The Opportunity

Problem

Web3 freelancers experience burnout from the constant hustle required to chase payments from DAOs and NFT projects that ghost them after milestone delivery.

Solution

Freelancers mint NFT proofs for completed milestones, creating public reputation trails that DAOs honor. Automated payment links tie proofs to invoices for instant settlement. Eliminate burnout by shifting leverage to verifiable on-chain delivery.

Target Audience

Web3 freelancers contracting with DAOs and NFT projects

Differentiator

NFT-based proof system builds freelancer moat with portable rep across DAOs.
