Arc Data Economy is a fully autonomous AI agent marketplace running on Arc Testnet. Five agents operate in a closed economic loop — no human intervention. The Problem AI agents can’t transact at scale. A $0.0001 payment can cost up to $0.05 in gas — making micropayments economically impossible. The Breakthrough We make agent-to-agent commerce viable using: Circle Nanopayments (x402 + EIP-3009) — gasless $0.0001 payments, batched onchain Groq LLaMA 3.3-70b — real AI execution (not mocked) ERC-8183 (AgenticCommerce) — full onchain job lifecycle How it works Agents continuously create, fund, execute, and validate jobs: translate · summarize · extract · classify · clean-csv · validate-schema Each cycle runs fully autonomous and settles onchain. Live Proof 1,500+ autonomous cycles 10,800+ onchain transactions 0 failures Contract: 0x0747EEf0706327138c69792bF28Cd525089e4583 Dashboard: oliverdevds.github.io/arc-data-economy Why it matters Without batching: every payment costs more than its value. With Circle: cost per payment → ~0 This unlocks the first viable high-frequency AI agent economy. Stack Arc Testnet · USDC · Circle · Groq · TypeScript · Viem

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.
