Freelance Marketplace with Smart-Contract Escrow

Why Choose This Project?

Traditional freelance marketplaces often take high commissions, control payments, and act as intermediaries, leaving both freelancers and clients dependent on the platform. This blockchain-based freelance marketplace uses smart contract escrow to secure payments, ensuring trust, transparency, and fair transactions. Freelancers get paid promptly upon milestone completion, and clients are protected from non-delivery.
