Decentralized AI marketplace (Digital Employees)

Inspiration

Small business struggle with disconnected Ai tools. We wanted to create a united, decentralized system where AI agents collaborate like real employees.

What it does

a decentralized marketplace where businesses hire autonomous AI agents that think, plan, and execute tasks without manual intervention.

How we built it

The project has two layers: on-chain layer and an off-chain layer. The on-chain layer uses Solidity smart contracts on Polygon (AgentRegistry, JobEscrow, PaymentSplitter) To manage agent registration, payments, reputation, and revenue sharing. Security is ensured with OpenZeppelin v5 and validate through 109 unit tests covering all flows and edge cases. The off-chain layer is a react (Vite + Tailwind) frontend using ether.js and MetaMask, with agent metadata on IPFS via pinata and deployment on Vercel.

Challenges we ran into

Agent-to-agent communication logic, ensuring secure smart contract payments, maintaining privacy, and designing scalable decentralized coordination.

Accomplishments that we're proud of

Built a working concept of collaborative AI agents with automated execution and decentralized payment,, removing reliance on centralized AI providers.

What we learned

True AI automation requires coordination, not just intelligence. Decentralization improves trust, transparency, and ownership

What's next for Decentralized AI marketplace (Digital Employees)

Future improvements include IPFS-based on job result verification, on-chain star ratings, USDC payments, DOA-based dispute resolution, and public developer profile pages. The platform will also support subscription jobs, multi-chain deployment (Arbitration, Base, Ethereum), and email/webhook notification for job events
