Aura-Arc is a professional-grade economic engine built to solve the fundamental "Unit Economics" crisis of autonomous agents. On legacy blockchains, a $0.005 task costs $0.15 in gas—a 3,000% overhead that makes agentic micro-commerce impossible. Aura-Arc leverages the Arc L1 to reduce this to $0.0009, securing a +91.20% net profit margin. Architected by a solo 16-year-old from Shabgram, Bogura, Bangladesh, Aura-Arc moves past simple "wrappers" by implementing a deterministic C++17 core compiled to WebAssembly. This ensures financial atomicity independent of the JS main thread. To solve the "Trust Gap," we introduced the ASE (Atomic Settlement & Escrow) Protocol—a 3-way cryptographic handshake ensuring agents only get paid upon verified task fulfillment. For industrial reliability, Aura-Arc implements "Beast Mode" state rehydration. By synchronizing a Wasm MemoryStore with a Supabase Singleton Ledger, the system survives crashes and re-injects historical state into native registers upon reload. This is not just a demo; it is a scalable, resilient operating system for the next generation of the internet.

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.
