USYC Multi-Agent Defi System

🚀 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.
