VeriChainX

VeriChainX is a shopping agent and MCP server that checks a store and its products before an AI agent buys, so agents only buy the real thing. The problem: AI shopping agents happily buy replicas and dropshipped knock-offs, and shoppers have no proof that what arrived is genuine. Ownership proof on a blockchain is powerful, but ordinary shoppers and shop owners don't understand crypto. What it does: - Every search result gets a recommended / caution / avoid label and a 0-100 scorecard (authentic, seller, quality, value, delivery), with the evidence behind it: seller identity, domain age, refund policy, reviews, replica wording and dropshipping signs. - For Shopify stores that join, a certification agent goes through the whole catalog and certifies each product that passes fixed rules: a valid GS1 barcode unique to that product, real photos, no replica wording, and the store checks. Each certificate is anchored on Solana and tied to the barcode. - Every sale of a certified product registers the item to its buyer as a numbered ownership NFT that proves it's genuine if it is ever resold. - No one needs a crypto wallet. VeriChainX mints the NFTs, holds them for buyers under their order email, and pays every network fee. Shoppers see their items by signing in with an email link and can move them to their own wallet if they want. - Shopping agents get the real delivered price from any Shopify store (shipping, tax, discounts) through Shopify's Checkout MCP, and the shopper pays on the store's own checkout. - Developers can plug the same checks into their own agents through a 12-tool MCP server with API keys and usage billing.
