Build a Trustless Escrow Payment System for Freelancers
Develop a smart contract-powered platform where clients can deposit funds, and freelancers get paid automatically after task approval—ensuring fairness and security for both parties.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.
Secure Payment Holding
Client funds are locked in the smart contract and cannot be withdrawn until work is approved.
Dual Party Authorization
Funds are only released when both client and freelancer approve or a deadline is reached.
Dispute Resolution Logic
Optionally include an admin or arbitration role in case of conflicts between the two parties.
Milestone-Based Payment Support
Break down large projects into smaller deliverables, each with its own escrow transaction.
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

1. Write Escrow Smart Contract
Develop logic for initiating contracts, holding funds, and releasing payments based on confirmations.
2. Build Freelancer and Client Portals
Allow each party to monitor project status, submit work, or approve payments securely.
3. Add Arbitration and Timeout Mechanisms
Define fallback logic in case of no response or conflict using a third-party or time-lock release.
4. Enable Milestone Escrows
Let clients break large jobs into smaller payment segments with independent approval flows.
5. Test Complete Workflow on Testnet
Simulate real-world freelance tasks including delayed approvals, rejections, and dispute resolutions.
