Build a Trustless Escrow Payment System for Freelancers

Freelance marketplaces often suffer from trust issues, late payments, and platform fees. A blockchain-based escrow system ensures that funds are locked until both parties agree on delivery—eliminating disputes and reducing reliance on centralized services.

Build a smart contract that acts as an intermediary between clients and freelancers. Funds are deposited into the contract and only released to the freelancer upon client approval or after a predefined time window, with dispute resolution fallback if necessary.

Clients create escrow contracts specifying project terms, deposit crypto, and assign a freelancer. Upon task delivery, the freelancer marks the job as done. If the client confirms within a time window, the funds are released. Otherwise, arbitration or auto-release logic kicks in.

• Solidity contracts for project initiation, fund locking, and release mechanisms
• Wallet-based role verification (client, freelancer, arbitrator)
• Frontend dashboard for job creation, submission, and approval
• Event logs for dispute history and milestone progress
• Optional IPFS for project documents or deliverables
