We're building Sehat for the @QVAC hackathon 🩺 β€” a family health assistant that runs 100% on one home PC. No cloud, no accounts, your records never leave the house. Ask "how has Dad's blood sugar changed?" β†’ it reads your real lab reports and answers with citations, by text or voice, in any language. Why on-device? Health data is the most private data you own. It shouldn't need a server. #teamSehat

Meet Sehat 🏠🩺 β€” a family health assistant that runs 100% on ONE home PC, built for the @QVAC Hackathon. No cloud. No accounts. No subscriptions. Your family's lab results, prescriptions and notes are read, understood, and answered entirely on-device β€” they never leave the house. Why? Health data is the most sensitive data a family owns. With QVAC's local-first SDK, privacy isn't a setting β€” it's the architecture. Open source, Apache-2.0. Follow along πŸ‘‡ #teamSehat

Tiny win tiny bug from shipping the 1Shot mainnet relay: βœ… send7710Transaction β†’ returns a TaskId, relay accepted, gas in USDC. πŸ› relayer_getStatus throws "undefined is not an object (hex2.startsWith)" server-side β€” so you read the tx off-chain instead. Loved the relayer otherwise β€” no signup, just JSON-RPC. @MetaMaskDev

Spent the last stretch giving Sebutkan a cozy, anime study-room feel (art generated with @Venice_AI's image endpoint) an interactive guided tour that points at every feature. A serious on-chain agent doesn't have to look like a terminal. πŸͺ΄ @MetaMaskDev

Cited an author who hasn't joined yet? Their share is recorded on-chain and waits in escrow. They prove their ORCID (OAuth), bind a wallet with one signature, and withdraw β€” plus a 12% citation-loyalty yield. Zero gas for them. @MetaMaskDev

One click: attestAndSplit records the citation AND pays each author in a single on-chain tx β€” no relayer fee, the contract blocks double-pay. Proof: basescan.org/tx/0x6f4c8d53…8480c (EIP-7702, βœ“ Success). It's all real. @MetaMaskDev
18
Authors get paid gasless on Base mainnet via the 1Shot permissionless relayer β€” a real ERC-7710 redeem with an EIP-7702 account upgrade, gas paid in USDC. Live relayer call the on-chain tx, in the demo πŸ‘‡ @MetaMaskDev

Under that one permission, the agents reason with @Venice_AI β€” private & uncensored β€” across 5 endpoints in the main flow: chat, web-search, embeddings, image, and TTS. The embeddings don't just dedup β€” they weight who gets paid. @MetaMaskDev #AIagents
20
Sebutkan isn't one agent β€” it's a mesh. The Researcher redelegates strictly narrower budgets (ERC-7710) to a Planner β†’ parallel Readers β†’ a Fact-checker β†’ a Summarizer. Authority only ever shrinks, and the Fact-checker can reject a weak answer & force a revision. @MetaMaskDev
14
The whole product hinges on @MetaMaskDev Advanced Permissions (ERC-7715). You sign once: "up to 10 USDC for this 24-hour grant." A hard cap that auto-expires. No per-action popups, no blanket approval, no custody. The first agent-spending UX I'd actually trust.

AI scrapes humanity's research and pays the authors nothing. So I built Sebutkan πŸͺ™ β€” a research agent that cites AND pays its sources. Sign ONE @MetaMaskDev Advanced Permission. The agent researches with @Venice_AI and splits USDC back to every author it cites β€” on-chain, non-custodial. πŸ”— sebutkan.vercel.app #MetaMask #SmartAccounts

AI reads our research & pays authors nothing. Sebutkan fixes it: sign ONE @MetaMaskDev Advanced Permission β†’ an agent buys papers, reads them with @venice_ai, and pays every cited author in USDC β€” gasless via 1Shot. πŸ”— sebutkan.vercel.app
