What is minting an NFT?

Minting an NFT refers to tokenising a digital file and transferring it to the blockchain where it is stored and can be transferred to and fro between multiple buyers and sellers. 

Putting your NFT up for sale is relatively easy. However, if you’re minting your first NFT, there are a few charges you need to know about before you get started.

Gas fees when listing a new item.

First up, Opensea charges a 2.5% service fee on every transaction on the platform. Other than that, there are gas fees involved with making transactions on the Ethereum blockchain, which has the most number of NFTs on it at the moment. 

For first-timers, Opensea requires a small transaction to be made to your wallet of choice so they can verify the authenticity of the account. This transaction will need you to pay a gas fee. Also, keep in mind that gas fees aren’t fixed and can fluctuate a lot based on the activity on the blockchain. 

Now that you’re aware of the charges, let’s mint your first NFT on Opensea. 

Step 1: Head over to the Opensea website and tap on the profile icon in the top-right.

Step 2: You’ll be asked to connect your wallet to Opensea. We’re using MetaMask, but you can use any wallet of your choice. 

Do keep in mind that different wallets have a different registration process. MetaMask works by installing itself as a browser extension and requires a unique key each time you login to your wallet. Your experience may vary based on the wallet you choose.
