In Tatum, we have created an instantly deployable NFT marketplace smart contract that allows you to create fixed-price, peer-to-peer, NFT listings at the blockchain level. Once an NFT is sold, the funds are automatically transferred to the seller, the NFT to the buyer, and the marketplace fee to the marketplace owner.
You can sell NFTs for native assets (i.e. ETH on Ethereum or MATIC on Polygon) or for ERC20 tokens. If you want to sell NFTs for ERC20 tokens, there are a few extra steps you'll need to take, and we'll show you exactly how to do it in this video.
