AgriSync is an agricultural intelligence platform for smallholder farmers across Africa's 54 nations. Two problems destroy farm income every season: 1. Crop disease goes undiagnosed — the nearest agronomist is hours away or unaffordable. A farmer watches their maize develop grey leaf spot and doesn't know whether to spray, wait, or replant. 2. Farmers sell at the wrong market — without real-time price data, a farmer in Nakuru may sell tomatoes locally for KES 20/kg when Nairobi is paying KES 31/kg that same morning. On 500 kg that's KES 5,500 lost to information asymmetry. AgriSync solves both in one flow. A farmer takes a photo of their crop leaf with any smartphone. Our two-stage vision pipeline — Llama-3.2-11B-Vision-Instruct as primary, with LLaVA-v1.5-7B (fine-tuned on plant diseases) as specialist fallback, both running on AMD MI300X — identifies the disease, severity level, and the specific PCPB-approved chemical available at the nearest agro-vet, with the price in KES. At the same time, our ArbitrageEngine agent queries crop prices across African market hubs, calculates net profit after transport costs, and recommends the single best market to sell at today. The OrchestratorAgent (Mistral-7B-Instruct) combines both outputs into a bilingual English and Swahili advisory. For farmers without a smartphone, the same advisory is delivered as a 160-character SMS via Africa's Talking API. The platform covers diseases across major African food crops: Tomato Late Blight, Maize Gray Leaf Spot, Cassava Mosaic Disease, Fall Armyworm, Groundnut Rosette, Rice Yellow Mottle Virus, Bean Angular Leaf Spot, Potato Late Blight, and more.

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.
