PayQuorum is a trustless agent task marketplace where 5 autonomous AI agents form a self-governing micro-economy on Arc. THE PROBLEM: AI agents need to transact at sub-cent scale. Ethereum gas ($0.50/tx) makes $0.005 payments impossible. Even L2 gas erodes 100-400% of margin. Autonomous agent economies cannot exist without gasless settlement. THE SOLUTION: PayQuorum implements the full economic stack for agent-to-agent commerce: • Orchestrator Agent posts tasks with USDC bounties locked in on-chain escrow • Data Agent fetches real financial data from AIsa APIs via x402 micropayments ($0.005/call) • Compute Agent analyzes data using Google Gemini 2.5 Flash • Validator Agent scores output quality (100-point scale) and triggers escrow release • Treasury Agent enforces on-chain budget limits per agent per day 4 custom Solidity smart contracts deployed and verified on Arc Testnet: - TaskRegistry: https://testnet.arcscan.app/address/0x2Ec3180e23AC9C82205cb3Cd6885f2a27543E291#code - AgentEscrow: https://testnet.arcscan.app/address/0xC79BE48Cf33bA378fD6826cBAEbBaC6f0D05c389#code - Reputation: https://testnet.arcscan.app/address/0xfB225D66f7627F2e0a39A8F0D927253F6fF8A9CB#code - BudgetController: https://testnet.arcscan.app/address/0x571eC845335B89985Be599dD6Bd40b77B072C455#code Each demo cycle generates 8 real on-chain transactions using ALL 4 contracts. Running 8 cycles produces 64+ verifiable transactions on ArcScan. MARGIN PROOF: 64 transactions at $0.005/action generates $0.32 revenue. Ethereum L1 gas would cost $32 (100x revenue). Arc + Nanopayments: $0.64 gas. Only Arc makes this viable. ERC-8004 compliant agent registration at /.well-known/agent-catalog.json. Budget controls configurable from the dashboard UI with real on-chain enforcement. Built with: Arc, USDC, Circle Nanopayments, x402, Gemini 2.5 Flash, Featherless AI, Solidity, Next.js, Hardhat, viem.

In this hybrid hackathon powered by Arc and Circle, developers will build the next generation of Agentic economic applications using Circle’s Nanopayments infrastructure with settlement on Arc in USDC. For the first time, high-frequency, usage-based transactions between users, APIs, and AI agents can operate without gas overhead eroding margin. Arc provides stablecoin-native settlement with predictable, dollar-denominated USDC fees and deterministic, sub-second finality — enabling real-time coordination and economically viable per-action pricing at scale. 📅 April 20 – 26, 2026 • Apr 20 – 25 (Online): Submit projects by Apr 25. • Apr 25 (On-site Build – SF, CA): Teams refine projects. • Apr 26 (On-site Demos & Awards – SF, CA): Live pitches & winners announced.

In this hybrid hackathon powered by Arc, developers will build the next generation of agentic commerce systems using Arc with USDC. Explore a world where AI agents and web services can pay for APIs, data, compute, and content in dynamic, usage-based ways, while Arc provides stablecoin-native settlement with predictable USDC fees and deterministic, sub-second finality. This hackathon is supported by Google & Google DeepMind, with a dedicated challenge and $40,000 in Google Cloud Platform (GCP) credits awarded for the best use of Gemini models and Google AI Studio. 📅 January 9 – 24, 2026 • Jan 9 – 23 (Online Phase) – Collaborate and build online with developers and AI innovators from around the world. All projects must be submitted by the end of the online phase on January 23rd. • Jan 23 (On‑site Build Day – San Francisco, CA) – Selected participants will be invited to an exclusive in‑person session to refine their projects and connect directly with mentors. • Jan 24 (On‑site Demos & Awards – San Francisco, CA) – Live pitching sessions to a panel of judges and ecosystem partners, followed by the official winner announcement. Get guidance from Arc and Circle experts through on-site support. 📍 On-site Venue (Jan 23–24): MindsDB SF AI Collective 3154 17th St, San Francisco, California, USA 🤝 Go solo or team up, it's your flow. 🏆Compete for $50,000 in USDC & GCP Credits. 📍 On-site participation is by invitation only.
