AgentFlow is an agentic economy built natively on Arc Network using Circle's full infrastructure stack. It features 14 specialized AI agents — research, analyst, writer, swap, vault, bridge, portfolio, invoice, vision, transcribe, schedule, split, batch, and ASCII — each registered with an ERC-8004 onchain identity and earning USDC for every task they complete. Every agent interaction triggers real x402 nanopayments via Circle Gateway, enabling sub-cent per-task pricing that would be economically impossible on traditional blockchains. When a user requests research, the Research Agent pays the Analyst Agent pays the Writer Agent — all in real-time USDC on Arc, settling at $0.000001 gas cost per transaction vs $0.50-2.00 on Ethereum. AgentFlow proves 9 distinct agent-to-agent payment chains, 60+ onchain transactions in 34 seconds, and 99.995% margin improvement over Ethereum gas costs. Built with Circle DCW for all execution, Circle Gateway for nanopayments, Circle Bridge Kit for cross-chain USDC, and an agent treasury that auto-tops-up agent wallets to keep the economy running. The system also includes a Telegram bot with full x402 nanopayment support, an economy dashboard showing live A2A payment flows, and an address book for human-readable payment routing.

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.
