent or AA wallet that settles best-route/intents via 1inch APIs, not another bare swap UI.

  3. World is the largest published purse ($15k); about-copy = human-vs-AI, inclusive finance, real-human connection; details TBA; X handle on page is @worldnetwork. ethglobal.com/events/tokyo2026/prizes/world
    takeaway — Wire World ID / human-gated controls into any agent-payment or high-value flow (stops bot drain of sponsorship/gas).

Sponsor ecosystem (X + product)

  1. Sui Hashi (BTCfi): native BTC as programmable collateral on Sui — official push: BTC stays on Bitcoin; DeFi on Sui; “testnet coming soon”; product site says now on Sui Devnet, docs + GitHub live. x.com/SuiNetwork/status/2079324500043427920 · sui.io/hashi · devnet.hashi.sui.io/ · mystenlabs.github.io/hashi/design/index.html
    takeaway — Even if Sui is off the prizes list today, Hashi is the live wedge (custody/bridge pain → code-enforced BTC collateral); only worth deep-build if Sui re-sponsors.

  2. ENS (just outside strict 8h, still the only ENS signal): Security Council activation passed — 5-of-8 cancel authority on timelocked malicious proposals (Beanstalk / BonkDAO / Tornado-style governance attacks cited); term → Jul 2028. x.com/ensdomains/status/2079265430687154211 · ens.domains/blog/post/introducing-the-newest-ens-security-co
    takeaway — Weak for a flashy dApp; strong for security-tooling / name+governance safety demos under the ENS $10k track.

Broader crypto-dev (build leverage)

  1. WalletLock ships open-source revoke for allowances, Permit2, and EIP-7702 delegations — direct hit on 7702 attack surface. x.com/ChinesePowered/status/2079383173469982981 · walletlock.chinesepowered.com/ · github.com/sexychinese/walletlock
    takeaway — Security tooling wedge for Tokyo: 7702 delegation hygiene next to your AA/embedded-wallet stack.

  2. x402 agent payments maturing as infra, not demos — Naven Payment Intents live (B2B accept x402 without running your own facilitator); Fidio live on OKX agent marketplace as pay-per-call x402 brand kit. x.com/NavenNetwork/status/2079463076454351012 · x.com/FidioHQ/status/2079466794000019543
    takeaway — Agent-payment rails are productized; combine x402 + stablecoin settlement + human gate (World) for a multi-track story.

  3. Base Cobalt (Sep 2026) → native AA via EIP-8130 (gas sponsorship, batching, session keys; claimed large gas/size wins vs ERC-4337); WalletConnect + Optimism path to portable AA across EVM. Timing overlaps Tokyo Sep 25–27. x.com/Niloy2133936650/status/2079438068432719898 · kucoin.com/news/flash/base-to-implement-native-account-abstr · eips.ethereum.org/EIPS/eip-8130 · eip8130.io/
    takeaway — Your 7702 + embedded-wallet muscle maps cleanly onto post-Cobalt native AA UX; prototype against 8130/7702 dual-path before Tokyo.

Build seeds

  1. Intent pay-desk (1inch + x402 + AA): agent or user requests a spend; 1inch Fusion+/Pathfinder finds route; x402 settles the API/agent fee; EIP-7702 session key bounds the spend — human-gate optional via World ID.
  2. 7702 safety co-pilot (ENS + security tooling): WalletLock-style scan/revoke of 7702 delegations + ENS reverse-resolve of operators, with a “safe name for this dapp” check before approve.
  3. Cobalt-ready gasless checkout (Uniswap/1inch rails): embedded wallet that uses sponsored/batched AA for stablecoin payments and best-route swap-on-demand, designed so EIP-8130 is a drop-in upgrade in September.
