Building a Privacy-First AI Escrow DApp on Ethereum | ChainX Hackathon 2026

Description

In this video, I present my official submission for the ChainX Blockchain Hackathon 2026 — a Privacy-First AI-Powered Escrow Commerce DApp built on Ethereum. @Challengepost This project combines: • Smart Contract Escrow • AI-Based Risk Assessment • Wallet-Only Identity • Privacy-First Architecture Traditional e-commerce platforms require users to share personal data such as email, phone number, and bank details. This DApp eliminates centralized identity storage by using crypto wallets as the only identity layer. An AI model evaluates each transaction and dynamically influences escrow release decisions, improving fraud detection while preserving user privacy. Tech Stack: - Solidity (Escrow Smart Contract) - Hardhat - React + Ethers.js - Node.js Backend - FastAPI AI Risk Engine - Ethereum Sepolia Testnet This project was originally conceptualized during Fortify Labs Web3 Startup Studio and has been redeployed and optimized specifically for the ChainX Hackathon. If you’re interested in Web3, AI, Smart Contract Security, or Hackathon Builds — this video is for you.
