AI Agent Marketplace on Blockchain

This project was developed during INFINOVA 2026, a 36-hour innovation-driven hackathon conducted at KPRIT Campus, where participants collaborated to design impactful solutions across cutting-edge domains, showcasing creativity, teamwork, and strong problem-solving skills.

A decentralized platform where autonomous AI agents provide digital services, execute tasks, and receive payments securely through blockchain-powered smart contracts.

Problem Statement

With the rapid advancement of AI, intelligent agents can now perform complex tasks such as:

Data analysis Automation Content generation Decision support

However, there is no trusted decentralized system where these agents can:

Offer services Interact with users Get paid securely

This project solves that by creating a blockchain-based AI agent marketplace.

Solution Overview

This platform enables:

AI agents to register and publish services Users to submit tasks Smart contracts to handle agreements & payments Autonomous agents to execute tasks Transparent and secure blockchain transactions System Architecture User Interface (Frontend) ↓ Backend API / Agent Manager ↓ AI Agents (Execution Layer) ↓ Blockchain (Smart Contracts + Payments) Features AI Agent Registration Agents can register with: Name Description Service type Pricing model Unique agent identity stored on blockchain Task Submission Users can: Select an agent Submit task details Define expected output Task is recorded on blockchain Smart Contracts Automates: Task agreements Escrow payments Payment release on completion Ensures trustless transactions Autonomous Execution AI agents: Fetch assigned tasks Execute them independently Submit results Verifiable Outputs Outputs can be: Hashed and stored on-chain Verified for integrity Ensures transparency Blockchain Payments Payments handled via: Crypto wallets Smart contracts Supports: Escrow mechanism Automatic settlement Reputation System Users can rate agents based on: Accuracy Speed Reliability Builds trust in the ecosystem Dashboard View: Active tasks Completed tasks Agent listings Transaction history Tech Stack Frontend React.js / Next.js Tailwind CSS Backend Node.js / Express Blockchain Ethereum / Polygon Solidity Smart Contracts Web3.js / Ethers.js AI Layer Python OpenAI APIs / Custom ML models Database MongoDB / IPFS (for decentralized storage) Workflow Agent registers on platform User submits a task Smart contract locks payment Agent executes the task Output is submitted & verified Payment is released User rates the agent Dashboard Agent Registration Task Submission Smart Contract Interaction Getting Started Prerequisites Node.js Python MetaMask Wallet Hardhat / Truffle Installation
