Minting an NFT is the process of converting the ordinary jpeg, audio, or video file into a digital/ crypto asset by just uploading it into the Ethereum, Solana, Cardano, or Polkadot blockchain.
Among these blockchains, Ethereum and Solana are the most popular when it comes to NFT.

5. Initializing your wallet
Before listing for sale, OpenSea will ask you to confirm a few things.
Since this is your first time selling on OpenSea, you need to initialize your wallet. Meaning you need to pay a one-time gas fee.
If there is no sufficient funds in your wallet, the Confirm button won’t appear.
If you are done with the initialization, you need to confirm a few other things as well.
OpenSea wants you to approve the item for Sale and price confirmation.
Just confirm it through your wallet.
That’s it. Your NFT is up for sale.
7. Minting on other blockchains
Cross-blockchain support is available in OpenSea via Polygon; this is called bridging. Through which you can sell your NFT in a separate blockchain without paying any gas fee.
To mint via Polygon, go to step 4. After filling your name and description of your NFT, scroll down a bit. You could see a field called Blockchain in which you can select Polygon.
