CloseSea - the Smallest NFT Marketplace

I developed and deployed CloseSea: the smallest NFT marketplace :) based on the great tutorial by Nader Dabit.

I added a few things on top of Nader’s tutorial:

• how to add NFT traits in metadata and how they will be displayed on OpenSea
• how to manage the contract as a owner, e.g., change the listing fee and withdraw the money from the contract address
• how to verify the contract, estimate gas, and deploy the app to Vercel

You can play with the demo at https://closesea-one.vercel.app/, which uses the contract deployed on Rinkeby - you need to connect your wallet, switch to Rinkeby network, and use test Rinkeby eth to list and trade.

The listed/minted NFTs can be seen at https://testnets.opensea.io/collection/closesea-collection.

The code and docs can be accessed at Repo.

The followings are used in this project:

• Solidity
• Hardhat
• Alchemy
• Rinkeby/Mumbai/Polygon
• OpenZeppelin
• Ethers.js
• Next.js
• TailwindCSS
