If you have no idea what NFT or Non-Fungible Tokens are, you can read the broad information about them in this article. The general idea about what makes an NFT is briefly discussed there under 500 seconds. But, if you have no time to read the article, I will still try to explain it here.
NFTs or Non-Fungible Tokens are digital assets of their physical counterparts. Either coded using ERC-721 or ERC-1155. If you have Ethereum, the official protocol of the tokens in your crypto wallet is created using ERC-20. Basically, it is a type of platform under the umbrella of the Ethereum blockchain.
HOW DO I START SELLING MY ARTWORKS AS AN NFT?
First, you must set up your crypto wallet. You can find crypto-wallets that have access to various coins. But I suggest you use decentralized wallets such as MetaMask and TrustWallet.
[Once you set up your wallets, don't forget to save the seed phrases so if ever you accidentally uninstall the app, you can still revive the crypto money you have deposited inside.]
Now that you have a wallet, open up your ETH wallet by clicking the "receive" button. An unhackable address will be generated that starts with “0x” and followed by random 40 characters. Copy your ETH address and save it into your locked notes.
Second, look for a decent website that offers public market for NTFs.
I listed some of them below:
And soon and that is about to launch is:
StudentCoin.app
Once you've chosen a platform where to create, sell, or buy your works, you can freely withdraw the Ethereum back to the crypto wallet of your choosing that you could, later on, get exchanged into fiat.
Good luck with your NFT journey!
