Build a Decentralized Freelancing Marketplace Using Blockchain
Launch a transparent and peer-to-peer freelancing ecosystem powered by smart contracts and crypto-based escrow without centralized control or high platform fees.Traditional platforms take large cuts, delay payments, and limit global participation. A decentralized model removes intermediaries, ensures trust with smart escrow contracts, and enables freelancers to earn directly in crypto.
Develop a smart contract-enabled freelancing platform where clients can post jobs, freelancers can apply, and payment is released through an automated escrow system upon task approval, ensuring trust and transparency on both sides.
Smart Escrow Contracts
Funds are held in escrow and automatically released to freelancers after successful task completion.
Decentralized Job Listings
Clients can post jobs directly on-chain, visible to all without censorship or gatekeeping.
Crypto-Based Payments
Freelancers receive payment in ETH, MATIC, or stablecoins with instant wallet transfer.
Reputation System
Each transaction updates public ratings for both parties, stored on-chain for transparency.
Clients connect wallets and post job listings through the frontend. Freelancers submit proposals, and when selected, smart contracts lock payment in escrow. On approval, payment is released automatically. IPFS can be used for proposal storage and attachments.
