Roster (web)

  1. NEW prize track: 1inch ($5,000) — not in the 2026-07-14 partner set (ENS / Uniswap FND / World / Sui); now live on the Tokyo prizes page with Pathfinder Swap API, Fusion/Fusion+ intents, 17-API Developer Portal as the build surface (prize details still “coming soon”). Worth a swap/intent UX lane if you already ship trading agents.

  2. Published Tokyo prizes now: World $15k · ENS $10k · Uniswap Foundation $10k · 1inch $5k ($40k) — Sui is not on the current prizes list (was in the Jul-14 confirmed set); World is the largest bag; all four still “prize details coming soon.” Re-check before locking a Sui-first Tokyo plan.

Sponsors on X (last 8h)

  1. Sui devrel is scoring DeFi & Payments builders — @suidevelopers closed the Overflow DeFi/Payments track with merchant rails, gasless dollar accounts, QR pay, micropayments, payroll streams (e.g. NodeRails, Talise, quay); Special/Walrus track next. Payments + embedded-wallet UX is the wedge they’re amplifying, not pure Move demos.
    x.com/suidevelopers/status/2082587040043130908

  2. Sui institutional privacy push — official post on confidential transfers (balances/amounts private; issuers keep view keys; compliance selective disclosure) via Merkle Science Q&A — maps to stablecoin/treasury apps that can’t ship on full public ledgers.
    x.com/SuiNetwork/status/2082542199586292002 · sui.io/blog/rethinking-privacy-for-institutional-finance

  3. Uniswap / ENS / World / 1inch official X: quiet for builders this window — no new SDK/testnet/bounty posts from @UniswapFND, @ensdomains, @worldcoin, or 1inch in-window; World still top Tokyo prize by $ but no Tokyo-specific prize rules dropped. Don’t invent sponsor heat that isn’t there.

Broader crypto-dev (Tokyo leverage)

  1. x402 hits real merchant surface area — CDP Payment Acceptance now supports agentic x402; Coinbase Business merchants auto-enabled, first txs reported same day (stablecoin settlement). Direct fit for your AA + payment-rails stack; merchant acceptance is no longer a demo-only problem.
    x.com/kleffew94/status/2082533311457697978

  2. x402 security layer is the open product gap — Chance ships a pre-sign verifier (token realness, quote/terms match, payee reputation) on Coinbase CDP facilitator + Base after recent x402 exploit disclosures — “agents can pay” is solved faster than “agents pay safely.”

  3. Paid DEV bounty still open (tight deadline) — Hedera x402 bounty: agent payments in HBAR or USDC, five $1k prizes, submit by Jul 31. Useful dry-run before Tokyo even if Hedera isn’t a Tokyo sponsor.

Build seeds

  1. World $15k × x402 safety — Human-gated agent spend: World ID proves a human owner; scoped 7702 session keys + pre-sign payment verifier so agents only pay allowlisted merchants / matched quotes (pain: agent overpay/spoof; delight: one “approve agent budget” UX).
  2. 1inch $5k × trading agents — Intent trading agent that routes via Fusion+/Swap API with human-in-loop policy (max slippage, venue reputation) for Coinbase-Business-class counterparties — not another bare aggregator UI.
  3. Uniswap FND $10k × AA payments — v4 hook that settles agent or payroll micropayments into LP/treasury with gas-abstracted embedded wallets + ENS as the pay-to name (pain: agents/users can’t hold gas or 0x addresses; differentiation: name → intent → settle without wallet chrome).
