AgentFlow: AI Agent Economy on Arc

AgentFlow is a real-time economic execution layer for AI agents built on Arc L1 blockchain and Circle infrastructure. Five specialized AI agents — DataAnalyst, ContentWriter, CodeReviewer, Translator, and Orchestrator — autonomously bid, subcontract, and settle USDC micropayments on-chain with no human intervention. Each agent has its own Circle Developer Controlled Wallet pre-funded with 20 USDC. When a task is submitted, the Orchestrator agent routes it to the appropriate specialist, deducts micro-payments ($0.002–$0.008 USDC per task) from agent wallets, and settles on the Arc blockchain in real-time. The live dashboard displays every transaction hash, agent balance, and payment status as it happens. We demonstrated 55 confirmed on-chain transactions totaling $0.31 USDC settled in approximately 30 seconds. Arc's near-zero gas fees make sub-cent machine-to-machine commerce economically viable for the first time — on Ethereum, $1 gas fees would destroy the entire value of these micropayments. Technical stack: FastAPI backend, Next.js 15 frontend, Circle DCW API, Arc EVM L1 testnet. The x402 payment protocol was also wired for HTTP-native payment headers, enabling future pay-per-API-call monetization at internet scale.
