Roster check (prizes): World $15k · ENS $10k · Uniswap Foundation $10k · 1inch $5k · Sui $5k (= $45k published; prize briefs still “coming soon”). 1inch is new vs the 2026-07-14 four-pack.

  1. NEW prize track: 1inch ($5k) — Portal-first: 17 APIs, Swap/Pathfinder routing, Fusion + Fusion+ (intent / gasless / cross-chain, MEV protection); no judged criteria yet → early edge is shipping a real Fusion+ or Swap-API integration, not a deck.

  2. Sui wedge still live: Hashi (native BTC collateral) on testnet — Official stack page + testnet.hashi.sui.io; community pushing deposit/withdraw flows in-window (Xverse + Sui wallet, Signet faucet). Pain = wrapped-BTC trust + custody; build = UX that makes #BTC → stablecoin borrow feel like one mobile session.

  3. 1inch builder narrative (quiet official, clear product surface) — Community recap of what ships day-to-day: multi-chain best-route swaps, gasless Fusion resolvers, Fusion+ bridges, Developer Portal APIs — aligns with your trading-agent lane if the agent routes via 1inch instead of hand-rolled DEX hops.

  4. Agent payments still the active dev narrative (x402) — In-window: agents paying USDC over x402 on Base (e.g. thesis-audit MCP with on-chain receipt); zerohash’s Agentic Finance Suite (KYA + x402, joined x402 Foundation) still circulating as the “compliance rail” talk. Maps hard to exchange agents + stablecoin rails.

  5. Security incident worth knowing as a wallet/AA builder: Coldcard seed-gen flaw — Weak RNG / seed generation → mass single-sig sweeps (~$38M+ core Chainalysis figure; higher estimates elsewhere); hotfix ≠ safe for seeds born on bad firmware. Reinforce “session keys / social recovery / never re-use weak entropy paths” in any embedded-wallet UX you demo.

  6. Sponsor X silence (ENS / UniswapFND / World / official Sui) — No material SDK, bounty, or Tokyo-specific push from those handles in the 8h window; don’t chase ghost tracks until prize pages fill in.

Build seeds

  1. 7702 + embedded wallet “agent trader” that only ever routes via 1inch Fusion/Fusion+ (intent = gasless, MEV-aware; one-tap limit/DCA from a session key) — double-dips Uniswap narrative only if you add a v4 hook later; primary score on 1inch.
  2. Human-gated x402 paywall for agent APIs using World ID proof before an agent can spend USDC (stops bot spam; delight = “prove human once, agent pays forever under cap”).
  3. Hashi “BTC → borrow stable → spend” flow with adult UX (clear LTV, guardian-layer status, one recovery path) — Sui prize + your CCTP/stablecoin muscle if you bridge spend to Ethereum rails.

Window note: thin on net-new sponsor ship announcements; signal is roster delta (1inch) + Sui Hashi build surface + agent-payment rails + wallet-security reminder — not a flood of Tokyo bounties.
