A Web3 Dapp deployed on Optimistic Ethereum to mint, transfer and explore NFT rewards for the participants of 30-Days of Web3.0. https://absorbing-title.surge.sh 👀
It's a hackathon, and an opportunity to work with your peers, ship a project, and gain hands-on Web3 experience in small, collaborative, focused cohorts. 🐦 See on Twitter.
📅 Cohort #0, named Genesis, spanned over 4 weeks in Januaray 2022.
This repository contains the work of one team of the Genesis cohort, composed of @kethcode, @xavierbrochard, and @Larkef.
We built this decentralized application (Solidity smart contracts + frontend + NFT artwork), and deployed it on the Optimistic Ethereum blockchain. This Dapp lets the hackathon's admins mint and distribute NFT rewards to all hackathons participants. It also includes a hall of fame to explore all NFTs minted this way.
The main Solidity smart contract is ./packages/hardhat/contracts/NFT30Web3.sol. It extends this generic ERC721 token smart contract.
The method mint mints and transfers a new NFT to the specified address. It can only be called by an admin, and this is handled by the underlying smart contract ./packages/hardhat/contracts/Adminlist.sol
The method tokenURI is a view that renders an existing NFT, based on its id. The rendering takes place in the underliyng smart contract ./packages/hardhat/contracts/Renderer.sol.
A React application, using eth-hooks to interface with any EVM-compatible blockain.
It's composed of 3 main views:
/badge:
/hall:
/mint:
The frontend static assets are deployed on surge.sh, using:
yarn surgeThe NFT artwork is a fully on-chain SVG. Its main color is pseudo-randomly computed at mint time, creating a unique visual for each holder.
As the the main smart contract is an extension of a ERC721 token smart contract, and it implements a method contractURI, it's 'listable on public NFT marketplaces like OpenSea and Quixotic.
Since the Dapp is deployed on Optimistic Ethereum, we listed the collection on Quixotic. Take at look at it here! 👀
