NFTs, or Non-Fungible Tokens, are unique digital assets that can represent objects such as works of art, music, videos, video game elements and more.

Creating NFTs
Choose a digital object: Select the item you want to transform into an NFT. This could be an image, video, audio file or other form of digital media.
Use an NFT creation platform: Platforms such as OpenSea, Rarible, or Mintable allow users to create (or ‘mint’) NFTs.
You will need to create an account on one of these platforms.
Connect a crypto-currency wallet: NFT transactions are generally made in crypto-currencies, mainly Ethereum (ETH). You will therefore need to have a crypto-currency wallet (such as MetaMask) connected to the platform.
Upload your file: Upload the digital file you want to transform into an NFT to the platform.
Add details: Provide information about your NFT, such as the title, description, and any specific attributes or properties.
Create (or ‘mint’) the NFT: Follow the steps on the platform to create your NFT. This usually involves paying a transaction fee in ETH.

Selling NFTs
Listing the NFT for sale: Once the NFT has been created, you can list it on a marketplace. The same platforms mentioned above (OpenSea, Rarible, Mintable) can be used to list and sell NFTs.
Set a price: Determine the price at which you want to sell your NFT. You can choose a fixed price, or put your NFT up for auction.
Promote your NFT: Share your NFT on social networks and in communities of NFT collectors to attract potential buyers.
Transaction: When someone buys your NFT, the transaction will be processed on the blockchain. You will receive payment in crypto-currency in your wallet.
Transfer of ownership: Once the transaction is confirmed, ownership of the NFT is transferred to the buyer.
