Uniswap v4 brought programmable hooks to DEX liquidity. We’re bringing programmable policy to AI agent payments. Q402 Hooks adds compliance checks, spending rules, reputation gates, oracle conditions, and multi-payee splits before settlement. Payments shouldn’t just move. They should understand the rules. Available in Claude, Codex, and other MCP clients this Thursday. Install: npx -y @quackai/q402-mcp Quack AI ships 24/7. Apparently, sleep isn’t in the roadmap.

AI agents shouldn’t pay every wallet they’re told to. Introducing Q402 Reputation Gate. Before settlement, Q402 verifies the recipient’s ERC-8004 agent identity and checks whether it meets your reputation threshold. No match. No trust. No payment. Programmable trust for agent payments. Live through Q402 Hooks in Claude, Codex, and MCP clients.

An AI agent can decide what to pay. Q402 decides what it's allowed to. Q402 Hooks 1.0 - Live on @BNBCHAIN. Set spend caps, recipient allowlists, time windows, approval holds, reputation compliance gates. Every payment is checked before funds move. Autonomous, and governed. Download the MCP: npmjs.com/package/@quackai/q…

Q402 is now live on @arbitrum. Your AI agent just stopped asking for gas money, on the largest Ethereum L2. Sign once, settle in USDC or USDT, no ETH required. npm install @quackai/q402-mcp. Plug it into Claude, Cursor, Cline, Codex, or any MCP client, and your agent gets gasless payments, recurring payments, and Agentic Wallets out of the box. q402.quackai.ai/

Last clinic, last chance. Don't sit on the question you've been overthinking. Our APAC Lead @phavorable is on today's @Mantle_Official fireside with @MerchantMoe_xyz and @AlloraNetwork. If you're building agents for The Turing Test Hackathon, come ask us anything: payments, autonomy, governance, whatever's blocking you. See you there✈️
You had three Mentor Clinics to bring your questions, blockers, and ideas you've been overthinking. But the fourth is where it ends, and it's your last chance to ask anything you need for The Turing Test Hackathon. We'll stay on to answer as many questions as we can ↓

Q402 Agent Wallet now supports public agent registration. With one signature, builders can mint an agent NFT on BNB Chain and link the agent wallet as the Q402 payment endpoint in metadata. From there, reputation starts building through real Q402 usage. More transactions → more activity data → more reputation. Viewable on 8004scan. Your AI agent is now trackable on-chain.

AEF SEOUL 2026 has concluded. 🎉 Quack AI APAC Lead David Lee @Phavorable kicked off the night with a keynote on "Agent Execution" — laying out a sharp vision for how AI agents will execute, settle, and operate on-chain. 11 teams took the stage at Hashed Lounge across three Research Showcase sessions, unveiling four weeks of deep R&D on AI agent payment and execution protocols. Top Team Awards were presented, with winning research to be shared publicly. 2 Insight Panels pushed the conversation further — from agent identity and trust to the rise of autonomous on-chain markets. An unforgettable evening of connection, inspiration, and exploration. Thank you to co-host @hyblock_kr, all sponsors, partners, and everyone who showed up — the Agent Economy is being defined, together. 🙌

한양대학교 기반 블록체인 학회인 @hyblock_kr@QuackAI_AI 가 주관하는 AEF SEOUL 2026에서 Agent AI에 대한 리서치 발표를 듣고 web3 현장에서 일하고 계시는 다양한 분들의 의미있는 패널토크를 듣고 왔습니다. Quack AI의 q402와 9가지 MCP에 대한 이야기부터 시작해 각 학회원들의 ai agent 레이어별 구상에 대해 굉장히 구체적인 이야기들이 오갔는데요. 개인적으로 매우 thought-provoking한 세미나였던 것 같습니다. 🙂
