Best AI & Web3 Integration
Supergig
SUPERGIG is a decentralized freelance marketplace that transforms the way companies hire and verify talent. We allow companies to search for freelancers by skills, bid for contracts, and mint skill NFTs as proof of employment. These NFTs record the job details immutably on-chain.
Freelancers build a verifiable blockchain-based profile showcasing their experience timeline, enabling better trust, transparency, and reputation. Payments are handled through escrow smart contracts, releasing funds upon job completion.
How it was built
We built this project using a full-stack Web3 architecture:
Smart Contracts:
SkillNFT_And_Escrow.sol manages skill NFT minting, escrow payments, and release logic.
Talents.sol stores freelancer profile metadata (name, wallet, profile ID).
Frontend:
React + TypeScript with Tailwind + ShadCN UI.
Pages: Search, Profile, Offers, Contract Signing.
Backend:
Node.js + Express + TypeScript.
REST APIs for talent search, profile retrieval, and CRON tasks for job monitoring.
Blockchain & Tooling:
Hardhat for local development and Sepolia for deployment.
Ethers.js for contract interaction.
NFTs deployed using ERC721.
