Mintaro is a Web3 freelance platform prototype built around milestone-based escrow payments.
It ensures freelancers are rewarded fairly for completed work while giving clients protection if projects stall or are abandoned.
This MVP is deployed on Avalanche Fuji Testnet.
- Milestone-based escrow — fund and release project step-by-step
- Pull payment model — freelancers withdraw earned funds themselves (safer than push payouts)
- Dispute mechanism — cancellation requests, freelancer confirmations, and owner resolution
- Platform fee system — configurable by owner (10 bps = 0.1%)
- Multi-token support — works with AVAX + ERC20 tokens
- Admin controls — pause/unpause, update treasury, adjust fee rates
- Smart Contracts: Solidity, Hardhat
- Frontend: React, Vite, TailwindCSS
- Web3 Integration: Wagmi, RainbowKit
- Deployment: Avalanche Fuji Testnet
- Infra Roadmap: On-chain reputation & scoring, DAO-based dispute governance, Layer-2 scaling for cheaper escrow, WalletConnect integration improvements

- Client creates escrow with milestones + deposits funds
- Freelancer completes work → submits for approval
- Client approves milestone → freelancer balance updates
- Freelancer withdraws funds anytime
- Disputes: client requests cancel → freelancer confirms OR owner resolves
- Reputation system — combined on-chain scoring + off-chain verifiable proof
- DAO governance — community-driven fee & treasury settings
- Cross-chain escrow — Avalanche ↔ Ethereum ↔ L2 support
- AI integration — automatic milestone verification, fraud detection
- Advanced dispute resolution — third-party arbitrators + DAO voting
- Fiat on/off ramps — smoother Web2 → Web3 user experience
- Mobile-first dApp — freelancers/clients manage work on-the-go
