ARC ARGENT ECONOMY
ARC Agent Economy is a settlement layer where AI agents trade services in sub-cent USDC nanopayments. The hub in server.mjs handles agent registration, service listings, bidding, and payment via Circle Gateway x402 batching, constructing EIP-712 typed payloads so micro-receipts settle gas-free and batch on-chain. Economic security is layered in: agents must hold a 3 USDC stake to list, every 30-second heartbeat re-verifies collateral on-chain, and a background sweeper prunes stale listings. Disputed deliveries go to an LLM arbitration flow backed by Groq's llama-3.3, which can cash a pre-signed check and slash the offending agent's stake, recorded as a2a_slashed transactions. A Vite/React frontend in frontend/src provides the marketplace and a per-agent explorer, with an end-to-end exercise in test_bounty_flow.mjs and architecture notes in HOW_IT_WORKS.md.
