Blockchain / Mobile Platform

Zeal

An end-to-end NFT authenticity platform for brand protection with blockchain-based minting and verification, secure backend APIs, and a companion mobile app.

Project overview

Zeal connects physical products to verifiable digital identities. Brands can mint authenticity records, while customers can scan and validate product provenance through a mobile experience.

What I worked on

Designed the product authenticity flow from minting through verification.
Structured secure backend APIs for product and verification records.
Planned the mobile scanning experience for fast customer validation.

Implementation snippet

A look at the solution

const verifyProduct = async (tokenId) => {
  const product = await contract.products(tokenId);

  return {
    authentic: product.owner !== ethers.ZeroAddress,
    productId: product.id,
    mintedAt: product.mintedAt,
  };
};
