Full-stack, production-ready application that combines intelligent document management with AI-powered conversations. Upload documents in multiple formats, automatically process and index them, then have natural language conversations about its content

CartLens is a high-fidelity, AI-powered shopping companion designed to orchestrate the "Spending DNA" of modern consumers. It leverages a sophisticated multimodal AI stack and an agentic orchestration layer to transform physical grocery data into a sovereign economic protocol. The system utilizes a proactive "Vision-to-State" heuristic where Gemini 2.0 Flash performs real-time structural extraction of SKUs and prices from receipt pixels. This data is autonomously processed by the Lattice Oracle—an agent built on the Google ADK—which audits the scan against a crowdsourced Global Lattice to determine its economic value. To incentivize high-fidelity data contribution, the platform implements a precision reward system: a $0.10 "Lattice-Beater" Reward for prices strictly lower than the regional record, and a $0.05 "NEW" Reward for contributing previously unmapped items. These micro-payments are settled individually via Circle Nanopayments on the Arc Testnet, proving that sub-cent transaction costs can finally make high-frequency data crowdsourcing profitable. Every verified trip concludes with the autonomous minting of a "Proof of Procurement" NFT. This NFT encodes a high-fidelity base64 image of the digital receipt directly onto the blockchain, providing permanent, verifiable evidence of the user's contribution to the global intelligence layer. CartLens effectively bridges the gap between physical retail reality and the agentic economy.

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.
