Blockchain-Powered Freelancing Platform
Why Choose This Project?
Traditional freelancing platforms like Upwork or Fiverr charge high commission fees, suffer from delayed payments, and depend heavily on centralized authority to resolve disputes — which may be biased or manipulated.
This Blockchain-Powered Freelancing Platform removes intermediaries and builds trust through smart contracts. It ensures transparent agreements, automated payments, and dispute resolution on a tamper-proof ledger, giving both freelancers and clients more control over their work.
This project showcases an innovative Web3 use-case, combining blockchain, smart contracts, and decentralized payments — a perfect blend of real-world application and modern tech stack.
