Nature NFTs Marketplace


NFT Factory and Marketplace for Nature Photographs 

Nature NFTs Marketplace was built during the April, 2022 ETHGlobal DAOHacks hackathon where it won two prizes. The prizes included a successful L2 deployment to Polygon and the use of IPFS for image and metadata deployment from Protocol Labs. The dApp allows the user to pin an image and metadata including name, description and URI to IPFS, then adds this metadata to the Polygon mainnet blockchain. The newly minted, on-chain NFT is then listed as an item for sale on the platform. The NFT will also render on Opensea.io and Rarible.com when connecting your Ethereum wallet (i.e. Metamask, Wallet Connect, Trezor, or Ledger) that holds the NFT.  The dApp was created using Hardhat for contract deployment to Polygon, IPFS to store the image and metadata, Moralis for the Web3 connection with Metamask and a Next.js front-end that showcases the beauty of nature NFT images. We will be deploying the app to Ethereum mainnet in early November, 2022.

McKurz Decentralized Exchange


Decentralized Digital Asset Exchange

The McKurz Decentralized Exchange (DEX) allows users to trade digital assets on the Sepolia Ethereum blockchain for Sepolia ETH tokens. This DEX ensures self-custody of your tokens, meaning the exchange smart contract holds your tokens only while you have active orders. Your tokens remain securely held in the smart contract until you withdraw them, offering a safer alternative to centralized exchanges where you relinquish control of your assets and must trust the exchange to facilitate trades and withdrawals. There have been instances of centralized exchanges failing to return customer assets, a risk mitigated by using a DEX.

To access the McKurz DEX and make trades, you need a Metamask or Phantom wallet funded with Sepolia ETH. If you need to fund your wallet, Quicknode and Alchemy both offer Sepolia faucets where you can obtain Sepolia ETH.

Legal Documents Marketplace

Legal document templates as an NFT marketplace

The Legal Document Form Repository will be a datastore and marketplace to purchase common filable-PDF legal documents such as a simple will, articles of incorporation for specific states or provinces, bill of sale sample, building contract, business plan, etc. Currently, the legal documents are stored as .jpg files, but in future iterations, the documents will be filable-PDFs so that the user can use it for their own purposes and fill them with their own unique information. The legal documents are stored on IPFS and deployed to the Rinkeby Ethereum testnet as ERC721 NFTs. A live demo can be found at: https://legaldoc.surge.sh/.

Why is decentralized better than centralized?

Digital assets currently trade on mostly centralized exchanges where investors need to trust that orders to buy and sell are being treated fairly and their assets are being held safely.  Our products allow for customers to participate on a trustless, decentralized platform where there is no centralized entity controlling prices to their advantage.  Our decentralized exchange (DEX) also provides self-directed management of your assets.

Centralized exchanges have been hacked many times over the last 9 years since Bitcoin began trading.  Customers have lost hundreds of millions of $USD worth of digital assets as a result.  How could this have been avoided? When using a decentralized exchange, your assets are only on the exchange for very brief periods of time, therefore eliminating most of the risk of being the victim of a hack.

These are crucially important considerations when choosing a digital asset exchange.
