FreelanceArc is a decentralized freelance marketplace built on Arc Network where every job is a smart contract and every payment is USDC locked in escrow — no platform, no middleman, no trust required. The problem: Upwork made $618 million in fees last year. All of that money came from freelancers and clients. We replaced that trust layer with 4 smart contract calls. The full job lifecycle runs on-chain via ERC-8183: 1. Client posts a job → createJob() opens the contract, fund() locks USDC in escrow. The client cannot touch the funds. 2. Freelancer applies → submits wallet address and cover letter. 3. Freelancer delivers → submit() records cryptographic proof of delivery on-chain permanently. 4. Client approves → complete() fires, USDC transfers automatically to the freelancer's wallet. Every step is a real transaction on ArcScan. Not mock data. Real USDC, real contracts. Why Arc Network: → ERC-8183 gives job lifecycles a native standard — we didn't build escrow from scratch, it's in the protocol. → USDC as gas means stable, predictable transaction costs. → Circle Developer Controlled Wallets provide enterprise-grade infrastructure without private key complexity. Result: total platform fee ~0.006 USDC per transaction. On a $500 job, Upwork takes $100. FreelanceArc takes six cents. We also built an Agent-to-Agent Commerce demo where two Claude AI agents interact autonomously on Arc — one posts a job and locks USDC, the other completes the work and collects payment. Zero human involvement. This is exactly what ERC-8183 was designed for. Live: freelance-arc.vercel.app Agent Demo: freelance-arc.vercel.app/agent-demo GitHub: github.com/bayrakdarerdem/freelance-arc

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.
