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.

InsightX revolutionizes how people access AI-powered research by eliminating expensive subscription models in favor of micropayments. Built on Arc Network with Circle's x402 SDK, InsightX enables users to pay just $0.01 USDC per research query with zero gas fees. The Problem We Solve: Traditional research and AI tools require monthly subscriptions that waste money when usage is sporadic. Additionally, blockchain-based alternatives are often too complex for mainstream users, requiring management of seed phrases and gas fees that can exceed the actual payment amount for small transactions. Our Solution: InsightX combines the power of AI research generation with frictionless blockchain payments through: 1. Pay-Per-Query Pricing: $0.01 USDC per research request - pay only for what you use 2. Gasless Transactions: Circle's x402 protocol handles payments seamlessly without gas fees 3. User-Friendly Wallets: Circle MPC wallets protected by a simple 6-digit PIN, no seed phrases 4. Instant AI Research: Google Gemini-powered comprehensive research in seconds 5. Permanent Storage: Research stored on IPFS for immutable records 6. Document Export: Download results as PDF or Word documents How It Works: Users register with their email and set a PIN to create a secure Circle wallet. After funding with USDC, they can submit any research query. The x402 protocol automatically handles the $0.01 payment in the background - users never see gas fees or complex transaction approvals. Within seconds, Gemini AI generates comprehensive research including key findings, trends, and implications. Circle Integration: We use Circle Programmable Wallets for user-controlled MPC wallets with email registration and PIN protection. The Circle Web3 SDK handles frontend authentication and the x402 batching middleware enables gasless payments. Every research query triggers an automatic $0.01 USDC payment through the x402 protocol without any gas fees for users.

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.
