Sponsor roster (web)

  1. NEW prize partner: 1inch ($5k) — live Tokyo prizes page now lists World $15k · 1inch $5k · ENS $10k · Uniswap Foundation $10k ($40k published); Sui is not on the roster (was in the Jul-14 / Coinsaga $55k set). Prize details still “coming soon.” New track = new build surface.

Sponsor drill-down (X · last 8h)

  1. 1inch is teeing “underutilized liquidity” (Aqua/SwapVM lane) — official post in-window: “Underutilized liquidity will soon be utilized.” Read with their Lisbon builder ask (Aqua apps + SwapVM opcode mods, $5k split) as the nearest template for what a Tokyo 1inch track will reward: capital-efficiency apps, not another thin aggregator wrapper.

    github.com/1inch/swap-vm

  2. ENS / Uniswap FND / World / Sui — quiet in-window — no official SDK/bounty/devrel posts from those handles in the 8h window worth a wedge. (Recent but outside window: ENS Reverse Record #7 + Universal Resolver narrative; Sui gas-free stables / confidential transfers / Basecamp Oct; UF/Hayden on Robinhood-chain RWA pool volume + fee→UNI burn votes.)

Broader crypto-dev (build leverage)

  1. Circle Arc “Programmable Money” hackathon is live through ~Aug 22 — judges want a working Arc prototype + real use of Circle tools (Wallets, Contracts, CCTP, Gateway, Paymaster, Nanopayments); quality > complexity. Direct practice for your AA/CCTP/rails stack before Tokyo.

  2. Japan institutional yen rails: SBI JPYSC on Ethereum (Startale infra) — circulating hard today: Japan’s first trust-based yen stablecoin from SBI, production issuance on Ethereum (community claims ~$70M day-one). Local Tokyo narrative = JPY stable settlement, not more USD-only demos.

  3. Bridge/security lesson: Across Solana hit (Jul 17) — relayer capital, not user deposits — first disclosed Across incident after large lifetime volume; loss on Risk Labs relayer ops, in-flight user transfers completed, Solana deposits re-enabled ~Jul 18; full post-mortem still pending. Builder takeaway: intent bridges + operator isolation vs shared pools.

Build seeds

  1. 1inch + AA: embedded-wallet “one-tap rebalance” that routes idle ERC-20 balances into an Aqua/SwapVM strategy with Fusion+ MEV-safe exit — demo capital efficiency, not a new DEX UI.
  2. World + payments: human-gated agent pay agent (World ID / AgentKit) that only unlocks CCTP/USDC micropayments after proof-of-human — kills bot drain of free faucets/paymasters.
  3. Uniswap + Tokyo rails: JPYSC (or USDC) ↔ tokenized equity/RWA hop on Uniswap v4 with a Japan-facing checkout (ENS name as payee) — institutional-yen narrative × UF prize lane.
