PayQuorum: Trustless Agent Labor Market on Arc

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.
