🚀 USYC Multi-Agent DeFi System - Autonomous Commerce on Arc 💡 THE IDEA: What if AI agents could manage finances autonomously? This system enables agents to deposit USDC, earn Treasury yields via Circle's Teller, generate professional receipts, and pay for APIs/services automatically - all without human intervention. This is true agentic commerce: machines coordinating and paying machines on Arc's sub-second finality rails. 🤖 MULTI-AGENT ARCHITECTURE: VAULT AGENT: The financial brain. Monitors yield rates, executes deposits/withdrawals on YieldVaultV2, and optimizes returns automatically. Converts USDC to USYC for Treasury yield generation. MEDIA AGENT: The communication layer. When Vault Agent completes operations, Media Agent auto-generates branded PDF receipts with QR codes linking to Arc Explorer. Full transparency and audit trails. GATEWAY CLIENT: The liquidity bridge. Interfaces with Circle Gateway for cross-chain USDC transfers, real-time balance tracking, and instant settlement. X402 HANDLER: The payment protocol. Detects HTTP 402 Payment Required and pays automatically. Agents access paywalled APIs, data, and compute without human approval. ⚡ TECHNICAL STACK: - Backend: Python 3.11, FastAPI, Web3.py, HTTPX - Contracts: Solidity, UUPS proxy pattern, OpenZeppelin, Timelock - Circle: Gateway, Wallets, CCTP, Paymaster, Teller, x402 🔗 DEPLOYED INFRASTRUCTURE: - YieldVaultV2: 0x2f685b5Ef138Ac54F4CB1155A9C5922c5A58eD25 - Network: Arc Testnet - Status: ✅ Circle Whitelisted 🎯 Track: Best Gateway-Based Micropayments Integration 🏆 HIGHLIGHTS: - FIRST developer to deploy on Arc Testnet - Circle Whitelisted contracts - Direct contact with Circle team (Tim B., Sam Seeley, Corey Cooper) 👨‍💻 ABOUT: I'm AbdelAziz Moussaoui, solo developer from Paris.

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.

In this hybrid hackathon powered by Arc, developers will build the next generation of agentic commerce systems using Arc with USDC. Explore a world where AI agents and web services can pay for APIs, data, compute, and content in dynamic, usage-based ways, while Arc provides stablecoin-native settlement with predictable USDC fees and deterministic, sub-second finality. This hackathon is supported by Google & Google DeepMind, with a dedicated challenge and $40,000 in Google Cloud Platform (GCP) credits awarded for the best use of Gemini models and Google AI Studio. 📅 January 9 – 24, 2026 • Jan 9 – 23 (Online Phase) – Collaborate and build online with developers and AI innovators from around the world. All projects must be submitted by the end of the online phase on January 23rd. • Jan 23 (On‑site Build Day – San Francisco, CA) – Selected participants will be invited to an exclusive in‑person session to refine their projects and connect directly with mentors. • Jan 24 (On‑site Demos & Awards – San Francisco, CA) – Live pitching sessions to a panel of judges and ecosystem partners, followed by the official winner announcement.
