Supergig

A decentralized freelance marketplace with verified talent

Supergig

About the Project

SUPERGIG is a decentralized freelance marketplace that transforms the way companies hire and verify talent. Companies can 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..
