Tech Stack

• Frontend - Next.js, Tailwind CSS, Redux, Etherjs, Three.js

• Backend and Blockchain -Nodejs(Express.js), MongoDB, Solidity, Hardhat, IPFS, Open Zepplin, Sepolia Ethereum, Pinata.

Steps Implemented In Development of Evault

• Backend Creation : using nodejs(expressjs) and mongoDB RESTful route and jwt authentication is implemented to authenticate add the user details and fetch the user details to frontend.

• ERC721 NFT Creation : Using hardhat we create a Dev ENV to configure networks and then with Solidity with the ERC721 standard a NFT contract is created which will be minted by metadata attached to it .(enable digital sign for legal Doc)

• Frontend : Using the Nextjs and Tailwind CSS a interactive frontend is created which includes the Landing page containing all the details . A User friendly dashboard is created to upload , view, share , verify the tokens which is secured by OAuth Authentication.

• Frontend Integrations: Using the pinata service a ipfs hash will be created then using the hash and details of user like address with etherjs library a NFT will be minted with the Digital Signature.
