LedgerLens is an invoice-risk copilot for finance and procurement teams. Before a vendor payment is approved, the agent buys specialist verification checks one by one: OCR extraction, duplicate invoice detection, policy validation, tax checks, vendor-risk screening, and line-item review. Each check is priced below one cent and paid through x402 and Circle Gateway Nanopayments, making high-frequency machine-to-machine finance workflows economically viable. For proof, LedgerLens records successful usage receipts on Arc, giving judges and operators a visible audit trail. In the demo, a suspicious invoice can trigger a 12-check quick audit or a 60-check volume run, showing both the business decision and the margin gap versus direct per-check settlement.

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.
