OpenSea platform and the Polygon (MATIC) blockchain. This is because choosing these is one of the ways you can create NFTs without paying gas fees (which are necessary, and potentially quite pricey, if you mint an NFT on the Ethereum blockchain, for example).
If you need to pay gas fees (the price required to conduct a transaction on a blockchain) when creating an NFT, you will need to sell the NFT for a much higher price in order to make any profit because you will need to at least cover the gas fees that were paid. That is not easy to do… for most artists, at least.
Without further ado, here is a step-by-step tutorial on what you need to do:
1. Connect an ETH Wallet to OpenSea
First, you’ll need to connect an Ethereum wallet to OpenSea. It can be completely empty — you don’t need to own any cryptocurrency. If you do not already have a wallet, I would recommend using either MetaMask or Coinbase Wallet. Both work well, are popular, and are easy to use.
