AgentPay: AI Agents Trading USDC on Arc

AgentPay demonstrates the first economically rational agent-to-agent payment network built on Arc Network with Circle's infrastructure. The Problem: AI agents need to transact autonomously, but blockchain gas costs make sub-cent payments impossible. A $0.002 data request costs $0.50+ in Ethereum gas — destroying the economics of agent commerce. The Solution: On Arc Network, USDC is the native gas token with costs under $0.0001 per transaction. Combined with Circle Programmable Wallets, agents can pay each other profitably at sub-cent levels. How It Works: Two autonomous AI agents — DataAgent and AnalysisAgent — operate in a continuous payment loop: 1. AnalysisAgent needs market intelligence and discovers DataAgent 2. AnalysisAgent pays DataAgent $0.002 USDC via Circle Programmable Wallets on Arc 3. DataAgent fetches real-time crypto prices (BTC, ETH, SOL, DOGE) and uses Gemini AI to summarize insights 4. AnalysisAgent receives the data, runs Gemini AI risk analysis, and produces a BUY/HOLD/SELL recommendation 5. Each cycle generates a verified on-chain USDC transaction Our live demo completed 50+ on-chain transactions with $0.10+ USDC moved autonomously between agents — proving economic viability at scale. The margin math is clear: - Ethereum L1: $0.50-$5.00 gas (250x more than the payment itself) - Polygon: $0.01-$0.05 gas (5-25x more) - Base/Arbitrum: $0.005-$0.02 (marginal) - Arc Network: <$0.0001 gas (20x less than payment) — the only chain where this works Built with Circle Programmable Wallets (developer-controlled), Arc Network testnet, and Gemini 2.0 Flash via Google AI Studio. The Control Room dashboard shows real-time agent status, live transaction feed with on-chain verification, and a gas cost comparison table. This architecture scales to thousands of agents in an autonomous economy — each paying for exactly what they consume, settled instantly in USDC on Arc.
