Roster check (tokyo2026/prizes): published prize partners are World $15k · 1inch $5k · ENS $10k · Uniswap Foundation $10k (~$40k). 1inch is not in your prior list. Sui is not on the published prizes page right now (your $55k/Sui roster may be stale or pre-publish).
NEW prize track: 1inch ($5k) — third-party Swap/Fusion/Fusion+ + 17-API Developer Portal is now a Tokyo track; intent/cross-chain swaps + Pathfinder are the obvious integration surface (prize criteria still “coming soon”).
ethglobal.com/events/tokyo2026/prizes/1inchENS (@ensdomains) pushing Universal Resolver as the stable integration surface — “one consistent entry point” so apps don’t relearn resolution as ENSv2 evolves; name-as-UX for AA/7702 + embedded wallets.

JCB × Circle MOU (same-day, Japan-local) — Japan’s card network exploring USDC for cross-border treasury + in-store merchant/tourist payments; multi-chain interoperability called out — strongest Tokyo-local payment-rail signal in the window.

Direct map to trading-agent + payment-rail builds.

validateUserOppassed attacker as signer; ECDSA fail → fell through to attackerisValidSignature. Signature-validation discipline for 7702/embedded AA is non-optional.
x.com/GoPlusSecurity/status/2076961718971089380Paid security work — Intuition bug bounty live on Immunefi, up to $100k critical, PoC required, USDC on Ethereum, no KYC (useful if you want contest-mode security practice before Tokyo).

Build seeds
- Tourist USDC checkout (JCB wedge × 1inch × ENS): 7702/embedded wallet → ENS login → 1inch Fusion+ route any chain → USDC pay intent for a JP merchant demo, human-readable receipt name.
- Agent pay desk (x402 × Uniswap FND × 1inch): exchange agent that quotes, swaps via 1inch/v4 hooks, settles API/agent calls over x402+USDC with hard spend caps.
- AA sig-guard kit (security tooling × World/ENS): static + runtime checker for 4337/7702
