We know that NFTs are very hot right now, NFTs also known as ERC-721 were a token standard that was created on the Ethereum platform.
NFT stands for Non-fungible token which means they are unique from each other and one NFT is not interchangeable with another token of its class.
for example, one dollar can be interchangeable with another dollar that is a fungible token and its contrast is NFTs for example a trading card or a unique piece of art.
it is also represented as digital pieces of art that are incorruptible and has a permanent history of who owns them who deployed them etc.
NFTs are deployed on a smart-contract platform and you can view them on different NFT platforms like Open Sea or any other platform you can obviously do this without a marketplace because it's decentralized but they help in giving a good interface.
That's it, for now,
