Roster (live prizes page): World $15k · ENS $10k · Uniswap Foundation $10k · 1inch $5k (NEW vs 2026-07-14 roster) · Sui not listed. Prize details still “coming soon.” Total published: $40k. ethglobal.com/events/tokyo2026/prizes
New Tokyo prize track: 1inch ($5k) — First new sponsor since your Jul-14 list; prize criteria empty, so early Differentiation = ship on their stated stack (Swap API / Pathfinder, Fusion+ intents, Developer Portal APIs) before the rubric freezes. ethglobal.com/events/tokyo2026/prizes/1inch
1inch is pushing intent + MEV-safe routing, not raw AMM UI — Portal copy for Tokyo builders: 17 APIs, Pathfinder routing, Fusion/Fusion+ for intent + cross-chain swaps with MEV protection and gasless UX as defaults. Aligns with your exchange-agent / payment-rails lane. ethglobal.com/events/tokyo2026/prizes/1inch
Uniswap: Robinhood-era Instant Launch surface is the live build surface — On-chain sleuthing ties TOYODA to Uniswap SDK main-branch
INSTANT_LAUNCH_STRATEGY_FEES_ON_ROBINHOOD; Uniswap also shipped a Launches entry on-site. Tokyo UniswapFND track will reward v4/hooks/launch UX more than vanilla swaps. x.com/Bullieonchain/status/2083046119609651316 · x.com/Uniswap/status/2082949944105730392Uniswap pain → wedge: public mempool = free front-run — GhostSwap (WTF hackathon) encrypts swap intent, private-matches, settles last on real DEX; Sepolia verified, Nox matching still simulated. 1inch Fusion’s MEV-protect story is the production-shaped answer to the same pain. x.com/thenicovale_/status/2082976527990378766
Sui ecosystem pain (Hashi BTC testnet): deposits OK, exits broken — Testers report multi-day pending withdrawals and min withdraw hiked to 10 hBTC while Signet faucet is scarce; asks for proper Discord/X feedback loop. If Sui reappears on Tokyo prizes, BTC-collateral UX is an open wedge. x.com/sarbadeen/status/2082994080053678127
x402 is past demos: agents pay $0.42 USDC to deploy onchain assets — B20 launchpad on Base: hold token → x402 call → gasless-sig deploy via cc0company SDK (browser/injected wallets only in beta). Your agent-payments track has a concrete pattern to clone onto stablecoin rails + sponsor swap APIs. x.com/Theunsecretman/status/2082950427587338525
Narrative shift: payments solved, agent disputes are not — Devs shipping x402+A2A stacks report both agents “succeed,” money moved, no native endpoint for “what delivered meant.” Court/settlement layer is the missing delight for Tokyo multi-sponsor (World human-check + 1inch settle + ENS identity). x.com/Navtq0808/status/2083091037174816845
AA/passkey agent wallets hitting real user friction — MoonPay PayBox loop (passkey wallet + Claude/ChatGPT agent spend) is viral, but users stuck on “Preparing… / Add passkey” and claim flows—same UX class as EIP-7702 + embedded wallets you already ship. x.com/pokkiri_kk/status/2083056878482084168 · x.com/TeeJhay50b/status/2082968559907451151
Quiet this window: World ID / @worldnetwork SDK or Tokyo bounty signal; official @ensdomains product push (Lisbon prize recap was earlier, outside 8h); new audit contests / grants paying real DEV work; net-new security incidents (Ostium postmortems are older recirculation).
Build seeds
- Passkey agent swap desk — embedded 7702 wallet + policy-bounded agent routes via 1inch Fusion+ (MEV-safe, gasless) with human-in-loop approve; World ID gate optional for “real human” spend caps.
- Private intent → public settle — GhostSwap-class encrypted intent that settles through 1inch/Uniswap paths, not a new AMM; demo big-trade no-sandwich UX for UniswapFND + 1inch dual.
- x402 “receipt + dispute” mini-protocol — after agent payment, both parties pin ENS-named delivery claim; timeout + optional World human-attest resolves “both logs green, user angry.”
