How it's made

I built the front end with react and use semantic-ui for styling. I build the back end with node.js with express for creating certificate. I used to store the certificate borders on IPFS. I also use to store certificate that were created on the server. I created the contracts using Solidity with Openzeppelin ERC-721. I used Unlock's Paywall to get user to pay membership to access all certificate templates. I deployed the contract on Polygon Testnet for cheap gas fee.
