Turn Anything into an NFT with NFTPort and OpenSea

— Juliet Edjere

NFTs offer artists the opportunity to sell their work to collectors and other digital creators. Owners or creators stand to receive royalties for the copy or use of the work online.

If you're an art collector, you may be wondering how to mint NFTs to monetize your work if you have no previous blockchain experience.

So What is an NFT?

Quite simply an NFT is a unique digital asset that is not directly replaceable with another digital asset.

It is impossible to replace, copy or fake an NFT exactly, as each one is unique with its own attributes and are authenticated through the blockchain. Therefore, it is non-fungible.

Let’s get into it - this post will guide you through the journey.

Get an Ethereum wallet

If you want to mint to your own wallet, you will need to provide your own wallet address. You need an Ethereum wallet to use OpenSea.

A crypto wallet is an application or hardware device that allows individuals to store and retrieve digital items.

For this, I recommend Metamask. MetaMask has been the most preferred Ethereum wallet since it came into existence.

MetaMask is a software cryptocurrency wallet used to interact with the Ethereum blockchain. It allows users to access their Ethereum wallet through a browser extension or mobile app, which can then be used to interact with decentralized applications.

Through using a global API, users are able to connect their Ethereum accounts to various applications under the same network.

Easy minting with a single API call

Minting is the process of creating the NFT and adding it into the blockchain. Once added, you will not be able to make any further edits.

If you don’t know how to mint NFTs, retrieve NFT data, create NFT apps, or make NFT API pulls, you can use NFTPort. Using NFTPort minting APIs, you can turn anything into an NFT for free in less than 5 minutes using one simple API call.
