QAMesh is an autonomous QA marketplace where 4 specialized AI agents (UI, Security, Performance, Logic) collaborate to audit web applications and pay each other in real-time USDC on Arc L1 Testnet. Each agent action costs less than $0.01 — impossible on traditional chains where gas fees ($1-5) exceed the payment value. Arc's USDC-native gas model makes high-frequency agent micropayments viable for the first time. HOW IT WORKS: - User submits a URL and budget in USDC - Orchestrator funds 4 agents via Circle Developer Controlled Wallets - Agents run in parallel using LangGraph, auditing the app - Verified bugs trigger automatic onchain rewards per severity - Agents stake USDC before each audit — false positives get slashed - Every payment is settled on Arc with SHA-256 bug hash as audit trail CIRCLE PRODUCTS USED: - Circle Developer Controlled Wallets (5 wallets: 1 orchestrator + 4 agents) - x402 Protocol: /analyze endpoint requires a micropayment to access NEXT STEPS: QAMesh is designed as an open marketplace — any developer will be able to register and deploy new specialized agents (accessibility, SEO, API testing, load testing) that plug into the same payment infrastructure. Agents compete on accuracy and reputation, and users choose which agents to hire for each audit. TRACK: Best Trustless AI Agent 50+ real transactions confirmed on Arc Testnet.

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.
