Nature NFTs Marketplace

https://nature-nfts-marketplace-polygon.vercel.app/

The Nature NFT Marketplace is an NFT factory deployed on the Polygon Mainnet blockchain. It allows users to create their own NFT from a digital image, list it for sale on the marketplace, and actively trade all users' NFT listings. It was built with an Ethereum smart contract that adds the previously mentioned functionality. I have deployed the app to the Polygon and Arbitrum blockchains in an effort to lower transaction "gas" fees.

Decentralized Token Exchange

https://mckurz-dex.vercel.app/

The McKurz cryptocurrency exchange dApp was launched on the Ethereum Kovan Test Network in August 2020. It has since been upgraded to the Goerli testnet as a result of the Ethereum Merge and the deprecation of the Kovan chain. The exchange allows users to list buy and sell orders of different cryptocurrencies. The app is an older production and works best with unlocking Metamask with your password, refreshing the browser after connection, and a possible manual connection to the Metamask Goerli wallet (update shortly).

Safe Harbour Finance Reward Coin Staking App Deployed to zkSync

https://safeharbour-finance.vercel.app/

The Safe Harbour Finance app allows users to stake native SAFE tokens and acquire rewards of the platform's native SAFE token. The app's uniqueness is that it is deployed to the zkSync testnet 2.0, where costs of staking, transfer, lending, or borrowing are quite inexpensive and secure. To use the app, you will need to add the 'zkSync alpha testnet' to Metamask. Directions for this process can be found at:

Demonstrations of the app are available.
