ModelMarket on Arc solves a single hard problem for the agentic economy: per-call billing for AI models has been economically impossible. On Ethereum mainnet, a single USDC transfer costs ~$2.40 in gas. Charging $0.001 per call loses $2.399. Even L2s leave cents of overhead. Result: every API stays on monthly billing, and AI agents can never pay each other in real time. Arc changes that. USDC is the native gas token. Gas per transfer: ~$0.0001. A $0.001 call now nets $0.0009 — 90% margin. Per-call pricing finally clears. ModelMarket is the proof-of-concept marketplace. Six sellers list inference at $0.0005–$0.008 per call: Google Gemini 2.5 Flash and Gemini 2.5 Pro (cloud frontier models), Gemma 2 2B and Llama 3.2 1B running locally via Ollama (anyone with a laptop becomes a seller), Llama 3.3 70B via HuggingFace Fireworks (open-weights premium), and a deterministic NL→Shell endpoint. A buyer agent fires 60+ inference calls across all six in under 15 seconds. Each is a real HTTP 402 → EIP-3009 sign → on-chain USDC settlement → 200 response loop. The dashboard shows live earnings per seller, updating every second. We integrated Circle Nanopayments (x402 protocol), Arc testnet, USDC, Circle Wallets (developer-controlled), and Circle Developer Console. The Gemma local seller proves the bigger vision: the agentic economy is not just frontier APIs charging agents — it's anyone monetizing local compute, paid in USDC, settled on Arc. Stripe-shaped DX: drop-in middleware on the seller, drop-in axios interceptor on the buyer. Arc is the only chain where this clears. ModelMarket is the proof.

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.
