PennyPilot is a spend-control card for AI finance agents. It lets an agent buy small paid data proofs, such as KYB, sanctions, invoice, risk, FX, and identity checks, while staying inside a strict user-defined USDC budget and per-call spending cap. The project uses Circle Gateway x402 for sub-cent payments and Arc Testnet for transparent on-chain receipt anchoring Instead of asking the user to approve every tiny proof separately, PennyPilot supports a batch flow: the user selects how many proofs the agent may purchase, signs one payment authorization, and the app records provider-signed receipts for the full batch. This creates a practical payment pattern for AI agents that need to make many small autonomous purchasing decisions PennyPilot demonstrates why nano-payments matter: each paid action is below $0.01, making traditional card or subscription flows too expensive and too slow

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.
